【発明の名称】電磁弁制御式燃料噴射装置での弁はね上がりの利用方法
Document Type and Number:
Japanese Patent JP2002516951
Kind Code:
A
Abstract:
A method of utilizing the first valve bounce is used in a diesel engine having a solenoid valve controlled fuel injection system, wherein the solenoid-actuated valve is movable between a fully closed position for injection and a fully open position preventing injection. The method includes: (1) energizing the solenoid for valve movement to the fully closed position for commencing pilot injection; (2) de-energizing the solenoid immediately prior to the valve reaching the fully closed position for pilot injection in order to facilitate movement of the valve toward the fully open position immediately after the valve has reached the fully closed position, thereby preventing subsequent valve bounces; and (3) re-energizing the solenoid immediately prior to the valve reaching the fully open position, whereby to facilitate movement of the valve toward the fully closed position for main injection immediately after the valve reaches the fully open position, thus preventing subsequent valve bounces and decreasing time lag between pilot and main injection.
