路を備えたエンジン部品。[Claims for Utility Model Registration] (1) Consisting of a casting part body and a manifold ceramic liner that is cast into the part body to form a manifold exhaust passage, the ceramic liner has a hollow cylindrical shape. In an engine component equipped with a manifold exhaust passage having a liner body and a plurality of cylinders branching from the liner body, the inside and outside of the ceramic liner are communicated with the branch area of the ceramic liner where both adjacent cylinders branch. The part body is characterized in that a through part is provided, and a guide part that protrudes from the through part into the ceramic liner and guides exhaust gas flowing through both adjacent cylindrical bodies to the liner body is integrally formed in the part body. , engine parts with manifold exhaust passages. (2) The engine component provided with the manifold exhaust passage according to item (1), wherein the opening on the inner surface of the ceramic liner of the penetrating portion is set larger than the opening on the outer surface of the ceramic liner. (3) An engine component equipped with a manifold exhaust passage according to item (1) or item (2), wherein a void existing in the inner wall of the penetrating portion is filled with glass. (4) The penetrating portions are elongated holes that are formed so as to extend in series from the base ends of the two adjacent cylindrical bodies to the opposing portions of the peripheral wall of the liner main body. or an engine part equipped with a manifold exhaust passage as described in paragraph (3). (5) The engine component provided with the manifold exhaust passage according to item (4), wherein the inner surfaces of both longitudinal ends of the elongated hole are formed into arcuate surfaces. (6) The engine component provided with the manifold exhaust passage according to item (4), wherein the inner surfaces of both longitudinal ends of the elongated hole are formed into half-circular arcuate surfaces.
