Abstract

A cylinder head is formed with a pre-chamber surrounded by a thin pre-chamber wall sticking out from the inside wall surface of the cylinder head to the inside of the main combustion chamber. Inside of the pre-chamber, the electrode of a spark plug is arranged. When the spark plug is used to burn the air-fuel mixture in the pre-chamber, jet flames are ejected from the communication holes to the main combustion chamber. The thin pre-chamber wall is formed from a metal material while the overall outer circumferential surface around the communication holes passing through the thin pre-chamber wall is formed by a material with a lower heat conductivity than the thin pre-chamber wall.
