Abstract
An internal combustion engine cylinder head has a water jacket, a plurality of female threaded portions for attaching an exhaust component, and a plurality of bulging portions protruding into the water jacket. The water jacket has inlet portions for receiving cooling water and outlet portions for discharging the cooling water. The inlet portions are disposed in a central position of the water jacket in a cylinder row direction. The outlet portions are disposed on a lateral side of the cylinder head to which the exhaust component is attached. A spacing between the outlet portions is wider than a spacing between the inlet portions. The female threaded portions protrude into the water jacket so that the cooling water crosses an area around the female threaded portions in the cylinder row direction. The bulging portions extend from ends of the female threaded portions towards where the inlet portions are located.
