摘　　要：为了适应未来的排放法规和改善发动机的性能,考虑采用共轨式电控喷油系统以提高柴油机整体性能、降低排放污染。针对市场上某主流型号低速船舶柴油机,利用流体动力学仿真软件对该机型的中压共轨式喷油系统与两级阀式喷油器建立仿真模型,分析并总结系统中的关键参数对燃油喷射特性的影响。To meet the future emissions regulation and improve diesel engine performance, the common-rail system is applied to improve the diesel performance and reduce the diesel emissions. Taking the mainstream types of low-speed diesel engines in the market, the simulation models for the medium-pressure common-rail fuel injection system and the injector with two-stage valve are established by means of a fluid simulation software, and the influence of several key parameters upon the injection feature are analyzed and summed up for the system.
