Abstract

An engine assembly may include a cylinder head, an intake manifold assembly, first and second vanes, and an actuation mechanism. The first and second vanes may be rotatably coupled to the intake manifold assembly. The first vane may be located within an outlet of a first intake passage and the second vane may be located within an outlet of a second intake passage. The first and second vanes may be displaceable from an open position to a closed position. The first vane may extend along a wall defining the first intake passage when in the open position and the second vane may extend along a wall defining the second intake passage when in the open position. The actuation mechanism may be coupled to the first and second vanes to rotate the first and second vanes between the open and closed positions.
