Abstract
In this paper we present the results of the measurements and analysis of particulate emissions of vehicles using the conversion system to use both LPG and gasoline fuels. The vehicles (n = 10) were measured using two different methods at the idle mode. The results show that the total number of particles from LPG-fueled vehicles is 1-1.35 times higher than gasoline-fueled vehicles for both PM2,5 and PM10 in most cases. An increase of the metal components in PM of LPG-fueled vehicles compared to gasoline-fueled vehicles, which might be related to lubricant was observed.
