Description
Die Erfindung betrifft ein Verfahren zum Betreiben eines Wärmetauschersystems für ein Kraftfahrzeug oder ein Stationäraggregat mit den im Oberbegriff des Patentanspruches 1 genannten Merkmalen sowie eine dazugehörige Vorrichtung mit den im Oberbegriff des Patentanspruches 9 genannten Merkmalen.The invention relates to a method for operating a heat exchanger system for a motor vehicle or a stationary unit with the features mentioned in the preamble of claim 1 and an associated device with the features mentioned in the preamble of

Die
Nachteilig hierbei ist, dass während des Warmlaufens der Verbrennungskraftmaschine zusätzlich in einem Heizgerät Kraftstoff zur Erzeugung von zusätzlicher thermischer Energie einerseits zur schnellen Erwärmung des Katalysators und andererseits zur Erwärmung des kalten Kühlmediums benötigt wird. Außerdem wird zusätzlich Energie für die Betreibung eines Gebläses benötigt, um das aufgeheizte Gas dem Abgasstrom zuführen zu können. Neben dem zusätzlichen Heizgerät wird die Anlage durch aufwendige Regelungseinrichtungen verteuert.The disadvantage here is that during warming up of the internal combustion engine additionally fuel in a heater for generating additional thermal energy on the one hand for rapid heating of the catalyst and on the other hand for heating the cold cooling medium is needed. In addition, additional energy is needed for the operation of a blower in order to be able to supply the heated gas to the exhaust gas stream. In addition to the additional heater, the system is expensive by complex control devices.

Diese Aufgabe wird entsprechend dem Verfahren erfindungsgemäß durch die kennzeichnenden Merkmale des Patentanspruches 1 und entsprechend der Vorrichtung erfindungsgemäß durch die kennzeichnenden Merkmale des Patentanspruches 9 gelöst.This object is achieved according to the invention according to the invention by the characterizing features of claim 1 and according to the device by the characterizing features of
Erfindungsgemäß wird das dadurch erreicht, dass in der Warmlaufphase der Verbrennungskraftmaschine und bei einem Überschreiten einer maximal zulässigen Kühlmitteltemperatur das in dem Abgaswärmetauscher befindliche Kühlmedium durch einen Gasstrom (z. B. Luft) aus dem Abgaswärmetauscher verdrängt wird und das Gas in der Warmlaufphase bis zur Erreichung der Anspringtemperatur des Katalysators und bei einer Überschreitung der maximal zulässigen Kühlmitteltemperatur bis zum Erreichen einer zulässigen Kühlmitteltemperatur in dem Abgaswärmetauscher verweilt. Nach Erreichen der Anspringtemperatur des Katalysators bzw. nach einer Unterschreitung der maximal zulässigen Kühlmitteltemperatur wird der Abgaswärmetauscher entlüftet und danach wird dem Abgaswärmetauscher ein Kühlmedium zugeführt, das im indirekten Wärmetausch mit den Abgasen der Verbrennungskraftmaschine erhitzt wird.According to the invention this is achieved in that in the warm-up phase of the internal combustion engine and when exceeding a maximum coolant temperature, the cooling medium in the exhaust gas heat exchanger is displaced from the exhaust gas heat exchanger by a gas flow (eg air) and the gas in the warm-up phase until reaching the light-off temperature of the catalyst and when exceeding the maximum permissible coolant temperature until reaching an allowable coolant temperature dwells in the exhaust gas heat exchanger. After reaching the light-off temperature of the catalyst or after falling below the maximum permissible coolant temperature of the exhaust gas heat exchanger is vented and then the exhaust gas heat exchanger is supplied to a cooling medium which is heated in the indirect heat exchange with the exhaust gases of the internal combustion engine.
Die erfindungsgemäße Vorrichtung zeichnet sich dadurch aus, dass vor dem Abgaswärmetauscher die Zuführungsleitung für das Kühlmedium über ein erstes verstellbares Ventil mit einer Druckluftleitung und die Abführungsleitung für das Kühlmedium nach dem Abgaswärmetauscher über ein zweites verstellbares Ventil mit einer Luftleitung verbunden ist. Weiterhin ist der Abgaswärmetauscher derart ausgebildet, dass er im Querschnitt aus mehreren über- und nebeneinander angeordneten Wärmetauscherrohren besteht, deren Außenfläche als katalytisch wirksame Oberfläche ausgebildet ist und in den Katalysator integriert ist.The device according to the invention is characterized in that before the exhaust gas heat exchanger, the supply line for the cooling medium via a first adjustable valve with a compressed air line and the discharge line for the cooling medium is connected to the exhaust gas heat exchanger via a second adjustable valve with an air line. Furthermore, the exhaust gas heat exchanger is designed such that it consists in cross section of a plurality of over and juxtaposed heat exchanger tubes whose outer surface is formed as a catalytically active surface and is integrated into the catalyst.
Die Vorteile der erfindungsgemäßen Lösung bestehen darin, dass während der Warmlaufphase der Verbrennungskraftmaschine aus dem Kaltstart die thermische Masse im Abgaswärmetauscher reduziert wird. Anstelle des den Abgaswärmetauscher durchströmenden kalten Kühlmediums befindet sich in der Warmlaufphase in den Wärmeaustauscherrohren des Abgaswärmetauschers nur eine nichtbewegte Luftmenge. Dadurch wird erreicht, dass der katalytische Teil des Wärmetauschersystems schneller aufgeheizt wird und somit schneller seine Betriebstemperatur erreicht. Eine Wärmeabführung durch das Kühlmedium vom Katalysator in der Warmlaufphase der Verbrennungskraftmaschine erfolgt dabei nicht. Eine zusätzliche Heizung zur Erwärmung der Abgase in der Warmlaufphase der Verbrennungskraftmaschine, um dadurch schnell die Anspringtemperatur des Katalysators zu erreichen, ist nicht mehr erforderlich. Die Kosten für die Heizung und für den Kraftstoffverbrauch zum Betreiben der Heizung entfallen somit. Die erfindungsgemäße Lösung zeichnet sich durch einen unkomplizierten Aufbau aus, der auch mit einfachen bekannten Mitteln gut regelbar ist.The advantages of the solution according to the invention are that the thermal mass in the exhaust gas heat exchanger is reduced during the warm-up phase of the internal combustion engine from the cold start. Instead of the exhaust gas flowing through the exhaust gas heat exchanger cold cooling medium is in the warm-up phase in the heat exchanger tubes of the exhaust gas heat exchanger only a non-moving air flow. This ensures that the catalytic part of the heat exchanger system is heated faster and thus reaches its operating temperature faster. A heat dissipation through the cooling medium from the catalyst in the warm-up phase of the internal combustion engine is not carried out. An additional heater for heating the exhaust gases in the warm-up phase of the internal combustion engine, thereby quickly reaching the light-off temperature of the catalyst, is no longer necessary. The cost of heating and fuel consumption to operate the heating thus eliminated. The solution according to the invention is characterized by an uncomplicated structure, which can be well controlled even with simple known means.
Auch bei einer eventuellen Überhitzung des Kühlmediums (z. B. Wasser-/Glykolgemisch) wird durch die Unterbrechung des Kühlmitteldurchflusses durch die Wärmetauscherrohre des Abgaswärmetauschers, die Umleitung des Kühlmittelflusses über eine Bypassleitung und eine Gasaufschaltung im Abgaswärmetauscher eine schnelle und unkomplizierte Regelung des Wärmetauschersystems erreicht.Even with a possible overheating of the cooling medium (eg water / glycol mixture) is achieved by the interruption of the coolant flow through the heat exchanger tubes of the exhaust gas heat exchanger, the diversion of the coolant flow via a bypass line and a gas injection in the exhaust gas heat exchanger a quick and easy control of the heat exchanger system.
