A pulse electromagnetic control valve and its intelligent driver for electronically controlled diesel injection system are introduced. Based on the experimental research on the dynamic electromagnetic characteristics of the pulse electromagnetic control valve, the magnetic response time of the electromagnetic valve is reduced by improving the magnetic material used for the magnetic conductor, thereby greatly improving the quick response performance of the electromagnetic control valve. The intelligent driver adopts active high-frequency pulse width modulation to realize the intelligent control of the pulse electromagnetic valve driving energy injection mode and ensure the pulse electromagnetic control valve to work accurately and reliably in the electronically controlled diesel injection system. The second-order current differential signal feedback electromagnetism Close the starting point of the control valve, to achieve precise control of injection timing.
