【摘要】 采用一台车用增压中冷直喷式发动机,燃用市售0号柴油和在其中加入0.12%某复合燃油添加剂的市售0号柴油,通过发动机台架试验,对0号柴油加剂前后发动机的动力性、经济性和排放特性进行对比分析。结果表明:在稳态试验工况下,加入该添加剂对柴油机性能影响不大;气态排放物有不同程度改善,柴油颗粒物排放减少效果显著;燃油经济性有适当改善,但效果不显著。更多还原

【Abstract】 commercially available 0#diesel and its mixture with 0.12%of a complex additive were fueled into a turbo-charged direct injection engine to carry out a bench test for an analytical comparison of power ability,fuel economy and emission characteristic of the diesel oil before and after modification by the additive.Under steady-state test conditions,the complex additive indicated no obvious effect on diesel engine power,but gaseous emission was somewhat improved,particles in exhaust gas were significantly reduced,and fuel economy was improved by a limited degree.更多还原
