Abstract
A plural port intake manifold with outlets aligned along a common cylinder head plane and each intake port containing, a valve unit including a valve plate that is rotatable by a shaft along an axis of rotation recessed within an inner wall as well as a welded connection encircling each intake port upstream of the axis. The system may allow the use of a plate CMCV that can fully retract into the intake runner when not in use.
