HIGHER ALCOHOL BLEND WITH PETROL: ALTERNATIVE FUEL FOR SI ENGINE A REVIEW

Mechanical Engineering

Internal combustion engine are the most preferred prime mover across the world. Spark ignition engine is preferred locomotive prime mover due to its smooth operation and low maintains. The gasoline is fossil fuel which is limited in reservoirs causes varieties of study in search of alternative fuel for SI engine, where alcohol promises best alternative fuel. Considering the energy crises and pollution problems today, investigations have concentrated on decreasing fuel consumption by using renewable alternative fuels and on lowering the concentration of toxic components in combustion product. An experimental investigation was conducted to determine the emission characteristics of higher alcohols and gasoline blends. While lower alcohols (methanol and ethanol) have been used in blends with gasoline, very little work has been reported on higher alcohols (propanol, butanol, and pentanol). The objective of this paper is to provide a thorough literature review on the current status of higher alcohol blends on performance characteristics and emission in SI engine and to guide the continuity study of improving performance characteristics and reduction emission using higher alcohol blends with petrol.
