Abstract  

In order to shorten hardware system development cycles and reduce development costs, a precise circuit model for the driving module of solenoid valve for common rail injection system was created. The impact of different driving voltages on the response time of actuators was analyzed based on the simulation results, and the circuit for shortening the close delay was realized. Based on a comprehensive analysis of the simulation results on the condition of different parameters, two driving voltage sources with 110 V and 24 V were adopted in different driving stages, hold current was feedback controlled by hardware pulse width modulation (PWM) signal, and fault detecting and diagnosing circuits were designed. The experimental results show that the open delay and close delay of the injector are shortened; the boost voltage is stable during the injection process; and the reliability of the design approach for common rail injection system is proved．

基于电路仿真的高压共轨电磁阀驱动电路设计

为了缩短硬件系统的开发周期及降低开发成本,利用电路仿真软件建立精确的柴油机高压共轨喷油器电磁阀驱动电路模型.基于仿真结果分析不同驱动电压对电磁阀电流提升响应时间的影响,并设计减少其关闭响应时间的电路.在对各个因素综合分析的基础上,设计高低双电源（110 V和24 V）驱动及硬件脉宽调制（PWM）的维持电流反馈控制喷油器电磁阀驱动模块,以及电磁阀驱动回路的故障检测电路.试验结果表明,优化后的驱动模块显著缩短了喷油器电磁阀的开启延迟和关闭延迟,驱动高压在燃油喷射过程中基本保持稳定,同时证明了采用该设计方法设计高压共轨电磁阀驱动模块是切实可行且高效可靠的.
