Biodiesel Preparation from Neem Oil and Performance on Its Blend

This research dealt with the preparation of neem oil Biodiesel. This paper mainly include two-step transterification. The transterification process turns neem oil into methyl esters. The notable properties of the biodiesel like flashpoint, viscosity, calorific value, density are compared with the diesel. The consistency (viscosity) of biodiesel oil is closer to diesel and the calorific value is about 15% less than diesel. This thesis supports the Neem oil biodiesel prime production of neem oil and then studying engine performance using the biodiesel blends mix with diesel. A four stroke engine (single-cylinder) was taken to measure performance parameters. Biodiesel added to the diesel at four variety of volume concentrations i.e. 10, 20, 30 and 40% of biodiesel. Based on the analysis of performance the biodiesel blend 20% (B20) was most optimum for the efficient operation of the engine.
