Abstract

PURPOSE: To product port shape to meet required characteristic efficiently, a previously formed metal plate in dual port shape is fixed to the suction port core in a body when casting a cylinder head, a dual port is formed by casting.
CONSTITUTION: A separating plate 12 is arranged to divide an inside of the suction port 1 to a high port 10 and a lower port 11 nearly along a horizontal surface. The separating plate 12 is formed by plate work and press work, a notch 13 to avoid interference to the valve stem 3a of suction valve 3 is provided, permitting inhaling mixture in the lower port 11 to produce circumferential swirl in the cylinder, a bent guide 14 to point to a tangential direction is provided to increase suction resistance of inhaling mixture in the high port 10. And then the separating plate 12 is cast together with the suction port core when casting a cylinder head, pawls 16a are provided to increase adhesive property to the core for casting.
