COMMISSION REGULATION (EU) 2017/2400

of 12 December 2017

implementing Regulation (EC) No 595/2009 of the European Parliament and of the Council as regards the determination of the CO2 emissions and fuel consumption of heavy-duty vehicles and amending Directive 2007/46/EC of the European Parliament and of the Council and Commission Regulation (EU) No 582/2011

(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 595/2009 of the European Parliament and of the Council of 18 June 2009 on type-approval of motor vehicles and engines with respect to emissions from heavy duty vehicles (Euro VI) and on access to vehicle repair and maintenance information and amending Regulation (EC) No 715/2007 and Directive 2007/46/EC and repealing Directives 80/1269/EEC, 2005/55/EC and 2005/78/EC (1), and in particular Article 4(3) and Article 5(4)(e) 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(7) thereof,

Whereas:

(1)

Regulation (EC) No 595/2009 is one of the separate regulatory acts under the type-approval procedure laid down by Directive 2007/46/EC. It empowers the Commission to adopt measures relating to CO2 emissions and fuel consumption of heavy duty vehicles. The present Regulation aims at establishing measures for obtaining accurate information on CO2 emissions and fuel consumption of new heavy-duty vehicles placed on the Union market.

(2)

Directive 2007/46/EC sets out the necessary requirements for the purpose of a whole vehicle type-approval.

(3)

Commission Regulation (EU) No 582/2011 (3) sets out requirements for the approval of heavy-duty vehicles with regard to emissions and access to vehicle repair and maintenance information. Measures for the determination of CO2 emissions and fuel consumption of new heavy-duty vehicles should be part of the type-approval system instituted by this Regulation. A licence to perform simulations to establish CO2 emissions and fuel consumption of a vehicle will be required to obtain the approvals mentioned above.

(4)

Emissions from lorries, buses and coaches, which are the most widely representative categories of heavy-duty vehicles, currently represent around 25 % of road transport CO2 emissions and are expected to increase even further in the future. In order to reach the target of a 60 % reduction of CO2 emissions from transport by 2050, effective measures to curb emissions from heavy-duty vehicles need to be introduced.

(5)

Until now, no common method has been laid down by Union legislation to measure CO2 emissions and fuel consumption of heavy-duty vehicles, rendering it impossible to objectively compare performance of vehicles or to introduce measures, whether on the Union or national level, that would encourage the introduction of more energy-efficient vehicles. As a consequence, there has been no transparency in the market as regards the energy-efficiency of heavy-duty vehicles.

(6)

The heavy-duty vehicle sector is very diversified, with a significant number of different vehicle types and models as well as with a high degree of customisation. The Commission has conducted an in-depth analysis of the available options to measure CO2 emissions and fuel consumption of those vehicles and concluded that in order to obtain unique data for each produced vehicle at the lowest cost, CO2 emissions and fuel consumption of heavy-duty vehicles should be determined using simulation software.

(7)

In order to reflect the diversity of the sector, heavy-duty vehicles should be divided into groups of vehicles with a similar axle configuration, chassis configuration and technically permissible maximum laden mass. Those parameters define the purpose of a vehicle and should therefore determine the set of test cycles used for the purpose of the simulation.

(8)

Since there is no software available on the market to meet the requirements necessary for the purposes of the assessment of CO2 emissions and fuel consumption of heavy-duty vehicles, the Commission should develop dedicated software to be used for those purposes.

(9)

That software should be publically available, open-source, downloadable and executable. It should include a simulation tool for the calculation of CO2 emissions and fuel consumption of specific heavy-duty vehicles. The tool should be conceived to use, as input, the data reflecting the characteristics of the components, separate technical units and systems which have a significant impact on the CO2 emissions and fuel consumption of heavy-duty vehicles – engine, gearbox and additional driveline components, axles, tyres, aerodynamics and auxiliaries. The software should also include pre-processing tools to be used for the verification and pre-processing of the simulation tool input data relating to the engine and vehicle air drag, as well as a hashing tool to be used for the encryption of the simulation tool input and output files.

(10)

In order to enable a realistic assessment, the simulation tool should be equipped with a number of functionalities allowing for a simulation of vehicles with different payloads and fuels over specific test cycles assigned to a vehicle depending on its application.

(11)

Recognizing the importance of the proper functioning of the software for the correct determination of vehicles' CO2 emissions and fuel consumption and of keeping up with technological progress, the Commission should maintain the software and update it whenever necessary.

(12)

The simulations should be performed by vehicle manufacturers before registration, sale or entry into service of a new vehicle in the Union. Provisions should also be put in place for the licence of the vehicle manufacturers' processes for calculation of the CO2 emissions and fuel consumption of vehicles. The processes of handling and application of data by the vehicle manufacturers for the purposes of calculation of the CO2 emissions and fuel consumption of vehicles using the simulation tool should be assessed and closely monitored by the approval authorities in order to ensure that the simulations are conducted in a correct manner. Provisions should therefore be put in place requiring vehicle manufacturers to acquire a licence for the operation of the simulation tool.

(13)

The CO2 emissions and fuel consumption related properties of the components, separate technical units and systems having a significant impact on the CO2 emissions and fuel consumption of heavy-duty vehicles should be used as input for the simulation tool.

(14)

In order to reflect the specificities of the individual components, separate technical units and systems and to allow for a more precise determination of their CO2 emissions and fuel consumption related properties, provisions for the certification of such properties on the basis of testing should be set out.

(15)

For the purpose of limiting the costs of the certification, manufacturers should have the possibility to group into families components, separate technical units and systems with similar design and CO2 emission and fuel consumption characteristics. One component, separate technical unit or system per family with the least favourable characteristics as regards CO2 emissions and fuel consumption within that family should be tested and its results should apply to the entire family.

(16)

The costs related to testing may constitute a significant obstacle in particular to companies manufacturing components, separate technical units or systems in small numbers. In order to provide an economically viable alternative to certification, standard values should be set out for certain components, separate technical units and systems with the possibility of using those values instead of the certified values determined on the basis of testing. Standard values should, however, be set out in a way to encourage suppliers of components, separate technical units and systems to apply for certification.

(17)

In order to ensure that the results relating to CO2 emissions and fuel consumption declared by the suppliers of components, separate technical units and systems as well as vehicle manufacturers are correct, provisions for verifying and ensuring the conformity of the simulation tool operation as well as of the CO2 emissions and fuel consumption related properties of the relevant components, separate technical units and systems should be set out.

(18)

In order to ensure sufficient lead time for the national authorities and the industry, the obligation to determine and declare CO2 emissions and fuel consumption of new vehicles should be implemented gradually for different vehicle groups starting with the vehicles which are the biggest contributors to CO2 emissions of the heavy-duty sector.

(19)

The provisions set out in this Regulation form part of the framework established by Directive 2007/46/EC and complement the provisions for type approval with regard to emissions and vehicle repair and maintenance information laid down in Regulation (EU) No 582/2011. To establish a clear relationship between those provisions and this Regulation, Directive 2007/46/EC and Regulation (EU) No 582/2011 should be amended accordingly.

(20)

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

HAS ADOPTED THIS REGULATION:

3.   General requirements

The calibration laboratory facilities shall comply with the requirements of either ISO/TS 16949, ISO 9000 series or ISO/IEC 17025. All laboratory reference measurement equipment, used for calibration and/or verification, shall be traceable to national or international standards.

Engines shall be grouped into engine CO2-families defined in accordance with Appendix 3. Paragraph 4.1 explains which testruns shall be performed for the purpose of certification of one specific engine CO2-family.

3.1   Test conditions

All testruns performed for the purpose of certification of one specific engine CO2-family defined in accordance with Appendix 3 to this Annex shall be conducted on the same physical engine and without any changes to the setup of the engine dynamometer and the engine system, apart from the exceptions defined in paragraph 4.2 and Appendix 3.

3.1.1   Laboratory test conditions

The tests shall be conducted under ambient conditions meeting the following conditions over the whole testrun:

(1)

The parameter fa describing the laboratory test conditions, determined in accordance with paragraph 6.1 of Annex 4 to UN/ECE Regulation 49 Rev.06, shall be within the following limits: 0,96 ≤ fa ≤ 1,04.

If tests are performed in test cells that are able to simulate barometric conditions other than those existing in the atmosphere at the specific test site, the applicable fa value shall be determined with the simulated values of atmospheric pressure by the conditioning system. The same reference value for the simulated atmospheric pressure shall be used for the intake air and exhaust path and all other relevant engine systems. The actual value of the simulated atmospheric pressure for the intake air and exhaust path and all other relevant engine systems shall be within the limits specified in subpoint (3).

In cases where the ambient pressure in the atmosphere at the specific test site exceeds the upper limit of 102 kPa, tests in accordance with this Annex may still be performed. In this case tests shall be performed with the specific ambient air pressure in the atmosphere.

In cases where the test cell has the ability to control temperature, pressure and/or humidity of engine intake air independent of the atmospheric conditions the same settings for those parameters shall be used for all testruns performed for the purpose of certification of one specific engine CO2-family defined in accordance with Appendix 3 to this Annex.

3.1.2   Engine installation

The test engine shall be installed in accordance with paragraphs 6.3 to 6.6 of Annex 4 to UN/ECE Regulation 49 Rev.06.

If auxiliaries/equipment necessary for operating the engine system are not installed as required in accordance with paragraph 6.3 of Annex 4 to UN/ECE Regulation 49 Rev.06, all measured engine torque values shall be corrected for the power required for driving these components for the purpose of this Annex in accordance with paragraph 6.3 of Annex 4 to UN/ECE Regulation 49 Rev.06.

The power consumption of the following engine components resulting in the engine torque required for driving these engine components shall be determined in accordance with Appendix 5 to this Annex:

(1)

fan

(2)

electrically powered auxiliaries/equipment necessary for operating the engine system

3.1.3   Crankcase emissions

In the case of a closed crankcase, the manufacturer shall ensure that the engine's ventilation system does not permit the emission of any crankcase gases into the atmosphere. If the crankcase is of an open type, the emissions shall be measured and added to the tailpipe emissions, following the provisions set out in paragraph 6.10. of Annex 4 to UN/ECE Regulation 49 Rev.06.

3.1.4   Engines with charge air-cooling

During all testruns the charge air cooling system used on the test bed shall be operated under conditions which are representative for in-vehicle application at reference ambient conditions. The reference ambient conditions are defined as 293 K for air temperature and 101,3 kPa for pressure.

The laboratory charge air cooling for tests according to this regulation should comply with the provisions specified in paragraph 6.2 of Annex 4 to UN/ECE Regulation 49 Rev.06.

3.1.5   Engine cooling system

(1)

During all testruns the engine cooling system used on the test bed shall be operated under conditions which are representative for in-vehicle application at reference ambient conditions. The reference ambient conditions are defined as 293 K for air temperature and 101,3 kPa for pressure.

(2)

The engine cooling system should be equipped with thermostats according to the manufacturer specification for vehicle installation. If either a non-operational thermostat is installed or no thermostat is used, subpoint (3) shall apply. The setting of the cooling system shall be performed in accordance with subpoint (4).

(3)

If no thermostat is used or a non-operational thermostat is installed, the test bed system shall reflect the behavior of the thermostat under all test conditions. The setting of the cooling system shall be performed in accordance with subpoint (4).

(4)

The engine coolant flow rate (or alternatively the pressure differential across the engine side of the heat exchanger) and the engine coolant temperature shall be set to a value representative for in-vehicle application at reference ambient conditions when the engine is operated at rated speed and full load with the engine thermostat in fully open position. This setting defines the coolant reference temperature. For all testruns performed for the purpose of certification of one specific engine within one engine CO2-family, the cooling system setting shall not be changed, neither on the engine side nor on the test bed side of the cooling system. The temperature of the test bed side cooling medium should be kept resonably constant by good engineering judgement. The cooling medium on the test bed side of the heat exchanger shall not exceed the nominal thermostat opening temperatur downstream of the heat exchanger.

(5)

For all testruns performed for the purpose of certification of one specific engine within one engine CO2-family the engine coolant temperature shall be maintained between the nominal value of the thermostat opening temperature declared by the manufacturer and the coolant reference temperature in accordance with subpoint (4) as soon as the engine coolant has reached the declared thermostat opening temperature after engine cold start.

(6)

For the WHTC coldstart test performed in accordance with paragraph 4.3.3, the specific initial conditions are specified in paragraphs 7.6.1. and 7.6.2 of Annex 4 to UN/ECE Regulation 49 Rev.06. If simulation of the thermostat behaviour in accordance with subpoint (3) is applied, there shall be no coolant flow across the heat exchanger as long as the engine coolant has not reached the declared nominal thermostat opening temperature after cold start.

3.2   Fuels

The respective reference fuel for the engine systems under test shall be selected from the fuel types listed in Table 1. The fuel properties of the reference fuels listed in Table 1 shall be those specified in Annex IX to Commission Regulation (EU) No 582/2011.

To ensure that the same fuel is used for all testruns performed for the purpose of certification of one specific engine CO2-family no refill of the tank or switch to another tank supplying the engine system shall occur. Exceptionally a refill or switch may be allowed if it can be ensured that the replacement fuel has exactly the same properties as the fuel used before (same production batch).

The NCV for the fuel used shall be determined by two separate measurements in accordance with the respective standards for each fuel type defined in Table 1. The two separate measurements shall be performed by two different labs independent from the manufacturer applying for certification. The lab performing the measurements shall comply with the requirements of ISO/IEC 17025. The approval authority shall ensure that the fuel sample used for determination of the NCV is taken from the batch of fuel used for all testruns.

If the two separate values for the NCV are deviating by more than 440 Joule per gram fuel, the values determined shall be void and the measurement campaign shall be repeated.

The mean value of the two separate NCV that are not deviating by more than 440 Joule per gram fuel shall be documented in MJ/kg rounded to 3 places to the right of the decimal point in accordance with ASTM E 29-06.

For gas fuels the standards for determining the NCV according to Table 1 contain the calculation of the calorific value based on the fuel composition. The gas fuel composition for determining the NCV shall be taken from the analysis of the reference gas fuel batch used for the certification tests. For the determination of the gas fuel composition used for determining the NCV only one single analysis by a lab independent from the manufacturer applying for certification shall be performed. For gas fuels the NCV shall be determined based on this single analysis instead of a mean value of two separate measurements.

The engine speeds nidle, nlo, npref, n95h and nhi shall be determined from the engine full load curve of the CO2-parent engine of the engine CO2-family defined in accordance with Appendix 3 to this Annex and recorded in accordance with paragraph 4.3.1 by applying the definitions of characteristic engine speeds in accordance with paragraph 7.4.6. of Annex 4 to UN/ECE Regulation 49 Rev.06.

The engine speed n57 shall be determined by the following equation:

n57 = 0,565 × (0,45 × nlo + 0,45 × npref + 0,1 × nhi – nidle) × 2,0327 + nidle

The 4 base target engine speed setpoints are defined as follows:

(1)

Base engine speed 1: nidle

(2)

Base engine speed 2: nA = n57 – 0,05 × (n95h – nidle)

(3)

Base engine speed 3: nB = n57 + 0,08 × (n95h – nidle)

(4)

Base engine speed 4: n95h

The potential distances between the speed setpoints shall be determined by the following equations:

(1)

dnidleA_44 = (nA – nidle) / 4

(2)

dnB95h_44 = (n95h – nB) / 4

(3)

dnidleA_35 = (nA – nidle) / 3

(4)

dnB95h_35 = (n95h – nB) / 5

(5)

dnidleA_53 = (nA – nidle) / 5

(6)

dnB95h_53 = (n95h – nB) / 3

The absolute values of potential deviations between the two sections shall be determined by the following equations:

(1)

dn44 = ABS(dnidleA_44 – dnB95h_44)

(2)

dn35 = ABS(dnidleA_35 – dnB95h_35)

(3)

dn53 = ABS(dnidleA_53 – dnB95h_53)

The 6 additional target engine speed setpoints shall be determined based on the smallest of the three values dn44, dn35 and dn53 in accordance with the following provisions:

(1)

If dn44 is the smallest of the three values, the 6 additional target engine speeds shall be determined by dividing each of the two ranges, one from nidle to nA and the other from nB to n95h, into 4 equidistant sections.

(2)

If dn35 is the smallest of the three values, the 6 additional target engine speeds shall be determined by dividing the range from nidle to nA into 3 equidistant sections and the range from nB to n95h, into 5 equidistant sections.

(3)

If dn53 is the smallest of the three values, the 6 additional target engine speeds shall be determined by dividing the range from nidle to nA into 5 equidistant sections and the range from nB to n95h, into 3 equidistant sections.

The actual values for nact, Mact and Pact shall be the determined from the values recorded in accordance with paragraph 4.3.5.3.

The ramps to move from one target setpoint to the next shall be excluded from this regression analysis.

To minimize the biasing effect of the time lag between the actual and reference cycle values, the entire engine speed and torque actual signal sequence may be advanced or delayed in time with respect to the reference speed and torque sequence. If the actual signals are shifted, both speed and torque shall be shifted by the same amount in the same direction.

The method of least squares shall be used for the regression analysis in accordance with paragraphs A.3.1 and A.3.2 of Appendix 3 to Annex 4 to UN/ECE Regulation 49 Rev.06, with the best-fit equation having the form as defined in paragraph 7.8.7 of Annex 4 to UN/ECE Regulation 49 Rev.06.

For the purposes of this regression analysis only, omissions of points are permitted where noted in Table 4 (Permitted point omissions from regression analysis) of Annex 4 to UN/ECE Regulation 49 Rev.06 before doing the regression calculation. Additionally, all engine torque and power values at points with maximum operator demand shall be omitted for the purposes of this regression analysis only. However, points omitted for the purposes of regression analysis shall not be omitted for any other calculations in accordance with this Annex. Point omission may be applied to the whole or to any part of the cycle.

For the data to be considered valid, the criteria of Table 3 (Regression line tolerances for the WHSC) of Annex 4 to UN/ECE Regulation 49 Rev.06 shall be met.

4.3.5.7.2   Requirements for emission monitoring

2.2   Notwithstanding the provisions in point 2.1, a minimum number of 30 shall be used for nCOP,base.

2.3   The resulting figure for nCOP,base determined in accordance with points 2.1 and 2.2 of this Appendix shall be divided by 10 and the result rounded to the nearest whole number in order to determine the number of engine CO2-families to be tested annually, nCOP,fam, for verifying conformity of the certified CO2 emissions and fuel consumption related properties.

2.4   In the case that a manufacturer has less CO2-families than nCOP,fam determined in accordance with point 2.3, the number of CO2-families to be tested, nCOP,fam, shall be defined by the total number of CO2-families of the manufacturer.

3.   Selection of engine CO2-families to be tested

From the number of engine CO2-families to be tested determined in accordance with paragraph 2 of this Appendix, the first two CO2-families shall be those with the highest production volumes.

The remaining number of engine CO2-families to be tested shall be randomly selected from all existing engine CO2-families and shall be agreed between the manufacturer and the approval authority.

4.   Testrun to be performed

The minimum number of engines to be tested for each engine CO2-family, nCOP,min, shall be determined by dividing nCOP,base by nCOP,fam, both values determined in accordance with point 2. If the resulting value for nCOP,min is smaller than 4 it shall be set to 4.

Conformity of the certified CO2 emissions and fuel consumption related properties shall be verified by testing the engines in the WHSC test in accordance with paragraph 4.3.4.

All boundary conditions as specified in this Annex for the certification testing shall apply, except for the following:

(1)

The laboratory test conditions in accordance with paragraph 3.1.1 of this Annex. The conditions in accordance with paragraph 3.1.1 are recommended and shall not be mandatory. Deviations may occur under certain ambient conditions at the testing site and should be minimized by the use of good engineering judgment.

(2)

In case reference fuel of the type B7 (Diesel / CI) in accordance with paragraph 3.2 of this Annex is used, the determination of the NCV in accordance with paragraph 3.2 of this Annex shall not be required.

(3)

In case market fuel or reference fuel other than B7 (Diesel / CI) is used, the NCV of the fuel shall be determined in accordance with the applicable standards defined in Table 1 of this Annex. With exemption of gas engines the NCV measurement shall be performed by only one lab independent from the engine manufacturer instead of two as required in accordance with paragraph 3.2 of this Annex. NCV for reference gas fuels (G25, LPG fuel B) shall be calculated according to the applicable standards in Table 1 of this Annex from the fuel analysis submitted by the reference gas fuel supplier.

(4)

The lubricating oil shall be the one filled during engine production and shall not be changed for the purpose of testing conformity of CO2 emissions and fuel consumption related properties.

5.   Run-in of newly manufactured engines

5.1   The tests shall be carried out on newly manufactured engines taken from the series production which have a maximum run-in time of 15 hours before the testrun for the verification of conformity of the certified CO2 emissions and fuel consumption related properties in accordance with paragraph 4 of this Appendix is started.

5.2   At the request of the manufacturer, the tests may be carried out on engines which have been run-in up to a maximum of 125 hours. In this case, the running-in procedure shall be conducted by the manufacturer who shall not make any adjustments to those engines.

5.3   When the manufacturer requests to conduct a running-in procedure in accordance with point 5.2 of this Appendix it may be carried out on either of the following:

(a)

all the engines that are tested

(b)

newly produced engine, with the determination of an evolution coefficient as follows:

A.

The specific fuel consumption shall be measured over the WHSC test once on the newly manufactured engine with a maximum run-in time of 15 hours in accordance with point 5.1 of this Appendix and in the second test before the maximum of 125 hours set in point 5.2 of this Appendix on the first engine tested.

B.

The values for the specific fuel consumption of both tests shall be adjusted to a corrected value in accordance with paragraphs 7.2 and 7.3 of this Appendix for the respective fuel used during each of the two tests.

C.

The evolution coefficient of the fuel consumption shall be calculated by dividing the corrected specific fuel consumption of the second test by the corrected specific fuel consumption of the first test. The evolution coefficient may have a value less than one.

5.4   If the provisions defined in point 5.3 (b) of this Appendix are applied, the subsequent engines selected for testing of conformity of CO2 emissions and fuel consumption related properties shall not be subjected to the running-in procedure, but their specific fuel consumption over the WHSC determined on the newly manufactured engine with a maximum run-in time of 15 hours in accordance with point 5.1 of this Appendix shall be multiplied by the evolution coefficient.

5.5   In the case described in point 5.4 of this Appendix the values for the specific fuel consumption over the WHSC to be taken shall be the following:

for the engine used for determination of the evolution coefficient in accordance with point 5.3 (b) of this Appendix, the value from the second test

(b)

for the other engines, the values determined on the newly manufactured engine with a maximum run-in time of 15 hours in accordance with point 5.1 of this Appendix multiplied by the evolution coefficient determined in accordance with point 5.3 (b)(C) of this Appendix

5.6.   Instead of using a running-in procedure in accordance with points 5.2 to 5.5 of this Appendix, a generic evolution coefficient of 0,99 may be used at the request of the manufacturer. In this case the specific fuel consumption over the WHSC determined on the newly manufactured engine with a maximum run-in time of 15 hours in accordance with point 5.1 of this Appendix shall be multiplied by the generic evolution coefficient of 0,99.

5.7   If the evolution coefficient in accordance with point 5.3 (b) of this Appendix is determined using the parent engine of an engine family according to paragraphs 5.2.3. and 5.2.4. of Annex 4 to Regulation UN/ECE R.49.06, it may be carried across to all members of any CO2-family belonging to the same engine family according to paragraph 5.2.3. of Annex 4 to Regulation UN/ECE R.49.06.

6.   Target value for assessment of conformity of the certified CO2 emissions and fuel consumption related properties

The target value to assess the conformity of the certified CO2 emissions and fuel consumption related properties shall be the corrected specific fuel consumption over the WHSC, SFCWHSC,corr, in g/kWh determined in accordance with paragraph 5.3.3 and documented in the information document as part of the certificates set out in Appendix 2 to this Annex for the specific engine tested.

7.   Actual value for assessment of conformity of the certified CO2 emissions and fuel consumption related properties

7.1   The specific fuel consumption over the WHSC, SFCWHSC, shall be determined in accordance with paragraph 5.3.3 of this Annex from the testruns performed in accordance with paragraph 4 of this Appendix. At the request of the manufacturer the specific fuel consumption value determined shall be modified by applying the provisions defined in points 5.3 to 5.6 of this Appendix.

7.2   If market fuel was used during testing in accordance with point 1.4 of this Appendix, the specific fuel consumption over the WHSC, SFCWHSC, determined in point 7.1 of this Appendix shall be adjusted to a corrected value, SFCWHSC,corr, in accordance with paragraph 5.3.3.1 of this Annex.

7.3   If reference fuel was used during testing in accordance with point 1.4 of this Appendix the special provisions defined in paragraph 5.3.3.2 of this Annex shall be applied to the value determined in point 7.1 of this Appendix.

7.4   The measured emission of gaseous pollutants over the WHSC performed in accordance with paragraph 4 shall be adjusted by application of the appropriate deterioration factors (DF's) for that engine as recorded in the Addendum to the EC type-approval certificate granted in accordance with Commission Regulation (EU) No 582/2011.

8.   Limit for conformity of one single test

For diesel engines, the limit values for the assessment of conformity of one single engine tested shall be the target value determined in accordance with point (6) + 3 percent.

For gas engines, the limit values for the assessment of conformity of one single engine tested shall be the target value determined in accordance with point (6) + 4 percent.

9.   Assessment of conformity of the certified CO2 emissions and fuel consumption related properties

9.1   The emission test results over the WHSC determined in accordance with point 7.4 of this Appendix shall meet the applicable limits values defined in Annex I to Regulation (EC) No 595/2009 for all gaseous pollutants except ammonia, otherwise the test shall be considered void for the assessment of conformity of the certified CO2 emissions and fuel consumption related properties.

9.2   A single test of one engine tested in accordance with paragraph 4 of this Appendix shall be considered as nonconforming if the actual value in accordance with paragraph 7 of this Appendix is higher than the limit values defined in accordance with paragraph 8 of this Appendix.

9.3   For the current sample size of engines tested within one CO2-family in accordance with paragraph 4 of this Appendix the test statistic quantifying the cumulative number of nonconforming tests in accordance with point 9.2 of this Appendix at the nth test shall be determined.

(a)

If the cumulative number of nonconforming tests at the nth test determined in accordance with point 9.3 of this Appendix is less than or equal to the pass decision number for the sample size given in Table 4 of Appendix 3 to UN/ECE Regulation 49 Rev.06, a pass decision is reached.

(b)

If the cumulative number of nonconforming tests at the nth test determined in accordance with point 9.3 of this Appendix is greater than or equal to the fail decision number for the sample size given in Table 4 of Appendix 3 to UN/ECE Regulation 49 Rev.06, a fail decision is reached.

(c)

Otherwise, an additional engine is tested in accordance with paragraph 4 of this Appendix and the calculation procedure in accordance with point 9.3 of this Appendix is applied to the sample increased by one more unit.

9.4   If neither a pass nor a fail decision is reached, the manufacturer may at any time decide to stop testing. In that case a fail decision is recorded.

Appendix 5

Determination of power consumption of engine components

1.   Fan

The engine torque shall be measured at engine motoring with and without fan engaged with the following procedure:

(i)

Install the fan according to product instruction before the test starts.

(ii)

Warm up phase: The engine shall be warmed up according to the recommendation of the manufacturer and by practicing good engineering judgement (eg operating the engine for 20 minutes at mode 9, as defined in Table 1 of paragraph 7.2.2. of Annex 4 to UN/ECE Regulation 49 Rev.06).

(iii)

Stabilization phase: After the warm-up or optional warmup step (v) is completed the engine shall be operated with minimum operator demand (motoring) at engine speed npref for 130 ± 2 seconds with the fan disengaged (nfan_disengage < 0,25 * nengine * rfan) The first 60 ± 1 seconds of this period are considered as a stabilization period, during which the actual engine speed shall be held within ±5 min– 1 of npref.

(iv)

Measurement phase: During the following period of 60 ± 1 seconds the actual engine speed shall be held within ± 2 min– 1 of npref and the coolant temperature within ± 5 °C while the torque for motoring the engine with the fan disengaged, the fan speed and the engine speed shall be recorded as an average value over this period of 60 ± 1 seconds. The remaining period of 10 ± 1 seconds shall be used for data post-processing and storage if necessary.

(v)

Optional warmup phase: Upon manufacturer's request and according to good engineering judgement step (ii) can be repeated (e.g. if the temperature has dropped more than 5 °C)

(vi)

Stabilization phase: After the optional warm-up is completed the engine shall be operated with minimum operator demand (motoring) at engine speed npref for 130 ± 2 seconds with the fan engaged (nfan_engage > 0,9 * nengine * rfan) The first 60 ± 1 seconds of this period are considered as a stabilization period, during which the actual engine speed shall be held within ± 5 min– 1 of npref.

(vii)

Measurement phase: During the following period of 60 ± 1 seconds the actual engine speed shall be held within ± 2 min– 1 of npref and the coolant temperature within ± 5 °C while the torque for motoring the engine with the fan engaged, the fan speed and the engine speed shall be recorded as an average value over this period of 60 ± 1 seconds. The remaining period of 10±1 seconds shall be used for data post-processing and storage if necessary.

(viii)

Steps (iii) to (vii) shall be repeated at engine speeds n95h and nhi instead of npref, with an optional warmup step (v) before each stabilization step if needed to maintain a stable coolant temperature (± 5 °C), according to good engineering judgement.

(ix)

If the standard deviation of all calculated Ci according to the equation below at the three speeds npref, n95h and nhi is equal or higher than 3 percent, the measurement shall be performed for all engine speeds defining the grid for the fuel mapping procedure (FCMC) according to paragraph 4.3.5.2.1.

The actual fan constant shall be calculated from the measurement data according to the following equation:

Formula

where:

Ci

fan constant at certain engine speed

MDfan_disengage

measured engine torque at motoring with fan disengaged (Nm)

MDfan_engage

measured engine torque at motoring with fan engaged (Nm)

nfan_engage

fan speed with fan engaged (min– 1)

nfan_disengage

fan speed with fan disengaged min– 1)

rfan

fan ratio

If the standard deviation of all calculated Ci at the three speeds npref, n95h and nhi is less than 3 %, an average value Cavg-fan determined over the three speeds npref, n95h and nhi shall be used for the fan constant.

If the standard deviation of all calculated Ci at the three speeds npref, n95h and nhi is equal or higher than 3 %, individual values determined for all engine speeds according to point (ix) shall be used for the fan constant Cind-fan,i. The value of the fan constant for the actual engine speed Cfan, shall be determined by linear interpolation between the individual values Cind-fan,i of the fan constant.

The engine torque for driving the fan shall be calculated according to the following equation:

Mfan = Cfan · nfan 2 · 10– 6

where:

Mfan

engine torque for driving fan (Nm)

Cfan

fan constant Cavg-fan or Cind-fan,i corresponding to nengine

The mechanical power consumed by the fan shall be calculated from the engine torque for driving the fan and the actual engine speed. Mechanical power and engine torque shall be taken into account in accordance with paragraph 3.1.2.

2.   Electric components/equipment

The electric power supplied externally to electric engine components shall be measured. This measured value shall be corrected to mechanical power by dividing it by a generic efficiency value of 0,65. This mechanical power and the corresponding engine torque shall be taken into account in accordance with paragraph 3.1.2.
