The investigation of the effect of engine fuels constitute an important issue in an internal engine research due to deterioration and the sharp rise of conventional fossil fuels those creating the effect on a performance of engine, economy as well as the environmental pollution created by conventional fossil fuels. As the major contributor for fuel consumptions are automotive sector and in this the internal combustion engine plays a major role as power source prime movers. In this present

From this analysis, it is found that the brake power decreases for LPG fuel than that of gasoline fuel approximately 6% on higher side, volumetric efficiency and mechanical efficiency are lower down for LPG fuel. Internal combustion engines are seen every day in automobiles, trucks, and buses. The name internal combustion refers also to gas turbines except that the name is usually applied to reciprocating internal combustion engines like the ones found in everyday automobil power from chemical energy contained in the fuel. During this conversion, further loss as frictional loss reduced the brake power for the engine, so this energy should be converted reduction of engine mechanical friction always enhance the performance, increases the engine life and efficiency .It is the fact that large percentage of mechanical friction loss in engine is generated the piston cylinder assemblies as a rubbing friction.

As the utor for fuel consumptions are automotive sector and in this the internal combustion engine plays a major role as power source prime movers. In this present ignition engine with frictional power losses in a four stroke four cylinder petrol engine with bifuel mode of operation are carried out with both the fuel with required modification on four stroke four cylinder spark ignition engine at various load and variable speed conditio power are found out along with the various performance parameters. From this analysis, it is found that the brake power decreases for LPG fuel than that of gasoline fuel approximately 6% on higher side, volumetric efficiency and mechanical efficiency are lower down for LPG fuel.
