摘　　要：以喷油孔积碳的康明斯B系列共轨柴油发动机为例,根据喷油孔积碳的成分和含量得出5组喷出油雾油束贯穿距L和油束锥角具体数值。将5组数据和标准数据进行数理统计和离散分析,得出每种积碳对发动机动力性能的影响。Taking Cummins B series common-rail diesel engine with fuel orifice carbon injection as an example,we obtain five group data of the oil mist penetrating distance L and oil beam angle according to composition and content of fuel orifice carbon accumulation.The data are compared with the normal one using mathematical statistics and discrete analysis to study the influence of each carbon deposition on the dynamic performance the engine.

关 键 词：积碳 燃油添加剂 油雾贯穿距 油束锥角 发动机性能
