Session 77 | Geneva | 4-8 Jun 2018
5. Regulations Nos. 85, 115, 133, and 143

GRPE may wish to consider a proposal prepared by the expert from the International Organization of Motor Vehicle Manufacturers (OICA) to align the provisions of the 03 series of amendments to UN Regulation No. 24 with UN Regulation No. 85.

GRPE-77-20 | UN R24: Justification for alignment with UN R85 Explanation of the proposal (GRPE/2018/19) to align UN R24 (Compression Ignition Engines – Emission of Visible Pollutants – Power Measurement) with UN R85 with regard to correction factors.
GRPE/2018/19 | UN R24: Proposal for amendments Proposal to align UN R24 (Compression Ignition Engines – Emission of Visible Pollutants – Power Measurement) with UN R85 with regard to correction factors.

GRPE may wish to consider a proposal tabled by the expert from Italy and interested experts on the need to introduce a reference to WLTP instead of emission tests performed on the basis of the former test cycle (New European Driving Cycle (NEDC)).

GRPE-77-06 | UN R85: Amendment proposal Proposal to introduce an alternative test method for measuring charge-air-cooled engines net power for use with high power engines of those. The proposal would “decrease the charge air cooler outlet temperature by the same amount that the ambient conditions for the vehicle test varied from the standard temperature” in line with SAE J1349, “9.3 Application of Vehicle Transient Data to Net Power Test.”
GRPE-77-09 | UN R115: Proposal for amendments This document addresses the need to align Regulation No.115 to the new WLTC test cycle, defined in the GTR 15 and in the Commission Regulation (EU) 2017/1151 and later modifications.
GRPE-77-23 | UN R115: AEGPL position on document GRPE-77-09 AEGPL views on the proposal to align Regulation No.115 to the new WLTC test cycle, defined in the GTR 15 and in the Commission Regulation (EU) 2017/1151 and later modifications.
