This is a revised version of the proposal by the Gaseous Fueled Vehicles (GFV) informal group 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.
This proposal was prepared by the experts from the International Organization of Motor Vehicle Manufacturers (OICA) in order to incorporate the content of Regulation (EU) 566/2011 into UN Regulation No. 83.06.
