PERFORMANCE ANALYSIS OF SMALL SIZE (BELOW 100CC) ENGINE WITH SUPERCHARGER USING GASOLINE ETHANOL BLEND

There are many inventions aimed at increasing the performance of IC engines. In general, practical engines are always compromised by trade-offs between different properties such as efficiency, weight, power, heat, response, exhaust emissions, or noise. When power increases efficiency is always decreases. Presently, ethanol is prospective material for use in automobiles as an alternative to petroleum based fuels. The main reason for advocating ethanol is that it can be manufactured from natural products or waste materials, compared with gasoline, which is produced from non-renewable natural resources. Some methods and components are useful for increasing performance of engine. One such method is the use of supercharger in I.C. Engine. It is known that the power outputs of an engine increases with the increase in amount of air or mixture in the cylinder and supercharger plays an important role in increasing the amount or air. Till now supercharger is being successfully employed in heavy engines but its use with smaller engine is still under development. Thus this project employing a supercharger in small engine with capacity of nearly 100cc which used in two wheeler bike. In recent years, the motor vehicle industry aims at the small sized and high power density engine, while downsizing (small size and weight saving) and measuring the improvement in fuel consumption, and cleanization. Full power is needed only for accelerating and hill-climbing; during the remainder of the time the excess.
