A Review on Effect of Blends of Higer Alcohol on Emission of Si Engine

Abstract

The world in the 21st century presents many critical challenges. One of the most important challenges is the environment. As population increases and the standard of living improve, there is a growing concern that there will be a shortage of energy to heat our homes and power the vehicles on which we so heavily depend. We must also remember the need for clean air, clean water, cleaner burning fuels, and biodegradable, renewable materials. Advances in technology have allowed development of alternative energy sources. Alternative energy sources are renewable, cleaner, and more dependable than traditional fuels.Presently ethanol is found to be best alternative fuel blended with gasoline. Many researches have been made on higher alcohol blend with petrol which can reduce the emissions characteristics of SI engine. The objective of this paper is to provide a thorough literature review on the current status of higher alcohol blends on emission in SI engine and to guide the continuity study of reduction emission using higher alcohol blends with petrol.
