Complementary specifications, as adopted by the gaseous fueled vehicles informal group at its 19th session, to UN R49: Revision 6/06 series of amendments) in order to enable the type approval of new EURO VI heavy duty dual-fuel engines and vehicles.

Comments from Poland on the Gaseous Fueled Vehicles (GFV) informal group proposal to redefine the class of bi-fuel vehicles under UN R83 in order to permit the simultaneous use of gas and petrol while in gas mode.

Comments from Poland on the Gaseous Fueled Vehicles (GFV) informal group proposal to redefine the class of bi-fuel vehicles under UN R115 in order to permit the simultaneous use of gas and petrol while in gas mode.

Draft agenda for the joint meeting of the Informal Group on Gaseous Fuel Vehicles
and its Heavy Duty Dual-Fuel Task Force.

GFV overview of existing emission definitions applicable to light and heavy duty vehicles in EU and UNECE legislation, including certain definitions currently (February 2012) under discussion, in order to identify possible inconsistencies.

Proposal from the GFV informal group concerning definitions for mono-fuel and bi-fuel vehicles, for engine start-up in petrol mode, and provisions for petrol direct-injection engines under UN R115.

GFV informal group input for a revision of the THC and methane (CH4) emission limits for vehicles equipped with engines running on natural gas (Euro 6 Light Duty Vehicles and Euro VI Heavy Duty Engines).

Minutes of the meeting of the Informal Group on Gaseous Fuel Vehicles held jointly with the Heavy Duty Dual-Fuel Task Force.

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).

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.

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.
