摘　　要：介绍了一种对不同电磁阀进行参数优选的方法,以保证高压共轨控制系统中电磁阀的快速开启、可靠吸合和快速关断。该方法通过在喷油泵试验台上测试喷油量,确定出电磁阀驱动电压、开启电流及维持电流参数,不需要考虑系统复杂的电、磁、液综合因素。应用该方法对某高压共轨部件高速电磁阀进行试验,优化出驱动参数,并在喷油泵试验台上进行了稳定性试验验证,结果表明该方法能够满足工程应用。A method of selecting parameter for different solenoid valves was introduced,to ensure the quick opening,reliable contacting and rapid turn-off of solenoid valve in the high-pressure common rail system.By measuring the injection quantity on the injection pump test bed,the parameters of driving voltage,open-current and holding current for solenoid valve were determined.In addition,the method did not need to consider the complicated electric,magnetic and liquid factors in the system.With the method,the high-speed solenoid valve of a high-pressure common rail system was tested.The driving parameters were acquired by the optimization and verified through the steady test in the injection pump test bed.The result shows that the method can meet the engineering application requirements.
