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).
