Performance of a Diesel Engine Run with Mustard-Kerosene Blends

Increasing oil prices and global warming activates the research and development of substitute energy resources to maintain economic development. The methyl esters of vegetable oil, known as biodiesel are becoming popular because of their low ecological effect and potential as a green substitute for compression ignition engine. 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 kerosene 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 engine testing. The engine data was taken applying load from 6 kg to 15 kg at constant rpm 2000. From this study we find that among, the blends m20 and m30 has the minimum bsfc 257.94 gm/kw-hr at 12.5 kg load & 269.67 gm/kw-hr at 12.5 kg load condition respectively Hence m20 can be considered as suitable blend for mustard blending with kerosene for diesel engine.
