Abstract
A deflector plate is pivotally mounted in an intake passage of an engine so as to reduce the cross-sectional area of the intake passage, and an actuator is provided for operating the deflector plate. A control unit is provided for operating the actuator so that the deflector plate operates to reduce the cross-sectional area of the intake passage to increase the swirl ratio of the intake air as the combustion condition deteriorates.
