Summary:In combustion control apparatus and method for a spark-ignited internal combustion engine, a counter is set to correspond to a drive time duration from a time at which a combustion drive state of the engine is started to be in a stratified combustion drive state to a time immediately before a smolder of a spark plug occurs in a state of which a spark is emitted between an outer electrode of the spark plug and a carbon deposited on an insulator porcelain thereof, a determination of whether it reaches to a time at which the stratified combustion drive state is inhibited is executed on the basis of a value of the counter, and the combustion drive state is forcibly switched from the stratified combustion drive state to a homogeneous combustion drive state when such a determination is carried out that it reaches to the time at which the stratified combustion drive state is inhibited.
