Abstract

PURPOSE: To permit the adoption of a comparatively large diameter valve by a method in which a combustion chamber wall for cast-wrapping is separately manufactured of a material having a high wear resistance and cast in when a cylinder head is cast, and then a valve-fitting seat is machined at suction and discharge ports.
CONSTITUTION: A combustion chamber wall 3 is manufactured of a high wear-resistant steel material, e.g., SKD-6, etc., by a precise casting method, e.g., a lost wax method, etc., and then cast into a concavity 2 for molding the combustion chamber by the usual cast-wrapping method when a cylinder head 1 is cast to obtain the cylinder head 1. Then, a valve-fitting seat 7 is directly machined at the lower peripheral edges of suction and discharge ports 4, 5 of the combustion chamber wall 3. Thus, a large diameter valve can be adopted without the needs for allowing for the secureness of keeping a minimum thickness necessary from the standpoint of strength between sheet holes in case where valve sheets are pressed in or fitted in by baking, as in the conventional cases.
