Revised proposal, superseding document GRPE/2018/5, to clarify the wording of the determination of the net power for electric motors and to correct an error in the formula presented in paragraph 5.4.2. Diesel engines – Factor αd. The parameter “f_m” in the equation should be a superscript (e.g., meaning “to the power of f_m”). Through a transcription error, this factor was rendered in normal text.

OICA proposal to explore the possibilities for harmonizing RDE procedures adopted around the world.

Revised proposal for Amendment 4 to GTR 15 from the WLTP informal group.

Revised proposal from the WLTP informal group pursuant to GRPE-76 discussions for Amendment 4 under the Phase 2 development of GTR 15.

Proposal to align UN R24 (Compression Ignition Engines – Emission of Visible Pollutants – Power Measurement) with UN R85 with regard to correction factors.

OICA request for clarification over whether the test results should reflect the energy (fuel and electric energy) used for vehicle propulsion or the energy used for vehicle propulsion and for energy conversion (recharging the battery – fuel energy to electric energy).

OICA proposal to pursue gradual harmonization of heavy-duty vehicle fuel efficiency standards, beginning with an effort to define a uniform measurement procedure through a global technical regulation.

Proposal of amendments to:

1. align the definitions for bi-fuel vehicles align with the new definitions in UN GTR 15,
2. amend paragraph 5.3.1.2.4. to recognize that particulate pollutant emissions measurements are no longer limited to compression ignition vehicles,
3. amend paragraph 7.4.4.3. of Annex 7 to correct a typographical error,
4. amend paragraph 3.2.1.of Annex 8 to correct an error originating with UN R83 Revision 3 (2005),
5. amend paragraph 6.5.3.5. to correct a cross-reference error introduced in Amendment 1 (reference should read para. 6.5.3.3. rather than 6.5.3.2.) and should refer to the “annex” rather than the “appendix”.

Updated proposal to adapt the 06 and 07 series of amendments to Regulation No. 83 to Selective Catalytic Reduction (SCR) warning and inducement systems to current vehicles, emissions requirements and reagent infrastructure. In light of further vehicle weight reduction for CO2 optimization and the resultant use of smaller AdBlue® reagent tanks, this proposal would allow for reagent refill inducement warnings as a percentage of tank capacity or as a function of the average driving range with a complete tank of fuel.
