Abstract

Im Zylinderkopf einer Mehrzylinder-Brennkraftmaschine sind am Umfang jedes einem Zylinder zugeordneten Brennraumes zwischen benachbarten Schraubenpfeifen für die Zylinderkopfschrauben an dieser angeformte, in Quer- und Längsrichtung des Zylinderkopfes verlaufende Wände vorgesehen, die sich bis zum Zylinderkopfboden erstrecken. Um die Schraubenkräfte überwiegend auf die Längs- und Querwände übertragen zu können und eine Anpressung des Zylinderkopfes insbesondere über den Umfang jedes Brennraumes zu erreichen, endet die Tragfunktion der Schraubenpfeifen jeweils in einem Abstand vom Zylinderkopfboden. In dem sich hierdurch zwischen Schraubenpfeifenende und Zylinderboden an sich einstellenden Freiraum sind nicht tragende Trennwandbereiche vorgesehen, die lediglich die Funktion haben, die durch die Schraubenpfeifen geführten Zylinderkopfschrauben von angrenzenden Kühlwasserräumen zu trennen. Durch eine solche Abtrennung der Zylinderkopfschrauben von Kühlwasser können diese Schrauben nicht materialschädigend von dem Kühlwasser angegriffen werden. Andererseits bleibt die kraftübertragende Optimierung des Zylinderkopfes mit gekürzten Schraubenpfeifen vollständig erhalten.
