Abstract
Exhaust ports and an exhaust gas gathering portion are formed within a cylinder head. A main passage is formed within an engine body. Through the main passage, a coolant is introduced from the inside of a cylinder block into the inside of the cylinder head at portions near exhaust valves, flows in portions near intake valves and portions near intake ports toward a side wall face of the cylinder head in the lateral direction of the engine body, and then flows into the cylinder block. A portion of the coolant, which is introduced into the portions near the exhaust valves, is caused to flow in portions near the exhaust ports toward a side wall face of the cylinder head, and then flows along the side wall face toward a coolant outlet.
