ことを特徴とする内燃機関の吸気ポート。An introduction path that guides intake air toward the intake valve, and
In an intake port of an internal combustion engine, the intake port of an internal combustion engine is composed of a curved passage formed continuously with the intake passage and guiding intake air in the direction of the valve stem of the intake valve, and an intake port through which the intake air flowing down the curved passage flows into the combustion chamber. A step portion is provided protruding near the curved road side of the introduction path to give directionality to the intake air toward the curved path, and this step portion is formed in a range that does not reach the inlet side portion of the cross section of the introduction path. An intake port for an internal combustion engine, characterized in that the intake port has a wall surface extending in a direction parallel to a valve stem direction.
