PROBLEM TO BE SOLVED: To improve the performance in the converting time of a stratified combustion and a homogeneous combustion in a high response torque controlling condition. SOLUTION: When the converting request from a stratified combustion to a homogeneous combustion is generated in a high response torque controlling condition, the conversion to the homogeneous combustion is permitted (S1→S2→S6), and it is converted to a high response torque control by an ignition timing correcting amount (S7→S8). When the converting request from a homogeneous combustion to a stratified combustion is generated, the conversion of combustion is prohibited until the torque correcting amount of the high response torque control is made less than a specific value, the high response torque control by the ingnition timing correcting amount is continued (S9→S10→S7→S8), and the conversion to the stratified combustion is permitted after the torque correcting amount is made less than the specific value (S10→S11), so as to convert to a high response torque control by an equivalence ratio correcting rate (S4→S5).
