ル型吸気ポート。 In a helical intake port configured with a spiral part and an inlet passage part connected tangentially to the spiral part and extending almost straight, the cross-sectional shape of the inlet passage part is formed into a polygon. One corner smoothly transitions from the entrance of the inlet passage toward the terminal end of the inlet passage, from the upper end of the side wall of the inlet passage on the side of the spiral axis to the upper end of the side wall of the inlet passage on the opposite side of the spiral axis. A helical intake port for an internal combustion engine in which the cross-sectional shape of the inlet passage is changed.
