Abstract
The disclosure provides a multi-cylinder internal combustion engine having a cylinder head that includes an exhaust port capable of cooling exhaust gas more effectively. The cylinder head includes: a first ceiling surface that closes a first cylinder having a cylinder axis separated from an exhaust opening by a first distance; a second ceiling surface that closes a second cylinder having a cylinder axis separated from the exhaust opening by a second distance shorter than the first distance; and an exhaust port that extends toward the exhaust opening from two port openings which are open to a combustion chamber for each individual cylinder. The exhaust port individually extends from each of the port openings and merges with each cylinder outside a joining surface of the cylinder head for a cylinder block in a plan view.
