Energy is a basic requirement for economic development and almost all petroleum product vitality utilization in the transportation division is from oil (97.6%), with a limited quantity from flammable gas.Karanja is medium sized tree and is found throughout India and can be a good alternative to the depleting fossil fuels. The tree is drought resistant. A thick yellow-orange to brown oil is extracted from its seeds and yields of 25% of volume are possible using a mechanical expeller. A single cylinder, four stroke, consistent speed, water cooled, direct infusion diesel engine put in NIT Kurukshetra was utilized for the investigations. The plans were made for preheating the fuel utilizing waste heat of fumes gases from the engine through heat exchanger. The experiments were conducted on some blends (K10, K20, K30, and K40) of diesel and Karanja oil at different loads. Graphs plotted between SFC (Specific Fuel Consumption) and BHP (Break Horse Power)helps to see the variation of specific fuel consumption with respect to BHP for diesel and the blends of Karanja oil. Hence, this study investigate the performance of diesel engine working on unheated and preheated Karanja oil blends with diesel and compare them that of diesel oil.
