Abstract

Official abstract text for this publication.

A cylinder head comprising at least one pre-chamber, at least one spark plug projecting into the pre-chamber, and at least one pre-chamber gas valve opening into the pre-chamber, wherein the spark plug and the pre-chamber gas valve are arranged in a common cavity of the cylinder head, wherein the spark plug and the pre-chamber gas valve are arranged in bores which mutually pass through each other.

First claim

Opening claim text (preview).

1 . A cylinder head comprising at least one pre-chamber, at least one spark plug projecting into the pre-chamber, and at least one pre-chamber gas valve opening into the pre-chamber, wherein the spark plug and the pre-chamber gas valve are arranged in a common cavity of the cylinder head, wherein the pre-chamber gas valve and the spark plug are arranged in bores which mutually pass through each other. 2 . A cylinder head as set forth in claim wherein the spark plug is arranged in a spark plug sleeve, wherein the cavity is provided in the spark plug sleeve. 3 . A cylinder head as set forth in claim 1 , wherein sealing of the pre-chamber gas valve relative to the cylinder head or the spark plug sleeve is effected over the periphery of the pre-chamber gas valve. 4 . A cylinder head as set forth in claim 3 , wherein sealing of the pre-chamber gas valve is by way of at least one O-ring. 5 . A cylinder head as set forth in claim 4 , wherein the at least one O-ring is arranged in an opening formed by projections at the outside wall of the pre-chamber gas valve. 6 . An internal combustion engine having a cylinder head as set forth in claim 1 . 7 . A cylinder head as set forth in claim 2 , wherein sealing of the pre-chamber gas valve relative to the cylinder head or the spark plug sleeve is effected over the periphery of the pre-chamber gas valve. 8 . An internal combustion engine having a cylinder head as set forth in claim 2 . 9 . An internal combustion engine having a cylinder head as set forth in claim 3 . 10 . An internal combustion engine having a cylinder head as set forth in claim 4 . 11 . An internal combustion engine having a cylinder head as set forth in claim 5 .
