UN R143: Proposal for a Supplement 1 to the original version
Reference Number: WP.29/2017/66
Proposal to restrict the application of CO2 specific emission limits only to NMHC and CO emissions (back-to-back comparison of NOx and PM to apply under the regulation in any case). The proposal also aligns the text where applicable with the intent of paragraph 2.3.15.: “R49 original emission limits” means the emission limits as defined in Regulation No. 49 to which the original engine system was approved."
This proposal (WP.29/2017/66) was adopted by the World Forum. Thirty-nine Contracting Parties out of the 52 applying UN R143 were present for the vote by AC.1. Thirty-nine voted in favor with zero against and zero abstaining.
