る吸気ポート構造。[Scope of Claim for Utility Model Registration] An injector is provided in which the fuel injection direction is on the port wall, and the central axis of the intake port is substantially defined between the valve head and the valve seat when the intake valve is opened. In an intake port structure for an internal combustion engine in which an intake port is formed so as to be oriented toward a predetermined area in a space where the intake port is formed, a wall surface portion of the port that the injected fuel from the injector collides with is curved in a concave shape along the longitudinal direction of the port, An intake port structure characterized in that fuel reflected from the wall portion is substantially directed toward the predetermined region.
