【摘要】 生物柴油是一种清洁、可再生的代用燃料.在一台四缸增压直喷式柴油机上进行生物柴油与0#柴油的性能对比试验.在不同转速和负荷下测定生物柴油与0#柴油的动力性、经济性和排放特性.试验结果表明:与燃用0#柴油相比,燃用生物柴油时发动机的动力性提高,有效能耗率降低,HC和碳烟排放大幅度下降,NOX排放增加,CO排放在中低转速时有所增大.更多还原

【Abstract】 Biodiesel is a kind of clean and renewable alternative fuel.In this study,a comparative test of biodiesel and No.0 diesel has been carried out on a supercharged direct injection diesel engine.Under different loads and speeds,this paper determines power performance,fuel consumption and characteristics of exhaust emission from the engine fueled with biodiesel and No.0 diesel.The results show that,comparing with burning No.0 diesel,when the engine fuels with biodiesel,its power is increased,its effective specific fuel consumption is reduced,the HC and smoke emissions greatly decrease,but the NOX emissions increase and the CO emissions increase under some conditions.更多还原
