Abstract— In the mechanized and the fast-moving world of today, the consumption of petroleum products has become an important yardstick of a country’s prosperity. Despite the discovery of new sources of non- conventional energy, petroleum remains the primary energy source all over the world. The consumption of petroleum in the world, which started at a few tonnes a year around 140 years ago, has reached over 3000 Million metric tons (MMT) per year. Even in India, it is increasing at a very steep rate from 3.5 MMT in 1950-1951 to 130 MMT in 2001-2002. This is expected to reach 175 MMT in 2006- 2007.

In the present work, Pongamia piñata oil is chosen as an alternative fuel to run an I.C engine. In this work, experimental investigations were carried out on a single cylinder, four-stroke water-cooled diesel engine coupled with rope dynamometer. The experiments were conducted for various combinations of Pumgamia piñata with diesel, by preheating Pumgamia piñata to an elevated temperature of 60°C. The performance analysis has been carried out and the various parameters like power output, BSFC, brake thermal efficiency were measured. The results compared with the baseline test on high speed diesel suggest that these oils can be successively used in the form of blends.
