Abstract: PURPOSE: A water jacket for a cylinder head is provided to improve the whole cooling efficiency through lowering the temperature of a combustion chamber of a cylinder head because a flow of cooling water is guided to the combustion chamber through a cut part. CONSTITUTION: A water jacket for a cylinder head(200) is placed inside the cylinder head. A protruded portion having one or more exhaust outlets is placed on one side of the cylinder head. Upper and lower water jackets are formed inside the protruded portion.

Abstract: PURPOSE: A structure of intake port of an engine is provided to minimize fluctuation of flow rate of fuel-air mixture. CONSTITUTION: An intake port is formed by sand core method during process manufacturing a metal mold for forming a cylinder head. 2 deg. of a snap slope is formed in vertical direction to allow easy separation of the mold. Sectional area of the intake port is gradually reduced from a flange part(41) to a middle part(42). A fuel injecting part(43) is widely formed on an upper side of the flange part. Height of the fuel injection part is gradually reduced to approximately 30mm so that a central part thereof is formed flat on the middle part. A branched part(44) is formed on a downstream of the middle part of the intake port so that two valves are mounted on a combustion chamber. Section of the branched part is changed from a square with convex sides to an approximate circle with rounded corners. Valve guide parts(45) are formed on an upper side of the branched parts of the intake port. Sectional area is gradually increased from the valve guide part to a valve seat part(46).
