Description
Die Erfindung bezieht sich nach dem Oberbegriff des Patentanspruches 1 auf eine flüssigkeitsgekühlte Brennkraftmaschine mit einem Zweikreiskühlsystem, bei dem ein flüssigkeitsgekühltes Zylinder-Kurbelgehäuse und ein gesonderter, flüssigkeitsgekühlter Zylinderkopf über Durchbrechungen in einer zwischengeschalteten Zylinderkopfdichtung temperaturabhängig ventilgesteuert kühlmittelführend verbunden sind.The invention relates according to the preamble of

Der Erfindung liegt die Aufgabe zugrunde, für eine gattungsgemäße Brennkraftmaschine ohne besonderen baulichen Aufwand eine einfachere Kühlmittelsteuerung zwischen Kurbelgehäuse und Zylinderkopf aufzuzeigen.The invention has for its object to show a simpler coolant control between the crankcase and cylinder head for a generic internal combustion engine without special construction effort.
Diese Aufgabe wird durch die Merkmale im kennzeichnenden Teil des Patentanspruchs 1 gelöst.This object is solved by the features in the characterizing part of
In einer Ausgestaltung der Erfindung sind den Durchbrechungen einer üblichen Zylinderkopfdichtung Bimetall-Zungenventile zugeordnet.In one embodiment of the invention, the openings of a conventional cylinder head gasket bimetallic tongues are assigned.
Gemäß einer weiteren Ausgestaltung der Erfindung wird vorgeschlagen, dass eine laminatartig ausgebildete Zylinderkopfdichtung eine Bimetallplatte umfasst, die Durchbrechungen zugeordnete, mittels Freischnitten freigestellte Zungenventile aufweist.According to a further embodiment of the invention, it is proposed that a cylinder-head gasket formed in the manner of a laminate comprises a bimetallic plate which has openings which are assigned by means of cutouts and which have cut-off tongue valves.
Der Vorteil der Erfindung ist, dass ein oder mehrere, der Kühlmittelsteuerung dienende Ventile als Bimetall-Ventile in einer Zylinderkopfdichtung integriert angeordnet sind und damit aufwendige Ventilaufnahmen im Zylinder-Kurbelgehäuse und/oder im Zylinderkopf vorteilhaft entfallen.The advantage of the invention is that one or more, the coolant control valves are arranged as bimetallic valves integrated in a cylinder head gasket and thus costly valve seats in the cylinder crankcase and / or account advantageously in the cylinder head.
Die Erfindung ist anhand eines in der Zeichnung dargestellten Ausführungsbeispiels beschrieben. Es zeigtThe invention is described with reference to an embodiment shown in the drawing. It shows
Eine nicht gezeigte, flüssigkeitsgekühlte Brennkraftmaschine umfasst ein Zweikreiskühlsystem, bei dem ein flüssigkeitsgekühltes, abschnittsweise dargestelltes Zylinder-Kurbelgehäuse
Zur Erzielung einer vorbestimmten, temperaturabhängigen Kühlmittelströmung zwischen Kurbelgehäuse
Vorzugsweise ist eine laminatartig ausgebildete Zylinderkopfdichtung
Im Rahmen der Erfindung ist es auch denkbar, den Durchbrechungen
