Analysis of Higher Alcohol Fuel Blends for IC Engine—A Review

Abstract

Higher alcohols like propanol and butanol have some significant advantages over lower alcohols like Methanol and Ethanol. Higher alcohols in engine resting better engine performance due to their lower heating value. The blending of Propanol and butanol is between the ratio of 5–20% with petrol and diesel in SI and CI engines also reduces the various emissions which effect the environment and improves spray characteristics. Butanol is thus not only a promising alternative fuel for gasoline but also a possible replacement for bioethanol as a fuel for internal combustion engines for transportation. There is a lack of literature review study on using higher alcohols like propanol and butanol with different blend ratios with diesel and petrol. The main objective of this paper is to analyze the performance of an IC engine using higher alcohols and its blend as a fuel. The study in this review papers to find out effect on engine parameters and various exhaust emission at different blends ratio. This review paper will help in critical areas to address research gaps on higher alcohols as a fuel in the IC engine.
