置。[Claims for Utility Model Registration] A dome portion that communicates with the combustion chamber is formed inside the cylinder head, and an intake port portion that communicates with the combustion chamber in a helical manner is formed in the upper part of the dome portion. In an intake system for an internal combustion engine, the opening area between the intake manifold and the intake port section is adjusted in an intake system for an internal combustion engine, in which a raised part is formed on one side wall of the communication part so that a swirl flow is generated on the side opposite to the raised part. An intake system for an internal combustion engine, comprising: an appropriate number of shielding plates movable in a direction perpendicular to an intake passage; and a driving means for moving the shielding plates in a direction perpendicular to the intake passage.
