Zusammenfassung:	Methods and systems are provided for a charge motion control valve mounted within a flow passage in an intake manifold coupled to an engine. In one example design, a control valve comprises a valve plate with a pivot axis mounted in a body coupled to a manifold runner, the plate having a rear portion overhanging the pivot; and a first sealing surface in the manifold runner to receive a surface of the rear portion of the valve plate when fully opened; and a second sealing surface in the body to receive an opposite surface of the rear portion of the valve plate when fully closed. In this way, the valve plate may be adjusted to block a portion of a flow passage within the body to minimize air leakages at a periphery of the passage while redirecting air flow to create swirl motion downstream of the valve plate.
