摘　　要：以某款喷油器为研究对象,基于Abaqus对其密封性进行计算分析,结果表明其密封性薄弱部位为孔板密封面.通过增大控制阀座拧紧力矩和改进孔板结构2种方式,提高电控高压喷油器孔板接触面的密封性能.Taking an injector as the research object, Abaqus is used to analyze its sealing performance. The results show that the weakest sealing position is the surface of orifice plate. By increasing the tightening torque of valve seat and improving the structure of orifice plate, the sealing performance of the injector is improved.
