Biodiesel refers to a vegetable oil- or animal fat-based diesel fuel consisting of long chain alkyl (methyl, propyl or ethyl) esters. Biodiesel is typically made by chemically reacting lipids with an alcohol. Biodiesel is meant to be used in standard diesel engines and is thus distinct from the vegetable oils. Biodiesel can be used alone, or blended with diesel. Biodiesel, a promising substitute as an alternative fuel has gained significant attention due to the predicted shortness of conventional fuels and environmental concern. The utilization of liquid fuels such as biodiesel produced from Jatropha oil by transesterification process represents one of the most promising options for the use of conventional fossil fuels. The production of biodiesel is limited by land area but jatropha trees can be cultivated in any kinds of land.Jatropha is a wildly growing hardy plant, in arid and semi-arid regions of the country on degraded soils having low fertility and moisture. It can be cultivated successfully in the regions of heavy rainfall even it can be cultivated even on fallow and barren lands. Jatropha vegetable oil is one ofthe main non edible sources available in India. In view of the above, a study was carried out with the following objectives:Production of Jatropha oil ethyl ester or Jatropha oil biodiesel by two step esterification process, Determination of characteristic fuel properties of different blends of Jatropha oil ethyl ester , Di ethyl ether and diesel BDE1,BDE2,BDE3 AND B100 AND DIESEL. And Performance evaluation of a CI engine on blended fuels. After the investigation the results we found that The density of B100used in the experiment was 7.69 % higher than the diesel .The viscosity of Jatropha biodiesel was about 35% higher than the diesel.The gross heat of combustion of raw neem oil is found to be 2.61% lower than the diesel.The performance evaluation of 4.4 kW diesel engine under the fuel consumption test on blends of Jatropha,DEE and diesel was found satisfactory on the basis of brake power, brake specific fuel consumption and brake thermal efficiency.The engine was able to develop power similar to diesel on all the Jatropha- DEE- diesel blends.The brake thermal efficiency of the engine on BDE2 was found higher than diesel on lower load .The engine performance was the best on BDE2 as the brake thermal efficiency was found to be high at lower load and overall BTE of BDE3 was highest and BSFC was found to be second lowest on BDE2 blend as BSFC was lowest on BDE1
