摘　　要：根据不同启喷压力下柴油机喷油特性的仿真计算,分析不同启喷压力下喷油特性的变化规律,设计出一种可变启喷压力的喷油器,在柴油机处于不同工况的情况下,可以改变喷油器的启喷压力,使柴油机燃烧特性得到改善.Based on the simulative calculation on the diesel engine＇s injection characteristics in different fuel starting injection pressure,this paper analyses the variation rules of inject characteristics.A structure of diesel injector is designed.The fuel starting injection pressure can be changed when the diesel engine is in different working modes,so that the combustion characteristics of diesel engine can be improved.

关 键 词：启喷压力 喷油特性 喷油器
