Energy security and global warming concern are the two main driving forces for the global alcohol development that also has the effort to animate the agro-industry. Generally, alcohol and ether fuels are produced from several sources and can be produced locally. Nearly all alcohol fuels have comparable characteristics of combustion and ignition to existing known mineral fuels. In order to increase the amount of octane and oxygen content of gasoline, ether fuels (MTBE and DME) are primarily used as additives at low blending ratios.The addition of alcohol and ether fuels to gasoline lead to a complete combustion due to the higher oxygen content, thereby leads to increasedcombustion efficiency and decreased engine emissions. The goal of this paper is to systematically investigate the use of alcohols and ethers such as butanol, methanol, ethanol, fusel oil, MTBE, and DME as SI engine fuels. The performance effects (brake torque, and efficiency emissions (CO, CO2, NOx and HC).The increase in engine performance could be attained with an increased compression ratio along with the use of alcohol fuels which have a higher-octane value. Furthermore, alcohol and ether burn very cleanly than regular gasoline and produce lesser carbon monoxide (CO) and nitrogen oxide (NOx) (NOx). On the other hand, the energy content of alcohol and ether fuels is roughly 30 percent lower than that of gasoline, thus raising the real fuel consumption (SFC) when alcohol and ether are used as fuel at the same time.Finally, this paper also discusses the impacts of alcohol on engine vibration, engine noise, and potential to be used as a gasoline octane enhancer. Alcohol can be used as a pure fuel in spark ignition engine, but it requires some modifications to the engine.
