ABSTRACT:
An injection quantity control unit controls an injection quantity of a plurality of fuel injection valves, respectively. The unit includes a rotational speed obtaining device for obtaining a rotational speed of the engine, an integration value calculating device for calculating an integration value of the rotational speed, which is equal to or more than a predetermined rotational speed, in an explosion stroke of each of the cylinders, and a correcting device for correcting the injection quantity of the plurality of fuel injection valves based on the integration value of each of the cylinders so as to reduce variation in a rotational speed variation among the cylinders.
