Working Party | Informal | Heavy-Duty Dual Fuel Retrofit Systems HD Dual Fuel Retrofit Systems Uniform provisions concerning the approval of Heavy Duty Dual-Fuel Engine Retrofit Systems (HDDF-ERS) to be installed on heavy duty diesel engines and vehicles | 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." |
