Abstract
An intake passage of an internal combustion engine is divided into two intake passages downstream of a throttle valve. A tumble generating valve is disposed in one of these two intake passages. When the engine is stopped, the tumble generating valve is fully closed once and then opens by a specified opening angle. While the engine is inoperative, the tumble generating valve is held at that angle until the engine is started again.
