1泵喷射系统的组成对现代柴油机的动力性、经济性、排放率和噪声级的要求一直在提高,这就要求燃油喷射系统能产生足够高的喷射压力,确保燃油雾化良好,同时对喷油始点与
1 The composition of the pump injection system has been increasing the demands on the dynamic, economical, emission and noise level of modern diesel engines. This requires that the fuel injection system can generate a high enough injection pressure to ensure that the fuel atomizes well while spraying Oil starting point and
