Abstract: An assembly of a cylinder head and a fuel injector with an injector tip for an internal combustion engine with at least one combustion chamber, wherein the fuel injector at the end facing a combustion chamber of the internal combustion engine is at least partially surrounded by a heat shield, wherein in the region of the heat shield a heat dissipation device is provided, through which heat can be dissipated from the combustion chamber of the internal combustion engine, wherein the heat shield surrounds the fuel injector as far as the injector tip, wherein the heat shield is designed as a tapering collar towards the injector tip and is integrated into an injector sleeve or into the cylinder head.

Abstract: 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.

Abstract: A pre-chamber gas valve including a valve body, at least one valve spring and at least one valve needle, wherein the valve body has a lower space which is acted upon with gas in the operating condition and an upper space in which the valve spring is arranged, wherein the upper space is closed by way of a pressed plug.

Abstract: A cylinder head comprising a cavity for receiving a pre-chamber gas valve, wherein an opening extending substantially or completely around the pre-chamber gas valve forms an annular passage with a wall of the cavity, that surrounds the pre-chamber gas valve, wherein the annular passage is connected to at least one gas feed passage for supplying the pre-chamber gas valve with combustion gas, wherein the annular passage with at least one inclined gas passage is connected with the lower cavity of the pre-chamber gas valve.
