摘要：

This paper investigates performance and emission characteristics of a single cylinder diesel engine which is fuelled with different blends of walnut oil biodiesel and diesel. Crude walnut oil was converted into walnut oil methyl ester by alkaline-catalyzed transesterification process. Various proportions of walnut oil biodiesel and Diesel are prepared on volume basis, and physically-chemically characterized. Engine performance (brake specific fuel consumption, brake thermal efficiency, and exhaust gas temperature) and emissions (HC, CO, CO2 and NOx) were measured at five engine loads. The results obtained showed an increase in BSFC and EGT and a decrease in BTE for all biodiesel blends. The emissions showed that biodiesel leads to a reduction of CO by 61.53% and HC by 30.3% and an increase of CO2 by 5.11% and NOx by 14.68%. Therefore it is concluded from the present experimental study that biodiesel of walnut can be used as alternative fuel for diesel engines.
