Abstract

The exploration for alternative fuels was prompted by increasing environmental concerns, rising conventional fuel prices and fossil fuel depletion. The improved potential of waste cooking oil makes it desirable for its utilization for biodiesel production. In the present study, enzymatic transesterification of waste cooking oil (WCO) is done using lipase enzyme to produce waste cooking oil methyl ester (WCOME) and three different test blends were used namely, Diesel+20% of WCOME, Diesel+40% of WCOME, and Diesel+60% of WCOME. After several trials the optimum reaction factors found to be methanol as the alcohol, 1.5% enzyme concentration (by weight of WCO), 3:1 M ratio and 4 h reaction time. The performance and engine characteristics like as brake specific fuel consumption, brake thermal efficiency, and the emissions of CO, HC, and NOx were analyzed in unmodified compression ignition engine. Test results revealed that the blend with lower biodiesel content performed well in the engine with lowered CO, HC and NOx emissions. But with the higher biodiesel concentrations, there was a considerable increase in the emission spectrum. Overall, Diesel+20% of WCOME and diesel+40% of WCOME blends resulted in improved performance with minimized emissions and can be utilized in an unmodified DI diesel engine.
