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).

Documents GRPE-63-05/Rev.1 and GRPE/2012/6/Rev.1 propose to redefine the class of bi-fuel vehicles to permit the simultaneous use of gas and petrol in gas mode in UN Regulation No. 83. CLEPA proposes an alternative method to the weighing procedure of the fuel consumption test procedure.
