Provided is a control device of an engine that can certainly suppress and avoid pre-ignition. A control device of an engine is an engine control device for controlling the behavior of fuel that is directly injected into a combustion chamber of a cylinder by a tumble flow, and it has an injector that directly injects the fuel into the combustion chamber, an intake port that generates the tumble flow in the combustion chamber, and an ECU that injects the fuel from the injector at a plurality of injection timings including an intake-stroke-early-half injection timing that is set at an early half of the intake stroke of the cylinder, when an operating state of the engine is in a high-load, low-rotation range.
