Performance Evaluation of CI Engine on Fuel Blends of Neem Oil Biodiesel and Diesel
In the present study, biodiesel is produced from neem oil by two step esterification process. The neem oil ethyl ester (NOEE) diesel blends are prepared by blending 10 to 100% NOEE with diesel. The blends containing 10 to 100% ester have their kinematic viscosity, cloud and pour point and flash and fire point compatible with diesel. The performance test of 4.4 kW diesel engine on fuel blends of neem oil biodiesel and diesel has carried out in terms of brake power, fuel consumption, brake specific fuel consumption (BSFC) and brake thermal efficiency. Brake power of all the blends was found comparable with diesel, whereas fuel consumption, BSFC and brake thermal efficiency of 100% NOEE were found higher than the diesel. NOEE20 as fuel the brake thermal efficiency is found to be highest, and BSFC was found to be lowest on this blend. NOEE100 could be used as fuel with some modification in engine. Performance of NOEE20 is better than other blend so it could be used as future fuel.
