Proposal for an amendment to Regulation No. 49
11 May 2012 Informal Group Informal Documents Diesel and CNG/LNG Engine Emissions Diesel/CNG/LNG Engine Emissions Uniform provisions concerning the measures to be taken against the emission of gaseous and particulate pollutants from compression-ignition engines and positive ignition engines for use in vehicles 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 Consolidated proposal from the GFV Task Force on Heavy-duty Dual-fuel vehicles for an amendment to Regulation No. 49 in view of type-approving such vehicles. GFV-20-0002/a
GFV-20-03
Proposal for amendments to Regulation No. 83 (CLEPA)
11 May 2012 Informal Group Informal Documents Motor Vehicle Emissions Motor Vehicle Emissions Uniform Provisions Concerning the Approval of Vehicles with regard to the Emission of Pollutants According to Engine Fuel Requirements The proposed amendments are aimed at redefining the class of bi-fuel vehicles to permit the simultaneous use of gas and petrol in gas mode. This submission follows the review by CLEPA members of the draft proposal (GRPE/2012/6). GFV-20-0003

Input for a revision of the THC and methane (CH4) emission limits of NG vehicles (CLEPA)
11 May 2012 Informal Group Informal Documents The current Euro 6 light duty vehicle emission limits for total hydrocarbons (THC) include the methane fraction as well as non-methane hydrocarbon emissions. When the Euro 5/6 co-decision proposal was negotiated, an NMHC limit value was added but the THC limit was unchanged and is too restrictive. GFV-20-0004

UN R115 and R83: Correction Factor for G-25 Weighting Process (AEB Tech and Landi Renzo)
01 Jun 2012 Informal Group Informal Documents Motor Vehicle Emissions Motor Vehicle Emissions Uniform Provisions Concerning the Approval of Vehicles with regard to the Emission of Pollutants According to Engine Fuel Requirements Liquefied Petroleum and Compressed Natural Gas Retrofit Systems LPG/CNG Retrofit Systems Uniform Provisions Concerning the Approval of: I Specific LPG (Liquefied Petroleum Gases) Retrofit Systems to be Installed in Motor Vehicles for the Use of LPG in their propulsion system II. Specific CNG (Compressed Natural Gas) Retrofit Systems to be Installed in Motor Vehicles for the Use of CNG in their propulsion system Documents GRPE/2012/6 and 7 introduce the calculation of NG/biomethane energy ratio during a type I cycle by weighing the NG/biomethane mass consumed. The formulas are affected by an error when G25 reference fuel is used. This proposal precribes a modification to the previous formulas. GFV-20-0005

01 Jun 2012 Informal Group Informal Documents Compressed and Liquefied Natural Gas System Components CNG/LNG System Components Uniform Provisions Concerning the Approval of: I. Specific components of motor vehicles using compressed natural gas (CNG) and/or liquefied natural gas (LNG) in their propulsion system; II. Vehicles with regard to the installation of specific components of an approved type for the use of compressed natural gas (CNG) and/or liquefied natural gas (LNG) in their propulsion system. Progress report of the LNG Task Force created to develop technical specifications for LNG (Liquefied Natural Gas) cryogenic components to be installed on-board road vehicles. GFV-20-0006
