Solenoid Valve Control for Diesel Engines fuel Pump

디젤엔진 연료펌프의 솔레노이드 밸드 PWM 제어

This paper describes an study electric injection system for diesel engines. It is needed effective fuel injection which controls the solenoid valve of fuel pump. To solve this, this paper proposes DCC-PWM method which can realize fast reply and low holding current for solenoid valve on/off. For the proposed design method, simulation tools of ACSL are used to analyze the system. And the single-chip microcomputer is used to reduce the size of controller and to improve flexibility. And the system's validity can be verified through the experimental results.
