Abstract:
A solution to eliminate the life failure of an engine solenoid valve is introduced in this paper. The reason that the armature in solenoid valve gets stuck is analyzed. The cause of the failure is that the armature in the bushing of the valve gets a non-uniform force, which results in the roll-torque and violently local friction in movement process. The improvement scheme and test results of solenoid valve are presented in this paper.
