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

In control apparatus and method for an inner cylinder spark ignited internal combustion engine having a fuel injection valve configured to directly inject fuel into an inside of an engine cylinder and a spark plug, a super retard combustion is executed to set an ignition timing after a compression stroke top dead center and to inject fuel before the ignition timing and after the compression stroke top dead center during a predetermined engine driving condition and at least part of fuel is injected before the compression stroke top dead center to decrease a fuel injection quantity after the compression stroke top dead center during an interval which is immediately after an engine start and in which a pressure of fuel is relatively low.

Control apparatus and method for inner cylinder direct injection spark ignited internal combustion engine

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.
