Title:
DEVICE FOR CONTROLLING SOLENOID VALVE
Document Type and Number:
Japanese Patent JP2019100220
Kind Code:
A
Abstract:
To solve such the problem that a capacitor of a booster circuit is not charged completely in time and an applied voltage to a solenoid valve decreases, and which may cause variation in injection amount under a split injection condition of performing injection multiple times in one combustion cycle.SOLUTION: A control device includes a low voltage source and a high voltage source and charges a capacitor of a booster circuit for boosting a voltage for the high voltage source that feeds a solenoid valve at a high voltage, thereby including a function for early restoration of a voltage for the booster circuit.SELECTED DRAWING: Figure 6
