Performance study of di diesel engines by using pure mustard oil as an alternative fuel for diesel engine at various load condition

Energy is indispensable for modern civilization. Fossil fuel is still the main source of energy but the huge consumption of fossil fuel has brought its reserve about to an end. As a result, fuel prices are gouging as a consequence of spiralling demand and diminishing supply. So, it’s an important challenge to search alternative and cost effective fuels, to meet the demand. Diesel engines are more efficient and cost-effective than other engines. Vegetable oils can be used in the diesel engine by pure form or by trans-esterified form. In this paper pure mustard oil blending with diesel at different proportion like M20, M30, M40, M50 and M100 (pure mustard) has been used in different load condition in 4 stroke single cylinder diesel engine mounted on a hydraulic dynamometer bed. Physical properties of different blend like heating value, density, viscosity, flash point and fire point has been determined before performance test of the engine. The engine data was taken applying load from 6 kg to 15 kg at constant rpm 2000. M20 and M30 have the bsfc 272.98 gm/kw-hr at 9.00 kg load & 288.03 gm/kw-hr at the same load condition. From this work, it has been found that M20 shows better performance than other blends and pure mustard. © 2014 The Authors. Published by Elsevier Ltd.
