Eine Brennkraftmaschine weist einen Abgasturbolader auf, dessen Abgasturbine zwei separate Strömungsfluten mit unterschiedlichem Querschnitt besitzt, wobei jede Strömungsflut mit jeweils einer Abgasleitung zur Versorgung mit Abgas der Brennkraftmaschine verbunden ist. Weiterhin ist eine Abgasrückführeinrichtung mit einer Abgasrückführleitung vorgesehen, welche die der kleineren Strömungsflut zugeordnete Abgasleitung mit dem Ansaugtrakt der Brennkraftmaschine verbindet. Die der größeren Strömungsflut zugeordnete Abgasleitung kommuniziert über eine Verbindungsleitung mit der Abgasrückführleitung, wobei in dieser Verbindungsleitung ein unidirektionales Strömungsventil angeordnet ist.An internal combustion engine has an exhaust gas turbocharger, the exhaust gas turbine of which has two separate flow passages with different cross sections, each flow passage being connected to an exhaust pipe for supplying exhaust gas to the internal combustion engine. Furthermore, an exhaust gas recirculation device is provided with an exhaust gas recirculation line, which connects the exhaust passage associated with the smaller flow passage with the intake tract of the internal combustion engine. The exhaust pipe assigned to the larger flow passage communicates via a connecting line with the exhaust gas recirculation line, a unidirectional flow valve being arranged in this connecting line.
Description
Die Erfindung bezieht sich auf eine Brennkraftmaschine mit einem Abgasturbolader und einer Abgasrückführeinrichtung nach dem Oberbegriff des Anspruches 1.The invention relates to a Internal combustion engine with an exhaust gas turbocharger and an exhaust gas recirculation device according to the preamble of claim 1.
Aus der Druckschrift
Von diesem Stand der Technik ausgehend liegt der Erfindung das Problem zugrunde, einen größeren Arbeits- bzw. Betriebsbereich zu ermöglichen, in welchem eine Abgasrückführung durchgeführt werden kann.Starting from this state of the art The invention is based on the problem of a larger working or operating range to allow in which an exhaust gas recirculation are performed can.
Dieses Problem wird erfindungsgemäß mit den Merkmalen des Anspruches 1 gelöst. Die Unteransprüche geben zweckmäßige Weiterbildungen an.This problem is inventively with the Characteristics of claim 1 solved. The dependent claims give expedient further education on.
Erfindungsgemäß ist vorgesehen, dass die teilnehmende Abgasmenge durch Kopplung der Stränge erhöht wird. Hierzu wird diejenige Abgasleitung, welche der größeren der beiden Strömungsfluten zugeordnet ist, über eine Verbindungsleitung entweder direkt oder indirekt mit der Rückführleitung verbunden, wobei in der Verbindungsleitung ein unidirektionales Strömungsventil angeordnet ist, beispielsweise ein Rückschlagventil oder ein Flatterventil, welches den Durchfluss von Abgas durch die Verbindungsleitung nur in Richtung der Rückführleitung freigibt. Das unidirektionale Strömungsventil sperrt dagegen in allen Betriebszuständen einen Rückfluss des Abgases über die Verbindungsleitung zurück in die Abgasleitung. Diese Ausführung ermöglicht es, Druckpulsationen in der der größeren Strömungsflut zugeordneten Abgasleitung trotz eines niedrigeren mittleren Druckniveaus in dieser Abgasleitung für das Überströmen von Abgas auf die Seite der kleineren Strömungsflut bzw. der Abgasrückführeinrichtung auszunutzen, sofern die Druckspitzen in der Abgasleitung der größeren Strömungsflut zeitweise den aktuell herrschenden Druck im Bereich der kleineren Strömungsflut übersteigen. Diese Druckspitzen führen in Kombination mit dem unidirektionalen Strömungsventil zu einem Überströmen von Abgas und einer Erhöhung des Drucks im Bereich der Abgasleitung der kleineren Strömungsflut bzw. der Abgasrückführeinrichtung. Das erhöhte Druckniveau und die teilnehmende, erhöhte Abgasmenge ermöglicht eine Abgasrück führung in einem größeren Betriebsbereich, als dies im Stand der Technik der Fall ist. Hierdurch kann das Abgasverhalten der Brennkraftmaschine verbessert werden.According to the invention, it is provided that the participating Exhaust gas is increased by coupling the strands. This will be the one Exhaust pipe, which is the larger of the both flow tides is assigned over a connection line is connected either directly or indirectly to the return line, wherein in the connecting line, a unidirectional flow valve is arranged, for example, a check valve or a flutter valve, which only allows the flow of exhaust gas through the connecting pipe towards the return line releases. The unidirectional flow valve On the other hand, in all operating states it blocks a backflow of the Exhaust gas over the connection line back in the exhaust pipe. This execution allows it, pressure pulsations in the larger flow of exhaust associated exhaust pipe despite a lower mean pressure level in this exhaust pipe for the overflow of Exploit exhaust gas on the side of the smaller flow flow or exhaust gas recirculation system, provided that the pressure peaks in the exhaust pipe of the larger flow temporarily exceed the currently prevailing pressure in the area of the smaller flow tide. These pressure peaks lead in combination with the unidirectional flow valve to an overflow of Exhaust and an increase the pressure in the region of the exhaust pipe of the smaller flow or the exhaust gas recirculation device. The increased Pressure level and the participating, increased amount of exhaust gas allows a Exhaust gas recirculation in a larger operating area, as is the case in the prior art. This allows the exhaust behavior the internal combustion engine can be improved.
Als Strömungsventil wird zweckmäßig ein selbsttätig arbeitendes Ventil eingesetzt, insbesondere ein Rückschlagventil, welches lediglich in eine Richtung öffnet und in Gegenrichtung sperrt, bzw. ein Flatterventil, das ebenfalls unidirektional arbeitet. Steuernde Eingriffe zur Einstellung des Schaltzustandes des Ventiles sind nicht erforderlich.As a flow valve is advantageously an automatically working Valve used, in particular a check valve, which only opens in one direction and in the opposite direction locks, or a flutter valve, the same works unidirectionally. Controlling interventions for setting the Switching state of the valve are not required.
Gemäß einer ersten vorteilhaften Ausführung liegt die Verbindungsleitung einschließlich dem darin angeordneten, unidirektionalen Strömungsventil zwischen den beiden Abgasleitungen für die größere und die kleinere Strömungsflut der Abgasturbine. Aufgrund des kleineren Querschnittes der kleineren Strömungsflut und des erhöhten Rückstauvermögens herrscht in diesem Teil des Abgasstranges ein höheres, mittleres Druckniveau als in dem der größeren Strömungsflut zugeordneten Teil des Abgasstranges. Die Druckpulsationen, welche sich in die Abgasleitung der größeren Strömungsflut ausbreiten, können in ihrem Spitzenwert den aktuellen Druckwert der gegenüberliegenden Abgasleitung übersteigen, wodurch ein Abgasübertritt über die Verbindungsleitung und das unidirektionale Strömungsventil ermöglicht wird. Da die Abgasrückführleitung von der Abgasleitung der kleineren Strömungsflut abzweigt, kommt das gesteigerte Druckniveau in der Abgasleitung der kleineren Strömungsflut auch der Abgasrückführung zugute.According to a first advantageous execution is the connection line including the arranged therein unidirectional flow valve between the two exhaust pipes for the larger and the smaller flow the exhaust gas turbine. Due to the smaller cross section of the smaller ones flow passage and the heightened Rückstauvermögens prevails in this part of the exhaust line, a higher, medium pressure level than in the larger flow assigned part of the exhaust line. The pressure pulsations, which into the exhaust pipe of the larger flow can spread in their peak the current pressure value of the opposite Exceed exhaust pipe, causing an exhaust gas passage over the Connecting line and the unidirectional flow valve is enabled. Since the exhaust gas recirculation line comes off the exhaust pipe of the smaller flow tide, comes increased pressure level in the exhaust pipe of the smaller flow tide also the exhaust gas recirculation benefit.
Gemäß einer zweiten vorteilhaften Ausführung ist die Verbindungsleitung zwischen der Abgasleitung der größeren Strömungsflut und unmittelbar der Rückführleitung der Abgasrückführeinrichtung angeordnet. Im Leitungsabschnitt zwischen der Abgasleitung der kleineren Strömungsflut und der Abgasrück führleitung kann ebenfalls ein unidirektionales Strömungsventil angeordnet sein, so dass die in dieser Abgasleitung herrschenden Druckspitzen ebenfalls in die Rückführleitung eingespeist werden und somit eine weitere Drucksteigerung in der Abgasrückführeinrichtung erzielt werden kann.According to a second advantageous execution is the connecting line between the exhaust pipe of the larger flow and immediately the return line arranged the exhaust gas recirculation device. In the line section between the exhaust pipe of the smaller flow and the exhaust gas recirculation line can also be arranged a unidirectional flow valve, so that the pressure peaks prevailing in this exhaust pipe also in the return line be fed and thus a further increase in pressure in the Exhaust gas recirculation device can be achieved.
