Claims

[Scope of utility model registration request]

The intake port consists of a straight port that extends almost horizontally from the intake port inlet and then gradually curves downward toward the intake valve, and protrudes from one side of the intake port toward the other side and extends from around the intake valve stem. A partition wall extending toward the upstream side of the intake port is formed within the intake port, and the protruding tip edge of the partition wall is spaced apart from the other side of the intake port, and the partition wall divides the interior of the intake port into an upper passage and a lower passage. An intake system for an internal combustion engine in which an intake control valve that is divided and fully opened during high engine load operation is provided in the lower passage.
