Abstract

We are using the available non-renewable resources at a rate that surpasses its rate of replenishment. So we need to efficiently use the fuels available and extract maximum energy from it. Using fuel mixtures of appropriate compositions mixed by volume/ mass called the flexible fuel mixture is a step to improve the fuel efficiency and engine performance parameters. Fanhua ma et al [1] studied the performance of an engine powered by mixture of CNG and hydrogen and results show that parameters such as brake thermal efficiency, brake specific fuel consumption depend on the ratio in which these fuels are mixed. Gasoline is widely used fuel for SI engines. Nowadays gasoline is blended with ethanol and this mixture is used as fuel for engines. In this research work, the performance of a 4stroke variable speed IC engine running on different combinations of Gasoline and Ethanol at different speeds and loads is analysed and the effect of fuel mixtures on power output of engine and fuel efficiency is checked and improved.
