Performance and Emission Characteristics of a Four Stoke Diesel Engine Operated by Neem Biodiesel Blended with Diesel

Industrialization and motorization of the world has led to a steep rise in the demand for petroleum products and other side the fast depletion of fossil fuel reserves and issues like global warming have led the researchers all over the world to search for an alternative fuels. Omong various options one of the best alternative fuel is Biodiesels obtained from Vegetable oils. The present study focuses on Evaluation of performance and emission characteristics of a single cylinder four stroke diesel engine with different blends (B05, B10, B15, B20 and B25 in comparison to diesel) of Neem biodiesel and Diesel. The performance is compared with diesel fuel, on the basis of brake specific fuel consumption, brake thermal efficiency, exhaust gas temperature and emissions of hydrocarbons and oxides of nitrogen. From the experimental Results it is observed that the neem biodiesel blend B20 have closer performance to diesel and hydrocarbon and carbon monoxide emissions are less than diesel.
