Abstract
Description
Stand der TechnikState of the art
Bei Kraftwagen mit Verbrennungskraftmaschinen muss aufgrund der in den nächsten Jahren anstehenden verschärften Abgasgesetzgebung unter anderem der Schadstoff NOx im Abgas reduziert werden. Ein hierzu angewendetes, wirksames Verfahren ist das SCR-Verfahren (selektive katalytische Reduktion), bei dem der Schadstoff NOx unter Zuhilfenahme von flüssigem Reduktionsmittel zu N2 und H2O reduziert wird. Das Reduktionsmittel wird in der Regel in einer Leitung vom Vorratstank zum Dosiermodul gefördert, an dem es in den Abgastrakt der Verbrennungskraftmaschine in der Regel eingesprüht wird. Die heute üblicherweise eingesetzten flüssigen Reduktionsmittel gefrieren je nach zugesetztem Antifrostmittel bei Temperaturen zwischen –11°C und –40°C.In the case of motor vehicles with internal combustion engines, it is necessary, inter alia, to reduce the pollutant NO x in the exhaust gas on account of the more stringent exhaust gas legislation pending in the next few years. An effective method used for this purpose is the SCR process (selective catalytic reduction), in which the pollutant NO x is reduced to N 2 and H 2 O with the aid of liquid reducing agent. The reducing agent is usually conveyed in a line from the storage tank to the metering module, where it is usually sprayed into the exhaust gas tract of the internal combustion engine. Depending on the antifreeze added, the liquid reducing agents commonly used today freeze at temperatures between -11 ° C and -40 ° C.
Das Gefrieren des Reduktionsmittels erfolgt in der Regel von der Außenseite des Tanks, was bedeutet, dass die im Topf bevorratete Menge von flüssigem Reduktionsmittel zum Schluss gefriert. Damit einher geht die Gefahr, dass die expandierende Menge über einen Zulauf in das Innere des Topfs gedrückt wird, so dass die Möglichkeit besteht, dass der Flüssigkeitspegel innerhalb des Topfes so weit ansteigt, dass dieser erheblich über dem normalen Flüssigkeitsspiegel liegt und gegebenenfalls auf die Deckelunterseite drückt.The freezing of the reducing agent is usually carried out from the outside of the tank, which means that the amount of liquid reducing agent stored in the pot freezes at the end. This is accompanied by the risk that the expanding amount is forced through an inlet into the interior of the pot, so that there is the possibility that the liquid level within the pot rises so much that it is significantly above the normal liquid level and possibly on the underside of the lid suppressed.
Offenbarung der ErfindungDisclosure of the invention
Erfindungsgemäß wird vorgeschlagen, in einem Vorratstank zur Aufnahme eines insbesondere gefrierfähigen Reduktionsmittels die Variantenvielfalt dadurch zu reduzieren, dass der im Inneren des Vorratstanks ausgebildete, das Heizelement umschließende Topf aus einem rohrförmigen Einsatz gefertigt ist, dessen Wand zumindest in axiale Richtung verformbar ausgebildet ist. Insbesondere wird der rohrförmig ausgebildete Einsatz im Vorratstank aus Kunststoffmaterial gefertigt, so z. B. aus Kunststoffwellrohr. Die Wandprofilierung kann derart ausgebildet sein, dass diese wellblechförmig profiliert ist, wobei sich die z. B. in Wellblechform ausgebildete Profilierung durchgängig über die gesamte axiale Länge des rohrförmig ausgebildeten Einsatzes aus Kunststoffmaterial erstreckt. Alternativ dazu kann in axiale Richtung des rohrförmig ausgebildeten Einsatzes die Wandprofilierung in diskontinuierlichen Abschnitten ausgebildet sein, so z. B. an der oberen und an der unteren Stirnseite ausgebildet sein, wobei sich zwischen den Stirnseiten ein Abschnitt aus unverformbarem Wandmaterial befindet.According to the invention, in a storage tank for receiving a particular freezable reducing agent to reduce the variety in that the inside of the storage tank formed, the heating element enclosing pot is made of a tubular insert whose wall is formed deformable at least in the axial direction. In particular, the tubular insert is made in the storage tank made of plastic material, such. B. plastic corrugated pipe. The wall profiling can be designed such that it is profiled corrugated sheet, wherein the z. B. formed in corrugated sheet profiling continuously extends over the entire axial length of the tubular insert made of plastic material. Alternatively, in the axial direction of the tubular insert formed the wall profiling may be formed in discontinuous sections, such. B. be formed on the upper and on the lower end face, wherein there is a portion of undeformable wall material between the end faces.
Durch die erfindungsgemäß vorgeschlagene Lösung kann den unterschiedlichen Einbauverhältnissen der Vorratstanks für SCR-Dosiersysteme dahingehend Rechnung getragen werden, dass nunmehr eine Einheitslänge eines rohrförmig ausgebildeten Einsatzes in Vorratstanks eingebaut werden kann, die in unterschiedlicher Höhe ausgebildet sind. Damit kann die Eisdruckfestigkeit eines derartigen Vorratstanks, der ein gefrierfähiges Reduktionsmittel bevorratet, erheblich erhöht werden. Insbesondere kann durch die erfindungsgemäß vorgeschlagene Lösung das zur Zeit praktizierte gerichtete Einfrieren des Reduktionsmittels umgangen werden, da das gerichtete Einfrieren nicht bei allen Tankgeometrien realisiert werden kann.By inventively proposed solution, the different installation conditions of the storage tanks for SCR metering be taken into account that now a unit length of a tubular insert can be installed in storage tanks, which are formed in different heights. Thus, the ice crushing strength of such a storage tank storing a freezing reductant can be significantly increased. In particular, by the solution proposed by the present invention, the directional freezing of the reducing agent practiced at the present time can be circumvented, since directional freezing can not be realized in all tank geometries.
Der erfindungsgemäß vorgeschlagenen Lösung folgend, ist der rohrförmig ausgebildete Einsatz in einer axialen Länge ausgebildet und weist eine axiale Flexibilität auf, welche die unterschiedlichen Tankhöhen von Vorratstanks überspannen kann. Insbesondere lässt sich in fertigungstechnisch besonders einfacher Weise der rohrförmige Einsatz in einer im Tankboden des Vorratstanks ausgebildeten muldenförmigen Vertiefung an einem Ende fixieren. Das diesem einen Ende gegenüberliegende andere Ende des rohrförmigen Einsatzes kann z. B. im Bereich des Deckels des Vorratstanks an einer Zentrierung fixiert sein. Ein Ausknicken des rohrförmigen Einsatzes, der insbesondere aus Kunststoffmaterial gefertigt ist, kann aufgrund dieser beidseitigen Lagerung des rohrförmigen Einsatzes verhindert werden. Im Gegensatz zu bei Lösungen gemäß des Standes der Technik üblicherweise eingesetzten ringförmigen großflächigen Gummidichtungen, welche den Inhalt des Topfes des Vorratstanks gegen das diesen umschließende Eis abschirmen, wird bei der erfindungsgemäß vorgeschlagenen Lösung lediglich ein Gummidichtring benötigt, wohingegen die Abdichtfunktion durch ein stirnseitiges Ende des rohrförmigen Einsatzes gebildet ist.Following the proposed solution according to the invention, the tubular insert is formed in an axial length and has an axial flexibility, which can span the different tank heights of storage tanks. In particular, the tubular insert can be fixed at one end in a trough-shaped recess formed in the tank bottom of the storage tank in a particularly simple manner in terms of production technology. The other one opposite this one end End of the tubular insert can, for. B. be fixed to a centering in the region of the lid of the storage tank. A buckling of the tubular insert, which is made in particular of plastic material, can be prevented due to this two-sided storage of the tubular insert. In contrast to in solutions according to the prior art commonly used annular large-area rubber seals which shield the contents of the pot of the storage tank against the surrounding this ice, in the proposed solution according to the invention, only a rubber sealing ring is needed, whereas the sealing function by a front end of the tubular Insert is formed.
Der rohrförmige Einsatz, insbesondere ausgebildet als ein profiliertes Wellrohr, hat sowohl im Bereich seines oberen Endes als auch im Bereich seines unteren Endes radiale Zufluss- bzw. Abflussöffnungen. Bevorzugt erfolgt die Befüllung des durch den rohrförmigen Einsatz gebildeten Topfes über die untenliegenden Öffnungen, die sich im eingebauten Zustand des rohrförmigen Einsatzes oberhalb der muldenförmigen Vertiefung im Tankboden des Vorratstanks befinden. Ist die Flüssigkeitsoberfläche im Vorratstank – außerhalb des rohrförmigen Einsatzes – gefroren, so entweicht Expansionsvolumen über die Zulauföffnung in das Innere des rohrförmigen Einsatzes und lässt den Flüssigkeitsstand dort bis zur Unterseite eines den Vorratstank verschließenden Deckels anwachsen. Die dadurch bei heutigen Ausführungsvarianten auftretenden Schäden am Deckel können vermieden werden, da der rohrförmige Einsatz im oberen Bereich Öffnungen aufweist, durch die sich das Expansionsvolumen wieder in den äußeren Tankraum des Vorratstanks ergießen kann, so dass eine Eisbildung direkt unterhalb des Deckels, welcher den Vorratstank verschließt, ausgeschlossen ist.The tubular insert, in particular designed as a profiled corrugated tube, has radial inflow or outflow openings both in the region of its upper end and in the region of its lower end. Preferably, the filling of the pot formed by the tubular insert via the underlying openings, which are in the installed state of the tubular insert above the trough-shaped depression in the tank bottom of the storage tank. If the liquid surface in the storage tank - outside of the tubular insert - frozen, as expansion volume escapes through the inlet opening into the interior of the tubular insert and allows the liquid level there to grow to the bottom of a cover closing the storage tank. The resulting damage to the cover in today's variants can be avoided, since the tubular insert has openings in the upper region, through which the expansion volume can pour back into the outer tank space of the storage tank, so that an ice formation directly below the lid, which the storage tank closes, is excluded.
Durch die erfindungsgemäß vorgeschlagene Lösung kann eine Schädigung von Einbauten bzw. Komponenten innerhalb des Vorratstanks vermieden werden. Dies ist insbesondere dadurch sichergestellt, dass sich die an der oberen Stirnseite oberhalb des Eispegels im Vorratstank befindlichen Öffnungen oberhalb des Eispegels des in Eisform innerhalb des Vorratstanks vorliegenden Reduktionsmittels befinden.By inventively proposed solution damage to internals or components can be avoided within the storage tank. This is ensured in particular by the fact that the openings located above the ice level in the storage tank at the upper end face are above the ice level of the reducing agent present in ice form within the storage tank.
