Abstract

Two channel systems are formed in the cylinder block of the internal combustion engine, an upper channel system assigned to the combustion spaces and a lower channel system separate from the upper channel system. The upper channel system carries coolant at a relatively high temperature and, at the cylinder block outlet, is connected to heat exchangers for vehicle heating, preheating of the oil and preheating of the intake air. The cooler coolant of the lower channel system is passed through the cylinder head before it recirculates back to the radiator.

Description

Kühlsystem für eine Cooling system for one

Kolben-Brennkraftmaschine Die Erfindung betrifft ein Kühlsystem für eine flüssigkeitsgekühlte Kolben-Brennkraftmaschine nach dem Oberbegriff des Anspruchs 1. Piston internal combustion engine The invention relates to a cooling system for a liquid-cooled piston internal combustion engine according to the preamble of the claim 1.

Aus DE-PS 908 930 ist eine flüssigkeitsgekühlte Brennkraftmaschine bekannt, bei der zwei getrennte Kühlkreisläufe für den Zylinderblock'und den Zylinderdeckel vorgesehen sind. Die Temperatur im Kühlkreislauf des Zylinderdeckels wird niederer gehalten als die Temperatur des Zylinderblock-Kühlkreislaufs.DE-PS 908 930 discloses a liquid-cooled internal combustion engine known, in which two separate cooling circuits for the cylinder block and the cylinder cover are provided. The temperature in the cooling circuit of the cylinder cover is lower held as the temperature of the cylinder block cooling circuit.

Es wird dadurch eine intensivere Kühlung des Einlaßkanals und Brennraumes bezweckt, um insbesondere bei hoher Belastung der Brennkraftmaschine eine stärkere Füllung des Brennraumes und eine Verbesserung des Liefergrades zu erreichen. Mit der verhältsnismäßig hohen Temperatur des Zylinderblocks sollen die Reibungsverluste verringert und der mechanische Wirkungsgrad erhöht werden. Nachteilig bei diesem Kühlsystem ist der hohe Kostenaufwand, da ein doppeltes Rohrleitungsnetz mit zwei Pumpen und zwei Kühlern benötigt werden.This results in more intensive cooling of the inlet duct and combustion chamber aims to provide a stronger, especially when the internal combustion engine is under high load To achieve filling of the combustion chamber and an improvement in the degree of delivery. With the relatively high temperature of the cylinder block should reduce the friction losses can be reduced and the mechanical efficiency increased. Disadvantage of this Cooling system is the high cost, as a double pipeline network with two Pumps and two coolers are required.

Es ist die Aufgabe der Erfindung, eine unterschiedlich starke Kühlung des unteren Zylinderblocks und der Brennräume, insbesondere einer Mehrzylinder-Kolbenbrennkraftmaschine mit geringeren Material- und Montagekosten zu erreichen.It is the object of the invention to provide different levels of cooling of the lower cylinder block and the combustion chambers, in particular of a multi-cylinder piston internal combustion engine to achieve with lower material and assembly costs.

Zur Lösung dieser Aufgabe dienen die im Kennzeichen des Anspruchs 1 aufgeführten Merkmale. Während- bei bekannten Mehrzylinder-Brennkraftmaschinen die Kühlräume des Zylinderblocks ein einziges, zusammenhängendes Kanalsystem bilden, in dem der ganze Kühlmittel strom durch Temperaturleitung und Konvektion auf annähernd gleicher Temperatur gehalten wird, sind nun erfindungsgemäß im Zylinderblock zwei getrennte Kanalsysteme mit unterschiedlichem Temperaturniveau des in ihnen strömenden Kühlmittels geschaffen. Das obere, die Brennräume umgebende Kanalsystem hat infolge stärkerer Beheizung durch die Brennräume und einer geringeren Durchfluß stärke des Kühlmittels eine bedeutend höhere Temperatur als das untere, der ölwanne benachbarte Kanalsystem. um diesen gewünschten Effekt zu exzielen, ist lediglich eine Trennwand im Zylinderblock einzugießen oder einzukleben, wodurch die Fertigungskosten gegenüber herkömmlichen Ausführungen nur unwesentlich erhöht werden.To solve this problem are used in the characterizing part of the claim 1 listed features. While in known multi-cylinder internal combustion engines the cooling chambers of the cylinder block form a single, coherent channel system, in which the entire coolant flow through temperature conduction and convection is kept at approximately the same temperature, are now according to the invention in the cylinder block two separate duct systems with different temperature levels in them flowing coolant created. The upper duct system surrounding the combustion chambers has due to stronger heating by the combustion chambers and a lower flow strength of the coolant a significantly higher temperature than the lower one, the oil pan neighboring sewer system. to achieve this desired effect is merely Pour or glue a partition in the cylinder block, reducing manufacturing costs are only slightly increased compared to conventional designs.

Die beiden Kanalsysteme können auch in einen vorgefertigten Einsatz eingearbeitet sein, der in den Zylinderblock eingepreßt wird. Auf diese Weise lassen sich die Kanalsysteme maßhaltig und ohne Totwassergebiete herstellen, so daß insgesamt geringere Mengen an Kühlmittel benötigt werden, eine kleinere Kühlmittelpumpe verwendet werden kann und eine Gewichtsersparnis erzielt wird.The two duct systems can also be used in a prefabricated manner be incorporated, which is pressed into the cylinder block. Leave that way the canal systems produce dimensionally stable and without dead water areas, so that overall If smaller amounts of coolant are required, a smaller coolant pump is used can be and a weight saving is achieved.

In weiterer Ausgestaltung der Erfindung wird das heiße Kühler mittel des oberen Kanalsystems zur Fahrzeugheizung, Vorwärmung der Verbrennungsluft oder zur ölvorwärmung benutzt.In a further embodiment of the invention, the hot cooler is medium the upper duct system for vehicle heating, preheating of the combustion air or used for oil preheating.

Diese Erwärmungsvorgänge können wesentlich schneller ablaufen als auf herkömmliche Art, da mit erhöhter Temperatur gefahren wird. Es wird eine Verkürzung der Warmlaufphase der Brennkraftmaschine und somit eine Kraftstoffeinsparung erzielt.These heating processes can take place much faster than in the conventional way, as the temperature is increased. It will be a shortening the warm-up phase of the internal combustion engine and thus a fuel saving achieved.

Das kältere Kühlmittel des unteren Kanalsystems wird nach Austritt aus dem Zylinderblock durch den Zylinderkopf geleitet, bevor es zum Kühler zurückfließt.The colder coolant of the lower duct system is discharged from the cylinder block through the cylinder head before flowing back to the radiator.

Das erfindungsgemäße Kühlsystem ist in der Zeichnung dargestellt und wird nachfolgend erläutert. Es zeigen: Fig. 1 Gehäuse einer Brennkraftmaschine mit Kühlmittelleitungen, Fig. 2 Schnitt durch den Zylinderblock nach Linie II-II der Fig. 1.The cooling system according to the invention is shown in the drawing and is explained below. They show: FIG. 1 the housing of an internal combustion engine Coolant lines, Fig. 2 section through the cylinder block along line II-II of the Fig. 1.

Pas obere Kanalsystem 4 ist über ein Drosselventil 7, das untere Kanalsystem 6 über ein Drosselventil 8 an eine Kühlmittelleitung 9 angeschlossen, die von einer Pumpe 10 ausgeht. Die Pumpe 10 fördert das Kühlmittel in Pfeilrichtung durch die Kanalsysteme 4, 6. Der Durchflußquerschnitt des oberen Kanalsystems 4 ist nur etwa halb so groß wie der Durchflußquerschnitt des unteren Kanalsystems 6.The housing of the piston internal combustion engine to be cooled consists of a cylinder block 1, a cylinder head 2 and an oil pan 3. In the cylinder block 1, an upper channel system 4 is cast in, to which the cooling spaces 4a, 4b, 4c, 4d, 4e are summarized, the combustion chambers in the cylinders 5a, 5d, 5c, 5d rings surround. The cooling spaces in the area of the lower part adjacent to the oil pan 3 the cylinders 5a, 5b, 5c, 5d form a lower channel system 6. Pas upper channel system 4 is via a throttle valve 7, the lower channel system 6 via a throttle valve 8 is connected to a coolant line 9 which originates from a pump 10. the Pump 10 conveys the coolant in the direction of the arrow through the channel systems 4, 6. The The flow cross-section of the upper channel system 4 is only about half as large as that Flow cross section of the lower channel system 6.

Infolge dessen ist oben die Durchfluß stärke auch nur halb so groß wie unten. Da zudem die Beheizung des oberen Kanalsystems 4 durch die Brennräume weit intensiver ist, ist die Kühlmitteltemperatur dort weit höher als im unteren Kanalsystem 6. Nach Durchlauf des Zylinderblocks 1 und der Drosselbohrung 7a wird dieses heiße Kühlmittel des oberen Kanalsystems 4 einem Wärmetauscher 11 der Fahrzeugheizung und zugleich einem parallel geschaltetem Wärmetauscher 12 für die ölvorwarmung zugeführt. In einer Leitung 13 strömt es zum Kühler 14 und von dort zur Pumpe zurück, die den Kreislauf aufrecht erhält. Das untere Kanalsystem 4 ist am Ausgang 8a des Zylinderblocks 1 an die Kühlräume des Zylinderkopfs 2 angeschlossen. Von dort strömt das Kühlmittel über eine Leitung 15 zum Kühler 14 zurück. Mit den Drosselventilen 7, 8 läßt sich die Durchflußstärke durch die beiden Kanalsysteme 4, 6 den jeweiligen Betriebsbedingungen der Brennkraftmaschine entsprechend. von Hand oder automatisch steuern. Zur Aufteilung des KUhlsystems in zwei Kanalsysteme 4, 6 unterschiedlicher Temperatur ist lediglich eine zwischenliegende Trennwand 16 erforderlich, die in Zylinderblock 1 eingegossen ist.As a result, the flow rate is only half as large above like below. There is also the heating of the upper duct system 4 through the combustion chambers is far more intense, the coolant temperature is far higher there than in the lower one Channel system 6. After passing through the cylinder block 1 and the throttle bore 7a this hot coolant of the upper duct system 4 to a heat exchanger 11 of the vehicle heater and at the same time fed to a heat exchanger 12 connected in parallel for preheating the oil.
