摘要： Because the relationship of the fuel injection quantity to a designated injection period differs in a half-lift region and a full-lift region, the purpose of the present invention is to bring the flow rate characteristics of an intermediate-lift region close to the flow rate characteristics of the full-lift region and improve the controllability of small fuel injection quantities. Provided are a peak current supply period in which a valve body of a fuel injection valve causes the magnetic force necessary for a valve-opening action to be generated, and a lift quantity adjustment period in which, after the peak current supply period, a current lower than the peak current is passed for a prescribed period; further provided is a current interrupt period in which a drive current is rapidly lowered before the lift quantity adjustment period.

摘要： Provided is a control device of an internal combustion engine, said control device enabling a required air/fuel ratio to be satisfied with high accuracy. For each first period, a calculation unit calculates (500) the number of fuel injections within one combustion cycle and the fuel injection rate, which indicates the rate of fuel injections within one combustion cycle. With respect to the first period, a first storage unit stores (500) the number of fuel injections and the fuel injection rate calculated by the calculation unit. For each second period, which is different from the first period, a reference unit refers (506) to the number of fuel injections and the fuel injection rate stored by the first storage unit. A second storage unit stores (506), with respect to an interval from the start time of the first fuel injection (512) until the start time of the last fuel injection (513) of at least one combustion cycle, the number of fuel injections and the fuel injection rate referred to by the reference unit. A control unit controls a fuel injection valve in a manner such that fuel is injected in accordance with the number of fuel injections and the fuel injection rate stored by the second storage unit.
