Dies hat den Vorteil, dass Abgasklappe und Abgasrückführungsventil in einem gemeinsamen, vormontierten Bauteil integriert sind, wobei gleichzeitig hohe Rückführraten insbesondere auch für eine Niederdruck-Abgasrückführung erzielt werden.This has the advantage that exhaust flap and exhaust gas recirculation valve in a common, pre-assembled Component are integrated, while high return rates especially for achieved a low pressure exhaust gas recirculation become.

Bei einer Niederdruck-Abgasrückführung weist die Brennkraftmaschine einen Abgasturbolader mit einem in dem Frischluftstrang angeordneten Verdichter und einer in dem Abgasstrang angeordneten Turbine auf, wobei der Partikelfilter mit dem Abgasrückführungsventil und der Abgasklappe stromab der Turbine des Abgasturboladers in dem Abgasstrang angeordnet ist.at a low pressure exhaust gas recirculation points the internal combustion engine is an exhaust gas turbocharger with a in the fresh air line arranged compressor and arranged in the exhaust line turbine on, wherein the particulate filter with the exhaust gas recirculation valve and the exhaust flap downstream of the turbine of the exhaust gas turbocharger arranged in the exhaust line is.

Die Erfindung wird im folgenden anhand der Zeichnung näher erläutert. Diese zeigt inThe The invention will be explained in more detail below with reference to the drawing. These shows in

2 eine bevorzugte Ausführungsform einer Kombination von Abgasrückführungsventil und Abgasklappe in einem einzigen Bauteil. 2 a preferred embodiment of a combination of exhaust gas recirculation valve and exhaust valve in a single component.

1 zeigt einen Teil einer erfindungsgemäßen Brennkraftmaschine mit einem Frischluftstrang 10 zum Zuführen von Verbrennungsluft an nicht dargestellte Arbeitszylinder der Brennkraftmaschine und einen Abgasstrang 12 zum Abführen von Abgasen aus den Arbeitszylindern der Brennkraftmaschine. Die Brennkraftmaschine weist einen Abgasturbolader 14 mit einer in dem Abgasstrang angeordneten Turbine 16 und einem in dem Frischluftstrang angeordneten Verdichter 18. In den 1 und 2 ist das Abgas mit 34, das rückgeführte Abgas mit 36 und Frischluft mit 38 bezeichnet. 1 shows a part of an internal combustion engine according to the invention with a fresh air line 10 for supplying combustion air to not shown working cylinder of the internal combustion engine and an exhaust line 12 for discharging exhaust gases from the working cylinders of the internal combustion engine. The internal combustion engine has an exhaust gas turbocharger 14 with a turbine arranged in the exhaust system 16 and a compressor disposed in the fresh air line 18 , In the 1 and 2 is the exhaust with 34 , the recirculated exhaust gas with 36 and fresh air with 38 designated.

Stromab der Turbine 16 des Abgasturboladers 14 ist im Abgasstrang 12 ein Partikelfilter 20 angeordnet. Ferner zweigt stromab der Turbine 16 des Abgasturboladers 14 eine Abgasrückführleitung 22 von dem Abgasstrang 12 ab und mündet stromauf des Verdichters des Abgasturboladers 14 in den Frischluftstrang 10. In der Abgasrückführleitung 22 ist ein Abgasrückführventil (AGR-Ventil) 24 angeordnet, welches die Abgasrückführleitung 22 wahlweise öffnet oder schließet, um eine Menge von rückgeführtem Abgas zu steuern. Da die Abgasrückführleitung 22 stromab der Turbine des Abgasturboladers 14 von dem Abgasstrang 12 abzweigt. ist der Druck des Abgases im Vergleich zum Druck vor der Turbine 16 des Abgasturboladers 14 reduziert. Daher spricht man von einer Niederdruck Abgasrückführung (ND-AGR). Durch den niederen Druck des Abgases ist die Rückführrate entsprechend beschränkt. Um höhere Rückführraten für die Abgasrückführung zu erzielen, ist zusätzlich eine Abgasklappe 26 im Abgasstrang stromab des Abzweigs der Abgasrückführleitung 22 vorgesehen, die wahlweise einen Strömungsquerschnitt des Abgasstranges 12 verengt, um einen Druck des Abgases im Bereich der Abzweigung der Abgasrückführleitung 22 von dem Abgasstrang 12 zu erhöhen.Downstream of the turbine 16 the exhaust gas turbocharger 14 is in the exhaust system 12 a particle filter 20 arranged. Further branches downstream of the turbine 16 the exhaust gas turbocharger 14 an exhaust gas recirculation line 22 from the exhaust system 12 from and opens upstream of the compressor of the exhaust gas turbocharger 14 in the fresh air line 10 , In the exhaust gas recirculation line 22 is an exhaust gas recirculation valve (EGR valve) 24 arranged, which the exhaust gas recirculation line 22 optionally opens or closes to control a quantity of recirculated exhaust gas. Since the exhaust gas recirculation line 22 downstream of the turbine of the exhaust gas turbocharger 14 from the exhaust system 12 branches. is the pressure of the exhaust gas compared to the pressure in front of the turbine 16 the exhaust gas turbocharger 14 reduced. Therefore, one speaks of a low pressure exhaust gas recirculation (ND-EGR). Due to the low pressure of the exhaust gas, the return rate is correspondingly limited. In order to achieve higher recirculation rates for exhaust gas recirculation, there is also an exhaust gas flap 26 in the exhaust line downstream of the branch of the exhaust gas recirculation line 22 provided, which optionally has a flow cross section of the exhaust line 12 narrows to a pressure of the exhaust gas in the region of the branch of the exhaust gas recirculation line 22 from the exhaust system 12 to increase.

Erfindungsgemäß sind das AGR-Ventil 24 und die Abgasklappe 26 in den Partikelfilter 20 integriert angeordnet, wie mit gestrichelter Linie 28 angedeutet. Hierdurch bilden die Bauteile Partikelfilter 20, AGR-Ventil 24, Abgasklappe 26 und zumindest ein Teil der Abgasrückführleitung 22 ein vormontiertes Bauteil bzw. Modul aus, dass eine vereinfachte Montage der Brennkraftmaschine erlaubt.According to the invention, the EGR valve 24 and the exhaust flap 26 in the particle filter 20 inte arranged as a dashed line 28 indicated. As a result, the components form particle filters 20 , AGR valve 24 , Exhaust flap 26 and at least a part of the exhaust gas recirculation line 22 a pre-assembled component or module that allows a simplified assembly of the internal combustion engine.

In der dargestellten, beispielhaften Ausführungsform ist in der Abgasrückführleitung 22 ein Kühler 30 für rückgeführtes Abgas (AGR-Kühler) angeordnet.In the illustrated exemplary embodiment, in the exhaust gas recirculation line 22 a cooler 30 for recirculated exhaust gas (EGR cooler) arranged.

Es besteht weiterhin die Möglichkeit, das AGR-Ventil 24 und die Abgasklappe 26 in einem Bauteil zusammenzufassen, wie mit gestrichelter Linie 32 angedeutet. Dieses vormontierte Bauteil bzw. Modul wird hinter dem Partikelfilter angeordnet.There is still the possibility of the EGR valve 24 and the exhaust flap 26 in a component, as in dashed line 32 indicated. This pre-assembled component or module is arranged behind the particle filter.

In einer bevorzugten Weiterbildung der Erfindung sind das AGR-Ventil und die Abgasklappe zu einem einzigen Drehschieber 32 zusammengefasst, wie in 2 dargestellt. Dieser Drehschieber 32 ist an der Abzweigung der Abgasrückführleitung 22 von dem Abgasstrang 12 angeordnet. Der Drehschieber 32 übt gleichzeitig beide Funktion von AGR-Ventil und Abgasklappe aus, d.h. er öffnet wahlweise die Abgasrückführleitung 22 zum Rückführen von Abgas in den Frischluftstrang 10 und verengt gleichzeitig den Strömungsquerschnitt des Abgasstranges 12 um so mehr, je weiter der Zugang zur Abgasrückführleitung 22 geöffnet wird, so dass sich der Abgasgegendruck im Bereich der Abzweigung der Abgasrückführleitung 22 erhöht und eine höhere Strömungsrate von Abgas in die Abgasrückführleitung 22 erzielt wird.In a preferred embodiment of the invention, the EGR valve and the exhaust valve to a single rotary valve 32 summarized as in 2 shown. This rotary valve 32 is at the branch of the exhaust gas recirculation line 22 from the exhaust system 12 arranged. The rotary valve 32 at the same time performs both function of EGR valve and exhaust valve, ie he opens either the exhaust gas recirculation line 22 for returning exhaust gas into the fresh air line 10 and simultaneously narrows the flow cross-section of the exhaust line 12 the more, the further the access to the exhaust gas recirculation line 22 is opened, so that the exhaust back pressure in the region of the branch of the exhaust gas recirculation line 22 increases and a higher flow rate of exhaust gas into the exhaust gas recirculation line 22 is achieved.
