Abstract

Für eine flüssigkeitsgekühlte, mehrzylindrige Brennkraftmaschine mit einem am Zylinder-Kurbelgehäuse (2) lösbar angeordneten, quer durchströmten Zylinderkopf (3) wird zur Erzielung einer verbesserten Kühlmittelführung unter Einbindung zumindest eines Teilbereiches einer unterteilten Kühlmittelkammer (5) des Zylinder-Kurbelgehäuses (2) bei wirksamer Entlüftung in einfacher Ausgestaltung vorgeschlagen, daß das Zylinder-Kurbelgehäuse (2) eine in Teilbereiche unterteilte Kühlmittelkammer (5) umfaßt und daß eine im Zylinder-Kurbelgehäuse (2) angeordnete Einrichtung der Weiterleitung des aus dem Zylinderkopf (3) abfließenden Kühlmittels zu einem im Zylinderkopf (3) integrierten Steigkanal (11) dient, wobei eine im Zylinderkopf (3) quer durchströmte Abschnitte (8 bis 8''') in Hochpunkten verbindende Entlüftungsleitung (12) vorgesehen ist, die in den mit einem äußeren Leitungsanschluß (13) verbindbaren Steigkanal (11) in einem Bereich eines geodätischen Höchstpunktes (14) mündet.

Figure 00000001
For a liquid-cooled, multi-cylinder internal combustion engine with a cylinder head (3) which is detachably arranged on the cylinder crankcase (2) and which is flowed through transversely, in order to achieve improved coolant guidance, at least a partial area of a divided coolant chamber (5) of the cylinder crankcase (2) is more effective Ventilation in a simple embodiment proposed that the cylinder crankcase (2) comprises a coolant chamber (5) divided into sections and that a device arranged in the cylinder crankcase (2) for forwarding the coolant flowing out of the cylinder head (3) to one in the cylinder head (3) integrated riser duct (11), wherein a vent line (12) connecting transversely flowed through sections (8 to 8 ''') in the cylinder head (3) is provided, which is connected to the riser duct which can be connected to an outer line connection (13) (11) in a range of a geodetic peak (14) opens.
