Abstract—The objective of this work is to check the performance characteristics of four stroke single cylinder diesel engine by using different blends of biodiesel. The two different seeds used are Jatropha and Pongamia mixed with diesel under different proportions. The blend ratios used for present study are B5, B10, B25 and B100. The tests were done for different blends to verify the properties like, Flash point, Fire point, Viscosity, and calorific value. Experimental results obtained from the work shows that thermal efficiency increases with increase in load with increase in blending ratio. It is finally concluded that use of biodiesel as a future fuel will be environment friendly but not cost effective.
