ABSTRACT:
An apparatus and method for controlling charge motion in the air intake manifold includes a barrel-style valve rotatably mounted in the lower air intake manifold between the linearly arranged set of air inlets and the first and second sets of laterally offset air outlets which branch to the first and second cylinder banks, respectively. The barrel valve includes a plurality of openings and is rotatable between a fully open position wherein the plurality of openings are in alignment with the respective air inlets and outlets in the lower manifold allowing substantially unimpeded airflow therethrough, and fully closed position wherein the plurality of openings are substantially fully out of alignment with the respective air inlets and outlets substantially preventing air flow therethrough while allowing air flow through an air bypass formed adjacent to each air inlet and outlet pair.
