Abstract
An object of the invention is to provide a drive device of a fuel injection device which can increase the accuracy in an injected fuel injection amount by combining the fuel injections from a plurality of injection pulse widths. In the drive device of the fuel injection device which has a function of driving the fuel injection device such that the fuel injection is performed plural times in one combustion cycle, the fuel injection device is driven such that a fuel injection at a target opening level in which a valve element or a movable element of the fuel injection device reaches a regulation member and a fuel injection at an intermediate opening level in which the valve element does not reach the regulation member are included in the plural times of division injections performed in one combustion cycle.
