Abstract
Description
Die Erfindung betrifft eine flüssigkeitsgekühlte Brennkraftmaschine mit den Merkmalen aus dem Oberbegriff des Patentanspruchs 1.The The invention relates to a liquid-cooled internal combustion engine with the features of the preamble of claim 1.
Sie
geht von dem US-Patent
Trotz der sehr ausgewogenen Kühlung der Brennkraftmaschine mit dem Kühlmittelmantel ist es möglich, dass bei extrem hoher Belastung der Brennkraftmaschine die Stegbereiche und die Zwickelbereiche zwischen den Zylindern am Übergang zu den Stegbereichen übermäßig erhitzt werden.In spite of the very balanced cooling of the internal combustion engine with the coolant jacket, it is possible that at extremely high load on the engine, the land areas and the gusset areas between the cylinders at the transition excessively heated to the land areas become.
Aufgabe der vorliegenden Erfindung ist es, die Kühlung der Brennkraftmaschine, insbesondere in den Steg- und Zwickelbereichen des Kurbelgehäuses weiter zu verbessern.task the present invention is the cooling of the internal combustion engine, especially in the web and gusset areas of the crankcase continue to improve.
Diese Aufgabe wird durch die Merkmale im kennzeichnenden Teil des Patentanspruchs 1 gelöst. Durch die erfindungsgemäße Ausgestaltung erfolgt die Kühlmittelzuführung ins Kurbelgehäuse über den Kühlmittelzuführkanal, der sich weitgehend entlang der Zylinder in der Brennkraftmaschinenlängsachse erstreckt und wobei von dem Kühlmittelzuführkanal abzweigende Zuführkanäle in jedem Steg- und Zwickelbereich eine weitgehend vertikal nach oben, weil von geodätisch unten kommend, gerichtete Strömung in dem Kühlmittelmantel in der ersten Längsseite erzeugen. Das Kühlmittel tritt danach vom Kurbelgehäuse in den Zylinderkopf ein und durchströmt diesen weitgehend in Brennkraftmaschinenquerrichtung. Auf der anderen Seite wird über einen Kühlmittelmantel in der zweiten Längsseite, der sich ebenfalls weitgehend entlang der Zylinder erstreckt, das Kühlmittel bevorzugt vertikal nach unten aus dem Kurbelgehäuse abgeführt, wodurch sich wieder eine günstige Kühlwirkung der Steg- und Zwickelbereiche ergibt. Die Kühlmittelabfuhr aus dem Kühlmittelmantel in der zweiten Längsseite kann also analog der Kühlmittelzufuhr erfolgen, in diesem Fall erfolgt die Kühlmittelabfuhr jedoch nach geodätisch unten, ebenfalls bevorzugt in dem Zwickelbereich.These The object is achieved by the features in the characterizing part of the claim 1 solved. By the invention Design takes place the coolant supply into the crankcase via the coolant supply channel, which extends largely along the cylinder in the engine longitudinal axis and wherein branching from the coolant supply passage Feed channels in each web and gusset area a largely vertical upward because of geodesic coming down, directed flow in the coolant jacket generate in the first longitudinal side. The coolant then enters from the crankcase into the cylinder head and flows through this largely in the engine transverse direction. On the other hand is over a coolant jacket in the second longitudinal side, which is also largely extends along the cylinder, the coolant is preferred discharged vertically downwards out of the crankcase, which again gives a favorable cooling effect the web and gusset areas results. The coolant removal from the coolant jacket in the second longitudinal side can therefore be carried out analogously to the coolant supply, in this Case, however, the coolant discharge takes place after geodesic below, also preferably in the gusset area.
Die Ausgestaltungen gemäß der Patentansprüche 2 und 3 verbessern die Kühlung der Steg- und Zwickelbereiche nochmals.The Embodiments according to the claims 2 and 3 improve the cooling of the web and gusset areas again.
Die Ausgestaltungen gemäß Patentanspruch 4 sind zwei Ausführungsbeispiele, wobei die auslassseitige Anordnung die bevorzugte Anordnung ist, mit der in der Praxis gleichmäßigeren Kühlung der Brennkraftmaschine.The Embodiments according to claim 4 are two Embodiments, wherein the outlet side arrangement the preferred arrangement is, with the more uniform in practice Cooling of the internal combustion engine.
Im Folgenden ist die Erfindung anhand von drei bevorzugten Ausführungsbeispielen in sechs Figuren näher erläutert.in the The invention is based on three preferred embodiments explained in more detail in six figures.
Im

Ferner
sind der Kühlmittelmantel in der ersten Längsseite
In

In
einer weiteren besonders bevorzugten Ausführungsform können

Um
eine bestmögliche Homogenisierung der Temperaturverteilung

Mit
anderen Worten ausgedrückt:
Durch die erfindungsgemäße
Kühlmittelzuführung in den Kühlmittelmantel
in der ersten Längsseite
By the coolant supply according to the invention in the coolant jacket in the first longitudinal side
Durch den Druckverlust im Zylinderkopf ergibt sich ein großer Druckunterschied im Kurbelgehäuse zwischen Ein- und Auslassseite, was eine hohe Strömungsgeschwindigkeit in einer Stegkühlungsbohrung und damit eine gute Kühlwirkung der Stege garantiert.By the pressure loss in the cylinder head results in a large Pressure difference in the crankcase between inlet and outlet side, what a high flow velocity in a land cooling hole and thus guarantees a good cooling effect of the bars.
Somit ist gegenüber dem bekannten Stand der Technik die Kühlung, insbesondere im Stegbereich eines Kurbelgehäuses, über die gesamte Zylinderhöhe verbessert, wodurch höhere Leistungsdichten für die Brennkraftma schine möglich sind.Consequently is compared to the prior art, the cooling, especially in the web area of a crankcase, via the overall cylinder height is improved, resulting in higher Power densities for the internal combustion engine possible are.
