The project is about comparing the ethanol blends with neat gasoline. The purpose of the study is to compare the performance of the engine prior to the usage of neat gasoline and ethanol blends. A study of Alvydas Pikunas et. a!. however shown that there is possibility of engine performance increment due to the properties of the ethanol in the blends. The method used in the study is to test the fuels by using the engine test bench available in the university. The scope of the study is the performance parameter such as power curve, torque curve, and specific fuel consumption using ethanol-gasoline blends of 5% ethanol content to 20% ethanol content. The study shows that there is slight reduction of engine performance and increment in fuel consumption in all range of engine speed.
