PROBLEM TO BE SOLVED: To retain an ignition condition when performing stratified combustion operation at a condition immediately before smoking. SOLUTION: In a combustion controller for a spark ignition type engine switching between stratified combustion operation and homogeneous combustion operation, an engine controller 11 is provided with a counter which specifies an ignition condition in which spark is generated between an external electrode of an ignition plug 5 and adhered carbon in an insulator part as a smoking condition to correspond to operation time up to a condition immediately before smoking when performing stratified combustion operation, an inhibit timing judging means for judging whether it is timing at which stratified combustion operation is inhibitted or not based on a value of the counter, and a switching means for switching to homogeneous combustion operation forcedly when it is judged that it is the timing at which the stratified combustion operation is inhibitted by the inhibit timing judging means.
