Short summary
In this study, the effectiveness of a LPG converter replacement program was evaluated. It was found that LPG-related VOCs and NOx decreased significantly due to the implementation of the program. Source apportionment also revealed the reduction of VOCs and NOx in LPG-fueled vehicle exhaust. From before to during the program, O3 increased slightly, mainly due to the reduction of NOx in LPG-fueled vehicle exhaust. To retain zero O3 increment, the lowest reduction ratio of VOCs / NOx was determined.
In this study, the effectiveness of a LPG converter replacement program was evaluated. It was...
