COMMISSION REGULATION (EU) 2017/1151

of 1 June 2017

supplementing Regulation (EC) No 715/2007 of the European Parliament and of the Council on type-approval of motor vehicles with respect to emissions from light passenger and commercial vehicles (Euro 5 and Euro 6) and on access to vehicle repair and maintenance information, amending Directive 2007/46/EC of the European Parliament and of the Council, Commission Regulation (EC) No 692/2008 and Commission Regulation (EU) No 1230/2012 and repealing Commission Regulation (EC) No 692/2008

(Text with EEA relevance)

THE EUROPEAN COMMISSION,

Having regard to the Treaty on the Functioning of the European Union,

Having regard to Regulation (EC) No 715/2007 of the European Parliament and of the Council of 20 June 2007 on type-approval of motor vehicles with respect to emissions from light passenger and commercial vehicles (Euro 5 and Euro 6) and on access to vehicle repair and maintenance information (1), and in particular Articles 8 and 14(3) thereof,

Having regard to Directive 2007/46/EC of the European Parliament and of the Council of 5 September 2007 establishing a framework for the approval of motor vehicles and their trailers, and of systems, components and separate technical units intended for such vehicles (Framework Directive) (2), and in particular Article 39(2) thereof.

Whereas:

 

(1)

Commission Regulation (EC) No 692/2008 implementing and amending Regulation (EC) No 715/2007 (3) provides for light-duty vehicles to be tested in accordance with the New European Driving Cycle (NEDC).

 

(2)

Based on the continuous review of the relevant procedures, test cycles and test results provided for in Article 14(3) of Regulation (EC) No 715/2007, it is evident that the information about fuel consumption and CO2 emissions provided by testing vehicles in accordance with the NEDC is no longer adequate and no longer reflects real world emissions.

 

(3)

Against that background, it is appropriate to provide for a new regulatory test procedure by implementing the Worldwide harmonised Light-duty vehicles Test Procedures (WLTP) into Union legislation.

 

(4)

The WLTP was developed at the level of the United Nations Economic Commission for Europe (UNECE) and was adopted as Global Technical Regulation (GTR) No 15 by the World Forum for Harmonization of Vehicle Regulations (WP.29) in March 2014.

 

(5)

In addition to more realistic information about fuel consumption and CO2 emissions for consumer and regulatory purposes, the WLTP also creates a global framework for vehicle testing, leading to a closer international harmonisation of test requirements.

 

(6)

The WLTP provides a full description of a vehicle test cycle for CO2 and regulated pollutant emissions under standardised ambient conditions. In order to adapt it to the EU type-approval system, it is necessary to complement it by further improving the transparency requirements for technical parameters that will allow independent parties to reproduce the type approval test results and by reducing testing flexibilities.

 

(7)

This proposal also specifies a revised procedure for the conformity of production (CoP) assessment of vehicles. Since under the new provisions the CoP evolution coefficient as described in point 4.2.4.1 of Annex I is likely to be determined more often by specific testing of the manufacturer instead of using a default value, the respective test procedure will need to be revised in due course.

 

(8)

While the WLTP specifies a new test cycle and procedure for measuring emissions, other obligations, such as those linked to durability of pollution control devices, in-service conformity or consumer information on CO2 emissions and fuel consumption, remain essentially the same as those laid down in Regulation (EC) No 692/2008.

 

(9)

In order to allow approval authorities and manufacturers to put in place the necessary procedures to comply with the requirements of this Regulation, as well as to follow as much as possible the established calendar for the application of emissions requirements, it should apply to new type-approvals from 1 September 2017 in the case of categories M1, M2 and category N1 class I vehicles and from 1 September 2018 in the case of N1 vehicles of class II and III and category N2 vehicles, and to new vehicles from 1 September 2018 in the case of categories M1, M2 and category N1 class I vehicles, and from 1 September 2019 in the case of N1 vehicles of class II and III and category N2 vehicles.

 

(10)

As the purpose of this Regulation is the introduction of the WLTP into European legislation, the timetable and the transitional provisions for introducing the real driving emissions test procedure remain unchanged with respect to those lined out previously in Commission Regulations (EU) 2016/427 (4) and (EU) 2016/646 (5).

 

(11)

The measures provided for in this Regulation are in accordance with the opinion of the Technical Committee – Motor Vehicles,

    CONFORMITY OF PRODUCTION

4.1.   Introduction

 
 

4.1.1.

Every vehicle produced under a Type Approval according to this Regulation shall be so manufactured as to conform to the type approval requirements of this Regulation. The Manufacturer shall implement adequate arrangements and documented control plans and carry-out at specified intervals as given in this regulation the necessary emission and OBD tests to verify continued conformity with the approved type. The approval authority shall verify and agree with these arrangements and control plans of the manufacturer and perform audits and conduct emission and OBD tests at specific intervals, as given in this regulation, at the premises of the manufacturer, including production and test facilities as part of the product conformity and continued verification arrangements as described in Annex X of Directive 2007/46/EC.

 
 

4.1.2.

The manufacturer shall check the conformity of production by testing the emissions of pollutants (given in Table 2 of Annex I to Regulation (EC) No 715/2007), the emission of CO2 (along with the measurement of electric energy consumption, EC), the crankcase emissions, evaporative emissions and the OBD. The verification shall therefore include the tests of types 1, 3, 4 and the test for OBD, as described in section 2.4 of this Annex and the relevant annexes quoted therein. The specific procedures for conformity of production are set out in Sections 4.2 to 4.7 and Appendixes 1 and 2.

 
 

4.1.3.

For the purposes of the manufactures conformity of production check, the family means the CO2 interpolation family for tests of Type 1 and 3, includes for the Type 4 test the extensions described in paragraph 3.2 of this Annex and the OBD family with the extensions described in paragraph 3.3 of this Annex for the OBD tests.

 
 

4.1.4.

The frequency for product verification performed by the manufacturer shall be based on a risk assessment methodology consistent with the international standard ISO 31000:2009 — Risk Management — Principles and guidelines and at least for Type 1 with a minimum frequency of one verification per 5 000 vehicles produced per family or once per year, whichever comes first.

 
 

4.1.5.

The Approval Authority which has granted type-approval may at any time verify the conformity control methods applied in each production facility.

For the purpose of this regulation the Approval Authority shall perform audits for verifying the manufacturers arrangements and documented control plans at the premises of the manufacturer on a risk assessment methodology consistent with the international standard ISO 31000:2009 — Risk Management — Principles and guidelines and, in all cases, with a minimum frequency of one audit per year.

If the Approval Authority is not satisfied with the auditing procedure of the manufacturer, physical test shall directly be carried out on production vehicles as described in Sections 4.2 to 4.9.

 
 

4.1.6.

The normal frequency of physical test verifications by the Approval Authority shall be based on the results of the auditing procedure of the manufacturer on a risk assessment methodology and in all cases with a minimum frequency of one verification test per three years. The Approval Authority shall conduct these physical emission tests and OBD tests on production vehicles as described in Sections 4.2 to 4.9.

In the case of the manufacturer running the physical tests, the Approval Authority shall witness the tests at the manufacturer's facility.

 
 

4.1.7.

The Approval Authority shall report the results of all audit checks and physical tests performed on verifying conformity of the manufacturers and file it for a period of minimum 10 years. These reports should be available for other type approval authorities and the European Commission on request.

 
 

4.1.8.

In case of non-conformity Article 30 of Directive 2007/46/EC shall apply.

4.2.   Checking the conformity of the vehicle for a type 1 test

4.2.1.   The Type 1 test shall be carried out on production vehicles of a valid member of the CO2 interpolation family as described in the TA certificate. The limit values against which to check conformity for pollutants are set out in Table 2 of Annex I to Regulation (EC) No 715/2007. As regards CO2 emissions, the limit value shall be the value determined by the manufacturer for the selected vehicle in accordance with the interpolation methodology set out in Sub-Annex 7 of Annex XXI. The interpolation calculation shall be verified by the approval authority.

4.2.2.   A sample of three vehicles shall be selected at random in the family. After selection by the approval authority, the manufacturer shall not undertake any adjustment to the vehicles selected.

4.2.2.1.   The selection shall only include finalised production vehicles which have completed a maximum of 80 km and those vehicles will be referred to as zero km vehicles for the purposes of checking conformity against Type 1 test. The vehicle shall be tested on the appropriate WLTP cycle as described in Annex XXI to this Regulation notwithstanding the requirements for test repetitions, or km of vehicles. The test results shall be the values after all corrections according to this regulation are applied.

4.2.3.   The statistical method for calculating the test criteria is described in Appendix 1.

The production of a family shall be deemed to not conform when a fail decision is reached for one or more of the pollutants and CO2 values, according to the test criteria in Appendix 1.

The production of a family shall be deemed to conform once a pass decision is reached for all the pollutants and CO2 values according to the test criteria in Appendix 1.

When a pass decision has been reached for one pollutant, that decision shall not be changed by any additional tests carried out to reach a decision for the other pollutants and CO2 values.

If a pass decision is not reached for all the pollutants and CO2 values, a test shall be carried out on another vehicle, up to the maximum of 16 vehicles, and the procedure described in Appendix 1 for taking a pass or fail decision shall be repeated (see Figure I.4.2).

Figure I.4.2

Image

4.2.4.   At the request of the manufacturer and with the acceptance of the approval authority, tests may be carried out on a vehicle of the family with a maximum of 15 000 km in order to establish measured evolution coefficients EvC for pollutants/CO2 for each family. The running-in procedure shall be conducted by the manufacturer, who shall not to make any adjustments to these vehicles.

4.2.4.1.   In order to establish a measured evolution coefficient with a run-in vehicle the procedure shall be as follows:

 

(a)

the pollutants/CO2 shall be measured at a mileage of at most 80 km and at ‘x’ km of the first tested vehicle;

 

(b)

the evolution coefficient (EvC) of the pollutants/CO2 between 80 km and ‘x’ km shall be calculated as:

Formula

 

(c)

the other vehicles in the interpolation family shall not be run in, but their zero km emissions/EC/CO2 shall be multiplied by the evolution coefficient of the first run-in vehicle. In this case, the values to be taken for testing as in Appendix 1 shall be:

 

(i)

the values at ‘x’ km for the first vehicle;

 

(ii)

the values at zero km multiplied by the relevant evolution coefficient for the other vehicles.

4.2.4.2.   All these tests shall be conducted with commercial fuel. However, at the manufacturer’s request, the reference fuels described in Annex IX may be used.

4.2.4.3.   When checking the conformity of production for CO2, as an alternative to the procedure mentioned in Section 4.2.4.1 the vehicle manufacturer may use a fixed evolution coefficient EvC of 0,98 and multiply all values of CO2 measured at zero km by this factor.

4.2.5   Tests for conformity of production of vehicles fuelled by LPG or NG/biomethane may be performed with a commercial fuel of which the C3/C4 ratio lies between those of the reference fuels in the case of LPG, or of one of the high or low caloric fuels in the case of NG/biomethane. In all cases a fuel analysis shall be presented to the approval authority.

4.2.6.   Vehicles fitted with eco-innovations

 
 

4.2.6.1.

In the case of a vehicle type fitted with one or more eco-innovations, within the meaning of Article 12 of Regulation (EC) No 443/2009 for M1 vehicles or Article 12 of Regulation (EU) No 510/2011 for N1 vehicles, the conformity of production shall be demonstrated with respect to the eco-innovations, by checking the presence of the correct eco-innovation(s) in question.

3.3.   Preparation of the vehicle

The preparation of the vehicle shall include a general verification of the correct technical functioning of the test vehicle.

3.4.   Installation of PEMS

3.4.1.   General

The installation of the PEMS shall follow the instructions of the PEMS manufacturer and the local health and safety regulations. The PEMS should be installed as to minimize during the test electromagnetic interferences as well as exposure to shocks, vibration, dust and variability in temperature. The installation and operation of the PEMS shall be leak-tight and minimize heat loss. The installation and operation of PEMS shall not change the nature of the exhaust gas nor unduly increase the length of the tailpipe. To avoid the generation of particles, connectors shall be thermally stable at the exhaust gas temperatures expected during the test. It is recommended to avoid the use of a material which may emit volatile components to connect the vehicle exhaust outlet and the connecting tube. Elastomer connectors, if used, shall have a minimum exposure to the exhaust gas to avoid artefacts at high engine load.

3.4.2.   Permissible backpressure

The installation and operation of the PEMS shall not unduly increase the static pressure at the exhaust outlet. If technically feasible, any extension to facilitate the sampling or connection with the exhaust mass flow meter shall have an equivalent, or larger, cross sectional area than the exhaust pipe.

3.4.3.   Exhaust mass flow meter

Whenever used, the exhaust mass flow meter shall be attached to the vehicle's tailpipe(s) according to the recommendations of the EFM manufacturer. The measurement range of the EFM shall match the range of the exhaust mass flow rate expected during the test. The installation of the EFM and any exhaust pipe adaptors or junctions shall not adversely affect the operation of the engine or exhaust after-treatment system. A minimum of four pipe diameters or 150 mm of straight tubing, whichever is larger, shall be placed at either side of the flow-sensing element. When testing a multi-cylinder engine with a branched exhaust manifold, it is recommended to combine the manifolds upstream of the exhaust mass flow meter and to increase the cross section of the piping appropriately as to minimize backpressure in the exhaust. If this is not feasible, exhaust flow measurements with several exhaust mass flow meters shall be considered. The wide variety of exhaust pipe configurations, dimensions and exhaust mass flow rates may require compromises, guided by good engineering judgement, when selecting and installing the EFM(s). If measurement accuracy requires, it is permissible to install an EFM with a diameter smaller than that of the exhaust outlet or the total cross-sectional area of multiple outlets, providing it does not adversely affect the operation or the exhaust after-treatment as specified in point 3.4.2.

3.4.4.   Global Positioning System (GPS)

The GPS antenna should be mounted, e.g. at the highest possible location, as to ensure good reception of the satellite signal. The mounted GPS antenna shall interfere as little as possible with the vehicle operation.

3.4.5.   Connection with the Engine Control Unit (ECU)

If desired, relevant vehicle and engine parameters listed in Table 1 can be recorded by using a data logger connected with the ECU or the vehicle network through standards, such as ISO 15031-5 or SAE J1979, OBD-II, EOBD or WWH-OBD. If applicable, manufacturers shall disclose labels to allow the identification of required parameters.

3.4.6.   Sensors and auxiliary equipment

Vehicle speed sensors, temperature sensors, coolant thermocouples or any other measurement device not part of the vehicle shall be installed to measure the parameter under consideration in a representative, reliable and accurate manner without unduly interfering with the vehicle operation and the functioning of other analysers, flow-measuring instruments, sensors and signals. Sensors and auxiliary equipment shall be powered independently of the vehicle. It is permitted to power any safety-related illumination of fixtures and installations of PEMS components outside of the vehicle’s cabin by the vehicle’s battery.

3.5.   Emissions sampling

Emissions sampling shall be representative and conducted at locations of well-mixed exhaust where the influence of ambient air downstream of the sampling point is minimal. If applicable, emissions shall be sampled downstream of the exhaust mass flow meter, respecting a distance of at least 150 mm to the flow sensing element. The sampling probes shall be fitted at least 200 mm or three times the inner diameter of the exhaust pipe, whichever is larger, upstream of the point at which the exhaust exits the PEMS sampling installation into the environment. If the PEMS feeds back a flow to the tail pipe, this shall occur downstream of the sampling probe in a manner that does not affect during engine operation the nature of the exhaust gas at the sampling point(s). If the length of the sampling line is changed, the system transport times shall be verified and if necessary corrected.

If the engine is equipped with an exhaust after-treatment system, the exhaust sample shall be taken downstream of the exhaust after-treatment system. When testing a vehicle with a multi-cylinder engine and branched exhaust manifold, the inlet of the sampling probe shall be located sufficiently far downstream so as to ensure that the sample is representative of the average exhaust emissions of all cylinders. In multi-cylinder engines, having distinct groups of manifolds, such as in a ‘V’ engine configuration, the manifolds shall be combined upstream of the sampling probe. If this is technically not feasible, multi-point sampling at locations of well-mixed exhaust free of ambient air shall be considered. In this case, the number and location of sampling probes shall match as far as possible those of the exhaust mass flow meters. In case of unequal exhaust flows, proportional sampling or sampling with multiple analysers shall be considered.

If particles are measured, the exhaust shall be sampled from the centre of the exhaust stream. If several probes are used for emissions sampling, the particle sampling probe shall be placed upstream of the other sampling probes.

If hydrocarbons are measured, the sampling line shall be heated to 463 ± 10 K (190 ± 10 °C). For the measurement of other gaseous components with or without cooler, the sampling line shall be kept at a minimum of 333 K (60 °C) to avoid condensation and to ensure appropriate penetration efficiencies of the various gases. For low pressure sampling systems, the temperature can be lowered corresponding to the pressure decrease provided that the sampling system ensures a penetration efficiency of 95 % for all regulated gaseous pollutants. If particles are sampled, the sampling line from the raw exhaust sample point shall be heated to a minimum of 373 K (100 °C). The residence time of the sample in the particle sampling line shall be less than 3 s until reaching first dilution or the particle counter.

  • 4. 
    PRE-TEST PROCEDURES

4.1.   PEMS leak check

After the installation of the PEMS is completed, a leak check shall be performed at least once for each PEMS-vehicle installation as prescribed by the PEMS manufacturer or as follows. The probe shall be disconnected from the exhaust system and the end plugged. The analyser pump shall be switched on. After an initial stabilization period all flow meters shall read approximately zero in the absence of a leak. Else, the sampling lines shall be checked and the fault be corrected.

The leakage rate on the vacuum side shall not exceed 0.5 per cent of the in-use flow rate for the portion of the system being checked. The analyser flows and bypass flows may be used to estimate the in-use flow rate.

Alternatively, the system may be evacuated to a pressure of at least 20 kPa vacuum (80 kPa absolute). After an initial stabilization period the pressure increase Δp (kPa/min) in the system shall not exceed:

Formula

Alternatively, a concentration step change at the beginning of the sampling line shall be introduced by switching from zero to span gas while maintaining the same pressure conditions as under normal system operation. If for a correctly calibrated analyser after an adequate period of time the reading is ≤ 99 per cent compared to the introduced concentration, the leakage problem shall be corrected.

4.2.   Starting and stabilizing the PEMS

The PEMS shall be switched on, warmed up and stabilized according to the specifications of the PEMS manufacturer until, e.g., pressures, temperatures and flows have reached their operating set points.

4.3.   Preparing the sampling system

The sampling system, consisting of the sampling probe, sampling lines and the analysers, shall be prepared for testing by following the instruction of the PEMS manufacturer. It shall be ensured that the sampling system is clean and free of moisture condensation.

4.4.   Preparing the Exhaust mass Flow Meter (EFM)

If used for measuring the exhaust mass flow, the EFM shall be purged and prepared for operation in accordance with the specifications of the EFM manufacturer. This procedure shall, if applicable, remove condensation and deposits from the lines and the associated measurement ports.

4.5.   Checking and calibrating the analysers for measuring gaseous emissions

Zero and span calibration adjustments of the analysers shall be performed using calibration gases that meet the requirements of point 5 of Appendix 2. The calibration gases shall be chosen to match the range of pollutant concentrations expected during the RDE test. To minimize analyser drift, one should conduct the zero and span calibration of analysers at an ambient temperature that resembles, as closely as possible, the temperature experienced by the test equipment during the trip.

4.6.   Checking the analyser for measuring particle emissions

The zero level of the analyser shall be recorded by sampling HEPA filtered ambient air. The signal shall be recorded at a constant frequency of at least 1.0 Hz over a period of 2 min and averaged; the permissible concentration value shall be determined once suitable measurement equipment becomes available.

4.7.   Determining vehicle speed

Vehicle speed shall be determined by at least one of the following methods:

 

(a)

a GPS; if vehicle speed is determined by a GPS, the total trip distance shall be checked against the measurements of another method according to point 7 of Appendix 4.

 

(b)

a sensor (e.g., optical or micro-wave sensor); if vehicle speed is determined by a sensor, the speed measurements shall comply with the requirements of point 8 of Appendix 2, or alternatively, the total trip distance determined by the sensor shall be compared with a reference distance obtained from a digital road network or topographic map. The total trip distance determined by the sensor shall deviate by no more than 4 % from the reference distance.

 

(c)

the ECU; if vehicle speed is determined by the ECU, the total trip distance shall be validated according to point 3 of Appendix 3 and the ECU speed signal adjusted, if necessary to fulfil the requirements of point 3.3 of Appendix 3. Alternatively, the total trip distance as determined by the ECU can be compared with a reference distance obtained from a digital road network or topographic map. The total trip distance determined by the ECU shall deviate by no more than 4 % from the reference.

4.8.   Check of PEMS set up

The correctness of connections with all sensors and, if applicable, the ECU shall be verified. If engine parameters are retrieved, it shall be ensured that the ECU reports values correctly (e.g., zero engine speed [rpm] while the combustion engine is in key-on-engine-off status). The PEMS shall function free of warning signals and error indication.

    EMISSIONS TEST

5.1.   Test start

Sampling, measurement and recording of parameters shall begin prior to the start of the engine. To facilitate time alignment, it is recommended to record the parameters that are subject to time alignment either by a single data recording device or with a synchronised time stamp. Before and directly after engine start, it shall be confirmed that all necessary parameters are recorded by the data logger.

5.2.   Test

Sampling, measurement and recording of parameters shall continue throughout the on-road test of the vehicle. The engine may be stopped and started, but emissions sampling and parameter recording shall continue. Any warning signals, suggesting malfunctioning of the PEMS, shall be documented and verified. Parameter recording shall reach a data completeness of higher than 99 %. Measurement and data recording may be interrupted for less than 1 % of the total trip duration but for no more than a consecutive period of 30 s solely in the case of unintended signal loss or for the purpose of PEMS system maintenance. Interruptions may be recorded directly by the PEMS. It is not permissible to introduce interruptions in the recorded parameter via the pre-processing, exchange or post-processing of data. If conducted, auto zeroing shall be performed against a traceable zero standard similar to the one used to zero the analyser. If necessary it is strongly recommended to initiate PEMS system maintenance during periods of zero vehicle speed.

5.3.   Test end

The end of the test is reached when the vehicle has completed the trip and the combustion engine is switched off. Excessive idling of the engine after the completion of the trip shall be avoided. The data recording shall continue until the response time of the sampling systems has elapsed.

  • 6. 
    POST-TEST PROCEDURE

6.1.   Checking the analysers for measuring gaseous emissions

The zero and span of the analysers of gaseous components shall be checked by using calibration gases identical to the ones applied under point 4.5 to evaluate the analyser's zero and response drift compared to the pre-test calibration. It is permissible to zero the analyser prior to verifying the span drift, if the zero drift was determined to be within the permissible range. The post-test drift check shall be completed as soon as possible after the test and before the PEMS, or individual analysers or sensors, are turned off or have switched into a non-operating mode. The difference between the pre-test and post-test results shall comply with the requirements specified in Table 2.

6.2.   Checking the analyser for measuring particle emissions

The zero level of the analyser shall be recorded by sampling HEPA filtered ambient air. The signal shall be recorded over a period of 2 min and averaged; the permissible final concentration shall be defined once suitable measurement equipment becomes available. If the difference between the pre-test and post-test check is higher than permitted, all test results shall be voided and the test repeated.

6.3.   Checking the on-road emission measurements

The calibrated range of the analysers shall account at least for 90 % of the concentration values obtained from 99 % of the measurements of the valid parts of the emissions test. It is permissible that 1 % of the total number of measurements used for evaluation exceeds the calibrated range of the analysers by up to a factor of two.

3.1.   General

The linearity of analysers, flow-measuring instruments, sensors and signals, shall be traceable to international or national standards. Any sensors or signals that are not directly traceable, e.g., simplified flow-measuring instruments shall be calibrated alternatively against chassis dynamometer laboratory equipment that has been calibrated against international or national standards.

3.2.   Linearity requirements

3.3.   Frequency of linearity verification

The linearity requirements according to point 3.2 shall be verified:

 

(a)

for each analyser at least every three months or whenever a system repair or change is made that could influence the calibration;

 

(b)

for other relevant instruments, such as exhaust mass flow meters and traceably calibrated sensors, whenever damage is observed, as required by internal audit procedures, by the instrument manufacturer or by ISO 9000 but no longer than one year before the actual test.

The linearity requirements according to point 3.2 for sensors or ECU signals that are not directly traceable shall be performed with a traceably calibrated measurement device on the chassis dynamometer once for each PEMS setup.

3.4.   Procedure of linearity verification

3.4.1.   General requirements

The relevant analysers, instruments and sensors shall be brought to their normal operating condition according to the recommendations of their manufacturer. The analysers, instruments and sensors shall be operated at their specified temperatures, pressures and flows.

3.4.2.   General procedure

The linearity shall be verified for each normal operating range by executing the following steps:

 

(a)

The analyser, flow-measuring instrument or sensor shall be set to zero by introducing a zero signal. For gas analysers, purified synthetic air or nitrogen shall be introduced to the analyser port via a gas path that is as direct and short as possible.

 

(b)

The analyser, flow-measuring instrument or sensor shall be spanned by introducing a span signal. For gas analysers, an appropriate span gas shall be introduced to the analyser port via a gas path that is as direct and short as possible.

 

(c)

The zero procedure of (a) shall be repeated.

 

(d)

The linearity shall be verified by introducing at least 10, approximately equally spaced and valid, reference values (including zero). The reference values with respect to the concentration of components, the exhaust mass flow rate or any other relevant parameter shall be chosen to match the range of values expected during the emissions test. For measurements of exhaust mass flow, reference points below 5 % of the maximum calibration value can be excluded from the linearity verification.

 

(e)

For gas analysers, known gas concentrations in accordance with point 5 shall be introduced to the analyser port. Sufficient time for signal stabilisation shall be given.

 

(f)

The values under evaluation and, if needed, the reference values shall be recorded at a constant frequency of at least 1.0 Hz over a period of 30 seconds.

 

(g)

The arithmetic mean values over the 30 seconds period shall be used to calculate the least squares linear regression parameters, with the best-fit equation having the form:

Formula

where:

 

y

is the actual value of the measurement system

a 1

is the slope of the regression line

x

is the reference value

a 0

is the y intercept of the regression line

The standard error of estimate (SEE) of y on x and the coefficient of determination (r2) shall be calculated for each measurement parameter and system.

 

(h)

The linear regression parameters shall meet the requirements specified in Table 1.

3.4.3.   Requirements for linearity verification on a chassis dynamometer

Non-traceable flow-measuring instruments, sensors or ECU signals that cannot directly be calibrated according to traceable standards, shall be calibrated on a chassis dynamometer. The procedure shall follow as far as applicable, the requirements of Annex 4a to UN/ECE Regulation No 83. If necessary, the instrument or sensor to be calibrated shall be installed on the test vehicle and operated according to the requirements of Appendix 1. The calibration procedure shall follow whenever possible the requirements of point 3.4.2; at least 10 appropriate reference values shall be selected as to ensure that at least 90 % of the maximum value expected to occur during the RDE test is covered.

If a not directly traceable flow-measuring instrument, sensor or ECU signal for determining exhaust flow is to be calibrated, a traceably calibrated reference exhaust mass flow meter or the CVS shall be attached to the vehicle’s tailpipe. It shall be ensured that the vehicle exhaust is accurately measured by the exhaust mass flow meter according to point 3.4.3 of Appendix 1. The vehicle shall be operated by applying constant throttle at a constant gear selection and chassis dynamometer load.

(c)

a demonstration of equivalency with the respective standard analyser specified in point 4.1.1 with respect to the influence of atmospheric pressure on the measurement performance of the analyser; the demonstration test shall determine the response to span gas having a concentration within the analyser range to check the influence of atmospheric pressure under moderate and extended altitude conditions defined in point 5.2 of this Annex. Such a test can be performed in an altitude environmental test chamber.

 

(d)

a demonstration of equivalency with the respective standard analyser specified in point 4.1.1 over at least three on-road tests that fulfil the requirements of this Annex.

 

(e)

a demonstration that the influence of vibrations, accelerations and ambient temperature on the analyser reading does not exceed the noise requirements for analysers set out in point 4.2.4.

Approval authorities may request additional information to substantiate equivalency or refuse approval if measurements demonstrate that an alternative analyser is not equivalent to a standard analyser.

4.2.   Analyser specifications

In addition to the linearity requirements defined for each analyser in point 3, the compliance of analyser types with the specifications laid down in points 4.2.2 to 4.2.8 shall be demonstrated by the analyser manufacturer. Analysers shall have a measuring range and response time appropriate to measure with adequate accuracy the concentrations of the exhaust gas components at the applicable emissions standard under transient and steady state conditions. The sensitivity of the analysers to shocks, vibration, aging, variability in temperature and air pressure as well as electromagnetic interferences and other impacts related to vehicle and analyser operation shall be limited as far as possible.

The noise, defined as two times the root mean square of ten standard deviations, each calculated from the zero responses measured at a constant recording frequency of at least 1.0 Hz during a period of 30 seconds, shall not exceed 2 % of full scale. Each of the 10 measurement periods shall be interspersed with an interval of 30 seconds in which the analyser is exposed to an appropriate span gas. Before each sampling period and before each span period, sufficient time shall be given to purge the analyser and the sampling lines.

4.2.5.   Zero response drift

4.2.8.   Gas drying

Exhaust gases may be measured wet or dry. A gas-drying device, if used, shall have a minimal effect on the composition of the measured gases. Chemical dryers are not permitted.

4.3.   Additional requirements

4.3.1.   General

The provisions in points 4.3.2 to 4.3.5 define additional performance requirements for specific analyser types and apply only to cases, in which the analyser under consideration is used for RDE emission measurements.

4.3.2.   Efficiency test for NOX converters

If a NOX converter is applied, for example to convert NO2 into NO for analysis with a chemiluminescence analyser, its efficiency shall be tested by following the requirements of point 2.4 of Appendix 3 of Annex 4a to UN/ECE Regulation No 83, 07 series of amendments. The efficiency of the NOX converter shall be verified no longer than one month before the emissions test.

4.3.3.   Adjustment of the Flame Ionisation Detector (FID)

(a)   Optimization of the detector response

If hydrocarbons are measured, the FID shall be adjusted at intervals specified by the analyser manufacturer by following point 2.3.1 of Appendix 3 of Annex 4a to UN/ECE Regulation No 83, 07 series of amendments. A propane-in-air or propane-in-nitrogen span gas shall be used to optimize the response in the most common operating range.

(b)   Hydrocarbon response factors

If hydrocarbons are measured, the hydrocarbon response factor of the FID shall be verified by following the provisions of point 2.3.3 of Appendix 3 of Annex 4a to UN/ECE Regulation No 83, 07 series of amendments, using propane-in-air or propane-in-nitrogen as span gases and purified synthetic air or nitrogen as zero gases, respectively.

(c)   Oxygen interference check

The oxygen interference check shall be performed when introducing a FID into service and after major maintenance intervals. A measuring range shall be chosen in which the oxygen interference check gases fall in the upper 50 per cent. The test shall be conducted with the oven temperature set as required. The specifications of the oxygen interference check gases are described in point 5.3.

The following procedure applies:

 

(i)

The analyser shall be set at zero;

 

(ii)

The analyser shall be spanned with a 0 per cent oxygen blend for positive ignition engines and a 21 per cent oxygen blend for compression ignition engines;

 

(iii)

The zero response shall be rechecked. If it has changed by more than 0.5 per cent of full scale, steps (i) and (ii) shall be repeated;

 

(iv)

The 5 per cent and 10 per cent oxygen interference check gases shall be introduced;

 

(v)

The zero response shall be rechecked. If it has changed by more than ±1 per cent of full scale, the test shall be repeated;

 

(vi)

The oxygen interference E O2 shall be calculated for each oxygen interference check gas in step (iv) as follows:

Formula

where the analyser response is:

Formula

where:

 

c ref,b

is the reference HC concentration in step (ii) [ppmC1]

c ref,d

is the reference HC concentration in step (iv) [ppmC1]

c FS,b

is the full scale HC concentration in step (ii) [ppmC1]

c FS,d

is the full scale HC concentration in step (iv) [ppmC1]

c m,b

is the measured HC concentration in step (ii) [ppmC1]

c m,d

is the measured HC concentration in step (iv) [ppmC1]

 

(vii)

The oxygen interference E O2 shall be less than ±1.5 per cent for all required oxygen interference check gases.

 

(viii)

If the oxygen interference E O2 is higher than ±1.5 per cent, corrective action may be taken by incrementally adjusting the air flow (above and below the manufacturer's specifications), the fuel flow and the sample flow.

 

(ix)

The oxygen interference check shall be repeated for each new setting.

4.3.4.   Conversion efficiency of the non-methane cutter (NMC)

If hydrocarbons are analysed, a NMC can be used to remove non-methane hydrocarbons from the gas sample by oxidizing all hydrocarbons except methane. Ideally, the conversion for methane is 0 per cent and for the other hydrocarbons represented by ethane is 100 per cent. For the accurate measurement of NMHC, the two efficiencies shall be determined and used for the calculation of the NMHC emissions (see point 9.2 of Appendix 4). It is not necessary to determine the methane conversion efficiency in case the NMC-FID is calibrated according to method (b) in point 9.2 of Appendix 4 by passing the methane/air calibration gas through the NMC.

(a)   Methane conversion efficiency

Methane calibration gas shall be flown through the FID with and without bypassing the NMC; the two concentrations shall be recorded. The methane efficiency shall be determined as:

Formula

where:

 

c HC(w/NMC)

is the HC concentration with CH4 flowing through the NMC [ppmC1]

c HC(w/o NMC)

is the HC concentration with CH4 bypassing the NMC [ppmC1]

(b)   Ethane conversion efficiency

Ethane calibration gas shall be flown through the FID with and without bypassing the NMC; the two concentrations shall be recorded. The ethane efficiency shall be determined as:

Formula

where:

 

c HC(w/NMC)

is the HC concentration with C2H6 flowing through the NMC [ppmC1]

c HC(w/o NMC)

is the HC concentration with C2H6 bypassing the NMC [ppmC1]

4.3.5.   Interference effects

(a)   General

Other gases than the ones being analysed can affect the analyser reading. A check for interference effects and the correct functionality of analysers shall be performed by the analyser manufacturer prior to market introduction at least once for each type of analyser or device addressed in points (b) to (f).

(b)   CO analyser interference check

Water and CO2 can interfere with the measurements of the CO analyser. Therefore, a CO2 span gas having a concentration of 80 to 100 per cent of full scale of the maximum operating range of the CO analyser used during the test shall be bubbled through water at room temperature and the analyser response recorded. The analyser response shall not be more than 2 per cent of the mean CO concentration expected during normal on-road testing or ± 50 ppm, whichever is larger. The interference check for H2O and CO2 may be run as separate procedures. If the H2O and CO2 levels used for the interference check are higher than the maximum levels expected during the test, each observed interference value shall be scaled down by multiplying the observed interference with the ratio of the maximum expected concentration value during the test and the actual concentration value used during this check. Separate interference checks with concentrations of H2O that are lower than the maximum concentration expected during the test may be run and the observed H2O interference shall be scaled up by multiplying the observed interference with the ratio of the maximum H2O concentration value expected during the test and the actual concentration value used during this check. The sum of the two scaled interference values shall meet the tolerance specified in this point.

(c)   NOX analyser quench check

The two gases of concern for CLD and HCLD analysers are CO2 and water vapour. The quench response to these gases is proportional to the gas concentrations. A test shall determine the quench at the highest concentrations expected during the test. If the CLD and HCLD analysers use quench compensation algorithms that utilize H2O or CO2 measurement analysers or both, quench shall be evaluated with these analysers active and with the compensation algorithms applied.

(i)   CO2 quench check

A CO2 span gas having a concentration of 80 to 100 per cent of the maximum operating range shall be passed through the NDIR analyser; the CO2 value shall be recorded as A. The CO2 span gas shall then be diluted by approximately 50 per cent with NO span gas and passed through the NDIR and CLD or HCLD; the CO2 and NO values shall be recorded as B and C, respectively. The CO2 gas flow shall then be shut off and only the NO span gas shall be passed through the CLD or HCLD; the NO value shall be recorded as D. The per cent quench shall be calculated as:

Formula

where:

 

A

is the undiluted CO2 concentration measured with the NDIR [%]

B

is the diluted CO2 concentration measured with the NDIR [%]

C

is the diluted NO concentration measured with the CLD or HCLD [ppm]

D

is the undiluted NO concentration measured with the CLD or HCLD [ppm]

Alternative methods of diluting and quantifying of CO2 and NO span gas values such as dynamic mixing/blending are permitted upon approval of the approval authority.

(ii)   Water quench check

This check applies to measurements of wet gas concentrations only. The calculation of water quench shall consider dilution of the NO span gas with water vapour and the scaling of the water vapour concentration in the gas mixture to concentration levels that are expected to occur during an emissions test. A NO span gas having a concentration of 80 per cent to 100 per cent of full scale of the normal operating range shall be passed through the CLD or HCLD; the NO value shall be recorded as D. The NO span gas shall then be bubbled through water at room temperature and passed through the CLD or HCLD; the NO value shall be recorded as C. The analyser's absolute operating pressure and the water temperature shall be determined and recorded as E and F, respectively. The mixture's saturation vapour pressure that corresponds to the water temperature of the bubbler F shall be determined and recorded as G. The water vapour concentration H [%] of the gas mixture shall be calculated as:

Formula

The expected concentration of the diluted NO-water vapour span gas shall be recorded as D e after being calculated as:

Formula

For diesel exhaust, the maximum concentration of water vapour in the exhaust gas (in per cent) expected during the test shall be recorded as H m after being estimated, under the assumption of a fuel H/C ratio of 1.8/1, from the maximum CO2 concentration in the exhaust gas A as follows:

Formula

The per cent water quench shall be calculated as:

Formula

where:

 

D e

is the expected diluted NO concentration [ppm]

C

is the measured diluted NO concentration [ppm]

H m

is the maximum water vapour concentration [%]

H

is the actual water vapour concentration [%]

(iii)   Maximum allowable quench

The combined CO2 and water quench shall not exceed 2 per cent of full scale.

(d)   Quench check for NDUV analysers

Hydrocarbons and water can positively interfere with NDUV analysers by causing a response similar to that of NOX. The manufacturer of the NDUV analyser shall use the following procedure to verify that quench effects are limited:

 

(i)

The analyser and chiller shall be set up by following the operating instructions of the manufacturer; adjustments should be made as to optimise the analyser and chiller performance.

 

(ii)

A zero calibration and span calibration at concentration values expected during emissions testing shall be performed for the analyser.

 

(iii)

A NO2 calibration gas shall be selected that matches as far as possible the maximum NO2 concentration expected during emissions testing.

 

(iv)

The NO2 calibration gas shall overflow at the gas sampling system's probe until the NOX response of the analyser has stabilised.

 

(v)

The mean concentration of the stabilized NOX recordings over a period of 30 s shall be calculated and recorded as NOX,ref.

 

(vi)

The flow of the NO2 calibration gas shall be stopped and the sampling system saturated by overflowing with a dew point generator's output, set at a dew point of 50 °C. The dew point generator's output shall be sampled through the sampling system and chiller for at least 10 minutes until the chiller is expected to be removing a constant rate of water.

 

(vii)

Upon completion of (iv), the sampling system shall again be overflown by the NO2 calibration gas used to establish NOX,ref until the total NOX response has stabilized.

 

(viii)

The mean concentration of the stabilized NOX recordings over a period of 30 s shall be calculated and recorded as NOX,m.

 

(ix)

NOX,m shall be corrected to NOX,dry based upon the residual water vapour that passed through the chiller at the chiller's outlet temperature and pressure.

The calculated NOX,dry shall at least amount to 95 % of NOX,ref.

(e)   Sample dryer

A sample dryer removes water, which can otherwise interfere with the NOX measurement. For dry CLD analysers, it shall be demonstrated that at the highest expected water vapour concentration H m the sample dryer maintains the CLD humidity at ≤ 5 g water/kg dry air (or about 0.8 per cent H2O), which is 100 per cent relative humidity at 3.9 °C and 101.3 kPa or about 25 per cent relative humidity at 25 °C and 101.3 kPa. Compliance may be demonstrated by measuring the temperature at the outlet of a thermal sample dryer or by measuring the humidity at a point just upstream of the CLD. The humidity of the CLD exhaust might also be measured as long as the only flow into the CLD is the flow from the sample dryer.

(f)   Sample dryer NO2 penetration

Liquid water remaining in an improperly designed sample dryer can remove NO2 from the sample. If a sample dryer is used in combination with a NDUV analyser without an NO2/NO converter upstream, water could therefore remove NO2 from the sample prior to the NOX measurement. The sample dryer shall allow for measuring at least 95 per cent of the NO2 contained in a gas that is saturated with water vapour and consists of the maximum NO2 concentration expected to occur during emission testing.

4.4.   Response time check of the analytical system

For the response time check, the settings of the analytical system shall be exactly the same as during the emissions test (i.e. pressure, flow rates, filter settings in the analysers and all other parameters influencing the response time). The response time shall be determined with gas switching directly at the inlet of the sample probe. The gas switching shall be done in less than 0.1 second. The gases used for the test shall cause a concentration change of at least 60 per cent full scale of the analyser.

The concentration trace of each single gas component shall be recorded. The delay time is defined as the time from the gas switching (t 0) until the response is 10 per cent of the final reading (t 10). The rise time is defined as the time between 10 per cent and 90 per cent response of the final reading (t 90 – t 10). The system response time (t 90) consists of the delay time to the measuring detector and the rise time of the detector.

For time alignment of the analyser and exhaust flow signals, the transformation time is defined as the time from the change (t 0) until the response is 50 per cent of the final reading (t 50).

The system response time shall be ≤ 12 s with a rise time of ≤ 3 seconds for all components and all ranges used. When using a NMC for the measurement of NMHC, the system response time may exceed 12 seconds.

The span value of the instrument shall be adjusted with the span gas directly connected to the instrument.

It is permissible to calculate the exhaust mass flow rate based on air flow and fuel flow measurements obtained from traceably calibrated sensors if these fulfil the linearity requirements of point 3, the accuracy requirements of point 8 and if the resulting exhaust mass flow rate is validated according to point 4 of Appendix 3.

In addition, other methods that determine the exhaust mass flow rate based on not directly traceable instruments and signals, such as simplified exhaust mass flow meters or ECU signals are permissible if the resulting exhaust mass flow rate fulfils the linearity requirements of point 3 and is validated according to point 4 of Appendix 3.

The response time determination shall be done with gas switching directly at the inlet of the exhaust mass flow meter. The gas flow switching shall be done as fast as possible, but highly recommended in less than 0,1 second. The gas flow rate used for the test shall cause a flow rate change of at least 60 per cent full scale of the exhaust mass flow meter. The gas flow shall be recorded. The delay time is defined as the time from the gas flow switching (t 0) until the response is 10 per cent (t 10) of the final reading. The rise time is defined as the time between 10 per cent and 90 per cent response (t 90 – t 10) of the final reading. The response time (t 90) is defined as the sum of the delay time and the rise time. The exhaust mass flow meter response time (t90 ) shall be ≤ 3 seconds with a rise time (t 90 – t 10) of ≤ 1 second in accordance with point 7.2.8.

    TIME CORRECTION OF PARAMETERS

For the correct calculation of distance-specific emissions, the recorded traces of component concentrations, exhaust mass flow rate, vehicle speed, and other vehicle data shall be time corrected. To facilitate the time correction, data which are subject to time alignment shall be recorded either in a single data recording device or with a synchronised timestamp following point 5.1 of Appendix 1. The time correction and alignment of parameters shall be carried out by following the sequence described in points 3.1 to 3.3.

3.1.   Time correction of component concentrations

3.3.2.   Vehicle speed with exhaust mass flow rate

Vehicle speed shall be time aligned with the exhaust mass flow rate by cross-correlation between the exhaust mass flow rate and the product of vehicle speed and positive acceleration.

The cold start period covers the first 5 minutes after initial start of the combustion engine. If the coolant temperature can be reliably determined, the cold start period ends once the coolant has reached 343 K (70 °C) for the first time but no later than 5 min after initial engine start. Cold start emissions shall be recorded.

  • 5. 
    EMISSION MEASUREMENTS DURING ENGINE STOP

Any instantaneous emissions or exhaust flow measurements obtained while the combustion engine is deactivated shall be recorded. In a separate step, the recorded values shall afterward be set to zero by the data post processing. The combustion engine shall be considered as deactivated if two of the following criteria apply: the recorded engine speed is < 50 rpm; the exhaust mass flow rate is measured at < 3 kg/h; the measured exhaust mass flow rate drops to <15 % of the steady-state exhaust mass flow rate at idling.

  • 6. 
    CONSISTENCY CHECK OF VEHICLE ALTITUDE

In case well-reasoned doubts exist that a trip has been conducted above of the permissible altitude as specified in point 5.2 of this Annex and in case altitude has only been measured with a GPS, the GPS altitude data shall be checked for consistency and, if necessary, corrected. The consistency of data shall be checked by comparing the latitude, longitude and altitude data obtained from the GPS with the altitude indicated by a digital terrain model or a topographic map of suitable scale. Measurements that deviate by more than 40 m from the altitude depicted in the topographic map shall be manually corrected and marked.

  • 7. 
    CONSISTENCY CHECK OF GPS VEHICLE SPEED

The vehicle speed as determined by the GPS shall be checked for consistency by calculating and comparing the total trip distance with reference measurements obtained from either a sensor, the validated ECU or, alternatively, from a digital road network or topographic map. It is mandatory to correct GPS data for obvious errors, e.g., by applying a dead reckoning sensor, prior to the consistency check. The original and uncorrected data file shall be retained and any corrected data shall be marked. The corrected data shall not exceed an uninterrupted time period of 120 s or a total of 300 s. The total trip distance as calculated from the corrected GPS data shall deviate by no more than 4 % from the reference. If the GPS data do not meet these requirements and no other reliable speed source is available, the test results shall be voided.

9.2.   Calculating NMHC and CH4 concentrations

For methane measurement using a NMC-FID, the calculation of NMHC depends on the calibration gas/method used for the zero/span calibration adjustment. When a FID is used for THC measurement without a NMC, it shall be calibrated with propane/air or propane/N2 in the normal manner. For the calibration of the FID in series with a NMC, the following methods are permitted:

The density used for calculating the NMHC mass shall be equal to that of total hydrocarbons at 273,15 K and 101,325 kPa and is fuel-dependent.

    INTRODUCTION

The Moving Averaging Window method provides an insight on the real-driving emissions (RDE) occurring during the test at a given scale. The test is divided in sub-sections (windows) and the subsequent statistical treatment aims at identifying which windows are suitable to assess the vehicle RDE performance.

The ‘normality’ of the windows is conducted by comparing their CO2 distance-specific emissions (1) with a reference curve. The test is complete when the test includes a sufficient number of normal windows, covering different speed areas (urban, rural, motorway).

    MOVING AVERAGING WINDOWS

3.1.   Definition of averaging windows

The instantaneous emissions calculated according to Appendix 4 shall be integrated using a moving averaging window method, based on the reference CO2 mass. The principle of the calculation is as follows: The mass emissions are not calculated for the complete data set, but for sub-sets of the complete data set, the length of these sub-sets being determined so as to match the CO2 mass emitted by the vehicle over the reference laboratory cycle. The moving average calculations are conducted with a time increment Δt corresponding to the data sampling frequency. These sub-sets used to average the emissions data are referred to as ‘averaging windows’. The calculation described in the present point may be run from the last point (backwards) or from the first point (forward).

The following data shall not be considered for the calculation of the CO2 mass, the emissions and the distance of the averaging windows:

 

The periodic verification of the instruments and/or after the zero drift verifications;

 

The cold start emissions, defined according to Appendix 4, point 4.4;

 

Vehicle ground speed < 1 km/h;

 

Any section of the test during which the combustion engine is switched off.

The mass (or particle number) emissions Mgas,j shall be determined by integrating the instantaneous emissions in g/s (or #/s for PN) calculated as specified in Appendix 4.

    EVALUATION OF WINDOWS

4.1.   Introduction

The reference dynamic conditions of the test vehicle are set out from the vehicle CO2 emissions versus average speed measured at type approval and referred to as ‘vehicle CO2 characteristic curve’.

To obtain the distance-specific CO2 emissions, the vehicle shall be tested on the chassis dynamometer by applying the vehicle road load settings as determined following the procedure prescribed in Annex 4 of the UNECE Global Technical Regulation No. 15 - Worldwide harmonized Light vehicles Test Procedure (ECE/TRANS/180/Add.15). The road loads shall not account for the mass added to the vehicle during the RDE test, e.g. the co-pilot and the PEMS equipment.

4.2.5.   

Formula

(average speed of the Extra High Speed phase of the WLTP cycle)

Formula = Vehicle CO2 emissions over the Extra High Speed phase of the WLTP cycle x 1,05 [g/km]

4.3.   CO2 characteristic curve definition

Using the reference points defined in section 4.2, the characteristic curve CO2 emissions are calculated as a function of the average speed using two linear sections (P 1, P 2) and (P 2, P 3). The section (P 2, P 3) is limited to 145 km/h on the vehicle speed axis. The characteristic curve is defined by equations as follows:

In this numerical example, the trip consists of 7 036 averaging windows. Table 5 lists the number of windows classified in urban, rural and motorway according to their average vehicle speed and divided in regions with respect to their distance to the CO2 characteristic curve. The trip is complete since it comprises at least 15 % of urban, rural and motorway windows out of the total number of windows. In addition the trip is characterized as normal since at least 50 % of the urban, rural and motorway windows are within the primary tolerances defined for the characteristic curve.

    EVALUATION OF THE MEASURED EMISSIONS USING A STANDARDISED WHEEL POWER FREQUENCY DISTRIBUTION

The power binning method uses the instantaneous emissions of the pollutants, mgas, i (g/s) calculated in accordance with Appendix 4.

The mgas, i values shall be classified in accordance with the corresponding power at the wheels and the classified average emissions per power class shall be weighted to obtain the emission values for a test with a normal power distribution according to the following points.

3.1.   Sources for the actual wheel power

The actual wheel power Pr,i shall be the total power to overcome air resistance, rolling resistance, road gradients, longitudinal inertia of the vehicle and rotational inertia of the wheels.

When measured and recorded, the wheel power signal shall use a torque signal meeting the linearity requirements laid down in Appendix 2, point 3.2. The reference point for measurement are the wheel hubs of the driven wheels.

As an alternative, the actual wheel power may be determined from the instantaneous CO2 emissions following the procedure laid down in point 4 of this Appendix.

3.2.   Calculation of the moving averages of the instantaneous test data

Three second moving averages shall be calculated from all relevant instantaneous test data to reduce influences of possibly imperfect time alignment between emission mass flow and wheel power. The moving average values shall be computed in a 1 Hz frequency:

3.3.   Classification of the moving averages to urban, rural and motorway

The standard power frequencies are defined for urban driving and for the total trip (see paragraph 3.4) and a separate evaluation of the emissions shall be made for the total trip and for the urban part. For the later evaluation of the urban part of the trip, the three second moving averages calculated according to paragraph 3.2 shall be allocated to urban driving conditions according to the three second moving average of the velocity signal (v3s,k) following the speed range defined in Table 1-1. The sample for the total trip evaluation shall cover all speed ranges including also the urban part.

3.5.   Classification of the moving average values

The cold start emissions, defined according to Appendix 4, point 4.4, shall be excluded from the following evaluation.

Each moving average value calculated according to point 3.2 shall be sorted into the de-normalized wheel power class into which the actual 3 second moving average wheel power Pw,3s,k fits. The de-normalised wheel power class limits have to be calculated according to point 3.3.

The classification shall be done for all three second moving averages of the entire valid trip data including also all urban trip parts. Additionally all moving averages classified to urban according to the velocity limits defined in table 1-1 shall be classified into one set of urban power classes independently of the time when the moving average appeared in the trip.

Then the average of all three second moving average values within a wheel power class shall be calculated for each wheel power class per parameter. The equations are described below and shall be applied once for the urban data set and once for the total data set.

    ASSESSMENT OF THE WHEEL POWER FROM THE INSTANTANEOUS CO2 MASS FLOW

The power at the wheels (Pw,i) can be computed from the measured CO2 mass flow in 1 Hz. For this calculation the vehicle specific CO2 line (‘Veline’) shall be used.

The Veline shall be calculated from the vehicle type approval test in the WLTC according to the test procedure described in UNECE Global Technical Regulation No. 15 - Worldwide harmonized Light vehicles Test Procedure (ECE/TRANS/180/Add.15).

3.1.2.

A single vehicle manufacturer.

3.2.   Technical criteria

3.2.1.   Propulsion type (e.g. ICE, HEV, PHEV)

3.2.2.   Type(s) of fuel(s) (e.g. petrol, diesel, LPG, NG, …). Bi- or flex-fuelled vehicles may be grouped with other vehicles, with which they have one of the fuels in common.

3.2.3.   Combustion process (e.g. two stroke, four stroke)

3.2.4.   Number of cylinders

3.2.5.   Configuration of the cylinder block (e.g. in-line, V, radial, horizontally opposed)

3.2.6.   Engine volume

The vehicle manufacturer shall specify a value V_eng_max (= maximum engine volume of all vehicles within the PEMS test family). The engine volumes of vehicles in the PEMS test family shall not deviate more than – 22 % from V_eng_max if V_eng_max ≥ 1 500 ccm and – 32 % from V_eng_max if V_eng_max < 1 500 ccm.

3.2.11.   Exhaust gas recirculation (with or without, internal/external, cooled/non-cooled, low/high pressure)

3.3.   Extension of a PEMS test family

An existing PEMS test family may be extended by adding new vehicle emission types to it. The extended PEMS test family and its validation must also fulfil the requirements of points 3 and 4. This may in particular require the PEMS testing of additional vehicles to validate the extended PEMS test family according to point 4.

3.4.   Alternative PEMS test family

As an alternative to the provisions of points 3.1 to 3.2 the vehicle manufacturer may define a PEMS test family, which is identical to a single vehicle emission type. In this the requirement of point 4.1.2 for validating the PEMS test family shall not apply.

  • 4. 
    VALIDATION OF A PEMS TEST FAMILY

4.1.   General requirements for validating a PEMS test family

 
 

4.1.1.

The vehicle manufacturer presents a representative vehicle of the PEMS test family to the authority. The vehicle shall be subject to a PEMS test carried out by a Technical Service to demonstrate compliance of the representative vehicle with the requirements of this Annex.

 
 

4.1.2.

The authority selects additional vehicles according to the requirements of point 4.2 of this Appendix for PEMS testing carried out by a Technical Service to demonstrate compliance of the selected vehicles with the requirements of this Annex. The technical criteria for selection of an additional vehicle according to point 4.2 of this Appendix. shall be recorded with the test results.

 
 

4.1.3.

With agreement of the authority, a PEMS test can also be driven by a different operator witnessed by a Technical Service, provided that at least the tests of the vehicles required by points 4.2.2 and 4.2.6 of this Appendix and in total at least 50 % of the PEMS tests required by this Appendix for validating the PEMS test family are driven by a Technical Service. In such case the Technical Service remains responsible for the proper execution of all PEMS tests pursuant to the requirements of this Annex.

 
 

4.1.4.

A PEMS test results of a specific vehicle may be used for validating different PEMS test families according to the requirements of this Appendix under the following conditions:

 

the vehicles included in all PEMS test families to be validated are approved by a single authority according to the requirements of Regulation (EC) 715/2007 and this authority agrees to the use of the specific vehicle's PEMS test results for validating different PEMS test families;

 

each PEMS test family to be validated includes a vehicle emission type, which comprises the specific vehicle;

For each validation the applicable responsibilities are considered to be borne by the manufacturer of the vehicles in the respective family, regardless of whether this manufacturer was involved in the PEMS test of the specific vehicle emission type.

4.2.   Selection of vehicles for PEMS testing when validating a PEMS test family

By selecting vehicles from a PEMS test family it should be ensured that the following technical characteristics relevant for pollutant emissions are covered by a PEMS test. One vehicle selected for testing can be representative for different technical characteristics. For the validation of a PEMS test family vehicles shall be selected for PEMS testing as follows:

 

4.2.1.

For each combination of fuels (e.g. petrol-LPG, petrol-NG, petrol only), on which some vehicle of the PEMS test family can operate, at least one vehicle that can operate on this combination of fuels shall be selected for PEMS testing.

 

4.2.2.

The manufacturer shall specify a value PMRH (= highest power-to-mass-ratio of all vehicles in the PEMS test family) and a value PMRL (= lowest power-to-mass-ratio of all vehicles in the PEMS test family). Here the ‘power-to-mass-ratio’ corresponds to the ratio of the maximum net power of the internal combustion engine as indicated in point 3.2.1.8 of Appendix 3 to Annex I of this Regulation and of the reference mass as defined in Article 3(3) of Regulation (EC) No 715/2007. At least one vehicle configuration representative for the specified PMRH and one vehicle configuration representative for the specified PMRL of a PEMS test family shall be selected for testing. If the power-to-mass ratio of a vehicle deviates by not more than 5 % from the specified value for PMRH, or PMRL, the vehicle should be considered as representative for this value.

 

4.2.3.

At least one vehicle for each transmission type (e.g., manual, automatic, DCT) installed in vehicles of the PEMS test family shall be selected for testing.

 

4.2.4.

    TRIP INDICATORS

3.1.   Calculations

3.1.1.   Data pre-processing

Dynamic parameters like acceleration, Formula or RPA shall be determined with a speed signal of an accuracy of 0,1 % for all speed values above 3 km/h and a sampling frequency of 1 Hz. This accuracy requirement is generally fulfilled by signals obtained from a wheel (rotational) speed sensor.

The speed trace shall be checked for faulty or implausible sections. The vehicle speed trace of such sections is characterised by steps, jumps, terraced speed traces or missing values. Short faulty sections shall be corrected, for example by data interpolation or benchmarking against a secondary speed signal. Alternatively, short trips containing faulty sections could be excluded from the subsequent data analysis. In a second step the acceleration values shall be calculated and ranked in ascending order, as to determine the acceleration resolution Formula.

If Formula, the vehicle speed measurement is sufficiently accurate.

If Formula, data smoothing by using a T4253H Hanning filter shall be performed

The T4235 Hanning filter performs the following calculations: The smoother starts with a running median of 4, which is centred by a running median of 2. The filter then re-smoothes these values by applying a running median of 5, a running median of 3, and hanning (running weighted averages). Residuals are computed by subtracting the smoothed series from the original series. This whole process is then repeated on the computed residuals. Finally, the smoothed final speed values are computed by summing up the smoothed values obtained the first time through the process with the computed residuals.

The correct speed trace builds the basis for further calculations and binning as described in paragraph 8.1.2.

3.1.2.   Calculation of distance, acceleration and Formula

The following calculations shall be performed over the whole time based speed trace (1 Hz resolution) from second 1 to second tt (last second).

The distance increment per data sample shall be calculated as follows:

Formula

where:

 

di

is the distance covered in time step i [m]

ν i

is the actual vehicle speed in time step i [km/h]

N t

is the total number of samples

The acceleration shall be calculated as follows:

Formula

where:

 

ai

is the acceleration in time step i [m/s2]. For i = 1: Formula, for Formula: Formula.

The product of vehicle speed per acceleration shall be calculated as follows:

Formula

where:

 

Formula

is the product of the actual vehicle speed per acceleration in time step i [m2/s3 or W/kg].

3.1.3.   Binning of the results

After the calculation of ai and Formula, the values vi , di , ai and Formula shall be ranked in ascending order of the vehicle speed.

All datasets with Formula belong to the ‘urban’ speed bin, all datasets with Formula belong to the ‘rural’ speed bin and all datasets with Formula belong to the ‘motorway’ speed bin.

The number of datasets with acceleration values Formula shall be bigger or equal to 150 in each speed bin.

For each speed bin the average vehicle speed Formula shall be calculated as follows:

Formula

where:

 

Nk

is the total number of samples of the urban, rural, and motorway shares.

3.1.4.   Calculation of Formula per speed bin

The 95th percentile of the Formula values shall be calculated as follows:

The Formula values in each speed bin shall be ranked in ascending order for all datasets with Formula Formula and the total number of these samples Mk shall be determined.

Percentile values are then assigned to the Formula values with Formula as follows:

The lowest Formula value gets the percentile 1/Mk , the second lowest 2/Mk , the third lowest 3/Mk and the highest value Formula

Formula is the Formula value, with Formula If Formula cannot be met, Formula shall be calculated by linear interpolation between consecutive samples j and j+1 with Formula and Formula.

The relative positive acceleration per speed bin shall be calculated as follows:

Formula

where:

 

RPAk

is the relative positive acceleration for urban, rural and motorway shares in [m/s2 or kWs/(kg*km)]

Δt

is a time difference equal to 1 second

4.1.   General

The cumulative positive elevation gain of a RDE trip shall be calculated as a three-step procedure, consisting of (i) the screening and principle verification of data quality, (ii) the correction of instantaneous vehicle altitude data, and (iii) the calculation of the cumulative positive elevation gain.

4.2.   Screening and principle verification of data quality

The instantaneous vehicle speed data shall be checked for completeness. Correcting for missing data is permitted if gaps remain within the requirements specified in Point 7 of Appendix 4; else, the test results shall be voided. The instantaneous altitude data shall be checked for completeness. Data gaps shall be completed by data interpolation. The correctness of interpolated data shall be verified by a topographic map. It is recommended to correct interpolated data if the following condition applies:

4.4.   Final calculation of the cumulative positive elevation gain

4.4.1.   Establishment of a uniform spatial resolution

Where:

4.4.3.   Calculation of the final result

The positive cumulative elevation gain of a trip shall be calculated by integrating all positive interpolated and smoothed road grades, i.e. roadgrade,2(d). The result should be normalized by the total test distance d tot and expressed in meters of cumulative elevation gain per one hundred kilometers of distance.

  • 5. 
    NUMERICAL EXAMPLE

Tables 1 and 2 show how to calculate the positive elevation gain on the basis of data recorded during an on-road test performed with PEMS. For the sake of brevity an extract of 800m and 160s is presented here.

5.1.   Screening and principle verification of data quality

The screening and principle verification of data quality consists of two steps. First, the completeness of vehicle speed data is checked. No data gaps related to vehicle speed are detected in the present data sample (see Table 1). Second, the altitude data are checked for completeness; in the data sample, altitude data related to seconds 2 and 3 are missing. The gaps are filled by interpolating the GPS signal. In addition, the GPS altitude is verified by a topographic map; this verification includes the altitude h(0) at the start of the trip. Altitude data related to seconds 112 -114 are corrected on the basis of the topographic map to satisfy the following condition:

Formula

As result of the applied data verification, the data in the fifth column h(t) are obtained.

5.2.   Correction of instantaneous vehicle altitude data

As a next step, the altitude data h(t) of seconds 1 to 4, 111 to 112 and 159 to 160 are corrected assuming the altitude values of seconds 0, 110 and 158 respectively since for the altitude data in these time periods the following condition applies:

Formula

As result of the applied data correction, the data in the sixth column hcorr(t) are obtained. The effect of the applied verification and correction steps on the altitude data is depicted in Figure 2.

5.3.   Calculation of the cumulative positive elevation gain

5.3.1.   Establishment of a uniform spatial resolution

The instantaneous distance di is calculated by dividing the instantaneous vehicle speed measured in km/h by 3.6 (Column 7 in Table 1). Recalculating the altitude data to obtain a uniform spatial resolution of 1 m yields the discrete way points d (Column 1 in Table 2) and their corresponding altitude values hint(d) (Column 7 in Table 2). The altitude of each discrete way point d is calculated through interpolation of the measured instantaneous altitude hcorr as:

Formula

Formula

5.3.2.   Additional data smoothing

In Table 2, the first and last discrete way points are: d a=0m and d e=799m, respectively. The altitude data of each discrete way point is smoothed by applying a two steps procedure. The first smoothing run consists of:

Formula

chosen to demonstrate the smoothing for d ≤ 200m

Formula

chosen to demonstrate the smoothing for 200m < d < (599m)

Formula

chosen to demonstrate the smoothing for d ≥ (599m)

The smoothed and interpolated altitude is calculated as:

Formula

Formula

Second smoothing run:

Formula

chosen to demonstrate the smoothing for d ≤ 200m

Formula

chosen to demonstrate the smoothing for 200m < d < (599)

Formula

chosen to demonstrate the smoothing for d ≥ (599m)

5.3.3.   Calculation of the final result

The positive cumulative elevation gain of a trip is calculated by integrating all positive interpolated and smoothed road grades, i.e. values in the column roadgrade,2(d) in Table 2. For the entire data set the total covered distance was Formula and all positive interpolated and smoothed road grades were of 516m. Therefore the positive cumulative elevation gain reached 516*100/139,7=370m/100km.

The data exchange file shall be structured as follows: The first 195 lines shall be reserved for a header that provides specific information about, e.g., the test conditions, the identity and calibration of the PEMS equipment (Table 1). Lines 198-200 shall contain the labels and units of parameters. Lines 201 and all consecutive data lines shall comprise the body of the data exchange file and report parameter values (Table 2). The body of the data exchange file shall contain at least as many data lines as the test duration in seconds multiplied by the recording frequency in hertz.

3.3.   Intermediate and final results

Summary parameters of intermediate results shall be recorded and structured as indicated in Table 3. The information in Table 3 shall be obtained prior to the application of the data evaluation methods laid down in Appendices 5 and 6.

The vehicle manufacturer shall record the results of the two data evaluation methods in separate files. The results of the data evaluation with the method described in Appendix 5 shall be reported according to Tables 4, 5 and 6. The results of the data evaluation with the method described in Appendix 6 shall be reported according to Tables 7, 8 and 9. The header of the data reporting file shall be composed of three parts. The first 95 lines shall be reserved for specific information about the settings of the data evaluation method. Lines 101-195 shall report the results of the data evaluation method. Lines 201-490 shall be reserved for reporting the final emission results. Line 501 and all consecutive data lines comprise the body of the data reporting file and shall contain the detailed results of the data evaluation.

5.1.1.   Temperature conditioning test

In a dedicated temperature chamber, the canister(s) is (are) cycled between temperatures from – 15 °C to 60 °C, with 30 min of stabilisation at – 15 °C and 60 °C. Each cycle shall last 210 min as in Figure 3. The temperature gradient shall be as close as possible to 1 °C/min. No forced air flow should pass through the canister(s).

The cycle is repeated 50 times consecutively. In total, this operation will last 175 hours.

Figure VI.3

Temperature conditioning cycle

Image

5.1.2.   Canister vibration conditioning test

After the temperature aging procedure, the canister(s) is (are) shaken along the vertical axis with the canister(s) mounted as per its orientation in the vehicle with overall Grms (1) > 1.5m/sec2 with frequency of 30 ± 10 Hz. The test shall last 12 hours.

5.1.3.   Canister Fuel aging test

5.1.3.1.   Fuel Aging for 300 cycles

 
 

5.1.3.1.1.

After the temperature conditioning test and vibration test, the canister(s) is aged with a mixture of Type 1 E10 market fuel as specified in point 5.1.3.1.1.1 below and nitrogen or air with a 50 ± 15 percent fuel vapour volume. The fuel vapour fill rate must be kept between 60 ± 20 g/h.

The canister(s) is (are) loaded to the corresponding breakthrough. Breakthrough shall be considered as the point at which the cumulative quantity of hydrocarbons emitted is equal to 2 grams. As an alternative, the loading is deemed completed when the equivalent concentration level at the vent hole reaches 3 000 ppm.

 
 

5.1.3.1.1.1

The E10 market fuel used for this test shall fulfil the same requirements as an E10 reference fuel for the following points:

Density at 15 °C

 

Vapour Pressure (DVPE)

 

Distillation (evaporates only)

 

Hydrocarbon analysis (olefins, aromatics, benzene only)

 

Oxygen content

 

Ethanol content

 
 

5.1.3.1.2.

The canister(s) shall be purged according the procedure of paragraph 5.1.3.8. of Annex 7 to UN/ECE Regulation No 83.

The canister must be purged between 5 minutes to 1 hour maximum after loading.

 
 

5.1.3.1.3.

The steps of the procedure set out in points 5.1.3.1.1. and 5.1.3.1.2. shall be repeated 50 times, followed by a measurement of the Butane Working Capacity (BWC), meant as the ability of an activated carbon canister to absorb and desorb butane from dry air under specified conditions, in 5 butane cycles, as described in point 5.1.3.1.4 below. The fuel vapour ageing will continue until 300 cycles are reached. A measurement of the BWC in 5 butane cycles, as set out in point 5.1.3.1.4, will be made after the 300 cycles.

 
 

5.1.3.1.4.

After 50 and 300 Fuel aging cycles, a measurement of BWC is performed. This measurement consists of loading the canister according to paragraph 5.1.6.3., of Annex 7 to UN/ECE Regulation No 83 until breakthrough. The BWC is recorded.

Then, the canister(s) shall be purged according the procedure of paragraph 5.1.3.8. of Annex 7 to UN/ECE Regulation No 83.

The canister must be purged between 5 minutes to 1 hour maximum after loading.

The operation of butane loading is repeated 5 times. The BWC is recorded after each butane loading step. The BWC50 is calculated as the average of the 5 BWC and recorded.

In total, the canister(s) will be aged with 300 fuel aging cycles + 10 butane cycles and considered to be stabilized.

5.1.3.2.   If the canister(s) is (are) provided by the Suppliers, the Manufacturers shall inform in advance the Type Approval Authorities to allow them to witness any part of the aging in the Supplier’s facilities.

5.1.3.3.   The manufacturer shall provide to the Type Approval Authorities a test report including at least the following elements:

    IN-USE PERFORMANCE

3.1.   General Requirements

The technical requirements and specifications shall be those set out in Appendix 1 to Annex 11 to UN/ECE Regulation No 83 with the exceptions and additional requirements as described in the following sections.

 
 

3.1.1.

The requirements of paragraph 7.1.5 of Appendix 1 to Annex 11 to UN/ECE Regulation No 83 shall be understood as being as follows.

For new type approvals and new vehicles the monitor required by point 2.9 of this Annex shall have an IUPR greater or equal to 0,1 until three years after the dates specified in Article 10(4) and (5) of Regulation (EC) No 715/2007 respectively.

 
 

3.1.2.

The requirements of paragraph 7.1.7 of Appendix 1 to Annex 11 to UN/ECE Regulation No 83 shall be understood as being as follows.

The manufacturer shall demonstrate to the approval authority and, upon request, to the Commission that these statistical conditions are satisfied for all monitors required to be reported by the OBD system according to paragraph 7.6. of Appendix 1 to Annex 11 to Regulation No 83 not later than 18 months after the entry onto the market of the first vehicle type with IUPR in an OBD family and every 18 months thereafter. For this purpose, for OBD families consisting of more than 1000 registrations in the Union, that are subject to sampling within the sampling period, the process described in Annex II shall be used without prejudice to the provisions of paragraph 7.1.9. of Appendix 1 to Annex 11 to Regulation No 83.

In addition to the requirements set out in Annex II and regardless of the result of the audit described in Section 2 of Annex II, the authority granting the approval shall apply the in-service conformity check for IUPR described in Appendix 1 to Annex II in an appropriate number of randomly determined cases. ‘In an appropriate number of randomly determined cases’ means, that this measure has a dissuasive effect on non-compliance with the requirements of Section 3 of this Annex or the provision of manipulated, false or non-representative data for the audit. If no special circumstances apply and can be demonstrated by the type-approval authorities, random application of the in-service conformity check to 5 % of the type approved OBD families shall be considered as sufficient for compliance with this requirement. For this purpose, type-approval authorities may find arrangements with the manufacturer for the reduction of double testing of a given OBD family as long as these arrangements do not harm the dissuasive effect of the type-approval authority’s own in-service conformity check on non-compliance with the requirements of Section 3 of this Annex. Data collected by Member States during surveillance testing programmes may be used for in-service conformity checks. Upon request, type-approval authorities shall provide data on the audits and random in-service conformity checks performed, including the methodology used for identifying those cases, which are made subject to the random in-service conformity check, to the Commission and other type-approval authorities.

 
 

3.1.3.

Non-compliance with the requirements of paragraph 7.1.6. of Appendix 1 to Annex 11 to Regulation No 83 established by tests described in point 3.1.2 of this Appendix or paragraph 7.1.9 of Appendix 1 to Annex 11 to Regulation No 83 shall be considered as an infringement subject to the penalties set out in Article 13 of Regulation (EC) No 715/2007. This reference does not limit the application of such penalties to other infringements of other provisions of Regulation (EC) No 715/2007 or this Regulation, which do not explicitly refer to Article 13 of Regulation (EC) No 715/2007.

 
 

3.1.4.

Paragraph 7.6.1. of Appendix 1 to Annex 11 of UN/ECE Regulation No 83 shall be replaced with the following:

 

‘7.6.1.

The OBD system shall report, in accordance with the standard listed in paragraph 6.5.3.2.(a) of this Appendix, the ignition cycle counter and general denominator as well as separate numerators and denominators for the following monitors, if their presence on the vehicle is required by this annex:

 

(a)

Catalysts (each bank to be reported separately);

 

(b)

Oxygen/exhaust gas sensors, including secondary oxygen sensors

(each sensor to be reported separately);

 

(c)

Evaporative system;

 

(d)

EGR system;

 

(e)

VVT system;

 

(f)

Secondary air system;

 

(g)

Particulate filter;

 

(h)

NOx after-treatment system (e.g. NOx absorber, NOx reagent/catalyst system);

 

(i)

Boost pressure control system.’

Paragraph 7.6.2. of Appendix 1 to Annex 11 of UN/ECE Regulation No 83 shall be replaced with the following:

 

‘7.6.2.

For specific components or systems that have multiple monitors, which are required to be reported by this point (e.g. oxygen sensor bank 1 may have multiple monitors for sensor response or other sensor characteristics), the OBD system shall separately track numerators and denominators for each of the specific monitors and report only the corresponding numerator and denominator for the specific monitor that has the lowest numerical ratio. If two or more specific monitors have identical ratios, the corresponding numerator and denominator for the specific monitor that has the highest denominator shall be reported for the specific component.’

A new paragraph 7.6.2.1. of Appendix 1 to Annex 11 of UN/ECE Regulation No 83 shall be inserted as follows:

 

‘7.6.2.1.

Numerators and denominators for specific monitors of components or systems, that are monitoring continuously for short circuit or open circuit failures are exempted from reporting.

“Continuously,” if used in this context means monitoring is always enabled and sampling of the signal used for monitoring occurs at a rate no less than two samples per second and the presence or the absence of the failure relevant to that monitor has to be concluded within 15 seconds.

If for control purposes, a computer input component is sampled less frequently, the signal of the component may instead be evaluated each time sampling occurs.

It is not required to activate an output component/system for the sole purpose of monitoring that output component/system.’

Annex IX of Directive 2007/46/EC is hereby replaced by the following text:

‘ANNEX IX

EC CERTIFICATE OF CONFORMITY

  • 0. 
    OBJECTIVES

The certificate of conformity is a statement delivered by the vehicle manufacturer to the buyer in order to assure him that the vehicle he has acquired complies with the legislation in force in the European Union at the time it was produced.

The certificate of conformity also serves the purpose to enable the competent authorities of the Member States to register vehicles without having to require the applicant to supply additional technical documentation.

For these purposes, the certificate of conformity has to include:

 

(a)

the Vehicle Identification Number;

 

(b)

the exact technical characteristics of the vehicle (i.e. it is not permitted to mention any range of value in the various entries).

  • 1. 
    GENERAL DESCRIPTION
 
 

1.1.

The certificate of conformity shall consist of two parts.

 

(a)

SIDE 1, which consists of a statement of compliance by the manufacturer. The same template is common to all vehicle categories.

 

(b)

SIDE 2, which is a technical description of the main characteristics of the vehicle. The template of side 2 is adapted to each specific vehicle category.

 
 

1.2.

The certificate of conformity shall be established in a maximum format A4 (210 × 297 mm) or a folder of maximum format A4.

 
 

1.3.

Without prejudice to the provisions in Section O(b), the values and units indicated in the second part shall be those given in the type-approval documentation of the relevant regulatory acts. In case of conformity of production checks the values shall be verified according to the methods laid down in the relevant regulatory acts. The tolerances allowed in those regulatory acts shall be taken into account.

  • 2. 
    SPECIAL PROVISIONS
 
 

2.1.

Model A of the certificate of conformity (complete vehicle) shall cover vehicles which can be used on the road without requiring any further stage for their approval.

 
 

2.2.

Model B of the certificate of conformity (completed vehicles) shall cover vehicles which have undergone a further stage for their approval.

This is the normal result of the multi-stage approval process (e.g. a bus built by a second stage manufacturer on a chassis built by a vehicle manufacturer).

The additional features added during the multi-stage process shall be described briefly.

 
 

2.3.

Model C of the certificate of conformity (incomplete vehicles) shall cover vehicles which need a further stage for their approval (e.g. truck chassis).

Except for tractors for semi-trailers, certificates of conformity covering chassis-cab vehicles belonging to category N shall be of Model C.

    Cycle modification

Paragraph 8. of this Sub-Annex shall not apply to OVC-HEVs, NOVC-HEVs and NOVC-FCHVs.

8.1.   General remarks

The cycle to be driven shall depend on the test vehicle’s rated power to mass in running order ratio, W/kg, and its maximum velocity, vmax, km/h.

Driveability problems may occur for vehicles with power to mass ratios close to the borderlines between Class 1 and Class 2, Class 2 and Class 3 vehicles, or very low powered vehicles in Class 1.

Since these problems are related mainly to cycle phases with a combination of high vehicle speed and high accelerations rather than to the maximum speed of the cycle, the downscaling procedure shall be applied to improve driveability.

8.2.   This paragraph describes the method to modify the cycle profile using the downscaling procedure.

8.2.1.   Downscaling procedure for Class 1 vehicles

Figure A1/14 shows a downscaled medium speed phase of the Class 1 WLTC as an example.

Figure A1/14

Downscaled medium speed phase of the class 1 WLTC

WLTC class 1, phase medium 1

v_downscale

For the Class 1 cycle, the downscaling period is the time period between second 651 and second 906. Within this time period, the acceleration for the original cycle shall be calculated using the following equation:

Formula

where:

 

vi

is the vehicle speed, km/h;

i

is the time between second 651 and second 906.

The downscaling shall be applied first in the time period between second 651 and second 848. The downscaled speed trace shall be subsequently calculated using the following equation:

Formula

with i = 651 to 847.

For i = 651, Formula

In order to meet the original vehicle speed at second 907, a correction factor for the deceleration shall be calculated using the following equation:

Formula

where 36,7 km/h is the original vehicle speed at second 907.

The downscaled vehicle speed between second 849 and second 906 shall be subsequently calculated using the following equation:

Formula

for i = 849 to 906.

8.2.2.   Downscaling procedure for Class 2 vehicles

Since the driveability problems are exclusively related to the extra high speed phases of the Class 2 and Class 3 cycles, the downscaling is related to those paragraphs of the extra high speed phases where the driveability problems occur (see Figure A1/15).

Figure A1/15

Downscaled extra high speed phase of the class 2 WLTC

WLTC class 2, phase extra high 2

v_downscale

For the Class 2 cycle, the downscaling period is the time period between second 1520 and second 1742. Within this time period, the acceleration for the original cycle shall be calculated using the following equation:

Formula

where:

 

vi

is the vehicle speed, km/h;

i

is the time between second 1520 and second 1742.

The downscaling shall be applied first to the time period between second 1520 and second 1725. Second 1725 is the time when the maximum speed of the extra high speed phase is reached. The downscaled speed trace shall be subsequently calculated using the following equation:

Formula

for i = 1520 to 1724.

For i = 1520, Formula

In order to meet the original vehicle speed at second 1743, a correction factor for the deceleration shall be calculated using the following equation:

Formula

90,4 km/h is the original vehicle speed at second 1743.

The downscaled vehicle speed between second 1726 and second 1742 shall be calculated using the following equation:

Formula

for i = 1726 to 1742.

8.2.3.   Downscaling procedure for Class 3 vehicles

Figure A1/16 shows a downscaled extra high speed phase of the Class 3 WLTC as an example.

v_downscale

For the Class 3 cycle, the downscaling period is the time period between second 1533 and second 1762. Within this time period, the acceleration for the original cycle shall be calculated using the following equation:

Formula

where:

 

vi

is the vehicle speed, km/h;

i

is the time between second 1533 and second 1762.

The downscaling shall be applied first in the time period between second 1533 and second 1724. Second 1724 is the time when the maximum speed of the extra high speed phase is reached. The downscaled speed trace shall be subsequently calculated using the following equation:

Formula

for i = 1533 to 1723.

For i = 1533, Formula

In order to meet the original vehicle speed at second 1763, a correction factor for the deceleration shall be calculated using the following equation:

Formula

82.6 km/h is the original vehicle speed at second 1763.

The downscaled vehicle speed between second 1725 and second 1762 shall be subsequently calculated using the following equation:

Formula

for i = 1725 to 1762.

8.3.   Determination of the downscaling factor

The downscaling factor fdsc, is a function of the ratio rmax between the maximum required power of the cycle phases where the downscaling is to be applied and the rated power of the vehicle, Prated.

The maximum required power Preq,max,i (in kW) is related to a specific time i and the corresponding vehicle speed vi in the cycle trace and is calculated using the following equation:

Formula

where:

 

f0, f1, f2

are the applicable road load coefficients, N, N/(km/h), and N/(km/h)2 respectively;

TM

is the applicable test mass, kg;

vi

is the speed at time i, km/h.

The cycle time i at which maximum power or power values close to maximum power is required, is: second 764 for Class 1, second 1574 for Class 2 and second 1566 for Class 3 vehicles.

The corresponding vehicle speed values, vi, and acceleration values, ai, are as follows:

 
 

vi = 61,4 km/h, ai = 0,22 m/s2 for Class 1,

 
 

vi = 109,9 km/h, ai = 0,36 m/s2 for Class 2,

 
 

vi = 111,9 km/h, ai = 0,50 m/s2 for Class 3.

rmax shall be calculated using the following equation:

Formula

The downscaling factor, fdsc, shall be calculated using the following equations:

if Formula, then Formula

and no downscaling shall be applied.

If Formula, then Formula

The calculation parameter/coefficients, r0, a1 and b1, are as follows:

 
 

Class 1 r0 = 0,978, a1 = 0,680, b1 = – 0,665

 
 

Class 2 r0 = 0,866, a1 = 0,606, b1 = – 0,525.

 
 

Class 3 r0 = 0,867, a1 = 0,588 b1 = – 0,510.

The resulting fdsc is mathematically rounded to 3 places of decimal and is applied only if it exceeds 0,010.

The following data shall be included in all relevant test reports:

 

(a)

fdsc;

 

(b)

vmax;

 

(c)

distance driven, m.

The distance shall be calculated as the sum of vi in km/h divided by 3,6 over the whole cycle trace.

8.4.   Additional requirements

For different vehicle configurations in terms of test mass and driving resistance coefficients, downscaling shall be applied individually.

If, after the application of downscaling the vehicle maximum speed is lower than the maximum speed of the cycle, the process described in paragraph 9. of this Sub-Annex shall be applied with the applicable cycle.

If the vehicle cannot follow the speed trace of the applicable cycle within the tolerance at speeds lower than its maximum speed, it shall be driven with the accelerator control fully activated during these periods. During such periods of operation, speed trace violations shall be permitted.

  • 9. 
    Cycle modifications for vehicles with a maximum speed lower than the maximum speed of the cycle specified in the previous paragraphs of this Sub-Annex

9.1.   General remarks

This paragraph applies to vehicles that are technically able to follow the speed trace of the cycle specified in paragraph 1. of this Sub-Annex (base cycle or downscaled base cycle) at speeds lower than their maximum speed, but whose maximum speed is lower than the maximum speed of the cycle. The maximum speed of such a vehicle shall be referred to as its capped speed vcap. The maximum speed of the base cycle shall be referred to as vmax,cycle.

In such cases the base cycle shall be modified as described in paragraph 9.2. in order to achieve the same cycle distance for the capped speed cycle as for the base cycle.

9.2.   Calculation steps

9.2.1.   Determination of the distance difference per cycle phase

An interim capped speed cycle shall be derived by replacing all vehicle speed samples vi where vi > vcap by vcap.

 
 

9.2.1.1.

If vcap < vmax,medium, the distances of the medium speed phases of the base cycle dbase,medium and the interim capped speed cycle dcap,medium shall be calculated using the following equation for both cycles:

Formula

where:

 

vmax,medium

is the maximum vehicle speed of the medium speed phase as listed in Table A1/2 for class 1 vehicles, in Table A1/4 for class 2 vehicles, in Table A1/8 for class 3a vehicles and in Table A1/9 for class 3b vehicles.

 
 

9.2.1.2.

If vcap < vmax,high, the distances of the high speed phases of the base cycle dbase,high and the interim capped speed cycle dcap,high shall be calculated using the following equation for both cycles:

Formula

 

vmax,high

is the maximum vehicle speed of the high speed phase as listed in Table A1/5 for Class 2 vehicles, in Table A1/10 for Class 3a vehicles and in Table A1/11 for Class 3b vehicles.

 
 

9.2.1.3.

The distances of the extra high speed phase of the base cycle dbase,exhigh and the interim capped speed cycle dcap,exhigh shall be calculated applying the following equation to the extra high speed phase of both cycles:

Formula

9.2.2.   Determination of the time periods to be added to the interim capped speed cycle in order to compensate for distance differences

In order to compensate for a difference in distance between the base cycle and the interim capped speed cycle, corresponding time periods with vi = vcap shall be added to the interim capped speed cycle as described in the following paragraphs.

9.2.2.1.   Additional time period for the medium speed phase

If vcap < vmax,medium, the additional time period to be added to the medium speed phase of the interim capped speed cycle shall be calculated using the following equation:

Formula

The number of time samples nadd,medium with vi = vcap to be added to the medium speed phase of the interim capped speed cycle equals Δtmedium, mathematically rounded to the nearest integer (e.g. 1.4 shall be rounded to 1, 1.5 shall be rounded to 2).

9.2.2.2.   Additional time period for the high speed phase

If vcap < vmax,high, the additional time period to be added to the high speed phases of the interim capped speed cycle shall be calculated using the following equation:

Formula

The number of time samples nadd,high with vi = vcap to be added to the high speed phase of the interim capped speed cycle equals Δthigh, mathematically rounded to the nearest integer.

9.2.2.3.   The additional time period to be added to the extra high speed phase of the interim capped speed cycle shall be calculated using the following equation:

Formula

The number of time samples nadd,exhigh with vi = vcap to be added to the extra high speed phase of the interim capped speed cycle equals Δtexhigh, mathematically rounded to the nearest integer.

9.2.3.   Construction of the final capped speed cycle

9.2.3.1.   Class 1 vehicles

The first part of the final capped speed cycle consists of the vehicle speed trace of the interim capped speed cycle up to the last sample in the medium speed phase where v = vcap. The time of this sample is referred to as tmedium.

Then nadd,medium samples with vi = vcap shall be added, so that the time of the last sample is (tmedium + nadd,medium).

The remaining part of the medium speed phase of the interim capped speed cycle, which is identical with the same part of the base cycle, shall then be added, so that the time of the last sample is (1022 + nadd,medium).

9.2.3.2.   Class 2 and class 3 vehicles

 
 

9.2.3.2.1.

vcap < vmax,medium

The first part of the final capped speed cycle consists of the vehicle speed trace of the interim capped speed cycle up to the last sample in the medium speed phase where v = vcap. The time of this sample is referred to as tmedium.

The remaining part of the medium speed phase of the interim capped speed cycle, which is identical with the same part of the base cycle, shall then be added, so that the time of the last sample is (1022 + nadd,medium).

In a next step, the first part of the high speed phase of the interim capped speed cycle up to the last sample in the high speed phase where v = vcap shall be added. The time of this sample in the interim capped speed is referred to as thigh, so that the time of this sample in the final capped speed cycle is (thigh + nadd,medium).

Then, nadd,high samples with vi = vcap shall be added, so that the time of the last sample becomes (thigh + nadd,medium + nadd,high).

The remaining part of the high speed phase of the interim capped speed cycle, which is identical with the same part of the base cycle, shall then be added, so that the time of the last sample is (1477 + nadd,medium + nadd,high).

In a next step, the first part of the extra high speed phase of the interim capped speed cycle up to the last sample in the extra high speed phase where v = vcap shall be added. The time of this sample in the interim capped speed is referred to as texhigh, so that the time of this sample in the final capped speed cycle is (texhigh + nadd,medium + nadd,high).

Then nadd,exhigh samples with vi = vcap shall be added, so that the time of the last sample is (texhigh + nadd,medium + nadd,high + nadd,exhigh).

The remaining part of the extra high speed phase of the interim capped speed cycle, which is identical with the same part of the base cycle, shall then be added, so that the time of the last sample is (1800 + nadd,medium + nadd,high+ nadd,exhigh).

The length of the final capped speed cycle is equivalent to the length of the base cycle except for differences caused by the rounding process for nadd,medium, nadd,high and nadd,exhigh.

vmax, medium ≤= vcap < vmax, high

The first part of the final capped speed cycle consists of the vehicle speed trace of the interim capped speed cycle up to the last sample in the high speed phase where v = vcap. The time of this sample is referred to as thigh.

Then, nadd,high samples with vi = vcap shall be added, so that the time of the last sample is (thigh + nadd,high).

The remaining part of the high speed phase of the interim capped speed cycle, which is identical with the same part of the base cycle, shall then be added, so that the time of the last sample is (1477 + nadd,high).

In a next step, the first part of the extra high speed phase of the interim capped speed cycle up to the last sample in the extra high speed phase where v = vcap shall be added. The time of this sample in the interim capped speed is referred to as texhigh, so that the time of this sample in the final capped speed cycle is (texhigh + nadd,high).

Then nadd,exhigh samples with vi = vcap shall be added, so that the time of the last sample is (texhigh + nadd,high + nadd,exhigh).

The remaining part of the extra high speed phase of the interim capped speed cycle, which is identical with the same part of the base cycle, shall then be added, so that the time of the last sample is (1800 + nadd,high+ nadd,exhigh).

The length of the final capped speed cycle is equivalent to the length of the base cycle except for differences caused by the rounding process for nadd,high and nadd,exhigh.

 
 

9.2.3.2.3.

vmax, high <= vcap < vmax, exhigh

The first part of the final capped speed cycle consists of the vehicle speed trace of the interim capped speed cycle up to the last sample in the extra high speed phase where v = vcap. The time of this sample is referred to as texhigh.

The remaining part of the extra high speed phase of the interim capped speed cycle, which is identical with the same part of the base cycle, shall then be added, so that the time of the last sample is (1800 + nadd,exhigh).

The length of the final capped speed cycle is equivalent to the length of the base cycle except for differences caused by the rounding process for nadd,exhigh.

    General approach
 
 

1.1.

The shifting procedures described in this Sub-Annex shall apply to vehicles equipped with manual shift transmissions.

    Paragraphs 4.(a) to 4.(f) inclusive shall be applied sequentially, scanning the complete cycle trace in each case. Since modifications to paragraphs 4.(a) to 4.(f) of this Sub-Annex may create new gear use sequences, these new gear sequences shall be checked three times and modified if necessary.

    Road load measurement on road

4.1.   Requirements for road test

4.1.1.   Atmospheric conditions for road test

4.1.1.1.   Permissible wind conditions

The maximum permissible wind conditions for road load determination are described in paragraphs 4.1.1.1.1. and 4.1.1.1.2.

In order to determine the applicability of the type of anemometry to be used, the arithmetic average of the wind speed shall be determined by continuous wind speed measurement, using a recognized meteorological instrument, at a location and height above the road level alongside the test road where the most representative wind conditions will be experienced.

If tests in opposite directions cannot be performed at the same part of the test track (e.g. on an oval test track with an obligatory driving direction), wind speed and direction at each part of the test track shall be measured. In this case the higher measured value determines the type of anemometry to be used and the lower value the criterion for the allowance of waiving of a wind correction.

4.1.1.1.1.   Permissible wind conditions when using stationary anemometry

Stationary anemometry shall be used only when wind speeds over a period of 5 seconds averages less than 5 m/s and peak wind speeds are less than 8 m/s for less than 2 seconds. In addition, the vector component of the wind speed across the test road shall be less than 2 m/s. Any wind correction shall be calculated as given in paragraph 4.5.3. of this Sub-Annex. Wind correction may be waived when the lowest arithmetic average wind speed is 2 m/s or less.

4.1.1.1.2.   Wind conditions using on-board anemometry

For testing with an on-board anemometer, a device shall be used as described in paragraph 4.3.2. of this Sub-Annex. The overall arithmetic average of the wind speed during the test activity over the test road shall be less than 7 m/s with peak wind speeds of less than 10 m/s. In addition, the vector component of the wind speed across the road shall be less than 4 m/s.

4.1.1.2.   Atmospheric temperature

The atmospheric temperature should be within the range of 5 °C up to and including 35 °C.

If the difference between the highest and the lowest measured temperature during the coastdown test is more than 5 °C, the temperature correction shall be applied separately for each run with the arithmetic average of the ambient temperature of that run.

In that case the values of the road load coefficients f0, f1 and f2 shall be determined and corrected for each individual run. The final set of f0, f1 and f2 values shall be the arithmetic average of the individually corrected coefficients f0, f1 and f2 respectively.

At its option, a manufacturer may choose to perform coastdowns between 1 °C and 5 °C.

4.1.2.   Test road

The road surface shall be flat, even, clean, dry and free of obstacles or wind barriers that might impede the measurement of the road load, and its texture and composition shall be representative of current urban and highway road surfaces. The longitudinal slope of the test road shall not exceed ± 1 per cent. The local slope between any points 3 metres apart shall not deviate more than ± 0,5 per cent from this longitudinal slope. If tests in opposite directions cannot be performed at the same part of the test track (e.g. on an oval test track with an obligatory driving direction), the sum of the longitudinal slopes of the parallel test track segments shall be between 0 and an upward slope of 0,1 per cent. The maximum camber of the test road shall be 1,5 per cent.

4.2.   Preparation

4.2.1.   Test vehicle

Each test vehicle shall conform in all its components with the production series, or, if the vehicle is different from the production vehicle, a full description shall be included in all relevant test reports.

4.2.1.1.   Without using the interpolation method

A test vehicle (vehicle H) with the combination of road load relevant characteristics (i.e. mass, aerodynamic drag and tyre rolling resistance) producing the highest cycle energy demand shall be selected from the interpolation family (see paragraph 5.6. of this Annex).

If the aerodynamic influence of the different wheel rims within one interpolation family is not known, the selection shall be based on the highest expected aerodynamic drag. As a guideline, the highest aerodynamic drag may be expected for a wheel with a) the largest width, b) the largest diameter, and c) the most open structure design (in that order of importance).

The wheel selection shall be executed without prejudice to the requirement of the highest cycle energy demand.

4.2.1.2.   Using the interpolation method

At the request of the manufacturer, the interpolation method may be applied for individual vehicles in the interpolation family (see paragraph 1.2.3.1. of Sub-Annex 6 and paragraph 3.2.3.2. of Sub-Annex 7).

In this case, two test vehicles shall be selected from the interpolation family complying with the requirements of the interpolation method (paragraphs 1.2.3.1. and 1.2.3.2. of Sub-Annex 6).

Test vehicle H shall be the vehicle producing the higher, and preferably highest, cycle energy demand of that selection, test vehicle L the one producing the lower, and preferably lowest, cycle energy demand of that selection.

All items of optional equipment and/or body shapes that are chosen not to be considered in the interpolation method shall be fitted to both test vehicles H and L such that these items of optional equipment produce the highest combination of the cycle energy demand due to their road load relevant characteristics (i.e. mass, aerodynamic drag and tyre rolling resistance).

4.2.1.3.   Application of the road load family

 
 

4.2.1.3.1.

At the request of the manufacturer and upon fulfilling the criteria of paragraph 5.7. of this Annex, the road load values for vehicles H and L of an interpolation family shall be calculated.

For the purposes of paragraph 4.2.1.3. of this Sub-Annex, vehicle H of a road load family shall be designated vehicle HR. All references to vehicle H in paragraph 4.2.1. of this Sub-Annex shall be replaced by vehicle HR and all references to an interpolation family in paragraph 4.2.1. of this Sub-Annex shall be replaced by road load family.

 
 

4.2.1.3.3.

For the purposes of paragraph 4.2.1.3. of this Sub-Annex, vehicle L of a road load family shall be designated vehicle LR. All references to vehicle L in paragraph 4.2.1. of this Sub-Annex shall be replaced by vehicle LR and all references to an interpolation family in paragraph 4.2.1. of this Sub-Annex shall be replaced by road load family.

 
 

4.2.1.3.4.

Notwithstanding the requirements referring to the range of an interpolation family in paragraphs 1.2.3.1. and 1.2.3.2. of Sub-Annex 6, the difference in cycle energy demand between HR and LR of the road load family shall be at least 4 per cent and shall not exceed 35 per cent based on HR over a complete WLTC Class 3 cycle.

If more than one transmission is included in the road load family, a transmission with the highest power losses shall be used for road load determination.

 
 

4.2.1.3.5.

Road loads HR and/or LR shall be determined according to this Sub-Annex.

The road load of vehicles H (and L) of an interpolation family within the road load family shall be calculated according to paragraphs 3.2.3.2.2. to 3.2.3.2.2.4. inclusive of Sub-Annex 7, by:

 

(a)

using HR and LR of the road load family instead of H and L as inputs for the equations;

 

(b)

using the road load parameters (i.e. test mass, Δ(CD × Af) compared to vehicle LR, and tyre rolling resistance) of vehicle H (or L) of the interpolation family as inputs for the "individual vehicle";

 

(c)

repeating this calculation for each H and L vehicle of every interpolation family within the road load family.

The road load interpolation shall only be applied on those road load relevant characteristics that were identified to be different between test vehicle LR and HR. For other road load relevant characteristic(s), the value of vehicle HR shall apply.

4.2.1.4.   Application of the road load matrix family

A vehicle that fulfils the criteria of paragraph 5.8. of this Annex that is:

 

(a)

representative of the intended series of complete vehicles to be covered by the road load matrix family in terms of estimated worst CD value and body shape, and

 

(b)

representative of the intended series of vehicles to be covered by the road load matrix family in terms of estimated average of the mass of optional equipment, shall be used to determine the road load.

In the case that no representative body shape for a complete vehicle can be determined, the test vehicle shall be equipped with a square box with rounded corners with radii of maximum of 25 mm and a width equal to the maximum width of the vehicles covered by the road load matrix family, and a total height of the test vehicle of 3,0 m ± 0,1 m, including the box.

The manufacturer and the approval authority shall agree which vehicle test model is representative.

The vehicle parameters test mass, tyre rolling resistance and frontal area of both a vehicle HM and LM shall be determined in such a way that vehicle HM produces the highest cycle energy demand and vehicle LM the lowest cycle energy from the road load matrix family. The manufacturer and the approval authority shall agree on the vehicle parameters for vehicle HM and LM.

The start of the connecting tube is the exit of the tailpipe. The end of the connecting tube is the sample point, or first point of dilution.

For multiple tailpipe configurations where all the tailpipes are combined, the start of the connecting tube shall be taken at the last joint of where all the tailpipes are combined. In this case, the tube between the exit of the tailpipe and the start of the connecting tube may or may not be insulated or heated.

 
 

3.3.1.2.

The connecting tube between the vehicle and dilution system shall be designed so as to minimize heat loss.

 
 

3.3.1.3.

The connecting tube shall satisfy the following requirements:

 

(a)

Be less than 3.6 metres long, or less than 6.1 metres long if heat-insulated. Its internal diameter shall not exceed 105 mm; the insulating materials shall have a thickness of at least 25 mm and thermal conductivity shall not exceed 0,1 W/m–1K–1 at 400 °C. Optionally, the tube may be heated to a temperature above the dew point. This may be assumed to be achieved if the tube is heated to 70 °C;

 

(b)

Not cause the static pressure at the exhaust outlets on the vehicle being tested to differ by more than ± 0,75 kPa at 50 km/h, or more than ± 1,25 kPa for the duration of the test from the static pressures recorded when nothing is connected to the vehicle exhaust pipes. The pressure shall be measured in the exhaust outlet or in an extension having the same diameter and as near as possible to the end of the tailpipe. Sampling systems capable of maintaining the static pressure to within ± 0,25 kPa may be used if a written request from a manufacturer to the approval authority substantiates the need for the closer tolerance;

 

(c)

No component of the connecting tube shall be of a material that might affect the gaseous or solid composition of the exhaust gas. To avoid generation of any particles from elastomer connectors, elastomers employed shall be as thermally stable as possible and have minimum exposure to the exhaust gas. It is recommended not to use elastomer connectors to bridge the connection between the vehicle exhaust and the connecting tube.

3.3.2.   Dilution air conditioning

 
 

3.3.2.1.

The dilution air used for the primary dilution of the exhaust in the CVS tunnel shall pass through a medium capable of reducing particles of the most penetrating particle size in the filter material by ≤ 99,95 per cent, or through a filter of at least class H13 of EN 1822:2009. This represents the specification of High Efficiency Particulate Air (HEPA) filters. The dilution air may optionally be charcoal-scrubbed before being passed to the HEPA filter. It is recommended that an additional coarse particle filter be situated before the HEPA filter and after the charcoal scrubber, if used.

 
 

3.3.2.2.

At the vehicle manufacturer's request, the dilution air may be sampled according to good engineering practice to determine the tunnel contribution to background particulate and particle levels, which can be subsequently subtracted from the values measured in the diluted exhaust. See paragraph 1.2.1.3. of Sub-Annex 6.

3.3.3.   Dilution tunnel

 
 

3.3.3.1.

Provision shall be made for the vehicle exhaust gases and the dilution air to be mixed. A mixing device may be used.

 
 

3.3.3.2.

The homogeneity of the mixture in any cross-section at the location of the sampling probe shall not vary by more than ± 2 per cent from the arithmetic average of the values obtained for at least five points located at equal intervals on the diameter of the gas stream.

 
 

3.3.3.3.

For PM and PN emissions sampling, a dilution tunnel shall be used that:

 

(a)

Consists of a straight tube of electrically-conductive material that is grounded;

 

(b)

Causes turbulent flow (Reynolds number ≥ 4 000) and be of sufficient length to cause complete mixing of the exhaust and dilution air;

 

(c)

Is at least 200 mm in diameter;

 

(d)

May be insulated and/or heated.

3.3.4.   Suction device

 
 

3.3.4.1.

This device may have a range of fixed speeds to ensure sufficient flow to prevent any water condensation. This result is obtained if the flow is either:

 

(a)

Twice as high as the maximum flow of exhaust gas produced by accelerations of the driving cycle; or

 

(b)

Sufficient to ensure that the CO2 concentration in the dilute exhaust sample bag is less than 3 per cent by volume for petrol and diesel, less than 2.2 per cent by volume for LPG and less than 1.5 per cent by volume for NG/biomethane.

 
 

3.3.4.2.

Compliance with the requirements in paragraph 3.3.4.1. of this Sub-Annex may not be necessary if the CVS system is designed to inhibit condensation by such techniques, or combination of techniques, as:

 

(a)

Reducing water content in the dilution air (dilution air dehumidification);

 

(b)

Heating of the CVS dilution air and of all components up to the diluted exhaust flow measurement device and, optionally, the bag sampling system including the sample bags and also the system for the measurement of the bag concentrations.

In such cases, the selection of the CVS flow rate for the test shall be justified by showing that condensation of water cannot occur at any point within the CVS, bag sampling or analytical system.

3.3.5.   Volume measurement in the primary dilution system

 
 

3.3.5.1.

The method of measuring total dilute exhaust volume incorporated in the constant volume sampler shall be such that measurement is accurate to ± 2 per cent under all operating conditions. If the device cannot compensate for variations in the temperature of the mixture of exhaust gases and dilution air at the measuring point, a heat exchanger shall be used to maintain the temperature to within ± 6 °C of the specified operating temperature for a PDP CVS, ± 11 °C for a CFV CVS, ± 6 °C for a UFM CVS, and ± 11 °C for an SSV CVS.

 
 

3.3.5.2.

If necessary, some form of protection for the volume measuring device may be used e.g. a cyclone separator, bulk stream filter, etc.

 
 

3.3.5.3.

A temperature sensor shall be installed immediately before the volume measuring device. This temperature sensor shall have an accuracy and a precision of ± 1 °C and a response time of 0,1 seconds at 62 per cent of a given temperature variation (value measured in silicone oil).

 
 

3.3.5.4.

Measurement of the pressure difference from atmospheric pressure shall be taken upstream from and, if necessary, downstream from the volume measuring device.

 
 

3.3.5.5.

The pressure measurements shall have a precision and an accuracy of ± 0,4 kPa during the test. See Table A5/5.

3.3.6.   Recommended system description

Figure A5/3 is a schematic drawing of exhaust dilution systems that meet the requirements of this Sub-Annex.

The following components are recommended:

 

(a)

A dilution air filter, which may be pre-heated if necessary. This filter shall consist of the following filters in sequence: an optional activated charcoal filter (inlet side), and a HEPA filter (outlet side). It is recommended that an additional coarse particle filter be situated before the HEPA filter and after the charcoal filter, if used. The purpose of the charcoal filter is to reduce and stabilize the hydrocarbon concentrations of ambient emissions in the dilution air;

 

(b)

A connecting tube by which vehicle exhaust is admitted into a dilution tunnel;

 

(c)

An optional heat exchanger as described in paragraph 3.3.5.1. of this Sub-Annex;

 

(d)

A mixing device in which exhaust gas and dilution air are mixed homogeneously, and which may be located close to the vehicle so that the length of the connecting tube is minimized;

 

(e)

A dilution tunnel from which particulate and particles are sampled;

 

(f)

Some form of protection for the measurement system may be used e.g. a cyclone separator, bulk stream filter, etc.;

 

(g)

A suction device of sufficient capacity to handle the total volume of diluted exhaust gas.

Exact conformity with these figures is not essential. Additional components such as instruments, valves, solenoids and switches may be used to provide additional information and co-ordinate the functions of the component system.

Figure A5/3

Exhaust dilution system

3.3.6.1.   Positive displacement pump (PDP)

 
 

3.3.6.1.1.

A positive displacement pump (PDP) full flow exhaust dilution system satisfies the requirements of this Sub-Annex by metering the flow of gas through the pump at constant temperature and pressure. The total volume is measured by counting the revolutions made by the calibrated positive displacement pump. The proportional sample is achieved by sampling with pump, flow meter and flow control valve at a constant flow rate.

3.3.6.2.   Critical flow venturi (CFV)

 
 

3.3.6.2.1.

The use of a CFV for the full flow exhaust dilution system is based on the principles of flow mechanics for critical flow. The variable mixture flow rate of dilution and exhaust gas is maintained at sonic velocity that is directly proportional to the square root of the gas temperature. Flow is continually monitored, computed and integrated throughout the test.

 
 

3.3.6.2.2.

The use of an additional critical flow sampling venturi ensures the proportionality of the gas samples taken from the dilution tunnel. As both pressure and temperature are equal at the two venturi inlets, the volume of the gas flow diverted for sampling is proportional to the total volume of diluted exhaust gas mixture produced, and thus the requirements of this Sub-Annex are fulfilled.

 
 

3.3.6.2.3.

A measuring CFV tube shall measure the flow volume of the diluted exhaust gas.

3.3.6.3.   Subsonic flow venturi (SSV)

 
 

3.3.6.3.1.

The use of an SSV (Figure A5/4) for a full flow exhaust dilution system is based on the principles of flow mechanics. The variable mixture flow rate of dilution and exhaust gas is maintained at a subsonic velocity that is calculated from the physical dimensions of the subsonic venturi and measurement of the absolute temperature (T) and pressure (P) at the venturi inlet and the pressure in the throat of the venturi. Flow is continually monitored, computed and integrated throughout the test.

 
 

3.3.6.3.2.

An SSV shall measure the flow volume of the diluted exhaust gas.

Figure A5/4

Schematic of a subsonic venturi tube (SSV)

Image

3.3.6.4.   Ultrasonic flow meter (UFM)

 
 

3.3.6.4.1.

A UFM measures the velocity of the diluted exhaust gas in the CVS piping using the principle of ultrasonic flow detection by means of a pair, or multiple pairs, of ultrasonic transmitters/receivers mounted within the pipe as in Figure A5/5. The velocity of the flowing gas is determined by the difference in the time required for the ultrasonic signal to travel from transmitter to receiver in the upstream direction and the downstream direction. The gas velocity is converted to standard volumetric flow using a calibration factor for the tube diameter with real time corrections for the diluted exhaust temperature and absolute pressure.

 
 

3.3.6.4.2.

Components of the system include:

 

(a)

A suction device fitted with speed control, flow valve or other method for setting the CVS flow rate and also for maintaining constant volumetric flow at standard conditions;

 

(b)

A UFM;

 

(c)

Temperature and pressure measurement devices, T and P, required for flow correction;

 

(d)

An optional heat exchanger for controlling the temperature of the diluted exhaust to the UFM. If installed, the heat exchanger shall be capable of controlling the temperature of the diluted exhaust to that specified in paragraph 3.3.5.1. of this Sub-Annex. Throughout the test, the temperature of the air/exhaust gas mixture measured at a point immediately upstream of the suction device shall be within ± 6 °C of the arithmetic average operating temperature during the test.

Figure A5/5

Schematic of an ultrasonic flow meter (UFM)

Image

 

3.3.6.4.3.

The following conditions shall apply to the design and use of the UFM type CVS:

 

(a)

The velocity of the diluted exhaust gas shall provide a Reynolds number higher than 4 000 in order to maintain a consistent turbulent flow before the ultrasonic flow meter;

 

(b)

An ultrasonic flow meter shall be installed in a pipe of constant diameter with a length of 10 times the internal diameter upstream and 5 times the diameter downstream;

 

(c)

A temperature sensor (T) for the diluted exhaust shall be installed immediately before the ultrasonic flow meter. This sensor shall have an accuracy and a precision of ± 1 °C and a response time of 0,1 seconds at 62 per cent of a given temperature variation (value measured in silicone oil);

 

(d)

The absolute pressure (P) of the diluted exhaust shall be measured immediately before the ultrasonic flow meter to within ± 0,3 kPa;

 

(e)

If a heat exchanger is not installed upstream of the ultrasonic flow meter, the flow rate of the diluted exhaust, corrected to standard conditions, shall be maintained at a constant level during the test. This may be achieved by control of the suction device, flow valve or other method.

3.4.   CVS calibration procedure

3.4.1.   General requirements

 
 

3.4.1.1.

The CVS system shall be calibrated by using an accurate flow meter and a restricting device and at the intervals listed in Table A5/4. The flow through the system shall be measured at various pressure readings and the control parameters of the system measured and related to the flows. The flow metering device (e.g. calibrated venturi, laminar flow element (LFE), calibrated turbine meter) shall be dynamic and suitable for the high flow rate encountered in constant volume sampler testing. The device shall be of certified accuracy traceable to an approved national or international standard.

 
 

3.4.1.2.

The following paragraphs describe methods for calibrating PDP, CFV, SSV and UFM units using a laminar flow meter, which gives the required accuracy, along with a statistical check on the calibration validity.

3.4.2.   Calibration of a positive displacement pump (PDP)

 
 

3.4.2.1.

The following calibration procedure outlines the equipment, the test configuration and the various parameters that are measured to establish the flow rate of the CVS pump. All the parameters related to the pump are simultaneously measured with the parameters related to the flow meter that is connected in series with the pump. The calculated flow rate (given in m3/min at pump inlet for the measured absolute pressure and temperature) shall be subsequently plotted versus a correlation function that includes the relevant pump parameters. The linear equation that relates the pump flow and the correlation function shall be subsequently determined. In the case that a CVS has a multiple speed drive, a calibration for each range used shall be performed.

 
 

3.4.2.2.

This calibration procedure is based on the measurement of the absolute values of the pump and flow meter parameters relating the flow rate at each point. The following conditions shall be maintained to ensure the accuracy and integrity of the calibration curve:

 

3.4.2.2.1.

The pump pressures shall be measured at tappings on the pump rather than at the external piping on the pump inlet and outlet. Pressure taps that are mounted at the top centre and bottom centre of the pump drive head plate are exposed to the actual pump cavity pressures, and therefore reflect the absolute pressure differentials.

 

3.4.2.2.2.

Temperature stability shall be maintained during the calibration. The laminar flow meter is sensitive to inlet temperature oscillations that cause data points to be scattered. Gradual changes of ± 1 °C in temperature are acceptable as long as they occur over a period of several minutes.

 

3.4.2.2.3.

All connections between the flow meter and the CVS pump shall be free of leakage.

 
 

3.4.2.3.

During an exhaust emissions test, the measured pump parameters shall be used to calculate the flow rate from the calibration equation.

 
 

3.4.2.4.

Figure A5/6 of this Sub-Annex shows an example of a calibration set-up. Variations are permissible, provided that the approval authority approves them as being of comparable accuracy. If the set-up shown in Figure A5/6 is used, the following data shall be found within the limits of accuracy given:

 
 

Barometric pressure (corrected), Pb ± 0,03 kPa

 
 

Ambient temperature, T ± 0,2 K

 
 

Air temperature at LFE, ETI ± 0,15 K

 
 

Pressure depression upstream of LFE, EPI ± 0,01 kPa

Air temperature at CVS pump inlet, PTI ± 0,2 K

 
 

Air temperature at CVS pump outlet, PTO ± 0,2 K

 
 

Pressure depression at CVS pump inlet, PPI ± 0,22 kPa

 
 

Pressure head at CVS pump outlet, PPO ± 0,22 kPa

 
 

Pump revolutions during test period, n ± 1 min–1

 
 

Elapsed time for period (minimum 250 s), t ± 0,1 s

3.4.2.5.

After the system has been connected as shown in Figure A5/6., the variable restrictor shall be set in the wide-open position and the CVS pump shall run for 20 minutes before starting the calibration.

 
 

3.4.2.5.1.

The restrictor valve shall be reset to a more restricted condition in increments of pump inlet depression (about 1 kPa) that will yield a minimum of six data points for the total calibration. The system shall be allowed to stabilize for 3 minutes before the data acquisition is repeated.

 
 

3.4.2.5.2.

The air flow rate Qs at each test point shall be calculated in standard m3/min from the flow meter data using the manufacturer's prescribed method.

 
 

3.4.2.5.3.

The air flow rate shall be subsequently converted to pump flow V0 in m3/rev at absolute pump inlet temperature and pressure.

Formula

where:

n

is the pump speed, min–1.

 
 

3.4.2.5.4.

To compensate for the interaction of pump speed pressure variations at the pump and the pump slip rate, the correlation function x0 between the pump speed n, the pressure differential from pump inlet to pump outlet and the absolute pump outlet pressure shall be calculated using the following equation:

Formula

where:

 

x0

is the correlation function;

ΔPp

is the pressure differential from pump inlet to pump outlet, kPa;

Pe

absolute outlet pressure (PPO + Pb), kPa.

A linear least squares fit shall be performed to generate the calibration equations having the following form:

Formula

Formula

where B and M are the slopes, and A and D0 are the intercepts of the lines.

 
 

3.4.2.6.

A CVS system having multiple speeds shall be calibrated at each speed used. The calibration curves generated for the ranges shall be approximately parallel and the intercept values, D0 shall increase as the pump flow range decreases.

 
 

3.4.2.7.

The calculated values from the equation shall be within 0.5 per cent of the measured value of V0. Values of M will vary from one pump to another. A calibration shall be performed at initial installation and after major maintenance.

3.4.3.   Calibration of a critical flow venturi (CFV)

 
 

3.4.3.1.

Calibration of a CFV is based upon the flow equation for a critical venturi:

Formula

where:

 

Qs

is the flow, m3/min;

Kv

is the calibration coefficient;

P

is the absolute pressure, kPa;

T

is the absolute temperature, Kelvin (K).

Gas flow is a function of inlet pressure and temperature.

The calibration procedure described in paragraph 3.4.3.2. to 3.4.3.3.3.4. inclusive of this Sub-Annex establishes the value of the calibration coefficient at measured values of pressure, temperature and air flow.

 
 

3.4.3.2.

Measurements for flow calibration of a critical flow venturi are required and the following data shall be within the limits of precision given:

 
 

Barometric pressure (corrected), Pb ± 0,03 kPa,

 
 

LFE air temperature, flow meter, ETI ± 0,15 K,

 
 

Pressure depression upstream of LFE, EPI ± 0,01 kPa,

 
 

Pressure drop across LFE matrix, EDP ± 0,0015 kPa,

 
 

Air flow, Qs± 0,5 per cent,

 
 

CFV inlet depression, PPI ± 0,02 kPa,

 
 

Temperature at venturi inlet, Tv ± 0,2 K.

 
 

3.4.3.3.

The equipment shall be set up as shown in Figure A5/7 and checked for leaks. Any leaks between the flow-measuring device and the critical flow venturi will seriously affect the accuracy of the calibration and shall therefore be prevented.

Figure A5/7

CFV calibration configuration

Image

 

3.4.3.3.1.

The variable-flow restrictor shall be set to the open position, the suction device shall be started and the system stabilized. Data from all instruments shall be collected.

 
 

3.4.3.3.2.

The flow restrictor shall be varied and at least eight readings across the critical flow range of the venturi shall be made.

 
 

3.4.3.3.3.

The data recorded during the calibration shall be used in the following calculation:

 
 

3.4.3.3.3.1.

The air flow rate, Qs at each test point shall be calculated from the flow meter data using the manufacturer's prescribed method.

Values of the calibration coefficient shall be calculated for each test point:

Formula

where:

 

Qs

is the flow rate, m3/min at 273,15 K (0 °C) and 101,325, kPa;

Tv

is the temperature at the venturi inlet, Kelvin (K);

Pv

is the absolute pressure at the venturi inlet, kPa.

 
 

3.4.3.3.3.2.

Kv shall be plotted as a function of venturi inlet pressure Pv. For sonic flow Kv will have a relatively constant value. As pressure decreases (vacuum increases), the venturi becomes unchoked and Kv decreases. These values of Kv shall not be used for further calculations.

 
 

3.4.3.3.3.3.

For a minimum of eight points in the critical region, an arithmetic average Kv and the standard deviation shall be calculated.

 
 

3.4.3.3.3.4.

If the standard deviation exceeds 0,3 per cent of the arithmetic average Kv, corrective action shall be taken.

3.4.4.   Calibration of a subsonic venturi (SSV)

3.4.4.1.   Calibration of the SSV is based upon the flow equation for a subsonic venturi. Gas flow is a function of inlet pressure and temperature, and the pressure drop between the SSV inlet and throat.

3.4.4.2.   Data analysis

 
 

3.4.4.2.1.

The airflow rate, Qssv, at each restriction setting (minimum 16 settings) shall be calculated in standard m3/s from the flow meter data using the manufacturer's prescribed method. The discharge coefficient, Cd, shall be calculated from the calibration data for each setting using the following equation:

Formula

where:

 

Qssv

is the airflow rate at standard conditions (101,325 kPa, 273,15 K (0 °C)), m3/s;

T

is the temperature at the venturi inlet, Kelvin (K);

dV

is the diameter of the SSV throat, m;

rp

is the ratio of the SSV throat pressure to inlet absolute static pressure, Formula;

rD

is the ratio of the SSV throat diameter, dV, to the inlet pipe inner diameter D;

Cd

is the discharge coefficient of the SSV;

Pp

is the absolute pressure at venturi inlet, kPa.

To determine the range of subsonic flow, Cd shall be plotted as a function of Reynolds number Re at the SSV throat. The Reynolds number at the SSV throat shall be calculated using the following equation:

Formula

where:

Formula

 

A1

is 25.55152 in SI, Formula;

Qssv

is the airflow rate at standard conditions (101,325 kPa, 273,15 K (0 °C)), m3/s;

dv

is the diameter of the SSV throat, m;

μ

is the absolute or dynamic viscosity of the gas, kg/ms;

b

is 1,458 × 106 (empirical constant), kg/ms K0.5;

S

is 110,4 (empirical constant), Kelvin (K).

 
 

3.4.4.2.2.

Because QSSV is an input to the Re equation, the calculations shall be started with an initial guess for QSSV or Cd of the calibration venturi, and repeated until QSSV converges. The convergence method shall be accurate to at least 0.1 per cent.

 
 

3.4.4.2.3.

For a minimum of sixteen points in the region of subsonic flow, the calculated values of Cd from the resulting calibration curve fit equation shall be within ± 0,5 per cent of the measured Cd for each calibration point.

3.4.5.1.   The UFM shall be calibrated against a suitable reference flow meter.

3.4.5.2.   The UFM shall be calibrated in the CVS configuration that will be used in the test cell (diluted exhaust piping, suction device) and checked for leaks. See Figure A5/8.

3.4.5.3.   A heater shall be installed to condition the calibration flow in the event that the UFM system does not include a heat exchanger.

3.4.5.4.   For each CVS flow setting that will be used, the calibration shall be performed at temperatures from room temperature to the maximum that will be experienced during vehicle testing.

3.4.5.5.   The manufacturer's recommended procedure shall be followed for calibrating the electronic portions (temperature (T) and pressure (P) sensors) of the UFM.

3.4.5.6.   Measurements for flow calibration of the ultrasonic flow meter are required and the following data (in the case that a laminar flow element is used) shall be found within the limits of precision given:

 
 

Barometric pressure (corrected), Pb ± 0,03 kPa,

 
 

LFE air temperature, flow meter, ETI ± 0,15 K,

 
 

Pressure depression upstream of LFE, EPI ± 0,01 kPa,

 
 

Pressure drop across (EDP) LFE matrix ± 0,0015 kPa,

 
 

Air flow, Qs ± 0,5 per cent,

 
 

UFM inlet depression, Pact ± 0,02 kPa,

 
 

Temperature at UFM inlet, Tact ± 0,2 K.

3.4.5.7.   Procedure

 
 

3.4.5.7.1.

The equipment shall be set up as shown in Figure A5/8 and checked for leaks. Any leaks between the flow-measuring device and the UFM will seriously affect the accuracy of the calibration.

Figure A5/8

UFM calibration configuration

Image

 

3.4.5.7.2.

The suction device shall be started. Its speed and/or the position of the flow valve shall be adjusted to provide the set flow for the validation and the system stabilised. Data from all instruments shall be collected.

 
 

3.4.5.7.3.

For UFM systems without a heat exchanger, the heater shall be operated to increase the temperature of the calibration air, allowed to stabilise and data from all the instruments recorded. The temperature shall be increased in reasonable steps until the maximum expected diluted exhaust temperature expected during the emissions test is reached.

 
 

3.4.5.7.4.

The heater shall be subsequently turned off and the suction device speed and/or flow valve shall be adjusted to the next flow setting that will be used for vehicle emissions testing after which the calibration sequence shall be repeated.

3.4.5.8.   The data recorded during the calibration shall be used in the following calculations. The air flow rate Qs at each test point shall be calculated from the flow meter data using the manufacturer's prescribed method.

Formula

where:

 

Qs

is the air flow rate at standard conditions (101,325 kPa, 273,15 K (0 °C)), m3/s;

Qreference

is the air flow rate of the calibration flow meter at standard conditions (101,325 kPa, 273,15 K (0 °C)), m3/s;

Kv

is the calibration coefficient.

For UFM systems without a heat exchanger, Kv shall be plotted as a function of Tact.

The maximum variation in Kv shall not exceed 0,3 per cent of the arithmetic average Kv value of all the measurements taken at the different temperatures.

3.5.   System verification procedure

3.5.1.   General requirements

3.5.1.1.   The total accuracy of the CVS sampling system and analytical system shall be determined by introducing a known mass of an emissions gas compound into the system whilst it is being operated under normal test conditions and subsequently analysing and calculating the emission gas compounds according to the equations of Sub-Annex 7. The CFO method described in paragraph 3.5.1.1.1. of this Sub-Annex and the gravimetric method described in paragraph 3.5.1.1.2. of this Sub-Annex are both known to give sufficient accuracy.

The maximum permissible deviation between the quantity of gas introduced and the quantity of gas measured is 2 per cent.

3.5.1.1.1.   Critical flow orifice (CFO) method

The CFO method meters a constant flow of pure gas (CO, CO2, or C3H8) using a critical flow orifice device.

 
 

3.5.1.1.1.1.

A known mass of pure carbon monoxide, carbon dioxide or propane gas shall be introduced into the CVS system through the calibrated critical orifice. If the inlet pressure is high enough, the flow rate q which is restricted by means of the critical flow orifice, is independent of orifice outlet pressure (critical flow). The CVS system shall be operated as in a normal exhaust emissions test and enough time shall be allowed for subsequent analysis. The gas collected in the sample bag shall be analysed by the usual equipment (paragraph 4.1. of this Sub-Annex) and the results compared to the concentration of the known gas samples If deviations exceed 2 per cent, the cause of the malfunction shall be determined and corrected.

3.5.1.1.2.   Gravimetric method

The gravimetric method weighs a quantity of pure gas (CO, CO2, or C3H8).

 
 

3.5.1.1.2.1.

The weight of a small cylinder filled with either pure carbon monoxide, carbon dioxide or propane shall be determined with a precision of ± 0,01 g. The CVS system shall operate under normal exhaust emissions test conditions while the pure gas is injected into the system for a time sufficient for subsequent analysis. The quantity of pure gas involved shall be determined by means of differential weighing. The gas accumulated in the bag shall be analysed by means of the equipment normally used for exhaust gas analysis as described in paragraph 4.1. of this Sub-Annex). The results shall be subsequently compared to the concentration figures computed previously. If deviations exceed 2 per cent, the cause of the malfunction shall be determined and corrected.

4.2.1.2.   General requirements

 
 

4.2.1.2.1.

The sampling probe for the test gas flow for particulate shall be arranged within the dilution tunnel so that a representative sample gas flow can be taken from the homogeneous air/exhaust mixture and shall be upstream of a heat exchanger (if any).

 
 

4.2.1.2.2.

The particulate sample flow rate shall be proportional to the total mass flow of diluted exhaust gas in the dilution tunnel to within a tolerance of ± 5 per cent of the particulate sample flow rate. The verification of the proportionality of the particulate sampling shall be made during the commissioning of the system and as required by the approval authority.

 
 

4.2.1.2.3.

The sampled dilute exhaust gas shall be maintained at a temperature above 20 °C and below 52 °C within 20 cm upstream or downstream of the particulate sampling filter face. Heating or insulation of components of the particulate sampling system to achieve this is permitted.

In the event that the 52 °C limit is exceeded during a test where periodic regeneration event does not occur, the CVS flow rate shall be increased or double dilution shall be applied (assuming that the CVS flow rate is already sufficient so as not to cause condensation within the CVS, sample bags or analytical system).

 
 

4.2.1.2.4.

The particulate sample shall be collected on a single filter mounted within a holder in the sampled dilute exhaust gas flow.

 
 

4.2.1.2.5.

All parts of the dilution system and the sampling system from the exhaust pipe up to the filter holder that are in contact with raw and diluted exhaust gas shall be designed to minimise deposition or alteration of the particulate. All parts shall be made of electrically conductive materials that do not react with exhaust gas components, and shall be electrically grounded to prevent electrostatic effects.

 
 

4.2.1.2.6.

If it is not possible to compensate for variations in the flow rate, provision shall be made for a heat exchanger and a temperature control device as specified in paragraphs 3.3.5.1. or 3.3.6.4.2. of this Sub-Annex, so as to ensure that the flow rate in the system is constant and the sampling rate accordingly proportional.

The accuracy of the flow meters used for the measurement and control of the double diluted exhaust passing through the particulate sampling filters and for the measurement/control of secondary dilution air shall be sufficient so that the differential volume Vep shall meet the accuracy and proportional sampling requirements specified for single dilution.

The requirement that no condensation of the exhaust gas occur in the CVS dilution tunnel, diluted exhaust flow rate measurement system, CVS bag collection or analysis systems shall also apply in the case that double dilution systems are used.

 
 

4.2.1.2.11.

Each flow meter used in a particulate sampling and double dilution system shall be subjected to a linearity verification as required by the instrument manufacturer.

5.2.   Analyser calibration procedures

 
 

5.2.1.

Each analyser shall be calibrated as specified by the instrument manufacturer or at least as often as specified in Table A5/3.

 
 

5.2.2.

Each normally used operating range shall be linearized by the following procedure:

 

5.2.2.1.

The analyser linearization curve shall be established by at least five calibration points spaced as uniformly as possible. The nominal concentration of the calibration gas of the highest concentration shall be not less than 80 per cent of the full scale.

 

5.2.2.2.

The calibration gas concentration required may be obtained by means of a gas divider, diluting with purified N2 or with purified synthetic air.

 

5.2.2.3.

The linearization curve shall be calculated by the least squares method. If the resulting polynomial degree is greater than 3, the number of calibration points shall be at least equal to this polynomial degree plus 2.

 

5.2.2.4.

The linearization curve shall not differ by more than ± 2 per cent from the nominal value of each calibration gas.

 

5.2.2.5.

From the trace of the linearization curve and the linearization points it is possible to verify that the calibration has been carried out correctly. The different characteristic parameters of the analyser shall be indicated, particularly:

 

(a)

Analyser and gas component;

 

(b)

Range;

 

(c)

Date of linearisation.

 

5.2.2.6.

If the approval authority is satisfied that alternative technologies (e.g. computer, electronically controlled range switch, etc.) give equivalent accuracy, these alternatives may be used.

5.3.   Analyser zero and calibration verification procedure

5.3.1.   Each normally used operating range shall be checked prior to each analysis in accordance with paragraphs 5.3.1.1. and 5.3.1.2. of this Sub-Annex

 
 

5.3.1.1.

The calibration shall be checked by use of a zero gas and by use of a calibration gas according to paragraph 1.2.14.2.3. of Sub-Annex 6,

 
 

5.3.1.2.

After testing, zero gas and the same calibration gas shall be used for re-checking according to paragraph 1.2.14.2.4. of Sub-Annex 6.

5.4.   FID hydrocarbon response check procedure

5.4.1.   Detector response optimization

The FID shall be adjusted as specified by the instrument manufacturer. Propane in air shall be used on the most common operating range.

5.4.2.   Calibration of the HC analyser

 
 

5.4.2.1.

The analyser shall be calibrated using propane in air and purified synthetic air.

 
 

5.4.2.2.

A calibration curve as described in paragraph 5.2.2. of this Sub-Annex shall be established.

5.4.3.   Response factors of different hydrocarbons and recommended limits

The response factor Rf for a particular hydrocarbon compound is the ratio of the FID C1 reading to the gas cylinder concentration, expressed as ppm C1.

The concentration of the test gas shall be at a level to give a response of approximately 80 per cent of full-scale deflection for the operating range. The concentration shall be known to an accuracy of ± 2 per cent in reference to a gravimetric standard expressed in volume. In addition, the gas cylinder shall be preconditioned for 24 hours at a temperature between 20 and 30 °C.

 
 

5.4.3.2.

Response factors shall be determined when introducing an analyser into service and at major service intervals thereafter. The test gases to be used and the recommended response factors are:

Propylene and purified air: Formula

Toluene and purified air: Formula

These are relative to an Rf of 1,00 for propane and purified air.

5.5.   NOx converter efficiency test procedure

 
 

5.5.1.

Using the test set up as shown in Figure A5/15 and the procedure described below, the efficiency of converters for the conversion of NO2 into NO shall be tested by means of an ozonator as follows:

 

5.5.1.1.

The analyser shall be calibrated in the most common operating range following the manufacturer's specifications using zero and calibration gas (the NO content of which shall amount to approximately 80 per cent of the operating range and the NO2 concentration of the gas mixture shall be less than 5 per cent of the NO concentration). The NOx analyser shall be in the NO mode so that the calibration gas does not pass through the converter. The indicated concentration shall be included in all relevant test sheets.

 

5.5.1.2.

Via a T-fitting, oxygen or synthetic air shall be added continuously to the calibration gas flow until the concentration indicated is approximately 10 per cent less than the indicated calibration concentration given in paragraph 5.5.1.1. of this Sub-Annex. The indicated concentration (c) shall be included in all relevant test sheets. The ozonator shall be kept deactivated throughout this process.

 

5.5.1.3.

The ozonator shall now be activated to generate enough ozone to bring the NO concentration down to 20 per cent (minimum 10 per cent) of the calibration concentration given in paragraph 5.5.1.1. of this Sub-Annex. The indicated concentration (d) shall be included all relevant test sheets.

 

5.5.1.4.

The NOx analyser shall be subsequently switched to the NOx mode, whereby the gas mixture (consisting of NO, NO2, O2 and N2) now passes through the converter. The indicated concentration (a) shall be included in all relevant test sheets.

 

5.5.1.5.

The ozonator shall now be deactivated. The mixture of gases described in paragraph 5.5.1.2. of this Sub-Annex shall pass through the converter into the detector. The indicated concentration (b) shall be included in all relevant test sheets.

Figure A5/15

NOx converter efficiency test configuration

5.5.1.6.

With the ozonator deactivated, the flow of oxygen or synthetic air shall be shut off. The NO2 reading of the analyser shall then be no more than 5 per cent above the figure given in paragraph 5.5.1.1. of this Sub-Annex.

 

5.5.1.7.

The per cent efficiency of the NOx converter shall be calculated using the concentrations a, b, c and d determined in paragraphs 5.5.1.2. to 5.5.1.5. of this Sub-Annex inclusive using the following equation:

Formula

5.5.1.7.1.

The efficiency of the converter shall not be less than 95 per cent. The efficiency of the converter shall be tested in the frequency defined in Table A5/3.

5.6.   Calibration of the microgram balance

 
 

5.6.1.

The calibration of the microgram balance used for particulate sampling filter weighing shall be traceable to a national or international standard. The balance shall comply with the linearity requirements given in paragraph 4.2.2.2. of this Sub-Annex. The linearity verification shall be performed at least every 12 months or whenever a system repair or change is made that could influence the calibration.

5.7.   Calibration and validation of the particle sampling system

Examples of calibration/validation methods are available at:

http://www.unece.org/trans/main/wp29/wp29wgs/wp29grpe/pmpFCP.html

5.7.1.   Calibration of the PNC

 
 

5.7.1.1.

The approval authority shall ensure the existence of a calibration certificate for the PNC demonstrating compliance with a traceable standard within a 13-month period prior to the emissions test. Between calibrations either the counting efficiency of the PNC shall be monitored for deterioration or the PNC wick shall be routinely changed every 6 months. See Figures A5/16 and A5/17. PNC counting efficiency may be monitored against a reference PNC or against at least two other measurement PNCs. If the PNC reports particle number concentrations within ± 10 per cent of the arithmetic average of the concentrations from the reference PNC, or a group of two or more PNCs, the PNC shall subsequently be considered stable, otherwise maintenance of the PNC is required. Where the PNC is monitored against two or more other measurement PNCs, it is permitted to use a reference vehicle running sequentially in different test cells each with its own PNC.

5.7.1.2.

The PNC shall also be recalibrated and a new calibration certificate issued following any major maintenance.

 
 

5.7.1.3.

Calibration shall be traceable to a national or international standard calibration method by comparing the response of the PNC under calibration with that of:

 

(a)

A calibrated aerosol electrometer when simultaneously sampling electrostatically classified calibration particles; or

 

(b)

A second PNC that has been directly calibrated by the method described above.

 
 

5.7.1.3.1.

In paragraph 5.7.1.3. (a) of this Sub-Annex, calibration shall be undertaken using at least six standard concentrations spaced as uniformly as possible across the PNC’s measurement range.

 
 

5.7.1.3.2.

In paragraph 5.7.1.3. (b) of this Sub-Annex, calibration shall be undertaken using at least six standard concentrations across the PNC’s measurement range. At least 3 points shall be at concentrations below 1,000 per cm3, the remaining concentrations shall be linearly spaced between 1,000 per cm3 and the maximum of the PNC’s range in single particle count mode.

 
 

5.7.1.3.3.

In paragraphs 5.7.1.3.(a) and 5.7.1.3.(b) of this Sub-Annex, the selected points shall include a nominal zero concentration point produced by attaching HEPA filters of at least class H13 of EN 1822:2008, or equivalent performance, to the inlet of each instrument. With no calibration factor applied to the PNC under calibration, measured concentrations shall be within ± 10 per cent of the standard concentration for each concentration, with the exception of the zero point, otherwise the PNC under calibration shall be rejected. The gradient from a linear least squares regression of the two data sets shall be calculated and recorded. A calibration factor equal to the reciprocal of the gradient shall be applied to the PNC under calibration. Linearity of response is calculated as the square of the Pearson product moment correlation coefficient (r) of the two data sets and shall be equal to or greater than 0.97. In calculating both the gradient and r2, the linear regression shall be forced through the origin (zero concentration on both instruments).

 
 

5.7.1.4.

Calibration shall also include a check, according to the requirements of paragraph 4.3.1.3.4.(h) of this Sub-Annex, on the PNC’s detection efficiency with particles of 23 nm electrical mobility diameter. A check of the counting efficiency with 41 nm particles is not required.

5.7.2.   Calibration/validation of the VPR

 
 

5.7.2.1.

Calibration of the VPR’s particle concentration reduction factors across its full range of dilution settings, at the instrument’s fixed nominal operating temperatures, shall be required when the unit is new and following any major maintenance. The periodic validation requirement for the VPR’s particle concentration reduction factor is limited to a check at a single setting, typical of that used for measurement on particulate filter-equipped vehicles. The approval authority shall ensure the existence of a calibration or validation certificate for the VPR within a 6-month period prior to the emissions test. If the VPR incorporates temperature monitoring alarms, a 13 month validation interval is permitted.

It is recommended that the VPR is calibrated and validated as a complete unit.

The VPR shall be characterised for particle concentration reduction factor with solid particles of 30, 50 and 100 nm electrical mobility diameter. Particle concentration reduction factors fr(d) for particles of 30 nm and 50 nm electrical mobility diameters shall be no more than 30 per cent and 20 per cent higher respectively, and no more than 5 per cent lower than that for particles of 100 nm electrical mobility diameter. For the purposes of validation, the arithmetic average of the particle concentration reduction factor shall be within ± 10 per cent of the arithmetic average particle concentration reduction factor Formula determined during the primary calibration of the VPR.

 
 

5.7.2.2.

The test aerosol for these measurements shall be solid particles of 30, 50 and 100 nm electrical mobility diameter and a minimum concentration of 5 000 particles per cm3 at the VPR inlet. As an option, a polydisperse aerosol with an electrical mobility median diameter of 50 nm may be used for validation. The test aerosol shall be thermally stable at the VPR operating temperatures. Particle number concentrations shall be measured upstream and downstream of the components.

The particle concentration reduction factor for each monodisperse particle size, fr (di), shall be calculated using the following equation:

Formula

where:

 

Nin(di)

is the upstream particle number concentration for particles of diameter di;

Nout(di)

is the downstream particle number concentration for particles of diameter di;

di

is the particle electrical mobility diameter (30, 50 or 100 nm).

Nin(di) and Nout(di) shall be corrected to the same conditions.

The arithmetic average particle concentration reduction factor Formula at a given dilution setting shall be calculated using the following equation:

Formula

Where a polydisperse 50 nm aerosol is used for validation, the arithmetic average particle concentration reduction factor Formula at the dilution setting used for validation shall be calculated using the following equation:

Formula

where:

 

Nin

is the upstream particle number concentration;

Nout

is the downstream particle number concentration.

 
 

5.7.2.3.

The VPR shall demonstrate greater than 99.0 per cent removal of tetracontane (CH3(CH2)38CH3) particles of at least 30 nm electrical mobility diameter with an inlet concentration ≥ 10 000 per cm3 when operated at its minimum dilution setting and manufacturers recommended operating temperature.

5.7.3.   PN measurement system check procedures

 
 

5.7.3.1.

On a monthly basis, the flow into the PNC shall have a measured value within 5 per cent of the PNC nominal flow rate when checked with a calibrated flow meter.

5.8.   Accuracy of the mixing device

In the case that a gas divider is used to perform the calibrations as defined in paragraph 5.2. of this Sub-Annex, the accuracy of the mixing device shall be such that the concentrations of the diluted calibration gases may be determined to within ± 2 per cent. A calibration curve shall be verified by a mid-span check as described in paragraph 5.3. of this Sub-Annex. A calibration gas with a concentration below 50 per cent of the analyser range shall be within 2 per cent of its certified concentration.

Type 1 test procedures and test conditions

  • 1. 
    Test procedures and test conditions

1.1   Description of tests

1.1.1.   The Type 1 test is used to verify the emissions of gaseous compounds, particulate matter, particle number, CO2 mass emission, fuel consumption, electric energy consumption and electric ranges over the applicable WLTP test cycle.

1.1.1.1.   The tests shall be carried out according to the method described in paragraph 1.2. of this Sub-Annex or paragraph 3. of Sub-Annex 8 for pure electric, hybrid electric and compressed hydrogen fuel cell hybrid vehicles. Exhaust gases, particulate matter and particles shall be sampled and analysed by the prescribed methods.

1.1.2.   The number of tests shall be determined according to the flowchart in Figure A6/1. The limit value is the maximum allowed value for the respective criteria pollutant as specified in Annex I of Regulation (EC) No 715/2007.

1.1.2.1.   The flowchart in Figure A6/1 shall be applicable only to the whole applicable WLTP test cycle and not to single phases.

1.1.2.2.   The test results shall be the values after the REESS energy change-based, Ki and ATCT corrections are applied.

1.1.2.3.   Determination of total cycle values

 
 

1.1.2.3.1.

If during any of the tests a criteria emissions limit is exceeded, the vehicle shall be rejected.

 
 

1.1.2.3.2.

Depending on the vehicle type, the manufacturer shall declare as applicable the total cycle value of the CO2 mass emission, the electric energy consumption, fuel consumption for NOVC-FCHV as well as PER and AER according to Table A6/1.

 
 

1.1.2.3.3.

The declared value of the electric energy consumption for OVC-HEVs under charge-depleting operating condition shall not be determined according to Figure A6/1. It shall be taken as the type approval value if the declared CO2 value is accepted as the approval value. If that is not the case, the measured value of electric energy consumption shall be taken as the type approval value.

 
 

1.1.2.3.4.

If after the first test all criteria in row 1 of the applicable Table A6/2 are fulfilled, all values declared by the manufacturer shall be accepted as the type approval value. If any one of the criteria in row 1 of the applicable Table A6/2 is not fulfilled, a second test shall be performed with the same vehicle.

 
 

1.1.2.3.5.

After the second test, the arithmetic average results of the two tests shall be calculated. If all criteria in row 2 of the applicable Table A6/2 are fulfilled by these arithmetic average results, all values declared by the manufacturer shall be accepted as the type approval value. If any one of the criteria in row 2 of the applicable Table A6/2 is not fulfilled, a third test shall be performed with the same vehicle.

 
 

1.1.2.3.6.

After the third test, the arithmetic average results of the three tests shall be calculated. For all parameters which fulfil the corresponding criterion in row 3 of the applicable Table A6/2, the declared value shall be taken as the type approval value. For any parameter which does not fulfil the corresponding criterion in row 3 of the applicable Table A6/2, the arithmetic average result shall be taken as the type approval value.

 
 

1.1.2.3.7.

In the case that any one of the criterion of the applicable Table A6/2 is not fulfilled after the first or second test, at the request of the manufacturer and with the approval of the approval authority, the values may be re-declared as higher values for emissions or consumption, or as lower values for electric ranges, in order to reduce the required number of tests for type approval.

 
 

1.1.2.3.8.

dCO21, dCO22 and dCO23 determination.

 
 

1.1.2.3.8.1.

Without prejudice to the requirement of paragraph 1.1.2.3.8.2., the following values for dCO21, dCO22 and dCO23 shall be used in relation to the criteria for the number of tests in Table A6/2:

dCO21 = 0,990

dCO22 = 0,995

dCO23 = 1,000

 
 

1.1.2.3.8.2.

If the charge depleting Type 1 test for OVC-HEVs consists of two or more applicable WLTP test cycles and the dCO2x value is below 1,0, the dCO2x value shall be replaced by 1,0.

 
 

1.1.2.3.9.

In the case that a test result or an average of test results was taken and confirmed as the type approval value, this result shall be referred to as ‘declared value’ for further calculations.

1.2.1.2.   The Type 1 test shall consist of vehicle operation on a chassis dynamometer on the applicable WLTC for the interpolation family. A proportional part of the diluted exhaust emissions shall be collected continuously for subsequent analysis using a constant volume sampler.

1.2.1.3.   Background concentrations shall be measured for all compounds for which dilute mass emissions measurements are conducted. For exhaust emissions testing, this requires sampling and analysis of the dilution air.

1.2.1.3.1.   Background particulate measurement

 
 

1.2.1.3.1.1.

Where the manufacturer requests subtraction of either dilution air or dilution tunnel background particulate mass from emissions measurements, these background levels shall be determined according to the procedures listed in paragraphs 1.2.1.3.1.1.1. to 1.2.1.3.1.1.3. inclusive of this Sub-Annex.

 
 

1.2.1.3.1.1.1.

The maximum permissible background correction shall be a mass on the filter equivalent to 1 mg/km at the flow rate of the test.

 
 

1.2.1.3.1.1.2.

If the background exceeds this level, the default figure of 1 mg/km shall be subtracted.

 
 

1.2.1.3.1.1.3.

Where subtraction of the background contribution gives a negative result, the background level shall be considered to be zero.

 
 

1.2.1.3.1.2.

Dilution air background particulate mass level shall be determined by passing filtered dilution air through the particulate background filter. This shall be drawn from a point immediately downstream of the dilution air filters. Background levels in g/m3 shall be determined as a rolling arithmetic average of at least 14 measurements with at least one measurement per week.

 
 

1.2.1.3.1.3.

Dilution tunnel background particulate mass level shall be determined by passing filtered dilution air through the particulate background filter. This shall be drawn from the same point as the particulate matter sample. Where secondary dilution is used for the test, the secondary dilution system shall be active for the purposes of background measurement. One measurement may be performed on the day of test, either prior to or after the test.

1.2.1.3.2.   Background particle number determination

 
 

1.2.1.3.2.1.

Where a manufacturer requests a background correction, these background levels shall be determined as follows:

 
 

1.2.1.3.2.1.1.

The background value may be either calculated or measured. The maximum permissible background correction shall be related to the maximum allowable leak rate of the particle number measurement system (0,5 particles per cm3) scaled from the particle concentration reduction factor, PCRF, and the CVS flow rate used in the actual test;

 
 

1.2.1.3.2.1.2.

Either the approval authority or the manufacturer may request that actual background measurements are used instead of calculated ones.

 
 

1.2.1.3.2.1.3.

Where subtraction of the background contribution gives a negative result, the PN result shall be considered to be zero.

 
 

1.2.1.3.2.2.

Dilution air background particle number level shall be determined by sampling filtered dilution air. This shall be drawn from a point immediately downstream of the dilution air filters into the PN measurement system. Background levels in particles per cm3 shall be determined as a rolling arithmetic average of least 14 measurements with at least one measurement per week.

 
 

1.2.1.3.2.3.

Dilution tunnel background particle number level shall be determined by sampling filtered dilution air. This shall be drawn from the same point as the PN sample. Where secondary dilution is used for the test the secondary dilution system shall be active for the purposes of background measurement. One measurement may be performed on the day of test, either prior to or after the test using the actual PCRF and the CVS flow rate utilised during the test.

As soon as practical prior to analysis, the analyser range to be used for each compound shall be set to zero with the appropriate zero gas.

 
 

1.2.14.2.3.

The calibration curves of the analysers shall be set by means of calibration gases of nominal concentrations of 70 to 100 per cent of the range.

 
 

1.2.14.2.4.

The zero settings of the analysers shall be subsequently rechecked: if any reading differs by more than 2 per cent of the range from that set in paragraph 1.2.14.2.2. of this Sub-Annex, the procedure shall be repeated for that analyser.

 
 

1.2.14.2.5.

In both cases, (a) and (b), the same analyser range shall be used for the corresponding ambient air and exhaust bags.

1.2.14.3.   Particulate sample filter weighing

 
 

1.2.14.3.1.

The particulate sample filter shall be returned to the weighing chamber (or room) no later than 1 hour after completion of the test. It shall be conditioned in a petri dish, which is protected against dust contamination and allows air exchange, for at least 1 hour, and weighed. The gross weight of the filter shall be included in all relevant test sheets.

 
 

1.2.14.3.2.

At least two unused reference filters shall be weighed within 8 hours of, but preferably at the same time as, the sample filter weighings. Reference filters shall be of the same size and material as the sample filter.

 
 

1.2.14.3.3.

If the specific weight of any reference filter changes by more than ± 5 μg between sample filter weighings, the sample filter and reference filters shall be reconditioned in the weighing chamber (or room) and reweighed.

 
 

1.2.14.3.4.

The comparison of reference filter weighings shall be made between the specific weights and the rolling arithmetic average of that reference filter's specific weights. The rolling arithmetic average shall be calculated from the specific weights collected in the period after the reference filters were placed in the weighing chamber (or room). The averaging period shall be at least one day but not more than 15 days.

 
 

1.2.14.3.5.

Multiple reconditionings and reweighings of the sample and reference filters are permitted until a period of 80 hours has elapsed following the measurement of gases from the emissions test. If, prior to or at the 80 hour point, more than half the number of reference filters meet the ± 5 μg criterion, the sample filter weighing may be considered valid. If, at the 80 hour point, two reference filters are employed and one filter fails the ± 5 μg criterion, the sample filter weighing may be considered valid under the condition that the sum of the absolute differences between specific and rolling means from the two reference filters shall be less than or equal to 10 μg.

 
 

1.2.14.3.6.

In the case that less than half of the reference filters meet the ± 5 μg criterion, the sample filter shall be discarded, and the emissions test repeated. All reference filters shall be discarded and replaced within 48 hours. In all other cases, reference filters shall be replaced at least every 30 days and in such a manner that no sample filter is weighed without comparison to a reference filter that has been present in the weighing chamber (or room) for at least one day.

 
 

1.2.14.3.7.

If the weighing chamber (or room) stability criteria outlined in paragraph 4.2.2.1. of Sub-Annex 5 are not met, but the reference filter weighings meet the above criteria, the vehicle manufacturer has the option of accepting the sample filter weights or voiding the tests, repairing the weighing chamber (or room) control system and re-running the test.

Sub-Annex 6

Appendix 1

Emissions test procedure for all vehicles equipped with periodically regenerating systems

  • 1. 
    General
 
 

1.1.

This Appendix defines the specific provisions regarding testing a vehicle equipped with periodically regenerating systems as defined in paragraph 3.8.1. of this Annex.

Upon request of the manufacturer and with approval of the approval authority, a manufacturer may develop an alternative procedure to demonstrate its equivalency, including filter temperature, loading quantity and distance driven. This may be done on an engine bench or on a chassis dynamometer.

Alternatively to carrying out the test procedures defined in this Appendix, a fixed Ki value of 1,05 may be used for CO2 and fuel consumption.

 
 

1.2.

During cycles where regeneration occurs, emission standards need not apply. If a periodic regeneration occurs at least once per Type 1 test and has already occurred at least once during vehicle preparation, it does not require a special test procedure. In this case, this Appendix does not apply.

 
 

1.3.

The provisions of this Appendix shall apply for the purposes of PM measurements only and not PN measurements.

 
 

1.4.

At the request of the manufacturer, and with approval of the approval authority, the test procedure specific to periodically regenerating systems will not apply to a regenerative device if the manufacturer provides data demonstrating that, during cycles where regeneration occurs, emissions remain below the emissions limits for the relevant vehicle category.

 
 

1.5.

At the request of the manufacturer and with the agreement of the approval authority the Extra High phase may be excluded for determining the regenerative factor K_i for Class 2 and Class 3 vehicles.

  • 2. 
    Test Procedure

The test vehicle shall be capable of inhibiting or permitting the regeneration process provided that this operation has no effect on original engine calibrations. Prevention of regeneration is only permitted during loading of the regeneration system and during the preconditioning cycles. It is not permitted during the measurement of emissions during the regeneration phase. The emission test shall be carried out with the unchanged, original equipment manufacturer's (OEM) control unit. At the request of the manufacturer and with approval of the approval authority, an ‘engineering control unit’ which has no effect on original engine calibrations may be used during Ki determination.

2.1.   Exhaust emissions measurement between two WLTCs with regeneration events

 
 

2.1.1.

The arithmetic average emissions between regeneration events and during loading of the regenerative device shall be determined from the arithmetic mean of several approximately equidistant (if more than two) Type 1 tests. As an alternative, the manufacturer may provide data to show that the emissions remain constant (± 15 per cent) on WLTCs between regeneration events. In this case, the emissions measured during the Type 1 test may be used. In any other case, emissions measurements for at least two Type 1 cycles shall be completed: one immediately after regeneration (before new loading) and one as close as possible prior to a regeneration phase. All emissions measurements shall be carried out according to this Sub-Annex and all calculations shall be carried out according to paragraph 3. of this Appendix.

 
 

2.1.2.

The loading process and determination shall be made during the Type 1 driving cycle on a chassis dynamometer or on an engine test bench using an equivalent test cycle. These cycles may be run continuously (i.e. without the need to switch the engine off between cycles). After any number of completed cycles, the vehicle may be removed from the chassis dynamometer and the test continued at a later time.

 
 

2.1.3.

The number of cycles D between two WLTCs where regeneration events occur, the number of cycles over which emission measurements are made n and mass emissions measurement M′sij for each compound i over each cycle j shall be included in all relevant test sheets.

2.2.   Measurement of emissions during regeneration events

 
 

2.2.1.

Preparation of the vehicle, if required, for the emissions test during a regeneration phase, may be completed using the preconditioning cycles in paragraph 1.2.6. of this Sub-Annex or equivalent engine test bench cycles, depending on the loading procedure chosen in paragraph 2.1.2. of this Sub-Annex.

 
 

2.2.2.

The test and vehicle conditions for the Type 1 test described in this Annex apply before the first valid emission test is carried out.

 
 

2.2.3.

Regeneration shall not occur during the preparation of the vehicle. This may be ensured by one of the following methods:

 

2.2.3.1.

A ‘dummy’ regenerating system or partial system may be fitted for the preconditioning cycles.

 

2.2.3.2.

Any other method agreed between the manufacturer and the approval authority.

 
 

2.2.4.

A cold start exhaust emissions test including a regeneration process shall be performed according to the applicable WLTC.

 
 

2.2.5.

If the regeneration process requires more than one WLTC, each WLTC shall be completed. Use of a single particulate sample filter for multiple cycles required to complete regeneration is permissible.

 
 

2.2.5.1.

If more than one WLTC is required, subsequent WLTC(s) shall be driven immediately, without switching the engine off, until complete regeneration has been achieved. In the case that the number of gaseous emission bags required for the multiple cycles would exceed the number of bags available, the time necessary to set up a new test shall be as short as possible. The engine shall not be switched off during this period.

 
 

2.2.6.

The emission values during regeneration Mri for each compound i shall be calculated according to paragraph 3. in this Appendix. The number of applicable test cycles d measured for complete regeneration shall be included in all relevant test sheets.

Appendix 5

Utility factors (UF) for OVC-HEVs

 
 

1.

Utility Factors (UFs) are ratios based on driving statistics and the ranges achieved in charge-depleting mode and charge-sustaining modes for OVC-HEVs and are used for weighting emissions, CO2 emissions and fuel consumptions.

The database used to calculate the Utility Factors in paragraph 2. was predominantly based on the use characteristics (e.g. utilization, daily driven distance, shares of different vehicle classes) of conventional vehicles. It will be necessary to re-evaluate UF and charging frequencies by a customer study once a significant number of OVC-HEV vehicles are in use in the European market.

 
 

2.

For the calculation of each phase specific utility factor (UF), the following equation shall be applied:

Formula

Where:

 

UFi

Utility factor for phase i.

di

Distance driven to the end of phase i in km.

Cj

jth coefficient (see Table A8.App5/1).

dn

Normalized distance (see Table A8.App5/1).

k

Amount of terms and coefficients in the exponent (see Table A8.App5/1).

i

Number of considered phase.

j

Number of considered term/coefficient.

Formula

Sum of calculated utility factors up to phase (i-1).

The curve that is based on the following parameters in Table A8.App5/1 is valid from 0 km to the normalized distance dn where the UF converges to 1.0 (as can be seen in Figure A8/App5/1).
