摘　　要：应用Monte Carlo法与喷射系统液力仿真相结合的方法,对电控单体泵油量一致性影响因素进行了分析与研究,发现电磁阀阀芯孔直径和电磁阀阀芯行程的影响度最大,为电控单体泵油量一致性改进提供了理论依据。With the Monte Carlo and hydraulic simulation method, the influencing factors of fuel supply uniformity for electronic unit pump（EUP） were analyzed and researched. The results show that the orifice diameter and lift of solenoid valve are the most important influencing factors, which provide theoretical references for improving the fuel supply uniformity of EUP.
