On an average 95% of energy requirements all over the world are derived from conventional energy sources such as coal, natural gas and Petroleum. It is estimated that these reserves are not going to last for not more than 50 years. Hence comes the problem of energy crisis. In this context of fossil fuel crisis, the importance of alternative fuel research for Internal. Combustion engines needs importance. Vegetable oils – due to their properties being close to diesel fuel, may be a promising alternative for its use in diesel engines. Bio-diesel is non-toxic, biodegradable and renewable fuel with the potential to reduce engine exhaust emissions.

           The idea deals with the usage of raw Jatropha curcas oil as well as blends of varying proportions of Jatropha Methyl Ester (JME) and Diesel in a single cylinder diesel engine with and without thermal barrier coated piston. Significant improvements in engine performance and emission characteristics were observed for JME. The use of JME along with diesel fuel has significantly reduced HC and CO emissions and to reduce NOx emissions Hybrid fuel concept is followed.
