N2 - Opening and closing process of high pressure common rail injector are affected directly by dynamic response characteristics of solenoid valve. In order to research the dynamic response characteristics of solenoid valve, experimental investigation was first conducted on the drive current and the power source voltage. Relationships between flux linkage and drive current of solenoid valve under different air gaps were acquired from the experimental results according to the principle of drive circuit. Electromagnetic model of the solenoid valve was built based on the relationships acquired. Then dynamic model of armature was built according to the working principle of solenoid valve. Finally, electromechanical model of the solenoid valve consisting of electromagnetic model and dynamic model was built and simulated in Matlab/Simulink. Special experiment was designed to verify the electromechanical model. Simulation and experiment results showed a good agreement with each other.
