Experimental Investigation of Performance Characteristic of Diesel Engine Run on Calophyllum Inophyllum Biodiesel 5% Blend

An increasing demand of fossil fuels has being a critical problem for us. The natural resources of fossil fuel are dwindling day by day. Biodiesel that may call natural fuel may be a good source or substitute for fossil fuel in future. Biodiesel can be produced from vegetable oils and also from waste fats. Biodiesel is a mono-alkyl-ester of long chain fatty acids derived from renewable feedstock such as vegetable oils by transesterification process. The esterifies cotton seed oil, pungam oil, rice bran oil, and Calophyllum Inophyllum oil are chosen as the alternative fuels. Among these oils, Calophyllum Inophyllum oil is considered as an alternative fuel. An experiment is conducted to obtain the performance characteristics of the diesel engine run by chosen esterifies oils, and the results are compared with esterifies Calophyllum Inophyllum oil. From the comparison of results, it is inferred that the engine performance is nearly matches the diesel fuel without any engine modification. The experimental results obtained in the engine run on 5% biodiesel blend of Calophyllum Inophyllum oil is a promising alternative fuel for direct-injection four-stroke diesel engine.
