摘要: A first object of the invention is to reduce an exhaust gas in a lean burn area which is expanded by a supercharging, in a direct gasoline injection type internal combustion engine provided with a turbocharger. A second object of the invention is to prevent a knocking and a misfire at a time of self ignition combustion. The invention is used for the direct gasoline injection type internal combustion engine provided with the turbocharger. In order to achieve the first object, a combustion mode is switched from a stratified combustion mode to a self ignition combustion mode at a time when a suction pressure of the engine is equal to or more than an atmospheric pressure. Further, in order to achieve the second object, an ignition timing is set to a range between a top dead center and 10 degrees after the top dead center (0 to 10 (ATDC)) at a time of operating an engine in accordance with a self ignition combustion mode.
