Eine flüssigkeitsgekühlte Brennkraftmaschine 1 der Hubkolbenbauart, die für den Einbau in ein Kraftfahrzeug geeignet ist, weist gegenüberliegende Zylinderreihen 2,3 - Boxerbauweise - mit Zylindergehäusen 4,5 auf. Zwischen den Zylinderreihen 2,3 erstreckt sich ein Kurbelgehäuse 6, in dem in einer Mittellängsebene A-A eine nicht näher gezeigte Kurbelwelle verläuft.A liquid-cooled internal combustion engine 1 of the reciprocating type, which for the Installation in a motor vehicle is suitable, has opposite rows of cylinders 2.3 - Boxer design - with cylinder housings 4.5 on. Between the rows of cylinders 2,3 extends a crankcase 6, in which in a central longitudinal plane A-A does not crankshaft shown in detail runs.

Oberhalb des Kurbelgehäuses 6 erstreckt sich ein Träger 7, der zum einen zur Befestigung von mehreren Nebenaggregaten 8 dient und zum anderen zur Führung von Kühlflüssigkeit ausgebildet ist. Der Träger 7 erstreckt mit einem Längsabschnitt 9 zwischen den Zylindergehäusen 4,5 und besitzt Anschlußstutzen 10,11 für Rohrleitungen 12,13. Die Rohrleitungen 12,13 sind mit den Zylindergehäusen 4,5 und den Anschlußstutzen 10,11 verbunden; letztere dienen als Eingänge 14,15 für Kühlwasser aus den Zylindergehäusen 4.5. Das Kühlwasser gelangt über einen mit strichpunktierten Linien dargestellten Kanal 16 im Träger 7 an einen entfernt von den Eingängen 14,15 liegenden Ausgang 17, von dem aus es zu einem nicht gezeigten Kühler der flüssigkeitsgekühlten Brennkraftmaschine 1 geleitet wird. Im Ausführungsbeispiel sind Enden 18,19 der Anschlußstutzen 10,11 in etwa quer zur Längsmittelebene A-A der Brennkraftmaschine ausgerichtet; ebenso die Rohrleitungen 12,13. Beabstandet - in Längsrichtung B-B der Brennkraftmaschine 1 gesehen - zu den Anschlußstutzen 10,11 ist am Träger 7 ein Querabschnitt 20 angeformt, der einen ersten Querarm 21 und einen zweiten Querarm 22 umfaßt, wobei am zweiten Querarm 22 der Ausgang 17 vorgesehen ist. Der Querabschnitt 20 ist mit Aufnahmen 24,25,26 für die Nebenaggregate 8 versehen, die beispielsweise durch eine Lichtmaschine 27, einen Klimakompressor 28 und eine Lenkhilfepumpe 28 dargestellt sind. Die Aufnahmen 23,24,25 sind mit Öffnungen 29 für Befestigungsschrauben versehen, welche Öffnungen 29 sich zumindest teilweise in Lageraugen 30 erstrecken. Die Aufnahmen 24,25,26 weisen an zylindrische Gehäuse 27,28,29 der Nebenaggregate 8 angepaßte Formabschnitte 31,32,33 auf, die die Gehäuse 27,28,29 lediglich bereichsweise umgeben.Above the crankcase 6 extends a carrier 7, which on the one hand Attachment of several ancillary units 8 is used and the other for guidance is formed by coolant.
