Besonders geeignet ist dieses System für bauartgleiche Motorreihen, beispielsweise Sechszylinder-Boxermotor mit einer luftgekühlten (= zwei Ventile pro Zylinder) und einer wassergekühlten (= vier Ventile pro Zylinder) Variante, weil die unterschiedlichen Ausführungen kompatibel sind.The main advantages achieved with the invention are the following: that the internal combustion engine while maintaining a simple cylinder version is equipped with a highly effective liquid cooling system. This system is particularly suitable for identical motor series, For example, a six-cylinder boxer engine with an air-cooled (= two Valves per cylinder) and one water-cooled (= four valves per Cylinder) variant because the different versions are compatible are.

In der Zeichnung ist ein Ausführungsbeispiel der Erfindung dargestellt, das nachstehend näher beschrieben ist. Es zeigtIn the drawing, an embodiment of the invention is shown, the is described in more detail below. It shows

Fig. 1 einen Teilquerschnitt einer Brennkraftmaschine im Bereich eines Zylinders und eines Zylinderkopfs, Fig. 1 is a partial cross-section of an internal combustion engine in the region of a cylinder and a cylinder head,

Fig. 2 einen Schnitt nach der Linie II-II der Fig. 1. Fig. 2 shows a section along the line II-II in FIG. 1.

Die mehrzylindrige Brennkraftmaschine 1 umfaßt in dem dargestellten Bereich einen einzelnen, separaten Zylinder 2 und einen Zylinderkopf 3. Der Zylinder 2 ist auf der einen Seite - bei 4 - in ein Kurbelgehäuse 5 eingesetzt, wogegen er auf der gegenüberliegenden Seite mit dem einteiligen Zylinderkopf 3 verbunden ist. Besagter Zylinderkopf 3 ist mit einem Einlaßkanal 6 und einem Auslaßkanal 7 ausgestattet, die an einen Brennraum 8 angeschlossen sind. Die Gaswechselsteuerung im Brennraum 8 wird mittels hubbeweglicher Ventile 9, 10 bewerkstelligt, die V-förmig im Zylinderkopf 3 angeordnet sind.The multi-cylinder internal combustion engine 1 comprises a single, separate cylinder 2 and a cylinder head 3 in the area shown . The cylinder 2 is inserted on one side - at 4 - into a crankcase 5 , whereas it is connected to the one-piece cylinder head 3 on the opposite side. Said cylinder head 3 is equipped with an inlet duct 6 and an outlet duct 7 , which are connected to a combustion chamber 8 . The gas exchange control in the combustion chamber 8 is accomplished by means of liftable valves 9, 10 , which are arranged in a V-shape in the cylinder head 3 .

Zur Kühlung der Brennkraftmaschine 1 bzw. ihrer Zylinder 2 und des Zylinderkopfs 3 dient flüssiges Medium. Dieses wird von einer seitlich vom Zylinder 2 verlaufenden Zuführungsleitung 11 aus in einen ersten Kanal 12 des Zylinders 2 gefördert. Der Kanal 12 erstreckt sich ringartig entlang der Längsseite und über einen Teilbereich A der Länge des Zylinders 2, der eine rechteckige Grundform aufweist (Fig. 2). Übrigens ist der Kanal 12 in etwa koaxial zur Zylinderbohrung 13 angeordnet. Außerdem ist der Kanal 12 an eine Bohrung 14 im Zylinderkopf 3 angeschlossen, die in einen ersten Längskanal 15 des besagten Zylinderkopfs mündet. Von dort aus werden - in Querrichtung B-B der Brennkraftmaschine 1 gesehen - die Ventile 9, 10 umgebende Kanäle 16, 17 und 18 mit dem Kühlmedium durchspült, das dann in einen zweiten Längskanal 19 im Zylinderkopf 3 gelangt. Der Längskanal 19 ist an einen zweiten, im Zylinder 2 vorgesehenen Kanal 20 angeschlossen, der konstruktiv dem ersten Kanal 12 im wesentlichen entspricht. Schließlich steht der Kanal 20 mit einer seitlich vom Zylinder 20 verlaufenden Sammelleitung 21 in Verbindung.Liquid medium is used to cool the internal combustion engine 1 or its cylinders 2 and the cylinder head 3 . This is conveyed from a supply line 11 running laterally from the cylinder 2 into a first channel 12 of the cylinder 2 . The channel 12 extends like a ring along the long side and over a partial region A of the length of the cylinder 2 , which has a rectangular basic shape ( FIG. 2). Incidentally, the channel 12 is arranged approximately coaxially with the cylinder bore 13 . In addition, the channel 12 is connected to a bore 14 in the cylinder head 3 , which opens into a first longitudinal channel 15 of said cylinder head. From there - seen in the transverse direction BB of the internal combustion engine 1 - the valves 9, 10 surrounding channels 16, 17 and 18 are flushed with the cooling medium, which then reaches a second longitudinal channel 19 in the cylinder head 3 . The longitudinal channel 19 is connected to a second channel 20 which is provided in the cylinder 2 and which corresponds structurally to the first channel 12 . Finally, the channel 20 is connected to a manifold 21 extending laterally from the cylinder 20 .

Die Zuführungsleitung 11 und die Sammelleitung 21 sind getrennt vom Zylinder hergestellt, wobei beide mit Rohrstutzen 22, 23 an die Zylinder 2, 2′ angeschlossen sind. Die Breite der Öffnung 24 der Rohrstutzen 22, 23, die an den Zylinder 2 anschließt, entspricht weitgehend der Breite C der Kanäle 12 und 20.The feed line 11 and the manifold 21 are made separately from the cylinder, both of which are connected to the cylinder 2, 2 ' with pipe sockets 22, 23 ' . The width of the opening 24 of the pipe socket 22, 23 , which adjoins the cylinder 2 , largely corresponds to the width C of the channels 12 and 20 .

Gemäß Fig. 2 ist die Sammelleitung 21 an jedem Zylinder 2, 2′ unter Vermittlung von Schrauben 25 befestigt. Darüber hinaus weist die Sammelleitung 21 einen Klopfsensor 26 auf, der in eine Gewindebohrung 27 der Sammelleitung 21 eingedreht ist.Referring to FIG. 2, the manifold 21 to each cylinder 2, 2 'is fixed through the intermediary of screws 25. In addition, the manifold 21 has a knock sensor 26 which is screwed into a threaded bore 27 of the manifold 21 .
