FUEL INJECTION DEVICE DRIVE DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a fuel injection device drive device capable of improving accuracy of an injection amount of a fuel to be injected by a combination of a plurality of types of fuel injection different in injection pulse width.SOLUTION: A fuel injection device drive device that functions to drive a fuel injection device so as to inject a fuel at a plurality of divided timing in one combustion cycle, drives the fuel injection device so that types of fuel injection include fuel injection at a target opening degree at which a valve element or a need of the fuel injection device reaches a restriction unit and fuel injection at an intermediate opening degree at which the valve element does not reach the restriction unit.
