摘　　要：利用AMESim软件建立了某柴油机电控组合泵燃油喷射系统仿真模型.通过喷油特性实验验证模型准确性后,仿真分析了喷孔直径、凸轮型线速度和柱塞直径等主要因素对喷射性能影响规律;并通过正交实验设计,开展了燃油喷射系统结构参数优化匹配分析,得到了两组优化的结构参数方案,即喷油器孔径0.24 mm,凸轮型线速度0.46 mm/(°AC)、柱塞直径15 mm和喷油器孔径0.26 mm,凸轮型线速度0.46 mm/(°AC),柱塞直径15 mm两组,为燃油喷射系统的匹配设计提供参考.A simulation model of an electronic control assembly pump system of adiesel engine was es- tablished on AMESim, the accuracy was verified with the experimental data of fuel injection characteristics. Subsequently, the fuel injection performance influenced by structural parameters （fuel injector aperture, cam profile velocity and plunger diameter ） was analyzed on simulation. Besides, the structural parameters matched and optimized on fuel injection system were studied, and two structural parameter optimization pro- jects were achieved, namely, fuel injector aperture 0. 24ram, cam profile velocity 0. 46m/ （ °AC） , plunger diameter 15mm and fuel injector aperture 0.26mm, cam profile velocity 0. 46m/ （°AC） , plunger diameter 15ram, which can provide reference for matching design of electronic-controlled assembly pump system.
