Abstract

The engine has coolant going into the exhaust-side cooling jackets (6, 6') and via cross-flow cylinder heads to the induction-side cooling jackets (7, 7'), then via breaks in the cylinder bank boundaries to an outflow line (15) in the vee cavity (8). This line incorporates the inflow line (9), from which coolant goes via vertical channels to the exhaust-side cooling jackets.

Description

Die deutsche Patentschrift DE 40 01 140 C1 zeigt und beschreibt eine Kühlmittelführung in einem abschnittsweise im Querschnitt dargestellten Zylinder-Kurbelgehäuse eines flüssigkeitsgekühlten V-Motors. Im V-Raum dieses V-Motors sind in Maschinenlängsrichtung eingeformte und durch einen gesonderten Deckel verschließbare Kühlmittelkanäle für einen Kühlmittel-Zulauf und einen Kühlmittel-Ablauf bezüglich der in den Zylinderbänken vorgesehenen Kühlmänteln angeordnet. Somit ist einer Zylinderbank der Kühlmittel-Zulaufkanal und der anderen Zylinderbank der Kühlmittel-Ablaufkanal benachbart zugeordnet, wobei beide Kühlmittelkanäle im wesentlichen durch eine massive, im Querschnitt dreieckförmige Rippe getrennt sind. Jeder der Kühlmittelkanäle steht mit dem benachbarten Kühlmantel in der ihn begrenzenden Zylinderbank über Durchbrechungen in den Zylinderbankbegrenzungen in direkter Verbindung, wobei jeder Kühlmittelkanal mit dem Kühlmantel der anderen, beabstandeten Zylinderbank über in der Rippe angeordnete Winkelkanäle in kühlmittelführender Verbindung steht.The German patent DE 40 01 140 C1 shows and describes a coolant guide in a cylinder crankcase shown in sections in cross section of a liquid-cooled V-engine. In the V space of this V engine are in Machine longitudinal direction molded in and lockable by a separate cover Coolant channels for a coolant inlet and a coolant outlet arranged with respect to the cooling jackets provided in the cylinder banks. Consequently one of the cylinder banks is the coolant inlet channel and the other cylinder bank is the Coolant drain channel assigned adjacent, both coolant channels in the essentially separated by a solid rib, triangular in cross section are. Each of the coolant channels is in the same with the adjacent cooling jacket limiting cylinder bank via openings in the cylinder bank limits in direct connection, each coolant channel with the cooling jacket of the another, spaced-apart cylinder bank via angular channels arranged in the rib is in a coolant-carrying connection.

Bei dieser bekannten Kühlmittelführung in einem V-Motor tritt das zulaufende Kühlmittel innenseitig des V-Raumes in die Kühlmäntel der beiden Zylinderbänke ein und fließt weiter abgasseitig den Zylinderköpfen zu, aus denen es über gesonderte Kanäle in den Zylinderbänken dem Kühlmittel-Ablaufkanal zugeführt ist. Neben einer ungünstigen Wärmeverteilung im Zylinder-Kurbelgehäuse einerseits und einem erheblichen Aufwand an gesonderte Kanälen andererseits in den Zylinderbänken sowie in der dreieckförmigen Rippe der getrennt nebeneinander angeordneten Kühlmittelkanäle sind als wesentliche Nachteile zu nennen.In this known coolant system in a V engine, the incoming coolant occurs inside the V-space into the cooling jackets of the two cylinder banks and continues to flow on the exhaust side to the cylinder heads, from which it is separated Channels in the cylinder banks of the coolant drain channel is supplied. Next an unfavorable heat distribution in the cylinder crankcase on the one hand and a considerable amount of separate channels on the other hand in the Cylinder banks as well as in the triangular rib which are separated side by side arranged coolant channels are to be mentioned as significant disadvantages.

Der Erfindung liegt die Aufgabe zugrunde, für eine gattungsgemäße, insbesondere als V-Motor gestaltete Brennkraftmaschine eine verbesserte Kühlmittelführung aufzuzeigen bei wesentlich einfacherem Aufbau mit besserer Wärmeverteilung.The invention is based, for a generic, in particular the task engine designed as a V-engine to show improved coolant management with a much simpler structure with better heat distribution.
