Abstract
Disclosed is a control device of an engineincluding an injector. The injector has a needle which is displaced between a close position where no fuel is allowed to flow into a sac portion and an open position where the fuel is allowed to flow into the sac portion. The control device has a fuel injection controller controlling a fuel injection period and an injector controller controlling a motion of the needle. The injector controller executes control to reduce a moving speed of the needle before the needle reaches the closed position when the injection period ends.
