Description
Die Erfindung betrifft eine Abgasrückführventileinrichtung für einen Abgastrakt einer Verbrennungskraftmaschine nach dem Oberbegriff von Patentanspruch 1.The The invention relates to an exhaust gas recirculation valve device for one Exhaust tract of an internal combustion engine according to the preamble of claim 1.
Zudem betrifft sie einen Abgastrakt für eine Verbrennungskraftmaschine nach dem Oberbegriff von Patentanspruch 2 und eine Zuführeinrichtung für einen Abgastrakt nach dem Oberbegriff von Patentanspruch 4. Darüber hinaus betrifft die Erfindung eine Verbrennungskraftmaschine nach dem Oberbegriff von Patentanspruch 5.moreover it concerns an exhaust tract for an internal combustion engine according to the preamble of claim 2 and a feeder for one Exhaust tract according to the preamble of claim 4. In addition The invention relates to an internal combustion engine according to the preamble of claim 5.
Gemäß dem Stand der Technik sind bereits zweiflutige Abgasrückführventile bekannt. Sie kommen im Abgastrakt von Verbrennungskraftmaschinen, insbesondere bei direkt einspritzenden Motoren zum Einsatz, bei denen das Verfahren der Abgasrückführung zur Verminderung der NOx-Rohemissionen Anwendung findet. Nachteilig ist, dass sich bei diesen Abgasrückführventilen konstruktionsbedingt nicht immer eine absolut symmetrische Entnahme des zurückgeführten Abgases realisieren lässt. Zudem ist ein gezielter Transport von heißem Abgas zu einem Abgasnachbehandlungssystem in etwaiger Kombination mit einer gezielten Temperaturerhöhung des Abgases auf nur einer Flut nicht möglich. Es ist wünschenswert, gezielt heißes Abgas zu entsprechenden Abgasnachbehandlungssystemen zu leiten und die Abgastemperatur gegebenenfalls durch bestimmte Maßnahmen weiter zu erhöhen.According to the state The art already known twin-flow exhaust gas recirculation valves. they are coming in the exhaust tract of internal combustion engines, especially in direct Injection engines are used in which the process of Exhaust gas recirculation for Reduction of NOx raw emissions applies. adversely is that with these exhaust gas recirculation valves Due to the design, not always an absolutely symmetrical removal of the recirculated exhaust gas can be realized. In addition, a targeted transport of hot exhaust gas to an exhaust aftertreatment system in any combination with a targeted increase in temperature of the Exhaust gas is not possible on just one tide. It is desirable specifically hot To direct exhaust gas to corresponding exhaust aftertreatment systems and the exhaust gas temperature possibly by certain measures continue to increase.
Es ist daher Aufgabe der vorliegenden Erfindung, eine Abgasrückführventileinrichtung der eingangs genannten Art derart weiter zu entwickeln, dass die Abgastemperatur auch bei niedrigen Lasten erhöht und weiterhin Abgas genutzt werden kann, um durch Abgasrückführung die NOx-Rohemissionen zu reduzieren.It is therefore an object of the present invention, an exhaust gas recirculation valve device of the type mentioned in such a way that the Exhaust temperature increased even at low loads and continues to use exhaust gas can be to exhaust gas recirculation through the To reduce NOx raw emissions.
Vorteilhafte Ausgestaltungen mit zweckmäßigen und nicht-trivialen Weiterbildungen der Erfindung sind in den abhängigen Ansprüchen angegeben.advantageous Embodiments with appropriate and non-trivial developments of the invention are indicated in the dependent claims.
Diese Aufgaben werden zum einen durch eine Abgasrückführventilreinrichtung mit den Merkmalen des Patentanspruchs 1, durch einen Abgastrakt für eine Verbrennungskraftmaschine mit den Merkmalen des Patentanspruchs 2 und zum anderen durch eine Zuführeinrichtung für einen Abgastrakt mit den Merkmalen des Patentanspruchs 4 gelöst. Zur Erfindung gehört auch eine Verbrennungskraftmaschine mit den Merkmalen des Patentanspruchs 5.These Tasks are on the one hand by an exhaust gas recirculation valve device with the Characteristics of claim 1, by an exhaust tract for an internal combustion engine with the features of claim 2 and on the other by a feeding for one Exhaust tract solved with the features of claim 4. To the invention belongs also an internal combustion engine with the features of the claim 5th
Eine erfindungsgemäße Abgasrückführventileinrichtung mit zwei separat voneinander regelbaren Ventilen für ihre jeweilige Durchströmöffnung unterstützt eine Abgastemperaturerhöhung beispielsweise bei niedrigen Lasten während einer aktiven Dieselpartikelfilterregeneration bei Motoren, bei denen ein Verfahren der Abgasrückführung, insbesondere zur Reduzierung der NOx-Rohemissionen, zum Einsatz kommt.A Exhaust gas recirculation valve device according to the invention with two separately controllable valves for their respective Throughflow supports a Exhaust gas temperature increase for example, at low loads during active diesel particulate filter regeneration in engines where a method of exhaust gas recirculation, in particular for reduction of the raw NOx emissions, is used.
Die aktive Dieselpartikelfilterregeneration mithilfe einer motorexternen Kraftstoffeinspritzung (HC-Doser) oder einer motorinternen späten Nacheinspritzung erfordert zur Umsetzung des Kraftstoffs in einem Oxidationskatalysator hohe Abgastemperaturen. Bisherige Verfahren zur Abgastemperaturerhöhung betreffen beispielsweise die Lambda-Absenkung der Einlassdrossel, wobei Probleme mit der mechanischen Festigkeit und der Vereisung durch Kondensation von zurückgeführtem Abgas und anschließender Eisbildung an der Drosselklappe auftreten.The Active diesel particulate filter regeneration with the help of an external engine Fuel injection (HC-Doser) or an engine-internal late post-injection requires the conversion of the fuel in an oxidation catalyst high exhaust gas temperatures. Previous methods for exhaust gas temperature increase relate For example, the lambda reduction of the intake throttle, with problems with mechanical strength and icing by condensation of recirculated exhaust gas and subsequently Ice formation at the throttle occur.
Die Verwendung eines externen Brenners verursacht hohe zusätzliche Kosten und erfordert eine separate Luftzufuhr/Regelung.The Using an external burner causes high extra Costs and requires a separate air supply / regulation.
Bei einer Abgastemperaturerhöhung durch Lambda-Absenkung mit Hilfe eines Wastegates bei zweiflutigen Turbinen eines Abgasturboladers mit Wastegate auf einer Flut können gerade bei kleinen Lasten nicht ausreichend hohe Temperaturen realisiert werden, um eine oben erwähnte Umsetzung des Kraftstoffs zu realisieren.at an exhaust gas temperature increase by lambda lowering with the aid of a wastegate in double-flow Turbines of an exhaust gas turbocharger with wastegate on a high tide can straight at low loads not sufficiently high temperatures realized be to one mentioned above Implementation of the fuel to realize.
Diese Probleme werden durch den Einsatz einer erfindungsgemäßen Abgasrückführventileinrichtung für einen Abgastrakt mit separat voneinander regelbaren Ventilen für ihre Durchströmöffnungen gelöst. Durch Schließen einer Durchströmöffnung und damit einer dieser Durchströmöffnung zugeordneten Abgasrückführ-Flut und gleichzeitigem Öffnen eines Wastegates an einem zweiflutigen Abgasturbolader auf dieser Flut wird das heiße Abgas direkt am Turbolader vorbei über eine Abgasverrohrung zu einem Abgasnachbehandlungssystem geleitet. Verstärkt werden kann die Temperaturerhöhung des Abgases durch eine späte Nacheinspritzung in zumindest einem der Abgasverrohrung der geschlossenen Flut zugeordneten Zylinder. Es ist auch denkbar, dass im Gegensatz zu der beschriebenen motorinternen eine motorexterne Nacheinspritzung von Kraftstoff erfolgt. Hierzu wird über eine im Abgastrakt der Verbrennungskraftmaschine verbaute Zuführeinrichtung Kraftstoff eingespritzt, der aufgrund der hohen Abgastemperatur des direkt abgeleiteten Abgases im Oxidationskatalysator umgesetzt wird und eine große Wärmeenergie abgibt.These Problems are caused by the use of an exhaust gas recirculation valve device according to the invention for one Exhaust tract solved with separately controllable valves for their flow openings. By Shut down a flow opening and thus associated with one of these flow-through Exhaust gas recirculation Flood and simultaneously opening one Wastegates on a twin-flow turbocharger on this flood that's going to be hot Exhaust gas directly past the turbocharger over an exhaust piping too passed an exhaust aftertreatment system. It is possible to increase the temperature increase of the Exhaust gas through a late Post-injection in at least one of the exhaust pipe of the closed flood associated cylinder. It is also conceivable that unlike the internal engine described a post-engine external refraining of fuel. This is done via a in the exhaust system of the internal combustion engine built-in feeder Fuel injected due to high exhaust gas temperature the directly derived exhaust gas reacted in the oxidation catalyst will and a great heat energy emits.
Eine zweite Abgasrückführungs-Flut, die der geöffneten Durchströmöffnung der Abgasrückführventileinrichtung zugeordnet ist, kann weiterhin zur Rückführung des Abgasgases in den Ansaugtrakt einer Verbrennungskraftmaschine zur Einstellung eines bestimmten NOx-Niveaus verwendet werden. Zusätzlicher Vorteil ist hierbei, dass das Abgas auf dieser Flut deutlich kälter ist, da keine Nacheinspritzung in einen korrespondieren Zylinder stattfindet und somit weniger Energie an eine Turbine des Abgasturboladers abgegeben werden kann.A second exhaust gas recirculation flow, which is associated with the open flow-through opening of the exhaust gas recirculation valve device, can furthermore be used to return the exhaust gas to the intake tract of an internal combustion engine for adjusting specific NOx levels. An additional advantage here is that the exhaust gas is significantly colder on this flood, since no post-injection takes place in a corresponding cylinder and thus less energy can be delivered to a turbine of the exhaust gas turbocharger.
Es ergibt sich somit eine Abgastemperaturerhöhung um bis zu 100°C. Des Weiteren können zusätzliche Bauteile wie z. B. Einlassdrossel, Brenner, o. Ä. entfallen. Darüber hinaus ist eine Dieselpartikelfilterregeneration bei kleinen Lasten möglich. Es ist dabei durchaus denkbar, eine erfindungsgemäße Abgasrückführventileinrichtung auch bei weiteren anderen Aufgaben einzusetzen, bei denen eine Erhöhung der Abgastemperatur erforderlich ist, so z. B. die Entstickung eines DeNOx-Katalysators.It thus results in an exhaust gas temperature increase by up to 100 ° C. Furthermore can extra Components such. B. intake throttle, burner, o. Ä. omitted. Furthermore is a diesel particulate filter regeneration possible for small loads. It It is quite conceivable, an exhaust gas recirculation valve device according to the invention also at other tasks where there is an increase in the Exhaust gas temperature is required, such. B. the denitrification of a DeNOx catalyst.
Eine Verbrennungskraftmaschine mit einer derartigen Abgasrückführventileinrichtung kann dadurch emissions- und verbrauchsarm betrieben und aufgrund des Wegfalls zusätzlicher Bauteile kostengünstig produziert und montiert werden.A Internal combustion engine with such exhaust gas recirculation valve device can thus be operated with low emissions and low consumption and due to the elimination of additional Components cost-effective produced and assembled.
