Internal combustion engine running on Liquefied Petroleum Gas are well proven technologies and work much like gasoline- powered spark ignition engine. This is normally used in spark ignition engine for bi-fueled petrol and LPG vehicles. Increasing focus on liquid petroleum gas (LPG) as clean, relatively low in cost and abundant source of energy to provide affordable fuel-efficient transportation, needs research for optimization approach to manage fuel, air, and combustion to achieve best result in vehicle power, fuel efficiency and low emissions. However power output of LPG fueled engine is reduced by 10-15% compared to petrol fuel. In this study, exhaustive literature survey is carried out and experimental setup is discussed for further investigation. Basic task is to evaluate effect of LPG on various performance parameter of the engine with brake, indicated and friction power, thermal efficiencies, fuel consumption, volumetric efficiencies. Existing multi-cylinder petrol engine is modified for required set up in which Morse test, heat balance sheet and engine oils are also to be analyzed for tribological behavior of engine.
