Description
Technisches GebietTechnical area
Die vorliegende Erfindung betrifft ein kombiniertes AGR- und Abgaskühler-Ventil sowie ein Abgasrückführsystem mit einem derartigen Ventil.The present invention relates to a combined EGR and exhaust gas cooler valve and an exhaust gas recirculation system with such a valve.
Stand der TechnikState of the art
Abgasrückführsysteme dienen der Reduzierung von Schadstoffausstoß und der Verbesserung der Effizienz von Verbrennungsmotoren. Hierbei kann beispielsweise bei aufgeladenen Dieselmotoren die Stickoxyderzeugung durch Rückführung des Abgases reduziert werden. In einem Abgasrückführsystem lenkt ein Abgasrückführventil einen Teil des Abgases aus dem Abgaskrümmer zurück zum Ansaugtrakt des Motors, wo es sich mit Frischluft vermischt. Nachteilig ist dabei, dass aufgrund der heißen rückgeführten Abgasluft die Ansaugluft des Motors insgesamt erwärmt wird, was zur Verringerung der Motorleistung führen kann. Aus diesem Grund wurden Motoren entwickelt, welche über einen oder mehrere AGR-Kühler verfügen, welche gesteuert durchströmt und ggf. selektiv geschaltet werden können, um unterschiedliche Kühlleistungen für unterschiedliche Motorzustände bereitzustellen.

Darstellung der ErfindungPresentation of the invention
Vor diesem Hintergrund liegt der Erfindung die Aufgabe zugrunde, ein kombiniertes AGR- und Abgaskühler-Ventil zu schaffen, durch das eine Vielzahl von Betriebszuständen realisierbar sind.Against this background, the invention has for its object to provide a combined EGR and exhaust gas cooler valve, through which a variety of operating conditions can be realized.
Die Lösung dieser Aufgabe erfolgt durch das im Patentanspruch 1 beschriebene Ventil.The solution to this problem is achieved by the valve described in claim 1.
Demzufolge weist diese zumindest einen Zufluss, zumindest zwei Abflüsse und zumindest eine weitere Öffnung auf, wobei zwischen dem Zufluss und einem Abfluss sowie zwischen dem Zufluss und der weiteren Öffnung jeweils ein durch ein federnd gelagertes Ventilelement verschließbarer Ventilsitz vorgesehen ist. Jeweils sind die Ventilelemente an einem gemeinsamen Schaft derart federnd gelagert, dass beide Ventilsätze verschließbar und einzeln öffenbar sind, während der andere geschlossen bleibt. Mit anderen Worten führt eine Bewegung des gemeinsamen Ventilschafts derart, dass einer der beiden Ventilsitze geöffnet wird, zu einer Kraft auf das andere Ventilelement in dessen Schließrichtung. Beim jeweiligen Öffnen stützt sich somit das geschlossene Ventilelement an seinem Ventilsitz ab, und typischerweise gegen eine Federkraft im Bereich dieses geschlossenen Ventilsitzes erfolgt eine Öffnung des anderen Ventils.Accordingly, this has at least one inflow, at least two outlets and at least one further opening, wherein between the inflow and an outflow and between the inflow and the further opening in each case a closable by a spring-mounted valve element valve seat is provided. In each case, the valve elements are resiliently mounted on a common shaft so that both sets of valves are closable and individually openable, while the other remains closed. In other words, a movement of the common valve stem such that one of the two valve seats is opened leads to a force on the other valve element in its closing direction. During the respective opening thus the closed valve element is supported on its valve seat, and typically takes place against a spring force in the region of this closed valve seat an opening of the other valve.
Hierdurch ist in dem Fall, dass beide Ventilsätze geschlossen sind, beispielsweise ein Betriebszustand möglich, bei dem das gesamte Abgas aus dem Zufluss in den (nicht geschlossenen) ersten Abfluss strömt, der beispielsweise mit der Abgasanlage verbunden sein kann, so dass das keine Abgasrückführung, jedoch auch keine Umgehung eines Abgaskühlers erfolgt. Die gesamte, in dem Abgas enthaltene Wärmeenergie kann somit, beispielsweise zur Erwärmung des Fahrzeuginnenraums, genutzt werden.In this way, in the case that both sets of valves are closed, for example, an operating state is possible in which the entire exhaust gas flows from the inflow into the (not closed) first outflow, which can be connected to the exhaust system, for example, so that no exhaust gas recirculation, However, there is no bypass of an exhaust gas cooler. The entire heat energy contained in the exhaust gas can thus be used, for example for heating the vehicle interior.
In einem zweiten Betriebszustand ist weiterhin eine vollständige Nutzung der Wärmeenergie möglich, durch eine steuerbare, das heißt zwischen 1 und 100 % einstellbare Öffnung des Ventils zu dem zweiten Abfluss kann jedoch eine gesteuerte Abgasrückführung erfolgen. In diesem Betriebszustand bleibt das zweite Ventil geschlossen, damit das Abgas weiterhin vollständig durch den Abgaskühler, und nicht dessen Bypass strömt, um die gesamte Wärmeenergie nutzen zu können. In diesem Fall strömt das entsprechend der gestalteten Öffnung nicht rückgeführte Abgas durch den vorangehend als ersten bezeichneten Auslass zur Abgasanlage.In a second operating state, a complete utilization of the heat energy is still possible, but controlled controllable exhaust gas recirculation can take place through a controllable, that is to say between 1 and 100% adjustable opening of the valve to the second outflow. In this operating state, the second valve remains closed, so that the exhaust gas continues to flow completely through the exhaust gas cooler, and not its bypass, in order to be able to use all the heat energy. In this case, the unreacted exhaust gas corresponding to the designed opening flows through the exhaust gas outlet previously referred to as first.
In einem dritten Betriebszustand ist das typischerweise zur Frischluftseite führende Ventil geschlossen, so dass keine Abgasrückführung erfolgt, jedoch der Bypass eines Abgaskühlers geöffnet, so dass dieser umgangen wird, und dem Abgas keine Wärmeenergie entzogen wird.In a third operating state, the valve typically leading to the fresh air side is closed, so that no exhaust gas recirculation takes place, but the bypass of an exhaust gas cooler is opened so that it is bypassed, and no heat energy is withdrawn from the exhaust gas.
In vorteilhafter Weise können sämtliche der genannten Betriebszustände mit einem einzigen Aktuator realisiert werden. Insofern stellt die Erfindung ein einziges Ventil mit einem Zufluss, zwei Abflüssen und einer weiteren Öffnung dar, die beispielsweise als Zufluss von einem Kühler-Bypass genutzt werden kann. In diesem Fall wäre das erfindungsgemäße Ventil stromabwärts des Kühlers und seines Bypasses angeordnet, so dass im Fall eines geschlossenen Ventils stromabwärts des Bypasses das Abgas den Strömungspfad durch den Abgaskühler wählt. Wenn das Ventil geöffnet ist, sind die Druckverhältnisse derart, dass das Abgas durch das geöffnete Ventil von dem Kühler-Bypass zuströmt. Der Abgaskühler stellt nämlich, verglichen mit dem Strömungspfad zur Abgasanlage, den größeren Strömungswiderstand dar.Advantageously, all of the mentioned operating states can be realized with a single actuator. In this respect, the invention represents a single valve with an inflow, two outlets and a further opening, which can be used for example as an inflow from a radiator bypass. In this case, the valve according to the invention would be arranged downstream of the radiator and its bypass, so that in the case of a closed valve downstream of the bypass, the exhaust gas selects the flow path through the exhaust gas cooler. When the valve is opened, the pressure conditions are such that the exhaust gas through the open valve of flows to the radiator bypass. The exhaust gas cooler is in fact, compared to the flow path to the exhaust system, the greater flow resistance.
Bevorzugte Weiterbildungen des erfindungsgemäßen Ventils sind in den weiteren Ansprüchen beschrieben.Preferred developments of the valve according to the invention are described in the further claims.
Eine besonders einfache Gestaltung des erfindungsgemäßen Ventils wird ermöglicht, wenn die Ventilsitze in entgegengesetzten Richtungen öffenbar sind, und die jeweiligen Ventile an entgegengesetzten Seiten federnd gelagert sind. Hierdurch ergibt sich in besonders einfacher Weise das oben beschriebene „Abstützen“ des jeweils geschlossenen Ventilelements in dem Fall, dass das andere Ventilelement geöffnet werden soll.A particularly simple design of the valve according to the invention is made possible when the valve seats can be opened in opposite directions, and the respective valves are resiliently mounted on opposite sides. This results in a particularly simple manner, the above-described "supporting" the respective closed valve element in the event that the other valve element is to be opened.
Für eine definierte Anordnung der Zu-, Abflüsse und der weiteren Öffnung bezüglich der dazwischen angeordneten Ventilelemente hat sich die Ausbildung jeweiliger Gasräume zwischen dem Zufluss und den Ventilsitzen sowie zwischen dem jeweiligen Ventilsitz und einem Abfluss und der weiteren Öffnung als günstig erwiesen.For a defined arrangement of the inflows, outflows and the further opening with respect to the valve elements arranged therebetween, the formation of respective gas spaces between the inflow and the valve seats and between the respective valve seat and a drain and the further opening has proven to be favorable.
Im Hinblick auf die Bauart des Ventils wird derzeit die Ausbildung zumindest eines Ventilelements als Ventilteller oder -klappe bevorzugt. Im Fall von Ventiltellern ist der Ventilschaft translatorisch bewegbar, und die Ventilteller weisen jeweils eine Öffnung auf, durch welche sich der Ventilschaft für die federnde Lagerung erstreckt. Im Fall von Ventilklappen wäre der gemeinsame Schaft typischerweise drehend oder schwenkend betätigbar.With regard to the design of the valve, the formation of at least one valve element as a valve plate or flap is currently preferred. In the case of valve plates, the valve stem is translationally movable, and the valve discs each have an opening through which extends the valve stem for the resilient mounting. In the case of valve flaps, the common shaft would typically be rotationally or pivotally operable.
Wenngleich das erfindungsgemäße Ventil allein einsetzbar ist, bildet ein Abgasrückführ(AGR)-System mit zumindest einem derartigen Ventil einen weiteren Gegenstand der Erfindung.Although the valve according to the invention can be used alone, an exhaust gas recirculation (EGR) system with at least one such valve forms a further subject of the invention.
In diesem Fall wird, wie bereits angedeutet, bevorzugt, dass der Zufluss mit der Abgasleitung eines Verbrennungsmotors verbunden ist, ein Abfluss mit der Abgasanlage, der zweite Abfluss mit der Frischluftseite des Motors für die Abgasrückführung, und die weitere Öffnung mit dem Auslass von einem Kühler-Bypass. Durch diese Gestaltung sind die oben genannten Betriebszustände in vorteilhafter Weise darstellbar.In this case, as already indicated, it is preferred that the inflow is connected to the exhaust pipe of an internal combustion engine, an outflow to the exhaust system, the second outflow to the fresh air side of the exhaust gas recirculation engine, and the further opening to the outlet from a radiator -Bypass. With this configuration, the above-mentioned operating conditions can be displayed in an advantageous manner.
