This study present the influence of oxygenate additive DEE on entropy generation, exergy performance coefficient, emission, and performance characteristics of direct-injection (DI) diesel engine fuelled with WCO (waste cooking oil) biodiesel. Experiments are conducted at constant speed of 1600 rpm for full load condition. DEE is mixed with WCO biodiesel blend in the proportion of 5, 10, and 15%. Performance and exergy parameters for WCO biodiesel blend are compared with that of diesel fuel. It is found that addition of DEE enhance the engine performance effectively from the energy and exergy point of view. Reduction in NOx emission is also observed with the addition of DEE. The exergetic efficiency is increased by 8.5% for 15%DEE addition and NOx emission is reduced from 1900 ppm to 420 ppm with the addition of DEE. Lower entropy generation and improve exergy performance coefficient is also observed.
