For a fuel economy, LPG fuel used to alternative fuel of gasoline engine. Driving condition of LPG engine is different front that of gasoline engine, because of chemical and pysical property.
In this paper, studied the movement for brake horse power, engine torque, fuel consumption and CO-HC emission of LPG fuel engine according to variation of ignition timing.
As results of study, following items were obtained;
1. Engine brake horse power and engine torque of L.PG fuel engine decrease according to ignition timing retard but by more advancing than gasoline engine ignition timing those were increased.
2. Specific fuel ensumption of LPG fuel engine decrease according to advancing more than 25 degree.
3. CO and HC emission of LPG fuel engine increase more than those of gasoline fuel engine.
