Abstract
A control device of the present invention is applied to an engine provided with a fuel injection valve which directly injects fuel into a combustion chamber. The control device includes a pre-ignition prediction unit which predicts occurrence of pre-ignition when the engine is started; and an injection control unit which causes fuel to be injected in an expansion stroke from the fuel injection valve when occurrence of pre-ignition is predicted by the pre-ignition prediction unit. Thus, it is possible to prevent pre-ignition without lowering the effective compression ratio.
