An evaluation was undertaken of seven LP gas powered, standard sized American cars. The cars were equipped with V-8 engines, automatic transmissions and Algas Industries dual fuel carburetion systems. Each car was tested according to the proposed 1972 Federal procedure, which includes a cold start, the LA4-S3 driving schedule, and emission sampling by the CVS method. Results from these tests are presented for each car as mass emissions. The cars were then taken through a hot-start two-cycle test according to the 1970 Federal procedure, with the CVS method being employed in addition to the continuous sampling. Data from these two hot seven mode cycles are presented as (1) concentrations and mass emissions as calculated by the 1970 procedure, and (2) mass emissions calculated from the CVS procedure. The results are presented and discussed.
