  • Combustion control apparatus for direct-injection spark-ignition internal combustion engine
    Publication number: 20060266020
    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.

  • Combustion control apparatus for direct-injection spark-ignition internal combustion engine
    Publication number: 20060016425
    Abstract: A combustion control apparatus configured to operate a direct-injection spark-ignition internal combustion engine in a top dead center injection operating mode. In the top dead center injection operating mode, a fuel injection start timing is set to be before compression top dead center, a fuel injection end timing is set to be after compression top dead center, and an ignition timing is set to be after compression top dead center. The combustion control apparatus is configured to promote incylinder fuel spray penetration.
