ABSTRACT:
An intake apparatus for an internal combustion engine, including a partition extending in a longitudinal direction of an intake port so as to divide an inside region of the intake port into a first passage and a second passage, and a gas motion control valve disposed at a downstream end of an intake manifold and adjacent to an upstream end of the partition. The gas motion control valve includes a rotatable valve element and has a full-closed position where the valve element fully closes the second passage of the intake port and a full-open position where the valve element fully opens the second passage of the intake port. The valve element and the partition cooperate with each other to define an interspace between the valve element and the upstream end of the partition when the gas motion control valve is in the full-closed position.
