An evaluation of the emission characteristics of two vehicles equipped with compressed natural gas conversions was made. The vehicles evaluated were a six cylinder Chevrolet and a four door Ford pickup truck, both of which used dual fuel conversions with modified Impco fuel systems, and both of which were capable of being driven on either gasoline or compressed natural gas. Two different driving cycles were used in the evaluation of these vehicles. In the first tests nine cycles of the seven mode 1970 Federal emission test driving schedule were used. For the other tests, the 1972 test procedure for certification of new vehicles was used. The tabulated results indicated the following conclusions: (1) the level of emission of the vehicles tested are below 1972 standards; (2) the level of emission of the vehicles tested are below the proposed 1975 standards.
