Abstract
The invention relates to a cylinder head () with at least one recess () for arranging at least one gas valve () and at least one spark plug (). The spark plug () reaches into a pre-chamber () and is arranged along a spark plug rotational axis (), and the gas valve () is arranged along a gas valve rotational axis (), wherein the gas valve rotational axis () is inclined relative to the spark plug rotational axis (), and the distance (A) between the gas valve rotational axis () and the spark plug rotational axis () decreases as the distance to the pre-chamber () increases in a direction facing away from the combustion chamber (). The aim of the invention is to provide an improved cylinder head () which allows an improved assembly and requires less installation space. According to the invention, this is achieved by the aforementioned cylinder head () in that the recess () for the spark plug () and the gas valve () has a surface () which is formed by a primary molding process, preferably a casting process, and is post-processed particularly preferably without machining.
