摘　　要：本文分析了高压共轨系统中喷油器电磁阀的驱动特性,对电磁阀驱动电路的工作原理进行了详尽的阐述。针对量产时PCBA喷油器模块的检测手段,通过对喷油器工作波形的处理,可以实现测试工装内部MCU的读取和判定。通过实验验证,可以实现对PCBA喷油器模块的筛选。The driving characteristic of injector solenoid valve which is a component of high-pressure common-rail fuel injection system is analyzed in this paper. The working principle of the solenoid valve boost circuit is expounded in detail.In order to detect the injector module in PCBA during mass production,the reading and determining of the internal MCU of the test tooling can be realized by processing the working waveform of the injector.Through the experimental verification, the injector module ofPCBA can be screened.
