The water jacket (19) is positioned between the intake port (17) and the exhaust port (18). The intake valve (20) includes an intake valve head (22), and the exhaust valve (30) includes an exhaust valve head (32). The intake valve head (22) is configured to contact an intake valve seat surface (261) of the intake valve seat (26). The exhaust valve head (32) is configured to contact an exhaust valve seat surface (361) of the exhaust valve seat (36). The shortest distance between the water jacket (19) and the intake valve seat surface (261) is shorter than the shortest distance between the water jacket (19) and the exhaust valve seat surface (361).",
