ABSTRACT:
The present invention aims at preventing deterioration of driveability due to lean combustion, in a direct injection spark ignition type internal combustion engine. To this end, there is calculated a target engine-torque tTe which is to be generated by the engine, based on an engine driving condition, while detecting an actual engine-torque Te which is being actually generated by the engine. There is further calculated a deviation state quantity .DELTA.TQ=Te-tTe, which represents a deviation state between the target engine-torque and the actual engine-torque. Then, the lean combustion is inhibited when the deviation state quantity .DELTA.TQ is equal to or larger than a predetermined value. Namely, homogeneous lean combustion and stratified lean combustion are inhibited, and the combustion mode is switched to homogeneous stoichiometric combustion.
