Title:
SOLENOID VALVE CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/107125
Kind Code:
A1
Abstract:
The present invention addresses the problem of a case where variation in the injection amount is generated, by the voltage that is applied to a solenoid valve being reduced where charging of a capacitor of a booster circuit is not completed in time in a condition of split injection in which injection is performed a plurality of times during one combustion cycle. Provided is a control device of the present invention for solving the above-mentioned problem, comprising: a low voltage source and a high voltage source, wherein the control device has a function of accelerating voltage recovery of the booster circuit by charging the capacitor of the booster circuit that boosts the high voltage source that is applied to the solenoid valve with high pressure.
