Description
Die Erfindung betrifft ein Abgasnachbehandlungssystem für eine Brennkraftmaschine nach dem Oberbegriff des Anspruchs 1.The invention relates to an exhaust aftertreatment system for an internal combustion engine according to the preamble of claim 1.
Der Abgasnachbehandlung des Abgases einer Brennkraftmaschine eines Kraftfahrzeugs kommt durch sich zunehmend verschärfende Abgasvorschriften eine immer stärkere Bedeutung zu. Insbesondere müssen auch bei Otto-Brennkraftmaschinen Abgaspartikel aus dem Abgas entfernt werden.The exhaust aftertreatment of the exhaust gas of an internal combustion engine of a motor vehicle is becoming increasingly important due to increasingly stricter exhaust gas regulations. In particular, exhaust gas particles must also be removed from the exhaust gas in Otto internal combustion engines.
Aus der
Hiervon ausgehend liegt der hier vorliegenden Erfindung die Aufgabe zugrunde, ein neuartiges Abgasnachbehandlungssystem für eine Brennkraftmaschine mit verminderter Abgaspartikelemission zu schaffen.On this basis, the present invention has the object to provide a novel exhaust aftertreatment system for an internal combustion engine with reduced exhaust particulate emissions.
Diese Aufgabe wird durch ein Abgasnachbehandlungssystem gemäß Anspruch 1 gelöst. Erfindungsgemäß umfasst die Abgasnachbehandlungseinrichtung einen Abgaspartikelfilter und einen parallel zum Abgaspartikelfilter geschalteten Katalysator, wobei das Abgas der jeweiligen Zylindergruppe abhängig vom Betriebspunkt der Brennkraftmaschine entweder vollständig über den Abgaspartikelfilter oder teilweise über den Abgaspartikelfilter und teilweise über den Katalysator leitbar ist.This object is achieved by an exhaust aftertreatment system according to claim 1. According to the invention, the exhaust gas aftertreatment device comprises an exhaust gas particle filter and a catalytic converter connected in parallel with the exhaust gas particle filter, wherein the exhaust gas of the respective cylinder group can be conducted either completely via the exhaust gas particle filter or partly via the exhaust gas particle filter and partly via the catalyst, depending on the operating point of the internal combustion engine.
Mit der hier vorliegenden Erfindung wird ein Abgasnachbehandlungssystem für eine Brennkraftmaschine eines Kraftfahrzeugs vorgeschlagen, bei welchem abhängig vom Betriebspunkt der Brennkraftmaschine Abgas entweder vollständig über mindestens einen Abgaspartikelfilter oder teilweise über mindestens einen Abgaspartikelfilter und teilweise über mindestens einen Katalysator leitbar ist.With the present invention, an exhaust aftertreatment system for an internal combustion engine of a motor vehicle is proposed in which, depending on the operating point of the internal combustion engine, exhaust gas can be conducted either completely via at least one exhaust gas particle filter or partially via at least one exhaust gas particle filter and partly via at least one catalyst.
Durch diese vom Betriebspunkt der Brennkraftmaschine abhängige Beaufschlagung des oder jedes Abgaspartikelfilters und des oder jedes Katalysators mit Abgas kann die Qualität der Abgasnachbehandlung, insbesondere die Verminderung von Abgaspartikelemissionen, weiter gesteigert werden.By this dependent on the operating point of the internal combustion engine loading of the or each exhaust particulate filter and the or each catalyst with exhaust gas, the quality of the exhaust aftertreatment, in particular the reduction of exhaust particulate emissions, can be further increased.
Vorzugweise ist das Abgas der jeweiligen Zylindergruppe bei einem Warmlauf der Brennkraftmaschine und/oder bei einer Teillast der Brennkraftmaschine und/oder bei einer Volllast der Brennkraftmaschine in einem unteren Drehzahlbereich vollständig über den Abgaspartikelfilter leitbar. Bei einer Volllast der Brennkraftmaschine in einem mittleren Drehzahlbereich und/oder bei einer Volllast der Brennkraftmaschine in einem oberen Drehzahlbereich ist das Abgas der jeweiligen Zylindergruppe teilweise über den Abgaspartikelfilter und teilweise über den Katalysator leitbar.Preferably, the exhaust gas of the respective cylinder group in a warm-up of the internal combustion engine and / or at a partial load of the internal combustion engine and / or at a full load of the internal combustion engine in a lower speed range completely over the exhaust particulate filter can be conducted. At a full load of the internal combustion engine in a medium speed range and / or at a full load of the internal combustion engine in an upper speed range, the exhaust gas of the respective cylinder group is partly via the exhaust particulate filter and partly via the catalyst conductive.
Nach einer vorteilhaften Weiterbildung der Erfindung sind der jeweiligen Zylindergruppe mehrere Abgaskrümmer zugeordnet, wobei ein erster Abgaskrümmer von ersten Auslassventilen der Zylinder der Zylindergruppe zum Abgaspartikelfilter und ein zweiter Abgaskrümmer von zweiten Auslassventilen der Zylinder der Zylindergruppe zum Katalysator führt, und wobei entweder die zweiten Auslassventile abhängig vom Betriebspunkt der Brennkraftmaschine zuschaltbar und abschaltbar ausgebildet sind, oder dem zweiten Abgaskrümmer ein Sperrventil zugeordnet ist, welches abhängig vom Betriebspunkt der Brennkraftmaschine geöffnet oder geschlossen ist. Dann, wenn Abgas dem oder jedem Abgaspartikelfilter sowie dem oder jedem Katalysator über getrennte Abgaskrümmer zuführbar ist, ist eine besonders bevorzugte Abgasführung beim erfindungsgemäßen Abgasnachbehandlungssystem möglich.According to an advantageous development of the invention, a plurality of exhaust manifolds are associated with the respective cylinder group, wherein a first exhaust manifold leads from first exhaust valves of the cylinders of the cylinder group to the exhaust particulate filter and a second exhaust manifold of second exhaust valves of the cylinders of the cylinder group to the catalyst, and wherein either the second exhaust valves depending on Operating point of the internal combustion engine can be switched on and switched off, or the second exhaust manifold is associated with a check valve which is open or closed depending on the operating point of the internal combustion engine. Then, if exhaust gas is supplied to the or each exhaust particulate filter and the or each catalyst via separate exhaust manifold, a particularly preferred exhaust system in the exhaust aftertreatment system according to the invention is possible.
Nach einer weiteren vorteilhaften Weiterbildung der Erfindung ist der oder jeder Zylindergruppe jeweils ein Abgasturbolader derart zugeordnet, dass ausschließlich das Abgas der Zylinder, welches über den Abgaspartikelfilter der jeweiligen Abgasnachbehandlungseinrichtung leitbar ist, ausgehend von den Zylindern zunächst über eine Turbine des Abgasturbolader und nach Passieren der Turbine des Abgasturbolader über den Abgaspartikelfilter leitbar ist. Das über den parallel zum Abgaspartikelfilter geschalteten Katalysator geführt Abgas ist nicht über die Turbine des Abgasturboladers geleitet.According to a further advantageous embodiment of the invention, the or each cylinder group in each case an exhaust gas turbocharger is assigned such that only the exhaust gas of the cylinder, which can be conducted via the exhaust gas particulate filter of the respective exhaust aftertreatment device, starting from the cylinders initially via a turbine of the exhaust gas turbocharger and after passing through the turbine the exhaust gas turbocharger via the exhaust particulate filter is conductive. The exhaust gas passed via the catalytic converter connected in parallel with the exhaust gas particle filter is not conducted via the turbine of the exhaust gas turbocharger.
Alternativ sind der jeweiligen Zylindergruppe mehrere Abgaskrümmer und ein Abgasturbolader derart zugeordnet, dass ein erster Abgaskrümmer von ersten Auslassventilen und ein zweiter Abgaskrümmer von zweiten Auslassventilen der Zylinder zu einer Turbine eines Abgasturboladers führt, wobei dem Abgasturbolader ein Bypassventil zugeordnet ist, wobei bei vollständig geöffnetem Bypassventil das über den ersten und zweiten Abgaskrümmer geführte Abgas unter Umgehung des Abgasturboladers vollständig über den Abgaspartikelfilter und bei teilweise geschlossenem Bypassventil unter Umgehung des Abgasturboladers teilweise über den Abgaspartikelfilter und teilweise über die Turbine des Abgasturboladers und nachfolgend über den Katalysator leitbar ist.Alternatively, the respective cylinder group a plurality of exhaust manifold and an exhaust gas turbocharger are assigned such that a first exhaust manifold of the first exhaust valves and a second exhaust manifold of second exhaust valves of the cylinder leads to a turbine of an exhaust gas turbocharger, wherein the exhaust gas turbocharger is associated with a bypass valve, wherein with fully open bypass valve the Exhaust gas guided via the first and second exhaust manifold, bypassing the exhaust gas turbocharger, completely over the exhaust gas particulate filter and partially closed by bypass valve, bypassing the exhaust gas turbocharger partially over the exhaust gas particulate filter and partly through the turbine of Exhaust gas turbocharger and subsequently via the catalyst is conductive.
Durch die Integration mindestens eines Abgasturboladers in das Abgasnachbehandlungssystem kann der Wirkungsgrad der Brennkraftmaschine gesteigert werden.By integrating at least one exhaust gas turbocharger in the exhaust aftertreatment system, the efficiency of the internal combustion engine can be increased.
