India is one of the major countries facing vehicle pollution problems and spending most of its foreign currency on import of diesel products. In 1973, the oil crisis was started and depletion of ozone layer emphasized the necessity of alternative fuels. The Diesel Engines are dominating in transportation and agricultural machinery due to its fuel economy and cost effectiveness. The recent survey reveals that the diesel fuel consumption is several times higher than that of gasoline fuel. The Experimentation is going on jatropha oil and its blends with diesel which reduces the imports of petroleum products and expenditure of foreign currency. The direct use of these oils without any modification in diesel engines leads to poor performance and causes key damages on the parts of the engine. The Jathropa oil and vegetable biodiesel were blended with petroleum diesel in various proportions to evaluate and compared the performance and emission characteristics of a single cylinder direct injection constant speed diesel engine. The Diesel and Jathropa oil and vegetable biodiesel (10%, 20%, 30%, 40%, 50% and 60%) fuel blends were used to conduct engine performance and emission tests at varying loads. In this research work, the Jatropha and Diesel were tested in a single cylinder four stroke diesel engine and compared the results. The fire point of jatropha oil is more than that of diesel so this is very safe for transportation and storage and also the performance of engine with Jatropha oil is almost similar to that of diesel oil.
