Abstract

Die Erfindung bezieht sich auf einen flüssigkeitsgekühlten Zylinderkopf (1) einer mehrzylindrigen Brennkraftmaschine mit einem Kühlwasserraum (2), in dem in Richtung einer Motorquerachse (7) verlaufende Gaswechselkanäle (5) und mindestens eine Kammer (6) für eine Zündkerze und/oder eine Einspritzdüse angeordnet sind, und mit Schraubenpfeifen (11) zur Verteilung der Schraubenspannkräfte der Zylinderkopfschrauben (8), wobei der Zylinderkopf (1) unter Zwischenschaltung einer Zylinderkopfdichtung mit einem Kurbelgehäuse (9) der Brennkraftmaschine verbindbar ist.
Um einen flüssigkeitsgekühlten Zylinderkopf (1) einer mehrzylindrigen Brennkraftmaschine so auszubilden, daß auch bei beengten Platzverhältnissen eine möglichst hohe und gleichmäßige Flächenpressung der Zylinderkopfdichtung auch in den Bereichen zwischen den Zylinderkopfschrauben (8) zu erzielen ist, wird erfindungsgemäß vorgeschlagen, daß benachbarte Wandabschnitte der Gaswechselkanäle (5) im Bereich der Zylinderkopfschrauben (8) zur Bildung von Rippen verdickt ausgeformt sind, die Teil der Schraubenpfeifen (11) sind.

Figure 00000001
The invention relates to a liquid-cooled cylinder head (1) of a multi-cylinder internal combustion engine with a cooling water chamber (2), in which gas exchange channels (5) extending in the direction of a transverse engine axis (7) and at least one chamber (6) for a spark plug and / or an injection nozzle are arranged, and with screw pipes (11) for distributing the screw clamping forces of the cylinder head screws (8), the cylinder head (1) being connectable to a crankcase (9) of the internal combustion engine with the interposition of a cylinder head gasket.
In order to design a liquid-cooled cylinder head (1) of a multi-cylinder internal combustion engine in such a way that the greatest possible and uniform surface pressure of the cylinder head gasket can also be achieved in the areas between the cylinder head bolts (8), even in confined spaces, it is proposed according to the invention that adjacent wall sections of the gas exchange channels ( 5) are thickened in the area of the cylinder head screws (8) to form ribs which are part of the screw pipes (11).
