利用仿真软件GT-Suite建立电控单体泵燃油喷射系统仿真模型，通过实验验证仿真模型的准确性。改变电控单体泵喷油器结构参数，包括高压油管长度，高压油管直径以及喷孔数量进行仿真计算。根据高压油管长度和直径9组参数组合对压力波影响，选取最佳油管长度和直径。在此基础上，验证3组不同喷孔数目对压力波的影响，选择最合适的喷孔数。结果表明，通过仿真分系统结构参数对喷油系统压力波动的影响，可以为电控单体泵燃油喷射系统的优化设计提供有效依据。

GT-Suit software is used to establish the electronic unit pump system model. The accuracy of the simulation model is verified by the experiment. The simulation calculation was conducted by changing the structure parameters of electronic unit pump system, such as the number of the nozzle, the length of the high-pressure oil pipe and the diameter of the high-pressure oil pipe. According to the results of simulation model, the paper discusses the influence of the structural parameters of injector on electronic unit pump system. This research offers the valid basis for the optimization design of Electronic unit pump system.
