Document Title Proposal for amendments to ECE/TRANS/WP.29/GRPE/2017/4 on Heavy Duty Dual-Fuel Engine Retrofit Systems
Reference Number GRPE-74-25
Date
13 Jan 2017
Summary 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."
