Description
Stand der TechnikState of the art
Das Reduktionsmittel, das im Wege des SCR-Verfahrens eingesetzt wird (SCR = selective catalytic reduction), gefriert je nach zugesetztem Antifrostmittel zwischen –11°C und –40°C. Da auch bei tiefen Temperaturen die Schadstoffe der Verbrennungskraftmaschine zu reduzieren sind, ist das Reduktionsmittel gegebenenfalls aufzutauen. Dazu befindet sich innerhalb des Reduktionsmitteltanks eine Heizung, die in der Regel elektrisch betrieben wird. Bei Personenkraftwagen hat sich im Gegensatz zu Nutzfahrzeuganwendungen eine elektrische Heizung durchgesetzt, während bei Nutzfahrzeuganwendungen die Heizung des Tanks über das Kühlwasser erfolgt.The reducing agent used in the SCR process (SCR = Selective Catalytic Reduction) freezes between -11 ° C and -40 ° C, depending on the antifreeze added. Since the pollutants of the internal combustion engine are to be reduced even at low temperatures, the reducing agent may need to be thawed. For this purpose, within the reducing agent tank is a heater, which is usually operated electrically. In passenger cars, in contrast to commercial vehicle applications, an electric heater has prevailed, while in commercial vehicle applications, the heating of the tank via the cooling water takes place.
Die elektrische Beheizung des Tanks einer Abgasnachbehandlungsanlage unter Verwendung von wässriger Harnstofflösung als Reduktionsmittel, erfordert ein effizientes Heiz- bzw. Auftaukonzept. Dies ist umso wichtiger, da von der Bordelektrik nur eine begrenzte elektrische Leistung zur Verfügung gestellt werden kann. Die gesetzlichen Bestimmungen erfordern ein rasches Auftauen einer begrenzten Reduktionsmittelmenge. Eine elektrische Heizung wird innerhalb des Tanks in ein Teilbehälter positioniert und ist in der Regel von einem Schwapp- oder Schwalltopf umgeben. Die Wände dieses Teilbehälters, der in der Regel aus Kunststoff gefertigt ist, stellen eine thermische Isolierung des Volumens, welches im Teilbehälter bevorratet ist, zur außen gegebenenfalls gefrorenen Flüssigkeit des Vorratstanks dar. Da diese Lösung überdies die Konvektion des über die Heizung aufgetauten Reduktionsmittels auf den Inhalt des Teilbehälters beschränkt, wird dieser weit vor dem Inhalt des Vorratstanks auftauen. Beim Gefrieren dehnt sich das Reduktionsmittel um ca. 10 Vol.-% aus. Diese Volumenausdehnung darf das Tanksystem nicht schädigen, d. h. das System ist so zu konfigurieren, dass es dem sich aufbauenden Eisdruck widersteht. Hinsichtlich des Tanks ist dieser so zu dimensionieren, dass ein Ausdehnungsvolumen von bis zu 3 l aufgenommen werden kann. Nicht alle in Personenkraftwagen eingesetzten Tanks haben eine ideale Einbausituation hinsichtlich der für die Eisdruckfähigkeit optimierten Form des Vorratstanks, manche Einbausituationen im Fahrzeug führen zu sehr ungünstigen Tankgeometrien. Unter ungünstiger Tankgeometrie ist im vorliegenden Zusammenhang eine Geometrie zu verstehen, bei der die im Tank bevorratete Flüssigkeit der kalten Umgebung eine sehr große Angriffsfläche bietet, wobei ein isolierender Luftraum relativ klein dimensioniert ist. Hinsichtlich der Anforderungen an die Eisdruckfähigkeit eines solchen Tanks ist der isolierende Luftraum zu kleinflächig. Der Vorratstank wird zunächst an der Außenwand gefrieren und es wird somit in der Mitte des Tanks eine flüssige Blase verbleiben, die beim Durchfrieren schließlich aufgrund ihrer Expansion zu einer Zerstörung des Tanksystems führen kann.The electrical heating of the tank of an exhaust aftertreatment system using aqueous urea solution as a reducing agent, requires an efficient heating or thawing concept. This is all the more important because of the on-board electrical system only a limited electrical power can be provided. The legal provisions require a rapid thawing of a limited amount of reducing agent. An electric heater is positioned within the tank in a sub-tank and is usually surrounded by a slosh or swirl pot. The walls of this sub-container, which is usually made of plastic, provide a thermal insulation of the volume, which is stored in the sub-container, to the outside optionally frozen liquid of the storage tank. Since this solution, moreover, the convection of thawed over the heating reducing agent on the Limited content of the sub-container, this will thaw far before the contents of the storage tank. Upon freezing, the reducing agent expands by about 10% by volume. This volume expansion must not damage the tank system, i. H. The system should be configured to withstand the build-up of ice pressure. With regard to the tank, this should be dimensioned so that an expansion volume of up to 3 l can be accommodated. Not all tanks used in passenger cars have an ideal installation situation with regard to the form of the storage tank, which is optimized for ice compressibility, and some installation situations in the vehicle lead to very unfavorable tank geometries. Unfavorable tank geometry in the present context is to be understood as meaning a geometry in which the liquid stored in the tank offers a very large attack surface to the cold environment, an insulating air space being dimensioned relatively small. With regard to the requirements of the Eisdruckfähigkeit such a tank, the insulating air space is too small. The storage tank will first freeze on the outer wall and it will thus remain in the middle of the tank, a liquid bubble, which can eventually lead to destruction of the tank system during freezing due to their expansion.
Die Beeinflussung des Einfrierverhaltens des im Vorratstank bevorrateten Reduktionsmittels über eine zusätzliche Isolierung auf der Außenseite des Tanks stellt zwar eine wirksame Maßnahme dar, ist jedoch häufig aus Bauraumgründen nicht möglich.Although influencing the freezing behavior of the reducing agent stored in the storage tank via additional insulation on the outside of the tank is an effective measure, it is often not possible for space reasons.
Darstellung der ErfindungPresentation of the invention
Erfindungsgemäß wird vorgeschlagen, einen Vorratstank zur Aufnahme eines Betriebs-/Hilfsstoffes, insbesondere eines gefrierfähigen Reduktionsmittels wie Harnstoff oder eine Harnstoff-Wasser-Lösung an seiner Mantelfläche und/oder im Bodenbereich zu beheizen, wobei als Heizmedium eine bereits an der Verbrennungskraftmaschine im Fahrzeug vorgesehene Wärmequelle herangezogen wird. Bei dieser im Fahrzeug bereits vorgesehenen Wärmequelle handelt es sich insbesondere um die Verbrennungskraftmaschine selbst, so zum Beispiel um den von dieser erzeugten Abgasstrom, der ein erhöhtes Temperaturniveau aufweist bzw. das innerhalb der Verbrennungskraftmaschine zirkulierende Kühlmedium.According to the invention it is proposed to heat a storage tank for receiving an operating / auxiliary substance, in particular a freezable reducing agent such as urea or a urea-water solution on its lateral surface and / or in the bottom region, wherein as a heating medium already provided on the internal combustion engine in the vehicle heat source is used. This heat source, which is already provided in the vehicle, is, in particular, the internal combustion engine itself, for example the exhaust gas flow generated by it, which has an elevated temperature level or the cooling medium circulating within the internal combustion engine.
In einer vorteilhaften Ausführungsvariante der erfindungsgemäß vorgeschlagenen Lösung, ist eine Zuleitung, in welcher entweder ein Abgasstrom oder besser gesagt ein Teil des Kühlwassers zirkuliert, in Mäanderform innerhalb des Vorratstanks angeordnet oder in die Mantelfläche des Vorratstanks integriert. Da der Vorratstank im Allgemeinen als Kunststoffspritzgussbauteil gefertigt ist, können die das Heizmedium führenden Kanäle bereits bei der Herstellung des Vorratstanks bzw. von Tankwänden bzw. Tankboden in diesen integriert werden. Alternativ dazu besteht die Möglichkeit, die das Heizmedium führende Leitung in Mäanderform im Inneren des Vorratstanks zu befestigen. Zulauf und Rücklauf der das Heizmedium führenden Leitung können an einer Bypass-Leitung angeschlossen werden, mit der ein z. B. Teilabgasstrom aus dem Abgastrakt der Verbrennungskraftmaschine hinter dem Endschalldämpfer entnommen und vor dem Endschalldämpfer wieder zugeführt wird. Wird die das Heizmedium führende Leitung an der Bodenfläche bzw. der Mantelfläche des Vorratstanks oder in dessen Innenraum in Mäanderform verlegt, so ergibt sich eine hohe vom Heizmedium bestrichene Fläche, so dass gefrorenes Reduktionsmittel, welches im Inneren des Vorratstanks bevorratet wird, gegebenenfalls schnell von innen aufgetaut werden kann. Neben einer Bedeckung der Mantelfläche bzw. einer Integration der Heizelemente in die Mantelfläche oder in die Bodenfläche, besteht auch die Möglichkeit, in Weiterbildung der erfindungsgemäß vorgeschlagenen Lösung in Mäanderform vorgesehene Heizleitungen deckelseitig am Vorratstank aufzubringen oder in die Deckelgeometrie des Vorratstanks zu integrieren.In an advantageous embodiment variant of the solution proposed according to the invention, a supply line in which either an exhaust gas stream or rather a part of the cooling water circulates is arranged in meandering form within the storage tank or integrated into the jacket surface of the storage tank. Since the storage tank is generally made as a plastic injection molded component, the channels carrying the heating medium can already be integrated in the production of the storage tank or tank walls or tank bottom. Alternatively, it is possible to attach the heating medium leading line in meandering form inside the storage tank. Inlet and return of the heating medium leading line can be connected to a bypass line, with a z. B. Partial exhaust stream taken from the exhaust tract of the internal combustion engine behind the muffler and before the muffler is fed again. If the line leading to the heating medium is laid on the bottom surface or the lateral surface of the storage tank or in its interior in meandering form, then a high area of the heating medium results, so that frozen reducing agent, which is stored in the interior of the storage tank, if necessary quickly from the inside can be thawed. In addition to covering the lateral surface or an integration of the heating elements in the lateral surface or in the bottom surface, it is also possible, in further development of the proposed solution according to the invention provided in meandering form heating pipes cover side on the storage tank or to integrate into the lid geometry of the storage tank.
Die Nutzung einer bereits im Fahrzeug vorhandenen Wärmequelle erlaubt eine Systemvereinfachung, da auf die elektrische Heizung verzichtet werden kann, die zudem eine relativ hohe elektrische Verlustleistung erzeugt, die über die Motorleistung zu kompensieren ist. Des Weiteren ist bei einer elektrischen Heizung deren Heizwirkung auf das Innere des Schwapptopfes begrenzt, ferner stellt eine elektrische Heizung eine Restriktion hinsichtlich des Tankdesigns dar.The use of an already existing in the vehicle heat source allows a simpler system, since it can be dispensed with the electric heater, which also generates a relatively high electrical power loss, which is to be compensated by the engine power. Furthermore, in the case of an electric heater, its heating effect is limited to the interior of the sloshpot, furthermore an electric heater represents a restriction with regard to the tank design.
Bei der erfindungsgemäß vorgeschlagenen Lösung können potentielle Systemausfälle durch Ausfall des elektrischen Heizers komplett eliminiert werden. Des Weiteren trägt die erfindungsgemäß vorgeschlagene Lösung zur CO2-Reduzierung bei und begünstigt ein schnelles Auftauen, was gesetzlich vorgeschrieben ist. Des Weiteren wird in Bezug auf die Fahrzeugelektrik die Pin-Belegung an einem EDC-Steuergerät reduziert sowie die Endstufenzahl der DCU reduziert. Die Heizfläche, auf die das von der Verbrennungskraftmaschine erzeugte Heizmedium oder das in dieser zirkulierende Heizmedium wirkt, ist erheblich größer, verglichen mit der Fläche, die über eine elektrisch betriebene Beheizung erwärmt werden kann.In the proposed solution according to the invention potential system failures can be completely eliminated by failure of the electric heater. Furthermore, the proposed solution according to the invention contributes to CO 2 reduction and promotes rapid thawing, which is required by law. Furthermore, with regard to the vehicle electrics, the pin allocation to an EDC control unit is reduced and the final stage number of the DCU is reduced. The heating surface on which acts of the combustion medium produced by the internal combustion engine or the circulating in this heating medium, is considerably larger compared with the area which can be heated by an electrically operated heating.
