ABSTRACT:
A control apparatus for a cylinder-injection spark-ignition internal combustion engine, having a fuel injection valve for directly injecting fuel to a combustion chamber and controlling the fuel injection valve on the basis of either an intake stroke injection mode for effecting fuel injection mainly in the intake stroke and a compression stroke injection mode for effecting fuel injection mainly in the compression stroke. A fuel injection quantity correction device corrects at least the fuel injection quantity supplied to the combustion chamber and an intake air quantity correction device corrects the intake air quantity supplied to the combustion chamber so that the preset target idle speed is reached when an idle operation state is detected. An idle speed control device controls the idle speed on the basis of each correction amount corrected by the fuel injection quantity correction device and intake air quantity correction device when an idle operation state is detected and the compression stroke injection mode is selected.
