Experimental Performance Evaluation on S.I. Engine with Gasoline and Liquefied Petroleum Gas as Fuel

Abstract

Energy Demand is increasing tremendously. Although fossil fuels have high calorific values but it makes a hazardous impact on the environment which leads to acid precipitation, ozone layer depletion, global climate change and global warming, so there is huge scope to use such fuels which reduce cones of fossil fuel. In the present study, a 150 cc I.C. Engine is used for experimentation which having four gears and coupled with rope type dynamometer. There are two testings performed with the same engine. The First test carried out with gasoline as a fuel and measured the emissions of carbon monoxide and Hydrocarbons along with break power against torque, second test with LPG to measure the same parameter as with gasoline thus made a comparison of various parameters for both the fuels. Engine runs on different gears to know the actual performance of engine on the road running at different gears since almost all vehicles having gearbox which provides appropriate speed and torque at appropriate gears and loading conditions.
