Abstract
There is provided a configuration in which a cylinder which is in an inlet stroke when an internal combustion engine is in a stop (automatic stop) state is determined and stored, and when starting the engine upon detection of a start request, the fuel injection of an initial cycle to the cylinder, which has been determined as having been stopped in the inlet stroke when the engine was in the stop state before starting, is split into a plurality if injections at least including an injection before engine rotation, to thereby perform injections. As a result, startability is improved while suppressing pre-ignition at the time of starting.
