摘　　要：介绍了电磁喷油器的工作原理和流量特性。从电路、磁路、机械运动和流体运动等多角度建立了一个综合的计算模型。在此基础上开发出电磁喷油器的检测台,以检测喷油器的滴漏、喷油量、喷油角度、雾化程度、喷油均匀度;在各工作环境中的工作状态;进行全过程自动静态检测、动态检测和选择检测,能模拟发动机任意工况,真实观察到喷油器工作的全过程。该检测系统已投入使用,取得了良好效果。The injecting process and flow characteristics of electronic control injectors are analyzed in this paper, and a comprehensive computational model is set up from the viewpoints of electrical circuit, magnetic field, mechanical motion and fluid mechanics. The measuring apparatus can inspect the electronic control injector characteristics, for instance, the dropping leak characteristic, constant spray of fuel, the angle of the spray fuel, the degree of pulverization, the uniformity of the spray fuel, and it can simulate various working conditions. The measuring apparatus was successfully put into operation and achieved good effect.
