In an automobile the power developed basically depends upon the fuel used for combustion. Gasoline and Diesel are used in liquid form which is extensively used in the world from last century. These fuels are obtained from crude oil reserves, which is available in limited quantity in the world. This situation will create a problem for energy crises in the future. The fossil fuels are also the big source of air pollution which is having a negative impact on environment as well as on human health.In the present scenario, ethanol is being used as an additive with gasoline in many of the countries of the world. At present in India, 10 percent ethanol mixing with gasoline is mandatory by the Government of India and from the year of 2017, it will be 20 percent. From the past researches it has been found that ethanol is a good replacement of gasoline but is has many disadvantages like: - due to its hygroscopic nature, ethanol damages the internal part to the engine, it effects the metallic as well as non-metallic part of the engine. For overcoming the problems an effort has been made in this study by using butanol as an additive with ethanol gasoline blends because butanol is not hygroscopic in nature and does not rust the internal parts of the engines.In this report, performance analysis of multi cylinder spark ignition engine has been evaluated on ethanol gasoline blend with or without butanol addition. Ethanol was added with gasoline in three different volumetric ratio as 10,20 and 30 percent. Butanol was added in the volumetric ratios of 2.5,5,7.5 and 10 percent with ethanol gasoline and gasoline. Various performance parameters of the engine such as bsfc. BTE, BSEC and EGT have been observed. Exhaust emission such as carbon monoxide, hydrocarbon and oxides of nitrogen has also been observed. The results show that addition of butanol in ethanol gasoline blends had positive effect on the engine performance. Emissions of CO and HC founds to be lower compared to ethanol gasoline blends and gasoline. While NOX emission were on higher side. Overall, additive blends have been performed well and found suitable without any hardware modification of the engine.
