Abstract
A combustion control apparatus is configured for a direct-injection spark-ignition internal combustion engine. The combustion control apparatus selects an extremely retarded combustion mode while the internal combustion engine is in a predetermined operating state. In the extremely retarded combustion mode, the combustion control apparatus sets ignition timing to be after compression top dead center, and sets fuel injection timing to be before the ignition timing and after compression top dead center. The combustion control apparatus inhibits the extremely retarded combustion mode while an exhaust purifier of the internal combustion engine is in a predetermined cold state.
