Theoretical and Experimental Research on the Polluting Emissions for an Middle Class Vehicle Equipped with Engine that Uses the Double Energy Source, Gasoline and LPG

Considering the severe conditions for reducing the chemical pollution caused by the vehicles imposed by regulations and rules worldwide, the liquefied petroleum gas becomes an attractive alternative fuel from an ecological and economical point of view. At present, there is almost no car manufacturer that does not include in the fabrication scheme spark ignition engines that use LPG as an alternative source of energy knowing the benefits of the GPL in terms of reducing pollutant emissions.
