PROBLEM TO BE SOLVED: To improve engine intake air quantity control precision. SOLUTION: Acceleration openingθa, engine rotation speed Ne, water temperature Tw, etc., are inputted (S1), stratified charge combustion or homogeneous combustion is selected based on these (S2), if combustion changing demand is provided or not is determined (S3), if homogeneous combustion is currently performed or not is determined in the case where the changing demand is not provided (S4), a target value of swirl control valve opening tSCV in accordance with homogeneous combustion is selected in the case of homogeneous combustion being performed (S5), and a target value of the swirl control valve opening tSCV corresponding to the stratified charge combustion is selected in the case of stratified charge combustion being performed (S6).
