摘要: An internal combustion engine includes a cylinder head including an intake port, an exhaust port, a water jacket, an intake valve, an exhaust valve, an intake valve seat, and an exhaust valve seat. The water jacket is positioned between the intake port and the exhaust port. The intake valve includes an intake valve head, and the exhaust valve includes an exhaust valve head. The intake valve contacts an intake valve seat surface of the intake valve seat. The exhaust valve head contacts an exhaust valve seat surface of the exhaust valve seat. The shortest distance between the water jacket and the intake valve seat surface is shorter than the shortest distance between the water jacket and the exhaust valve seat surface.

摘要: An intake port of an internal combustion engine is connected to a combustion chamber and includes a connecting portion having a passage cross-sectional area that increases as the connecting portion approaches the combustion chamber, and an upstream portion connected to an upstream end of the connecting portion. The connecting portion is provided at its downstream end with a valve seat with which an umbrella part of an intake valve is brought into contact. At least one recess extending in an extending direction of the intake port and included in the connecting portion and the upstream portion is provided at least at one of two portions, the two portions located on both sides in an extending direction of an output shaft, of a peripheral surface of the intake port.
