1. India proposals on part B1 & B2 text

2. Proposal 1: 4.2 "Unladen mass" (mk) means the nominal mass of a complete vehicle as determined by the following criteria: Mass of the vehicle with bodywork and all factory fitted equipment, electrical and auxiliary equipment for normal operation of vehicle, including liquids, tools, fire extinguisher, standard spare parts, chocks and spare wheel, if fitted. The fuel tank shall be filled to at least 90 per cent of rated capacity and the other liquid containing systems to 100 per cent of the capacity specified by the manufacturer Sum of unladen vehicle mass and driver’s mass. The driver’s mass is applied in accordance with paragraph 4.4. below. Explanation: India proposes to delete the red text. Editorial change.

3. Proposal 2: 4.38 ‘Pollution-control device’ means those components of a vehicle that control or reduce tailpipe and/or evaporative emissions; Explanation: India proposes to add the definition.

4. Proposal 3: EPPR-21-20 clause no 6.3
Temperature shall be measured in °C. Wherever temperature conversion is required in K for calculation purpose, the following equivalence shall be used, 0 °C = K.
Note for Technical report on temperature conversion:
After deliberation in EPPR-IWG it was referred by chair to WLTP also during 75th GRPE session and finally it was agreed that wherever temperature conversion is required from deg C to K following conversion factor to be used 0 deg C= K

5. Proposal 4: EPPR-21-20 part B1, Clause no 7
Proposal 4: EPPR part B1, Clause no 7.2 Table B1-6: Need to cover DF factor * **
Note:* DF for PI engined vehicles for CO is 1.3, THC is 1.3, NMHC is 1.3 , NOx is 1.3 and PM is 1.0.
**DF for CI engined vehicles for CO is 1.3, THC is 1.1, NMHC is 1.1 , NOx is 1.1 and PM is 1.0.
Explanation: The values of DF has been added in principal norm as per EU Regulation, mentioned in blue colour

6. Limits (mg/km) for PI Engines
Proposal 5: EPPR part B1, Clause no 7.3 ,Table B1-7
Alternate performance requirement:
This requirement is only for PI engines

Notes:
(1) For BS-IV, there is an option to comply with evaporative emission norm of 6g/test (instead of 2g/test) HC+NOx norms to be tighten by 200mg/km from the values given in table.
(2) Applicable parts of driving cycle for BS-IV are part 1 RS cold and part 1 RS hot, as against Euro 4, part 1 RS cold and part 2 RS hot.
(3) BS-IV limits have DF already built-in (DF for CO is 1.2 , NOx is 1.2 & HC+NOx is 1.2).
(4) Euro 4 limits are without DF (DF values for CO is 1.3, HC is 1.2 & NOx is 1.2).

7. Part B2

8. Proposal 6: Document No. EPPR-21-22, Clause no. 3.4.5.1.2.
India proposal on testing in other than predominant mode
In addition to testing in predominant mode, based on the information provided by the manufacturer on different operating modes, the test agency will test a vehicle in a selected mode(s) after discussion and mutual agreement between test agency.
Explanation :
India proposes to carry out tests on predominant mode primarily and in those cases where multi modes are present, based on the information provided and mutual agreement, additional mode (s) may or may not be selected for testing.

9. Proposal 7: Soak Room temperature: No of times India has explained about the soak room temperature
To bring uniformity wrt to GTR 15 for WLTP. This is to reduce the infra and operating costs of testing;
All types of vehicles are running in the same environment and they shall be tested in similar reference conditions. This is also applicable for test room temperature and humidity. It was also informed to the EPPR members that this point was deliberated at length in WLTP before arriving at this decision.
Considering the higher level technologies and more stringent limits the temperature range needs to be optimized in line with WLTP to reduce the variability in the test results.

10. Proposal 8: EPPR-21-22, Part B2 clause no 4.2.2.2.5
Chassis dynamometer with polygonal function
In the case of a chassis dynamometer with polygonal function, in which the absorption characteristics are determined by load values at several specified vehicle speed points, at least five three specified vehicle speeds, including the reference vehicle speed, shall be chosen as the setting points. At each setting point, the chassis dynamometer shall be set to the value Fpau (vj) obtained in point
Explanation:
To improve the accuracy of road load simulation, India proposes to have atleast five points.
