Experimental Analysis on Performance and Emission Characteristics of C.I. Engine Fueled by Neem Oil Biodiesel with Additive

In this present work, experiments were conducted on a VCR Diesel engine with diesel, Neem oil biodiesel and Di-ethyl ether mixed with neem oil biodiesel. The performance and emission characteristics were evaluated and compared. The study shown that the Brake thermal efficiency increased and the brake specific fuel consumption reduced with B10 blend of neem oil biodiesel compared to diesel. The emissions of CO, CO2 were reduced but HC and smoke were increased with the use of biodiesel than diesel. The addition of Diethyl Ether (DEE) further improved the performance and decreased the emissions of CO and CO2 of the engine at B20DEE20 blend compared to other blends of biodiesel and diesel.
