Abstract
Three LPG conversion systems were evaluated for Federal Test Procedure emissions and fuel economy on a 1992 Chevrolet Lumina. These three “kits” were tested using up to four different LPG fuel blends. Installation and adjustment problems of the conversions are discussed in this paper. Despite the variability of emissions between systems, the driveability was generally good and the reactivity of the hydrocarbon emissions, as shown by speciation, was low compared to the industry average gasoline baseline data. In fact, the reactivity adjustment factor (RAF) was as low as 0.292 for a conversion which met 1993 EPA standards.
