Description

Kühlkreislauf für eine Brennkraftmaschine mit getrennter Durchströmung von Zylinderkopf und Zylinderkurbelgehäuse, und einem Abgaskühler.Cooling circuit for an internal combustion engine with separate flow through the cylinder head and cylinder crankcase, and an exhaust gas cooler.

Derartige Kühlkreisläufe werden im Kraftfahrzeugbau zur Wärmeabfuhr von der Brennkraftmaschine und zur Kühlung von Betriebsstoffen der Brennkraftmaschine, wie beispielsweise Abgas, Frischgas oder Schmiermittel genutzt, wodurch sich der Wirkungsgrad und/oder die Abgaszusammensetzung der Brennkraftmaschine beeinflussen lässt.Such cooling circuits are used in the automotive industry for heat dissipation of the internal combustion engine and for cooling of operating materials of the internal combustion engine, such as exhaust gas, fresh gas or lubricant, which can affect the efficiency and / or the exhaust gas composition of the internal combustion engine.

Die DE 10 2004 052 137 A1 zeigt eine Zweikreiskühlung für eine Brennkraftmaschine mit einem Kurbelgehäuse und einem Zylinderkopf. Das Kurbelgehäuse ist in einen Kurbelgehäuse-Kühlmittelkreislauf eingebunden, während der Zylinderkopf in einen separaten Zylinderkopf-Kühlmittelkreislauf eingebunden ist. Beide Kühlmittelkreisläufe werden von einer gemeinsamen Kühlmittelpumpe gespeist. Der Kurbelgehäuse-Kühlmittelkreislauf kann durch ein Stellelement verschlossen werden, wodurch sich das Kurbelgehäuse nach einem Kaltstart schneller erwärmt. Weiterhin ist es möglich die beiden Kühlmittelkreisläufe auf unterschiedlichen Temperaturniveaus zu betreiben.The DE 10 2004 052 137 A1 shows a dual-circuit cooling for an internal combustion engine with a crankcase and a cylinder head. The crankcase is incorporated in a crankcase coolant circuit while the cylinder head is incorporated into a separate cylinder head coolant circuit. Both coolant circuits are fed by a common coolant pump. The crankcase coolant circuit can be closed by an actuator, whereby the crankcase heats up faster after a cold start. Furthermore, it is possible to operate the two coolant circuits at different temperature levels.

Die DE 103 32 947 A1 beschreibt ebenfalls eine Brennkraftmaschine für ein Kraftfahrzeug mit einer Zweikreiskühlung, bei der Zylinderkopf und Zylinderkurbelgehäuse über separate Kühlmittelzweige verfügen, die über einen gemeinsamen Zulauf von einer Kühlmittelpumpe gespeist werden. Das Kühlmittel auf dem Zylinderkopf und dem Zylinderkurbelgehäuse wird nach dem Austritt aus den entsprechenden Bauteilen wieder zusammengeführt und zur Kühlmittelpumpe rezirkuliert. Dabei kann das Kühlmittel wahlweise über einen Zweig mit Abgaskühler, Heizungswärmetauscher und Ölkühler zur Kühlmittelpumpe geführt werden oder aber über einen zweiten Zweig wahlweise zum Hauptwärmetauscher oder unter Umgehung des Hauptwärmetauschers direkt zur Kühlmittelpumpe geleitet werden.The DE 103 32 947 A1 also describes an internal combustion engine for a motor vehicle with a dual-circuit cooling, in the cylinder head and cylinder crankcase have separate coolant branches, which are fed via a common inlet from a coolant pump. The coolant on the cylinder head and the cylinder crankcase is recombined after exiting the corresponding components and recirculated to the coolant pump. In this case, the coolant can optionally be performed via a branch with exhaust gas cooler, heater core and oil cooler to the coolant pump or passed through a second branch either to the main heat exchanger or bypassing the main heat exchanger directly to the coolant pump.

Nachteilig ist jedoch, dass der Abgaskühler bei dem gezeigten Kühlmittelkreislauf nur mit solchem Kühlmittel beaufschlagt werden kann, welches bereits den gesamten Motor, also sowohl den Zylinderkopf, als auch das Zylinderkurbelgehäuse, durchströmt hat und dementsprechend erwärmt ist. Dadurch ergeben sich Wirkungsgradverluste bei der Kühlung des Abgases. Zudem benötigt die Integration von zwei verschiedenen Zweigen zur Rückführung des Kühlmittels zur Kühlmittelpumpe einen großen Bauraum.The disadvantage, however, is that the exhaust gas cooler can be acted upon in the coolant circuit shown only with such coolant, which has already flowed through the entire engine, so both the cylinder head, and the cylinder crankcase, and is heated accordingly. This results in efficiency losses in the cooling of the exhaust gas. In addition, the integration of two different branches for returning the coolant to the coolant pump requires a large amount of space.

Aufgabe der vorliegenden Erfindung ist es daher einen Kühlkreislauf für eine Brennkraftmaschine bereitzustellen, in dem ein Abgaskühler mit geringem Bauraumbedarf angeordnet und möglichst effizient betrieben werden kann.The object of the present invention is therefore to provide a cooling circuit for an internal combustion engine, in which an exhaust gas cooler with a small space requirement can be arranged and operated as efficiently as possible.

Diese Aufgabe wird durch die Merkmale des Patentanspruchs 1 gelöst.This object is solved by the features of patent claim 1.

Indem der Abgaskühler stromab des Zylinderkopfes und stromauf der Verbindungsstelle in den Zylinderkopf-Zweigkreislauf eingebunden ist, wird dieser von dem im Vergleich zum Kurbelgehäuse-Zweigkreislauf kühleren Kühlmittel des Zylinderkopf-Zweigkreislaufs durchströmt. Dadurch kann der Betriebsstoff in dem entsprechenden Wärmetauscher besser gekühlt werden, was sich positiv auf den Wirkungsgrad und/oder die Abgaszusammensetzung der Brennkraftmaschine auswirkt. Natürlich können neben den genannten Bestandteilen des Kühlkreislaufs auch noch weitere Elemente, wie ein Heizungswärmetauscher, je nach Bedarf integriert werden.By the exhaust gas cooler is integrated downstream of the cylinder head and upstream of the junction in the cylinder head branch circuit, this is flowed through by the compared to the crankcase branch circuit cooler coolant of the cylinder head branch circuit. As a result, the fuel in the corresponding heat exchanger can be better cooled, which has a positive effect on the efficiency and / or the exhaust gas composition of the internal combustion engine. Of course, in addition to the aforementioned components of the cooling circuit also other elements, such as a heat exchanger, can be integrated as needed.

Ein als unterdruckbetätigtes Drehventil ausgebildetes Absperrventil ist im Kurbelgehäuse-Zweigkreislauf stromab des Kurbelgehäuses angeordnet. Durch das Absperrventil kann der Kühlmittelvolumenstrom im Kurbelgehäuse-Zweigkreislauf reguliert werden. So kann durch eine Absperrung des Kurbelgehäuse-Zweigkreislaufs vorzugsweise nach dem Start der Brennkraftmaschine eine schnellere Erwärmung derselben erzielt werden.A shut-off valve designed as a vacuum-operated rotary valve is arranged in the crankcase branch circuit downstream of the crankcase. Through the shut-off valve, the coolant flow in the crankcase branch circuit can be regulated. Thus, by a shut-off of the crankcase branch circuit preferably after the start of the internal combustion engine, a faster heating of the same can be achieved.

In einer bevorzugten Ausführung ist der Hauptwärmetauscher stromab der Verbindungsstelle angeordnet. Der Hauptwärmetauscher hat die größte Kühlkapazität und kann mit Kühlmittel aus dem Zylinderkopf und dem Kurbelgehäuse beaufschlagt werden.In a preferred embodiment, the main heat exchanger is arranged downstream of the connection point. The main heat exchanger has the largest cooling capacity and can be supplied with coolant from the cylinder head and the crankcase.

In einer bevorzugten Ausführung ist ein Steuerventil zwischen Kühlmittelpumpe und Hauptwärmetauscher angeordnet. Das Steuerventil reguliert den der Kühlmittelpumpe zuzuführenden Kühlmittelvolumenstrom.In a preferred embodiment, a control valve between the coolant pump and main heat exchanger is arranged. The control valve regulates the coolant flow to be supplied to the coolant pump.

In einer bevorzugten Ausführung zweigt zwischen Hauptwasserkühler und Verbindungsstelle eine Bypassleitung ab, die an dem Steuerventil angebunden ist. Die Bypassleitung dient der bedarfsweisen Umgehung des Hauptwärmetauschers, indem das Kühlmittel aus dem Zylinderkopf und dem Kurbelgehäuse stromab der Verbindungsstelle abgezweigt wird und dem Steuerventil zugeführt wird. Das Steuerventil kann temperaturabhängig zwischen der Durchströmung der Bypassleitung oder des Hauptwärmetauschers umschalten. Dazu ist das Steuerventil bevorzugt als ein Kennfeldthermostat ausgebildet.In a preferred embodiment, a bypass line branches off between the main water cooler and the connection point and is connected to the control valve. The bypass line is used for bypassing the main heat exchanger by the coolant is diverted from the cylinder head and the crankcase downstream of the junction and the control valve is supplied. The control valve can switch depending on the temperature between the flow through the bypass line or the main heat exchanger. For this purpose, the control valve is preferably designed as a map thermostat.

In einer bevorzugten Ausführung werden zwei oder mehr Zylinderköpfe im Zylinderkopf-Zweigkreislauf parallel durchströmt und der Abgaskühler ist stromab der Zylinderköpfe angeordnet. Bei Brennkraftmaschinen mit Zylinderbänken in V- oder W-Anordnung finden sich mehrere Zylinderköpfe. Diese sind parallel in den Zylinderkopf-Zweigkreislauf eingebunden, wobei das Kühlmittel aus den Zylinderköpfen vor der Zuführung in den Abgaskühler wieder gesammelt wird.In a preferred embodiment, two or more cylinder heads are flowed through in parallel in the cylinder head branch circuit and the exhaust gas cooler is arranged downstream of the cylinder heads. In internal combustion engines with cylinder banks in V or W arrangement, there are several cylinder heads. These are incorporated in parallel in the cylinder head branch circuit, wherein the coolant is collected from the cylinder heads before being fed into the exhaust gas cooler again.

In einem nicht erfindungsgemäßen Beispiel ist der Wärmetauscher für einen Betriebsstoff als Ladeluftkühler ausgebildet. Ein Ladeluftkühler dient der Abkühlung von durch einen Lader verdichteter Frischluft, wodurch sich Wirkungsgradgewinne erzielen lassen.In an example not according to the invention, the heat exchanger for a fuel is designed as a charge air cooler. An intercooler is used to cool fresh air compressed by a supercharger, which results in efficiency gains.

Erfindungsgemäß ist der Wärmetauscher für einen Betriebsstoff als Abgaskühler ausgebildet. In einem Abgaskühler wird zumindest ein Teil des aus der Brennkraftmaschine austretenden Abgases gekühlt, um es als Inertgas dem Verbrennungsprozess in der Brennkraftmaschine zuzuführen (Abgasrückführung). Die daraus resultierende Verringerung der Verbrennungstemperatur reduziert den Anteil an Stickoxiden im Abgas.According to the invention, the heat exchanger for a fuel is designed as an exhaust gas cooler. In an exhaust gas cooler, at least part of the exhaust gas exiting the internal combustion engine is cooled to supply it as an inert gas to the combustion process in the internal combustion engine (exhaust gas recirculation). The resulting reduction in the combustion temperature reduces the proportion of nitrogen oxides in the exhaust gas.

Weitere Einzelheiten, Merkmale und Vorteile der Erfindung ergeben sich aus der nachstehenden Beschreibung eines bevorzugten Ausführungsbeispiels unter Bezugnahme auf die Zeichnung.Further details, features and advantages of the invention will become apparent from the following description of a preferred embodiment with reference to the drawings.

Darin zeigt die Figur eine schematische Ansicht des Kühlkreislaufs einer Brennkraftmaschine.Therein, the figure shows a schematic view of the cooling circuit of an internal combustion engine.

Gemäß der Figur hat eine Brennkraftmaschine 2 ein Kurbelgehäuse 4, welches Zylinder in einzelnen Brennräumen beinhaltet, und einen Zylinderkopf 3, der die für den Gaswechsel der Brennräume benötigten Vorrichtungen enthält. Die Brennkraftmaschine 2 setzt bei ihrem Betrieb chemische Energie in mechanische und thermische Energie um, weshalb diese in einen Kühlkreislauf 1 zur Wärmeabfuhr eingebunden ist. Bei der dargestellten Zweikreiskühlung fördert die Kühlmittelpumpe 5 Kühlmittel zur Brennkraftmaschine 2, wobei der Kühlmittelstrom sich an einer Verzweigungsstelle A in zwei parallele Zweigkreisläufe 8 und 9 aufteilt. Der Zylinderkopf 3 ist in einen Zylinderkopf-Zweigkreislauf 8 und das Kurbelgehäuse 4 in einen Kurbelgehäuse-Zweigkreislauf 9 eingebunden. Durch die in den Brennräumen des Kurbelgehäuses 4 hauptsächlich stattfindende Umsetzung der Energie, erwärmt sich das Kurbelgehäuse 4 beim Betrieb der Brennkraftmaschine 2 schneller und stärker als der Zylinderkopf 3. Die Zweigkreisläufe 8 und 9 werden stromab des Zylinderkopfes 3 beziehungsweise des Kurbelgehäuses 4 an einer Verbindungsstelle B wieder zusammengeführt. Im Zylinderkopf-Zweigkreislauf 8 ist zwischen Zylinderkopf 3 und Verbindungsstelle B ein Wärmetauscher 7 für ein Betriebsstoff der Brennkraftmaschine 2 angeordnet. Betriebsstoffe sind in diesem Zusammenhang Gase oder Flüssigkeiten, die für die Funktion der Brennkraftmaschine 2 benötigt werden, wie Abgas. Im Kurbelgehäuse-Zweigkreislauf 9 zwischen Kurbelgehäuse 4 und Verbindungsstelle B ist ein Absperrventil 10 angeordnet, wodurch der Kurbelgehäuse-Zweigkreislauf 9 zum Zwecke einer schnelleren Erwärmung der Brennkraftmaschine 2, insbesondere des Kurbelgehäuses 4, bedarfsweise abgesperrt werden kann. Das Absperrventil 10 ist als ein unterdruckbetätigtes Drehventil auszuführen. Von der Verbindungsstelle B gelangt das Kühlmittel zu einem Hauptwärmetauscher 6 und von diesem zu einem Steuerventil 11. Der Ausgang des Steuerventils 11 ist mit der Ansaugseite 5 der Kühlmittelpumpe 5 verbunden. Zwischen der Verbindungsstelle B und dem Hauptwärmetauscher 6 zweigt an einem Bypassabzweig C eine Bypassleitung 12 ab, durch die Kühlmittel aus der Brennkraftmaschine 2 unter Umgehung des Hauptwasserkühlers 6 zum Steuerventil 11 und somit zur Kühlmittelpumpe 5 gelangen kann. Das Steuerventil 11 ist zu diesem Zweck vorzugsweise als ein Kennfeldthermostat oder ein Drehschieber mit zwei Zuläufen und einem Ausgang auszuführen. Natürlich beschränkt sich der erfindungsgemäße Kühlkreislauf 1 nicht auf die dargestellten Elemente. Vielmehr können zusätzliche Heizungswärmetauscher, Ölkühler, Wasserkühler, etc. in den Kühlkreislauf 1 oder einen Teilkreislauf davon integriert werden.According to the figure , an internal combustion engine 2 has a crankcase 4, which contains cylinders in individual combustion chambers, and a cylinder head 3, which contains the devices required for the gas exchange of the combustion chambers. The internal combustion engine 2 converts chemical energy into mechanical and thermal energy during its operation, which is why it is integrated in a cooling circuit 1 for heat removal. In the illustrated two-circuit cooling, the coolant pump 5 conveys coolant to the internal combustion engine 2, wherein the coolant flow is divided at a branch point A into two parallel branch circuits 8 and 9. The cylinder head 3 is integrated into a cylinder head branch circuit 8 and the crankcase 4 into a crankcase branch circuit 9. As a result of the conversion of the energy mainly taking place in the combustion chambers of the crankcase 4, the crankcase 4 heats up faster and more vigorously than the cylinder head 3 during operation of the internal combustion engine 2. The branch circuits 8 and 9 are located downstream of the cylinder head 3 and the crankcase 4 at a connection point B. merged again. In the cylinder head branch circuit 8, a heat exchanger 7 for a fuel of the internal combustion engine 2 is arranged between the cylinder head 3 and junction B. Operating materials in this context are gases or liquids that are required for the function of the internal combustion engine 2, such as exhaust gas. In the crankcase branch circuit 9 between the crankcase 4 and junction B, a check valve 10 is arranged, whereby the crankcase branch circuit 9 for the purpose of faster heating of the internal combustion engine 2, in particular the crankcase 4, if necessary, can be shut off. The check valve 10 is to be executed as a negative pressure operated rotary valve. From the junction B, the coolant passes to a main heat exchanger 6 and from there to a control valve 11. The output of the control valve 11 is connected to the suction side 5 of the coolant pump 5. Between the connection point B and the main heat exchanger 6 branches off at a bypass branch C from a bypass line 12, can pass through the coolant from the internal combustion engine 2, bypassing the main water cooler 6 to the control valve 11 and thus to the coolant pump 5. For this purpose, the control valve 11 is preferably designed as a map-controlled thermostat or a rotary valve with two inlets and one outlet. Of course, the cooling circuit 1 of the invention is not limited to the elements shown. Rather, additional heat exchanger, oil cooler, water cooler, etc. can be integrated into the cooling circuit 1 or a partial circuit thereof.
