Abstract
In this paper, a high response, greater flow and higher pressure solenoid valve is developed. The valve's dynamic electromagnetic characteristics are analyzed by experiments. The fast response of the valve is obtained by material and structural modifications. The lifetime of solenoids may be extended. By analyzing and calculating with finite element method, the magnetic core's structural parameters and the magnetic coil parameters are optimized. The power control and drive method are discussed. The energy consumption is decreased. A method is provided for demagnetizing the magnetic core to release the valve core. So that the response time of solenoid are further shortened. The test results proved that the solenoid valve developed in this paper is of a maximum flow of about 35l/min, 100bar pressure dispersion and 0.89ms respond time. By using this valve, injection quality hopes to be improved and the exhaust emission hope to be decreased. The key difficult problem in diesel engine electronic control may be solvable.
