【摘要】 通过在R4105T柴油机上进行对比试验,分析了0#柴油/生物柴油、乙醇/生物柴油混合燃料以不同比例掺混时对柴油机动力性、经济性及碳烟排放特性的影响。研究结果表明:柴油机使用0#柴油/生物柴油混合燃料时动力性、碳烟排放量均有所下降,油耗率稍有上升;使用乙醇/生物柴油混合燃料时,碳烟排放量低于生物柴油,动力性、经济性随乙醇含量的不同而呈现不同的变化趋势。更多还原

【Abstract】 This paper studies the dynamic,economic and smoke performances of biodiesel blended fuel with contrast test on R4105T diesel engine,in which biodiesel is mixed with diesel and ethanol separately at a different ratio.The result shows that dynamic and smoke performance of diesel engine decreases when the engine fuels diesel and biodiesel blended fuel while oil consumption rate rises a little.Compared to the engine burning the pure bio-diesel,smoke performances of diesel engine decreases when it runs with ethanol and bio-diesel blended fuel,but dynamic and economic performances tends to change with different ratio of ethanol in blended fuel.更多还原
