The depletion of oil resource as well as the environmental regulation has led to the development of alternate energy sources. In present work the performance characteristics of a computerized single cylinder diesel engine when fuelled with blends of mustard, kerosene and diesel were evaluated. Experiments were performed with different blends namely MK5, MK10 and MK15and the performance of these blends was compared with diesel oil. The various fuel properties such as Calorific value, viscosity, flash point, fire point, carbon residue and cetane number were calculated in Anacon Laboratories Pvt. Ltd, New Delhi for different blends. For analysing the performance of C.I. engine using these blends- brake power, mechanical efficiency, brake mean effective pressure, brake thermal efficiency, specific fuel consumption, torque and volumetric efficiency were found at different load. Variations of cylinder pressure with crank angle were observed at loads of 15kg, 9kg and in no load condition. Brake thermal efficiency for MK5 blend was greater as compared to diesel fuel and other blends and was least for MK15 blend. The specific fuel consumption was found minimum for MK5 blend as compared to diesel fuel and the other blends. And specific fuel consumption was maximum for MK10 blend. The volumetric efficiency reduces with increase in load and was greater for MK5 blends as compared to other blends, although it was quite less than that of diesel oil. It was found that the blends of Mustard, kerosene and diesel oil could be successfully used with acceptable performance up to certain extents in C.I. engine.
