関の吸気装置。 Each cylinder has a high-swirl intake port with a shape that has a high ability to generate swirl within the combustion chamber,
The high swirl intake port is formed by extending in the axial direction of the intake passage upstream from the branching point with the low swirl intake port, and ,
The passage wall near the branch point is located in the tangential direction along the passage wall near the branch point of the intake passage upstream of the branch point, or on the side away from the axis from the tangent line, and low swirl type intake air is provided. An intake system for an internal combustion engine, characterized in that the port is arranged so that its axial direction branches at a predetermined angle with respect to the intake passage upstream of the branch point.
