Abstract
An air suction device for a diesel engine having a throttle valve disposed within an air suction passage wherein the throttle valve has an opening through which air may pass even when the throttle valve is in a closed position and wherein a mechanism is positioned adjacent that hole to selectively control the amount of air passing through that hole when the throttle valve is in a closed position.
