Proposal as endorsed by GRPE for a new Consolidated Resolution concerning Exhaust Ultra-Fine Particle Number Measurement For Heavy Duty Engines.

Text as approved by GRPE to introduce a modified WMTC test cycle procedure and a new vehicle classification for low-powered vehicles, such as commonly used in India and China.

Proposal for new Consolidated Resolution concerning Exhaust Ultra-Fine Particle Number Measurement For Heavy Duty Engines. The document is also available with tracked changes in pdf format and in docx format.

Proposal to correct the recursive formula of the 05, 06 and 07 series of amendments to UN Regulation No. 83 in the procedure for verifying the conformity of production requirements if the production standard deviation given by the manufacturer is either not satisfactory or not available.

Proposal to permit use of equipment conforming to UN R154 for testing under UN R83 (and by extension to UN R101 which references UN R83).

Proposal to clarify the scope of Regulation 85 concerning electric drivetrains.

Proposal to correct the recursive formula in the procedure for verifying the conformity of production requirements if the production standard deviation given by the manufacturer is either not satisfactory or not available.

Proposal to harmonize:

• Requirements for the determination of CO2, fuel and electric energy consumption of the discharge requirement for OVC-HEV with an operating mode switch with its stop criterion.
• Preconditioning requirement (Annex 9, determination of electric range) and UN R83 (Annex 14, provisions for emissions test procedures for HEV).

Annex 4A-Type 1 tests include references to daytime running lamps and rear position and other lamps. In line with UN R48 and its 08 series of amendments which would permit switching off of rear position and other lamps when ambient light conditions are above 7,000 lux to avoid unnecessary fuel consumption, this proposal would permit ambient lighting during dynamometer operation above this threshold.

Annex 5 procedures include references to daytime running lamps and rear position and other lamps. In line with UN R48 and its 08 series of amendments which would permit switching off of rear position and other lamps when ambient light conditions are above 7,000 lux to avoid unnecessary fuel consumption, this proposal would permit ambient lighting during dynamometer operation above this threshold.

Annex B6 procedures include references to rear position and other lamps. In line with UN R48 and its 08 series of amendments which would permit switching off of rear position and other lamps when ambient light conditions are above 7,000 lux to avoid unnecessary fuel consumption, this proposal would permit ambient lighting during dynamometer operation above this threshold.

The use of test fuels is permitted for certification testing of gaseous and particulate pollutants and power/smoke testing in Europe. However, other countries that have adopted and referenced UN R24 may not allow this. This proposal would permit the use of the same test fuel in cases where the testing for emission of gaseous and particulate pollutants is conducted at the same time as the testing under UN R24.

Proposal to introduce provisions specific to special-purpose vehicles.

Proposal to introduce provisions for the approval of a vehicle type with an approved engine with regard to their emission of pollutants, and the reporting of the CO2 emissions and fuel consumption for type approval of vehicles with a reference mass exceeding 2,380 kg but not exceeding 2,610 kg.

Proposal to align UN R24 with to align the UN R85 and ISO 1585:2020.

Proposal to align UN R85 with ISO 1585:2020.

Proposal to expand the scope to include more vehicle types (higher-powered three-wheeled vehicles) and to introduce additional fuel types to be included in the test procedure.
