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.

摘要： A control method of an internal combustion engine with which braking force while reducing the speed of the motor vehicle can be established by generating pumping loss effectively by using a variable valve mechanism enabling to control arbitrarily the open-close timing and the lift amount of air intake and exhaust valves of the engine. When the break step-on force detection means detects a step-on force on a brake and an operation of the anti-lock brake system is selected, at least one of the intake valve or the exhaust valve is made close, another one not closed of the intake valve or the exhaust valve is made open once in a single revolution of the engine while a piston moves from a top dead center to a bottom dead center, and a lift of the valve is controlled to be a designated value.
