Title:
燃料噴射装置の駆動装置
Document Type and Number:
Japanese Patent JP6670893
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To suppress performance necessary for a calculation load or pressure sensor of a drive device, and also detect variation in injection amount of a fuel injection device of each cylinder to correct the variation in injection amount.SOLUTION: A drive device of a fuel injection device is configured to drive a movable valve to inject a predetermined amount of fuel, by flowing current for an electrification time to make it reach flowing current, the electrification time set for each solenoid of a plurality of fuel injection devices configured to open/close a fuel flow passage. The drive device is characterized by correcting the set electrification time or flowing current, based on a pressure detection value from a pressure sensor, which is attached to a fuel pipe on an upstream side of the plurality of fuel injection devices.SELECTED DRAWING: Figure 10
