ABSTRACT:
An intake apparatus for an internal combustion engine, including a partition dividing an intake port into a first passage and a second passage, and a gas motion control valve including a rotatable valve element disposed upstream of the partition and spaced from an upstream end thereof. The gas motion control valve has a full-closed position where the valve element prevents intake air from flowing into the second passage and a full-open position where the valve element allows the intake air to flow into the second passage. The valve element is inclined so as to guide a flow of the intake air to the first passage when the gas motion control valve is in the full-closed position. The valve element and the partition cooperate with each other to define an interspace therebetween when the gas motion control valve is in the full-closed position.
