Abstract
An injection control device includes an injector and a detection unit. The injector includes: an injection hole; a movable part; a seat portion; a valve housing; a magnetic field application unit; and a detection sensor. The movable part opens and closes the injection hole by reciprocal movement. The seat portion when seated by the movable part closes the injection hole, and when the movable part lifted therefrom opens the injection hole. The valve housing accommodates the movable part in a reciprocally movable manner. The magnetic field application unit is installed on an outer circumference of the valve housing and applies a magnetic field to the movable part and the valve housing. The detection sensor outputs a detection signal according to a size of a distance between the valve housing and the movable part.
