【摘要】 研究了直喷柴油机燃用不同掺混比的LPG/柴油混合燃料时的动力性、经济性及排放特性。结果表明 ,掺入一定比例的LPG可以改善缸内燃烧过程 ,随着掺混比的增大 ,碳烟和NOX 的排放大幅度降低 ,CO和HC的排放略有升高 ,动力性和经济性基本维持不变更多还原

【Abstract】 The investigation of power performance;fuel consumption and characteristics of exhaust emission from the direct injection engine fueled with blend fuel with different proportion of LPG to diesel has been carried out.The test results show that the combustion process can be improved by fueling blend fuel with different proportion of LPG.When more amount of LPG adds to diesel fuel,the smoke and NO X emissions greatly decrease,the CO and HC emissions slightly increase,but the power performance and fuel consumption are the same as those of a diesel engine.更多还原
