Impact of Biofuel in Petrol Engine-A Review

Abstract

This review paper represents the recent development done in four stroke petrol engine using various blend of petrol and biofuel. Engine performance is increased by using ethanol as a blended fuel. Oxygen containing additives, such as methanol, ethanol, methyl tertiary butyl ether (MTBE) and diethyl carbonate (DMC), are used to improve engine performance. This review paper also present the experimental studies of engine performance and exhaust emission by using ethanol as a blended fuel in different ratio. With the help of these studies we observe that the mixture of ethanol and gasoline provide less ozone depletion potential and global warming potential than the pure gasoline. The mixture of ethanol and gasoline are best alternative fuel for spark ignition engine compare to other biofuel mixture.
