Evaluation of DI Diesel Engine Performance on Biodiesel from Waste Cooking Oil at Different Load Conditions

Biodiesel is more attractive than petroleum diesel because of its environmental benefits and the reality that it is made from renewable resources and has lower emissions. Present research work deals in the preparation of biodiesel from waste cooking oil, obtained from KC College of Engineering and IT, Nawanshahr, Punjab messes. The performance of a direct injection (DI) diesel engine has also been carried out when fuelled with blends of Diesel-biodiesel, biodiesel-ethanol and diesel-ethanolethyl acetate over the entire range of load on the engine. The experimental results showed that the highest brake thermal efficiency (BTE) 31.12% was observed for D80/E13/EA7 at full load i.e. 7.26% higher than from D100 (28.86%). The higher BSFC for B100 (262.4 g/kWh) is about 14.9 % higher than diesel (223.2 g/kWh) at full load.
