摘要： 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.

摘要： The present invention relates to an apparatus for and a method of controlling a variable valve timing mechanism. The valve timing mechanism changes over between a first cam for which the closing timing IVC of the intake valve is after intake bottom dead center, and a second cam for which the closing timing IVC is closer to intake bottom dead center than the closing timing IVC with the first cam. Here at the time of stopping the internal combustion engine, the valve timing mechanism changes over to the first cam, and the initial intake stroke performs operation at low effective compression ratio. In the second and subsequent intake strokes, the valve timing mechanism changes from the first cam to the second cam.

摘要： A control apparatus for an internal combustion engine where the inside of a combustion chamber is divided into a layer of internal EGR gas and a combustible layer to perform stratified combustion. In a port-injected engine equipped with first and second intake valves, the opening timing of the first intake valve is set before a top dead center (TDC) and the opening timing of the second intake valve is set after the TDC, and the closing timings of the first intake valve and the second intake valve are set after a bottom dead center. Then, fuel injection toward the first intake valve is started after the EGR gas, which was blown back to the intake port upstream of the first intake valve, is drawn into the combustion chamber after the top dead center.
