Abstract

A control unit according to the present invention performs an automatic stop control in which an injection of fuel from a fuel injection valve is stopped to stop a rotation of an engine when an automatic stop condition is satisfied. Furthermore, the control unit performs a first injection, in which fuel is injected from the fuel injection valve of a cylinder in an expansion stroke, and an ignition operation for igniting the fuel injected by the first injection, when a restart demand occurs after an initiation of the automatic stop control. In addition, the control unit performs a second injection, in which fuel is injected from the fuel injection valve of a cylinder in a compression stroke, and an ignition operation for igniting the fuel injected by the second injection. Then, the control unit performs a third injection, in which fuel is injected from the fuel injection valve of a cylinder in a compression stroke, when it judges that a start-up failure for which a crank angle of the cylinder which is in the compression stroke after the second injection cannot get over the compression top dead center occurs or will occur.
