Abstract

Die Erfindung betrifft einen Zylinderkopf für eine wassergekühlte Mehrzylinder-Brennkraftmaschine mit Bohrungen (1) zur Aufnahme von Schrauben zur Verbindung mit einem Kurbelgehäuse und mit einem Boden (4) und einer Decke (5), die einen Kühlwasserkanal (6) begrenzen, der von Gaswechselkanälen und pro Zylinder von einem eine Zündkerze oder eine Einspritzdüse aufnehmenden Schacht (3) durchsetzt ist, wobei der Boden (4) im Bereich der die Bohrungen enthaltenden Querebenen mit Zuführöffnungen für Kühlwasser versehen ist, das den Zylinderkopf ein Längsrichtung durchströmt. Zur Optimierung der thermisch hoch belasteten Bereiche des Zylinderkopfes ist vorgesehen, daß in den die Bohrungen (1) enthaltenden Querebenen Zwischendecks (10) angeordnet sind, die den von den Zuführöffnungen (7) nach oben gerichteten Kühlwasserstrom seitwärts gegen das benachbarte Brennraumdach (9) führen.

The invention relates to a cylinder head for a water-cooled multi-cylinder internal combustion engine with bores (1) for receiving screws for connection to a crankcase and with a bottom (4) and a ceiling (5) defining a cooling water channel (6) of the gas exchange channels and per cylinder is penetrated by a shaft (3) receiving a spark plug or an injection nozzle, wherein the bottom (4) is provided with supply openings for cooling water in the region of the transverse planes containing the bores, which flows through the cylinder head in a longitudinal direction. To optimize the thermally highly loaded areas of the cylinder head is provided that in the bores (1) containing transverse planes intermediate decks (10) are arranged, which lead from the supply openings (7) upward cooling water flow sideways against the adjacent combustion chamber roof (9) ,
