Analysis of Influence factors of Opening Response Time of High-pressure solenoid valve

In order to improve the opening response time of the solenoid valve of a certain marine diesel engine, this paper analyzes the influence on the opening response time of the solenoid valve based on ANSOFT software. The results show that the opening response time of the solenoid valve can be appropriately shortened by increasing the voltage and reducing the working gap, but it still can not meet the 10ms requirement of opening time. However, the opening response time of the solenoid valve can be significantly shortened by optimizing the coil parameters under certain conditions of the solenoid valve structure parameters. Finally, a quarter coil is used to shorten the opening response time of the solenoid valve from 27.4ms to 9.2ms shortened by 66.4%, which meets the requirement of the opening response time of the solenoid of a marine diesel engine.
