In order to improve cooling, at least one coolant inlet which can be connected with a pressure source opens into the cooling jacket of the cylinder housing and the cooling jacket is flow-connected directly with the upper partial cooling chamber via at least one riser manifold, so that coolant flows in engine operation from the pressure source to the cooling jacket of the cylinder housing and from there to the upper partial cooling chamber of the cylinder head and further via the transfer opening into the bottom partial cooling chamber and from there to the pressure sink.

Description

Die Erfindung betrifft eine flüssigkeitsgekühlte Brennkraftmaschine mit einem Zylindergehäuse für zumindest einen Zylinder und zumindest einem Zylinderkopf, wobei der zumindest eine Zylinder im Zylindergehäuse von einem Kühlmantel umgeben ist und wobei im mit dem Zylindergehäuse verbundenen Zylinderkopf ein an ein Feuerdeck grenzender unterer Teilkühlraum und ein mit diesem über zumindest eine Überströmöffnung strömungsverbundener oberer Teilkühlraum angeordnet ist, wobei vom unteren Teilkühlraum ein mit einer Drucksenke verbindbarer Kühlmittelaustritt ausgeht.The invention relates to a liquid-cooled internal combustion engine with a cylinder housing for at least one cylinder and at least one cylinder head, wherein the at least one cylinder in the cylinder housing is surrounded by a cooling jacket and wherein in the cylinder head connected to the cylinder head adjacent to a fire deck lower part of the cooling room and with this over at least one overflow opening is arranged flow-connected upper part of the cooling chamber, wherein from the lower part of the cooling chamber emanates a connectable to a pressure sink coolant outlet.

Aus der AT 005.939 U1 ist ein Zylinderkopf für eine flüssigkeitsgekühlte Brennkraftmaschine mit einer an ein Feuerdeck grenzenden Kühlraumanordnung bekannt, welche durch ein im Wesentlichen parallel zum Feuerdeck ausgebildetes Zwischendeck in einen feuerdeckseitigen unteren Teilkühlraum und einen an diesen in Richtung der Zylimderachse anschließenden oberen Teilkühlraum unterteilt ist. Der untere und der obere Teilkühlraum sind durch zumindest eine Überströmöffnung miteinander strömungsverbunden. In dem oberen Teilkühlraum mündet ein mit einer Druckquelle verbindbarer Kühlmitteleintritt ein, vom unteren Teilkühlraum geht ein mit einer Drucksenke verbindbarer Kühlmittelaustritt aus. Somit strömt das Kühlmittel im Motorbetrieb von der Druckquelle kommend in den oberen Teilkühlraum und von diesem über die Überströmöffnung in den unteren Teilkühlraum und von dieser zur Drucksenke. Weiters strömt das Kühlmittel vom unteren Teilkühlraum über Verbindungsöffnungen im Feuerdeck in den Kühlmantel des Zylindergehäuses. Nachteilig ist, dass der Bereich der Zylinderbuchsen zu schwach gekühlt wird. Ein weiterer Nachteil ist, dass die Strömungsrichtung vom oberen Teilkühlraum über den unteren Teilkühlraum in den Kühlmantel des Zylindergehäuses entgegen der Thermosyphonwirkung im gesamten Kühlsystem erfolgt, was den Durchfluss des Kühlmittels speziell im Notbetrieb nachteilig beeinflusst.From the AT 005,939 U1 is a cylinder head for a liquid-cooled internal combustion engine with a bordering on a fire deck cooling space arrangement known, which is divided by a substantially parallel to the fire deck formed intermediate deck in a Feuerdeckseitigen lower part of the refrigerator and a subsequent thereto in the direction of Zylimderachse upper part of the refrigerator. The lower and the upper part of the cooling chamber are fluidly connected to each other by at least one overflow. In the upper part of the cooling chamber opens a connectable to a pressure source coolant inlet, from the lower part of the cooling chamber is a connectable to a pressure sink coolant outlet. Thus, during engine operation, the coolant flows from the pressure source into the upper partial cooling space and from there via the overflow opening into the lower part cooling space and from there to the pressure sink. Furthermore, the coolant flows from the lower part of the cooling chamber via connection openings in the fire deck in the cooling jacket of the cylinder housing. The disadvantage is that the area of the cylinder liners is cooled too weakly. Another disadvantage is that the direction of flow from the upper part of the cooling chamber via the lower part of the cooling chamber in the cooling jacket of the cylinder housing against the Thermosyphonwirkung throughout the cooling system takes place, which adversely affects the flow of the coolant, especially in emergency operation.

Aufgabe der Erfindung ist es, diese Nachteile zu vermeiden und unter Nutzung der physikalischen Thermosyphonwirkung eine verbesserte Kühlung von thermisch kritischen Bereichen, insbesondere des unteren Teilkühlraums des Zylinderkopfes und der Zylinderbuchsen, zu erreichen.The object of the invention is to avoid these disadvantages and to achieve improved cooling of thermally critical areas, in particular the lower part of the cooling chamber of the cylinder head and the cylinder liners using the physical Thermosyphonwirkung.

Erfindungsgemäß wird dies dadurch erreicht, dass in den Kühlmantel des Zylindergehäuses zumindest ein mit einer Druckquelle verbindbarer Kühlmitteleintritt einmündet und dass der Kühlmantel über zumindest einen Steigkanal direkt mit dem oberen Teilkühlraum strömungsverbunden ist, so dass Kühlmittel im Motorbetrieb von der Druckquelle in den Kühlmantel des Zylindergehäuses und von diesem in den oberen Teilkühlraum des Zylinderkopfes und weiter über die Überströmöffnung in den unteren Teilkühlraum und von diesem zur Drucksenke strömt. Dabei ist vorgesehen, dass das Kühlmittel von einer Druckquelle kommend in den Kühlmantel des Zylindergehäuses eingebracht und von diesem direkt dem oberen Teilkühlraum zugeführt wird und dass das Kühlmittel vom oberen Teilkühlraum über zumindest eine Überströmöffnung pro Zylinder in den unteren Teilkühlraum zugeführt und weiter vom unteren Teilkühlraum einer Drucksenke außerhalb der Brennkraftmaschine zugeführt wird, wobei vorzugsweise das Kühlmittel pro Zylinder den Kühlraum, den oberen Teilkühlraum und den unteren Teilkühlraum im Wesentlichen in Motorquerrichtung durchströmt.According to the invention this is achieved in that in the cooling jacket of the cylinder housing at least one connectable to a pressure source coolant inlet opens and that the cooling jacket via at least one riser directly connected to the upper part cooling space, so that coolant in engine operation flows from the pressure source into the cooling jacket of the cylinder housing and from this into the upper part of the cooling chamber of the cylinder head and further via the overflow in the lower part of the cooling chamber and from there to the pressure sink. It is envisaged that the coolant is introduced from a pressure source coming into the cooling jacket of the cylinder housing and fed directly from this to the upper part of the cooling chamber and that the coolant from the upper part of the cooling chamber via at least one overflow per cylinder fed into the lower part of the refrigerator and further from the lower part of a refrigerator Pressure sink outside of the internal combustion engine is supplied, wherein preferably the coolant per cylinder flows through the cooling chamber, the upper part of the cooling chamber and the lower part of the cooling chamber substantially in the engine transverse direction.

Besonders vorteilhaft ist es, wenn an einer Längsseite des Zylindergehäuses ein Kühlmittelverteilerraum angeordnet ist, wobei vorzugsweise der Kühlmantel über zumindest einen Kühlmitteleintritt pro Zylinder mit dem Verteilerraum strömungsverbunden ist. Um eine gleichmäßige Zuströmung des Kühlmittels in den oberen Teilkühlraum zu erreichen, ist vorgesehen, dass der Zylinderkopf an beiden Längsseiten Steigkanäle zur Strömungsverbindung des Kühlmantels mit dem oberen Teilkühlraum aufweist, wobei vorzugsweise pro Zylinder zumindest zwei an gegenüberliegenden Längsseiten angeordnete Steigkanäle vorgesehen sind.It is particularly advantageous if a coolant distributor space is arranged on one longitudinal side of the cylinder housing, wherein preferably the cooling jacket is flow-connected to the distributor chamber via at least one coolant inlet per cylinder. In order to achieve a uniform inflow of the coolant in the upper part of the cooling chamber, it is provided that the cylinder head has on both longitudinal sides risers for flow connection of the cooling jacket with the upper part of the cooling chamber, preferably at least two arranged on opposite longitudinal sides riser channels are provided per cylinder.

In Weiterführung der Erfindung kann vorgesehen sein, dass der Kühlmantel über Bypassöffnungen mit definiertem Strömungsquerschnitt mit dem unteren Teilkühlraum direkt verbunden ist, wobei die Bypassöffnungen durch Strömungsübertritte in der Zylinderkopfdichtung gebildet sind. Dadurch können eventuell im Kühlmantel entstehende Dampfblasen unmittelbar in den unteren Teilkühlraum des Zylinderkopfes abgeleitet werden. Weiters kann durch die Bypassöffnungen eine gezielte Kühlung von thermisch kritischen Bereichen, beispielsweise im Bereich der Auslassventilstege, im Notbetrieb bewirkt werden.In a continuation of the invention it can be provided that the cooling jacket is directly connected via bypass openings with defined flow cross-section with the lower part of the cooling chamber, wherein the bypass openings are formed by flow in the cylinder head gasket. As a result, possibly resulting in the cooling jacket steam bubbles can be discharged directly into the lower part of the cooling chamber cylinder head. Furthermore, targeted cooling of thermally critical regions, for example in the region of the outlet valve webs, in emergency operation can be effected by the bypass openings.

Eine ausgeprägte Querströmung des Kühlmittels wird erreicht, wenn pro Zylinder ein unterer Teilkühlraum vorgesehen ist, wobei die unteren Teilkühlräume zwei benachbarter Zylinder voneinander getrennt sind. Jeder untere Teilkühlraum kann dabei über zumindest einen Kühlmittelaustritt mit einem an einer Längsseite des Zylinderkopfes angeordneten Kühlmittelsammler verbunden ist. Der obere Teilkühlraum kann dagegen für mehrere Zylinder in Längsrichtung durchgehend ausgebildet sein.A pronounced cross-flow of the coolant is achieved if one lower partial cooling space is provided per cylinder, the lower part cooling spaces of two adjacent cylinders being separated from one another. Each lower part of the cooling chamber can be connected via at least one coolant outlet with a arranged on a longitudinal side of the cylinder head coolant collector. The upper part of the cooling chamber, however, may be formed continuously for several cylinders in the longitudinal direction.

Um eine Dampfansammlung im oberen Teilkühlraum zu vermeiden, ist es vorteilhaft, wenn der obere Teilkühlraum über zumindest eine Entdampfungsöffnung mit geringem Querschnitt mit dem Kühlmittelsammelraum strömungsverbunden ist. Alternativ dazu ist es auch möglich, denn oberen Teilkühlraum über eine Entdampfungsöffnung mit einem Ausgleichsbehälter des Kühlsystems zu verbinden.In order to avoid a vapor accumulation in the upper part of the cooling chamber, it is advantageous if the upper part of the cooling chamber flow connected via at least one Entdampfungsöffnung with a small cross section with the coolant collecting space is. Alternatively, it is also possible to connect the upper part of the cooling chamber via a Entdampfungsöffnung with a surge tank of the cooling system.

Die Erfindung wird im Folgenden anhand der Figuren näher erläutert. Es zeigen:

The invention will be explained in more detail below with reference to FIGS. Show it:

Die Brennkraftmaschine 1 weist ein Zylindergehäuse 2 und einen Zylinderkopf 3 auf. Zur Kühlung ist ein Kühlsystem 4 mit einer Kühlflüssigkeit vorgesehen, welche einen Kühlmantel 5 im Zylindergehäuse 2 und obere, sowie untere Teilkühlräume 6, 7 im Zylinderkopf 3 durchströmt. Der obere Teilkühlraum 6 und der untere Teilkühlraum 7 sind dabei über zumindest eine Überströmöffnung 8, 9 pro Zylinder miteinander strömungsverbunden. An gegenüberliegenden Längsseiten 3a, 3b des Zylinderkopfes 3 sind Steigkanäle 10, 11 angeordnet, welche den oberen Teilkühlraum 6 mit dem Kühlmantel 5 des Zylindergehäuses 2 verbinden. Der Kühtmantel 5 des Zylindergehäuses 2 ist über zumindest einen Kühlmitteleintritt 12 pro Zylinder 13 mit einem sich über eine Längsseite-3a erstreckenden Kühlmittelverteilerraum 20 verbunden. Der untere Teilkühlraum 7 mündet über zumindest einen Kühlmittelaustritt 14 pro Zylinder 13 in einen an der Längsseite 3a des Zylinderkopfes 3 angeordneten Kühlmittelsammelraum 15 ein. Weiters können Bypassöffnungen 16, 17 im Feuerdeck 18 angeordnet sein, die den Kühlmantel 5 direkt mit dem unteren Teilkühlraum 7 verbinden. Die Bypassöffnungen 16, 17 weisen einen durch Strömungsübertritte in der Zylinderkopfdichtung 21 gebildete, genau definierten Überströmquerschnitt auf, so dass nur eine relativ kleine Kühlmittelmenge direkt in den unteren Teilkühlraum 7 überströmen kann.The internal combustion engine 1 has a cylinder housing 2 and a cylinder head 3. For cooling, a cooling system 4 is provided with a cooling liquid which flows through a cooling jacket 5 in the cylinder housing 2 and upper and lower part cooling chambers 6, 7 in the cylinder head 3. The upper part of the cooling chamber 6 and the lower part of the cooling chamber 7 are fluidly connected to each other via at least one overflow 8, 9 per cylinder. On opposite longitudinal sides 3a, 3b of the cylinder head 3 riser channels 10, 11 are arranged, which connect the upper part of the cooling chamber 6 with the cooling jacket 5 of the cylinder housing 2. The Kühtmantel 5 of the cylinder housing 2 is connected via at least one coolant inlet 12 per cylinder 13 with a extending over a longitudinal side-3a coolant distribution chamber 20. The lower part of the cooling chamber 7 opens via at least one coolant outlet 14 per cylinder 13 in a arranged on the longitudinal side 3a of the cylinder head 3 coolant collecting space 15 a. Furthermore, bypass openings 16, 17 may be arranged in the fire deck 18, which connect the cooling jacket 5 directly to the lower part cooling space 7. The bypass openings 16, 17 have a precisely defined overflow cross section formed by flow passages in the cylinder head gasket 21, so that only a relatively small amount of coolant can flow directly into the lower part cooling space 7.

Um eine Dampfansammlung im oberen Teilkühlraum 6 zu vermeiden, ist es vorteilhaft, wenn der obere Teilkühlraum 6 über eine Entdampfungsöffnung 22 mit geringem Querschnitt mit dem Kühlmittelsammelraum 15 an zumindest einem Zylinder strömungsverbunden ist.In order to avoid accumulation of steam in the upper part of the cooling chamber 6, it is advantageous if the upper part of the cooling chamber 6 is fluidly connected via a Entdampfungsöffnung 22 with a small cross section with the coolant collection chamber 15 at least one cylinder.

Das Kühlmittel strömt entsprechend den Pfeilen P von einer nicht weiter dargestellten Kühlmittelpumpe kommend in den Kühlmittelverteilerraum 20 und gelangt großteils über Kühlmitteleintritte 12 in den Kühlmantel 5 um die Zylinderbuchsen 13, bzw. über den Steigkanal 10 direkt in den oberen Teilkühlraum. Das Zylindergehäuse 2 wird vom Kühlmittel in Querrichtung durchströmt. Das Kühlmittel gelangt weiters über die Steigkanäle 10, 11 in den oberen Teilkühlraum 6, wobei der Anteil der Kühlmittelmenge durch den Kühlmantel 5 durch die geometrische Gestaltung der Steigkanäle 10, 11 und entsprechender Dichtungsöffnungen eingestellt werden kann. Das gesamte Kühlmittel-wird über die Überströmöffnungen 8, 9 in den unteren Teilkühlraum 7 geführt. Der untere Teilkühlraum 7 wird - wie der obere Teilkühlraum 6 - im Wesentlichen in radialer Richtung quer zum Motor durchströmt, wobei das Kühlmittel über die Kühlmittelaustritte 14 an der Längsseite 3a des Zylinderkopfes 3 in den Kühlmittelsammelraum 15 gelangt. Vom Kühlmittelsammelraum 15 wird das Kühlmittel zu einem Flüssigkeitskühler 19 und schließlich über die Kühlmittelpumpe wieder dem Kühlmittelverteilerraum 20 zugeführt.The coolant flows according to the arrows P coming from a coolant pump not shown coming into the coolant distribution chamber 20 and largely passes through coolant inlet 12 into the cooling jacket 5 to the cylinder liners 13, and via the riser 10 directly into the upper part of the refrigerator. The cylinder housing 2 is traversed by the coolant in the transverse direction. The coolant also passes through the riser channels 10, 11 in the upper part of the cooling chamber 6, wherein the proportion of the amount of coolant through the cooling jacket 5 by the geometric configuration of the riser channels 10, 11 and corresponding sealing openings can be adjusted. The entire coolant is guided via the overflow openings 8, 9 in the lower part of the cooling chamber 7. The lower part of the cooling chamber 7 is - as the upper part of the cooling chamber 6 - flows through transversely to the engine substantially in the radial direction, wherein the coolant passes through the coolant outlets 14 on the longitudinal side 3 a of the cylinder head 3 in the coolant collecting space 15. From the coolant collection chamber 15, the coolant is supplied to a liquid cooler 19 and finally via the coolant pump again to the coolant distribution chamber 20.

Sie kann aber auch bei Einzylindermotoren angewendet werden.The invention has been described with reference to an internal combustion engine having a plurality of cylinders and a continuous cylinder head. But it can also be applied to single-cylinder engines.
