Experiment study on control methods of common rail pressure by entering flow

In this paper, the control methods of common rail pressure by regulating rate of entering flow are studied. The control circuit and solenoid valve are Trial-manufactured. The pressure of common rail controlled by Trial-manufactured solenoid valve are tested in test-bed. The results show that The opening time of Trial-manufactured solenoid valve is 1.1ms, and its closing time is 0.9ms. it can satisfy the requires of common rail system.
