Internal Combustion Engine, Gasoline,, Ethanol,

February 2018

Gasoline and Diesel are basic in liquid form which are extensively used in the world from last century. Presently in India, 10 percent ethanol blending with gasoline is mandatory by the Government of India and from the year of 2017, it will be 20 percent. It has been found that ethanol is a good replacement of gasoline but is has some disadvantages. Due to its hygroscopic nature, ethanol damages the internal part to the engine. It affects the metallic as well as non-metallic part of the engine. For overcoming this problem 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 study, performance and emission characteristics of a 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. Performance parameters of the engine such as bsfc. BTE, BSEC and EGT have been observed. Overall, additive blends have performed well and found suitable without any hardware modification of the engine.
