【摘要】 本文介绍了作者在一台４９２Ｑ型汽油机上进行燃烧沉积物对发动机性能影响的研究结果，发现燃烧沉积物导致发动机压缩比提高，废气排放中ＮＯｘ、ＨＣ排放增多并导致发动机充气效率下降，此外还分析了燃烧沉积物形响发动机性能的主要原因。更多还原

【Abstract】 In this paper, effects of combustion deposits on engine performance are investigated in a 492Q spark ignition engine. The investigation shows that combustion deposits result in increase of compression ratio and NOx、HC emissions and decrease of volumetric efficiency. In addition, the main reasons for effects of combustion deposits on engine performance are analyzed更多还原
