Performance Emissions and Combustion Analysis of CI Engine Using Ethyl Ester Kusum Oil and Butanol Blends 2019-01-0568

Globalization, urbanization and industrialization have paved the way for manufacturing activities and production, maintaining standards and competition which have eventually resulted in skyrocketing fuel prices, a drastic increase in carbon emissions as well as exhaustion of petroleum resources at an alarming level. Multiple researchers have therefore explored alternative fuels for diesel engines. Industries have time and again proven to develop technologies that have not only reduced the emissions produced in combustion engines but have also increased their efficiency, power and fuel economy.

Using alternative fuels can also aid in reducing air pollution. Biodiesel is an alternative, renewable and biodegradable fuel which can significantly reduce emissions in an automobile and push the economical, sustainable and smart growth of the country. Kusum (Schleichera oleosa) oil still has great potential which must be realized. In this paper, the research efforts are directed towards improving the performance of C.I. engine using ethyl ester Kusum oil (Vegetable oil) and butanol blended with diesel as a fuel. No modification in the engine was needed in order to use this blend. The performance of a single-cylinder, four stroke, Compression Ignition engine was studied using Kusum oil ethyl ester and its blend with diesel, having the engine being operated at various loading conditions with water cooling system. Four samples were prepared with 5%, 10%, 15% and 20% butanol in Kusum oil ethyl ester(v/v) and were named as B5KOEE95, B10KOEE90, B15KOEE85 and B20KOEE80. Engine performance factors namely BTE, BSFC and emissions of CO, CO2, unburnt HC, NO_x were measured and analyzed among diesel, KOEE100, B5KOEE95, B10KOEE90, B15KOEE85 and B20KOEE80.
