Abstract
Description
Die Erfindung betrifft ein Verfahren zur Regeneration eines von einem Abgas durchströmten Partikelfilters eines Kraftfahrzeugs sowie ein Kraftfahrzeug mit einem Verbrennungsmotor, einem in einer Abgasleitung des Verbrennungsmotors angeordneten Partikelfilter und einem Kohlenwasserstoffreformer gemäß dem Oberbegriff der Patentansprüche 1 bzw. 13.The The invention relates to a method for the regeneration of one of Exhaust gas flowed through Particle filter of a motor vehicle and a motor vehicle with an internal combustion engine, one in an exhaust pipe of the internal combustion engine arranged particulate filter and a hydrocarbon reformer according to the generic term of the claims 1 or 13.
Es ist zu erwarten, dass die zukünftige Abgasgesetzgebung für Kraftfahrzeuge zumindest in der Europäischen Gemeinschaft, den USA und Japan im Hinblick auf die Partikelemission immer mehr verschärft werden wird. Zur Erfüllung weiter herabgesetzter Emissionsgrenzwerte für Partikel wird es daher erforderlich werden, das Abgas einer zusätzlichen Nachbehandlung zu unterziehen.It is to be expected that the future Emission legislation for Motor vehicles at least in the European Community, the USA and Japan are getting more and more severe in terms of particle emissions becomes. To fulfillment It is therefore necessary to further reduce emission limit values for particles be the exhaust of an additional To undergo post-treatment.
Zur Reduzierung des Ausstoßes von Dieselruß und anderen bei der Verbrennung eines Kraftstoffs im Verbrennungsmotor eines Kraftfahrzeugs entstehenden partikelförmigen Abgasbestandteilen ist es bereits seit langem bekannt, das Abgas durch einen in der Abgasleitung angeordneten Partikelfilter hindurchzuleiten. Insbesondere dann, wenn das Fahrzeug über längere Zeit im Schwachlastbereich betrieben wird, muss dieser Partikelfilter von Zeit zu Zeit regeneriert werden, wobei die vom Filter zurückgehaltenen Partikel von den Filteroberflächen entfernt werden, um eine einwandfreie Funktion des Partikelfilters über seine weitere Laufzeit zu gewährleisten. Zur Regeneration des Partikelfilters ist es erforderlich, den Filter selbst und/oder den durch den Filter hindurchtretenden Abgasstrom aufzuheizen, um die vom Filter zurückgehaltenen Partikel zu verbrennen und dabei in gasförmige Reaktionsprodukte umzuwandeln.to Reduction of emissions of diesel soot and others when burning a fuel in the internal combustion engine a motor vehicle resulting particulate exhaust gas components It has long been known the exhaust through one in the exhaust pipe pass through arranged particulate filter. In particular, then when the vehicle over longer Time is operated in the low load range, this particulate filter be regenerated from time to time, with those retained by the filter Particles from the filter surfaces be removed to ensure proper functioning of the particulate filter over its to ensure a longer term. To regenerate the particulate filter, it is necessary to filter itself and / or the exhaust gas stream passing through the filter to heat up to burn the particles retained by the filter and in gaseous form To convert reaction products.
Bisher bekannte Verfahren sehen dabei entweder eine langsame passive Regeneration des Partikelfilters mit NO2 durch den CRT-Effekt bei Temperaturen ab 250°C oder eine schnelle aktive thermische Regeneration durch Reaktion des Kohlenstoffrußes mit Sauerstoff ab einer Temperatur von 550°C vor, wobei sich das zuletzt genannte Verfahren auch zur Notregeneration des Filters eignet.Previously known methods provide either a slow passive regeneration of the particulate filter with NO 2 by the CRT effect at temperatures above 250 ° C or a rapid active thermal regeneration by reaction of carbon soot with oxygen from a temperature of 550 ° C, wherein the the latter method is also suitable for emergency regeneration of the filter.
Da die für diese Verfahren erforderlichen Mindesttemperaturen in der Abgasleitung eines Verbrennungsmotors jedoch vor allem im Stadtverkehr selten oder nie erreicht werden, muss eine zusätzliche Aufheizung des Filters oder des Abgases erfolgen. Diese zusätzliche Aufheizung wird bisher gewöhnlich durch einen Eingriff ins Motormanagement herbeigeführt. Dabei unterscheidet man einerseits zwischen rein motorseitigen Heizmaßnahmen in Form eines Eingriffs in den Verbrennungsablauf sowie andererseits katalytischen Heizmaßnahmen, zum Beispiel in Form einer späten Nacheinspritzung, bei der die an der Oberfläche eines Oxidationskatalysators erzeugte Wärme zur Aufheizung des Abgasstroms und zur Regeneration des nachgeschalteten Partikelfilters ausgenutzt wird.There the for These procedures required minimum temperatures in the exhaust pipe an internal combustion engine, however, especially in city traffic rare or never be reached, needs an additional heating of the filter or of the exhaust gas. This additional heating is so far usually caused by an intervention in the engine management. there On the one hand, a distinction is made between purely engine-side heating measures in the form of an intervention in the combustion process and on the other hand catalytic heating measures, for Example in the form of a late Post-injection, in which at the surface of an oxidation catalyst generated heat for heating the exhaust gas stream and for regeneration of the downstream particulate filter is exploited.
Bei beiden Verfahren ist jedoch von Nachteil, dass sie einen erhöhten Kraftstoffverbrauch infolge eines ungünstigeren Motorbetriebs und eine mögliche Ölverdünnung durch Kraftstoffeintrag zur Folge haben.at however, both methods have the disadvantage of being more fuel efficient as a result of a less favorable Engine operation and a possible oil thinning by Fuel entry result.
Ausgehend hiervon liegt der Erfindung die Aufgabe zugrunde, ein Verfahren und ein Kraftfahrzeug der eingangs genannten Art dahingehend zu verbessern, dass eine Regeneration des Partikelfilters ohne Eingriff in das Motormanagement und ohne die damit verbundenen ungünstigen Betriebszustände des Motors ermöglicht wird.outgoing This is the object of the invention, a method and to improve a motor vehicle of the type mentioned in the introduction, that a regeneration of the particulate filter without intervention in the Engine management and without the associated unfavorable operating conditions of the engine allows becomes.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass dem Abgas vor seinem Eintritt in den Partikelfilter aus einem Kohlenwasserstoffreformer ein oxidationsfähiges Reformatgas zugeführt wird, um durch eine katalytische Oxidation des Reformatgases die zu regenerierende Rußschicht an der Oberfläche des Partikelfilters direkt oder indirekt durch Aufheizung des Abgases auf die für eine aktive thermische Regeneration erforderlichen Temperaturen zu erhitzen.These Task is inventively characterized solved, that the exhaust gas before it enters the particulate filter from a Hydrocarbon reformer is fed to an oxidizable reformate gas, by a catalytic oxidation of the reformate gas to be regenerated soot on the surface the particulate filter directly or indirectly by heating the exhaust gas on the for an active thermal regeneration required temperatures to heat.
Der verhältnismäßig hohe Brennwert des Reformatgases und die niedrigen Zündtemperaturen des im Reformatgas enthaltenen Wasserstoffs H2 und Kohlenmonoxids CO führen bereits bei niedrigen Temperaturen zu einem sehr schnellen Einsetzen der katalytischen oxidativen Umsetzung des Reformatgases und damit zu einer schnellen Aufheizung des Partikelfilters bzw. des diesen durchströmenden Abgases und somit zu einer schnellen Einleitung der Regeneration, bei der die im Partikelfilter abgeschiedenen Partikel oxidiert und in gasförmige Reaktionsprodukte umgesetzt werden.The relatively high calorific value of the reformate gas and the low ignition temperatures of the hydrogen contained in the reformate H 2 and carbon monoxide CO already at low temperatures to a very rapid onset of catalytic oxidative conversion of the reformate gas and thus to rapid heating of the particulate filter or the exhaust gas flowing through it and thus to a rapid initiation of the regeneration, in which the particles deposited in the particle filter are oxidized and converted into gaseous reaction products.
Da die Zufuhr von Reformatgas von der jeweiligen Betriebsweise des Verbrennungsmotors unabhängig ist, lässt sich zudem die Regeneration des Partikelfilters vollständig vom Motorbetrieb entkoppeln, wodurch ein Eingriff in das Motormanagement zur Filterregeneration vermieden und dieses dadurch vereinfacht wird. Außerdem kann der Kraftstoffverbrauch insgesamt verringert werden.There the supply of reformate gas from the respective operation of the Internal combustion engine independently is, lets In addition, the regeneration of the particulate filter completely from Decouple engine operation, thereby interfering with engine management Filter regeneration avoided and this is simplified. Furthermore the fuel consumption can be reduced overall.
Die katalytische Oxidation des Reformatgases kann in einem vor dem Partikelfilter in der Abgasleitung des Verbrennungsmotors angeordneten Oxidationskatalysator oder vorzugsweise innerhalb des katalytisch beschichteten Partikelfilters selbst erfolgen, um eine hohe thermische Belastung des Oxidationskatalysators zu vermeiden. Im zuerst genannten Fall wird das Reformatgas dem Abgas zweckmäßig vor dessen Eintritt in den in der Abgasleitung angeordneten Oxidationskatalysator zugeführt, um es innerhalb des Oxidationskatalysators zu oxidieren und so den Abgasstrom auf die für eine aktive thermische Regeneration erforderlichen Temperaturen von mehr als 550°C zu erhitzen, bei denen die im Partikelfilter abgeschiedenen Rußpartikel unter Bildung gasförmiger Reaktionsprodukte mit dem Restsauerstoff im aufgeheizten Abgas reagieren.The catalytic oxidation of the reformate gas can be arranged in an Oxi in front of the particulate filter in the exhaust pipe of the internal combustion engine dationskatalysator or preferably within the catalytically coated particulate filter itself to avoid a high thermal load of the oxidation catalyst. In the former case, the reformate gas is expediently supplied to the exhaust gas prior to its entry into the oxidation catalyst disposed in the exhaust conduit to oxidize it within the oxidation catalyst to heat the exhaust stream to the temperatures required for active thermal regeneration greater than 550 ° C in which the soot particles deposited in the particle filter react with the residual oxygen in the heated exhaust gas to form gaseous reaction products.
Im zuletzt genannten Fall wird das Reformatgas dem Abgas zweckmäßig nach dessen Austritt aus dem Oxidationskatalysator zugeführt und vorzugsweise kurz vor dem Partikelfilter in die Abgasleitung eingespeist, um Wärmeverluste zu minimieren.in the latter case, the reformate is the exhaust gas appropriately after whose exit is fed from the oxidation catalyst and preferably fed into the exhaust pipe just before the particulate filter, for heat loss to minimize.
Wenn, wie bei manchen Kraftfahrzeugen, in der Abgasleitung zwei Oxidationskatalysatoren vorhanden sind, von denen einer in der Nähe des Verbrennungsmotors angeordnet ist, um eine hohe Abgaseintrittstemperatur sicherzustellen, wird das Reformatgas dem Abgas zweckmäßig nach seinem Austritt aus dem ersten und vor seinem Eintritt in den zweiten Oxidationskatalysator zugeführt.If, As with some motor vehicles, in the exhaust pipe two oxidation catalysts are present, one of which is arranged in the vicinity of the internal combustion engine is to ensure a high exhaust gas inlet temperature is the reformate after the exhaust gas appropriately his resignation from the first and before his entry into the second Oxidation catalyst supplied.
Der Kohlenwasserstoffreformer, aus dem das zur Regeneration des Partikelfilters verwendete Reformatgas stammt, kann eine unabhängige Komponente sein, die nur das zur Regeneration des Partikelfilters und ggf. das beim Start des Verbrennungsmotors zur Aufheizung des Oxidationskatalysators erforderliche Reformatgas erzeugt und daher ohne eine nachgeschaltete Gasreinigungseinheit auskommt. Vorzugsweise ist er jedoch Teil eines Brennstoffzellensystems des Kraftfahrzeugs, das die zum Betrieb verschiedener Verbraucher des Fahrzeugs benötigte elektrische Energie erzeugt.Of the Hydrocarbon reformer, from which the regeneration of the particulate filter used reformate gas may be an independent component, the only for the regeneration of the particulate filter and possibly the start the internal combustion engine required for heating the oxidation catalyst Reformatgas generated and therefore without a downstream gas cleaning unit gets along. Preferably, however, it is part of a fuel cell system of the motor vehicle used to operate various consumers needed the vehicle generates electrical energy.
In beiden Fällen wird im Reformer vorzugsweise der zum Betrieb des Verbrennungsmotors eingesetzte Kraftstoff umgesetzt. Während das dabei erzeugte Reformatgas aus einer unabhängigen Komponente direkt in die Abgasleitung zugeführt wird, wird es aus einem Brennstoffzellensystem vorzugsweise zwischen dem Reformer und einem Brennstoffzellenstapel abgezweigt, wobei die Entnahme vor oder hinter einer Gasreinigungseinheit erfolgen kann, sofern das Brennstoffzellensystem mit einer solchen Einheit ausgestattet ist. Alternativ ist es jedoch auch möglich, abgereichertes Reformatgas in Form von Anodenrestgas hinter dem Brennstoffzellenstapel abzuzweigen und in die Abgasleitung zuzuführen.In both cases is in the reformer, preferably for operating the internal combustion engine implemented fuel implemented. While the generated reformate gas from an independent Component is fed directly into the exhaust pipe, it will be out of one Fuel cell system preferably between the reformer and a Fuel cell stack diverted, the removal before or behind a gas cleaning unit can be made, provided the fuel cell system equipped with such a unit. Alternatively, it is also possible, depleted reformate gas in the form of anode residual gas behind the Branch fuel cell stack and feed into the exhaust pipe.
