Alternative fuels become important as the increasing price and demand of the limited reserves of the petroleum products, and these conventional fuels are responsible for environmental pollution and global warming. Alcohols like ethanol and methanol are good alternative fuels, ethanol and methanol has high octane no and ethanol has anti-knocking properties. This review discusses the effect of alcoholic blended fuels on the performance and exhaust emission of spark ignition engines. Ethanol and methanol reduces the CO and unburned HC in the exhaust emissions. This review also discusses effect of compression ratios on the performance and exhaust of the spark ignition engine with different blended fuel. Break thermal efficiency (BTE) and volumetric efficiency of SI engine increases as the compression ratio of ethanol and methanol blended fuel increases.
