der Druckschrift
Im Verdichter des Abgasturboladers ist ein Zusatzkanal ausgebildet, welcher sich etwa parallel zum axialen Verdichtereinlasskanal erstreckt, in dem das Verdichterrad drehbar gelagert ist. Der Zusatzkanal mündet in Höhe des Verdichterrades radial von außen in den Verdichtereinlasskanal, so dass über den Zusatzkanal zugeführte Verbrennungsluft unmittelbar auf die Verdichterradschaufeln auftrifft und das Verdichterrad mit einem antreibenden Drehimpuls beaufschlagt. Hierdurch ist es möglich, in bestimmten Betriebszuständen der Brennkraftmaschine – insbesondere bei niedriger Last- und Drehzahl – den Verdichter im Turbinenbetrieb zu betreiben und dem Verdichterrad zusätzliche Drehenergie zuzuführen, wodurch Drehzahlschwankungen im Verdichterbetrieb reduziert werden können. Dieser Eingriff in die Begrenzung der Drehzahlschwankung des Abgasturboladers ist jedoch auf den niederen Last- und Drehzahlbereich der Brennkraftmaschine beschränkt, bei dem der Ansaugdruck im Ansaugtrakt stromab des Verdichters geringer ist als der Umgebungsdruck, wodurch das für den Turbinenbetrieb erforderliche Druckgefälle zustande kommt.in the Compressor of the exhaust gas turbocharger is an additional channel formed which extends approximately parallel to the axial compressor inlet channel, in which the compressor wheel is rotatably mounted. The additional channel opens into Height of Compressor wheel radially from the outside in the compressor inlet channel, so that via the additional channel supplied combustion air impinges directly on the compressor wheel blades and the compressor wheel subjected to a driving angular momentum. This is it possible, in certain operating conditions the internal combustion engine - in particular at low load and speed - the compressor in turbine mode operate and supply the compressor wheel additional rotational energy, thereby Speed fluctuations in the compressor operation can be reduced. This Intervention in the limitation of the speed fluctuation of the exhaust gas turbocharger However, it is on the low load and speed range of the engine limited, in which the intake pressure in the intake tract downstream of the compressor is lower is the ambient pressure, thereby providing the pressure differential required for turbine operation comes.

Der Erfindung liegt das Problem zugrunde, den Wirkungsgrad und die Betriebssicherheit von aufgeladenen Brennkraftmaschinen zu verbessern. Es sollen insbesondere geringere Drehzahlschwankungen im Abgasturbolader der Brennkraftmaschine erreicht werden.Of the Invention is based on the problem, the efficiency and reliability of supercharged internal combustion engines. It should in particular achieved lower speed fluctuations in the exhaust gas turbocharger of the internal combustion engine become.
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 at.
Erfindungsgemäß ist die Abgasrückführeinrichtung der Brennkraftmaschine mit dem Verdichter in der Weise gekoppelt, dass Abgas aus dem Abgasstrang in einen Zusatzkanal des Verdichters eingeleitet werden kann. Dieser Zusatzkanal ist separat vom axialen Verdichtereinlasskanal ausgeführt, über den der Hauptmassenstrom der Verbrennungsluft auf das Verdichterrad geleitet und durch die Rotation des Rades auf den erhöhten Ladedruck komprimiert wird. Die separate Ausbildung des Zusatzkanals, der insbesondere druck- und strömungsdicht gegenüber dem axialen Verdichtereinlasskanal abgedichtet ist, ermöglicht eine gezielte Anströmung des Verdichterrades mit den Abgasen aus dem Abgasstrang, derart, dass die Verdichterradschaufeln mit einem Drehimpuls beaufschlagt werden und die Abgasenergie in wirksamer Weise in Rotationsenergie des Ver dichterrades umgesetzt werden kann. Die Abgasrückführung dient als Antriebsquelle für das Verdichterrad, wobei der Wirkungsgrad im Unterschied zu Ausführungen aus dem Stand der Technik auf Grund der gezielteren Anströmung des Verdichterrades entscheidend verbessert ist.According to the invention Exhaust gas recirculation device the internal combustion engine coupled to the compressor in such a way that exhaust from the exhaust line into an additional channel of the compressor can be initiated. This additional channel is separate from the axial one Compressor inlet channel executed via the Main mass flow of combustion air passed to the compressor wheel and compressed by the rotation of the wheel to the increased boost pressure becomes. The separate formation of the additional channel, in particular pressure and flow tight compared to the axial compressor inlet channel is sealed, allows a targeted flow the compressor wheel with the exhaust gases from the exhaust line, such that the compressor wheel blades are subjected to an angular momentum and the exhaust gas energy efficiently into rotational energy of the Ver denserrades can be implemented. The exhaust gas recirculation is used as a drive source for the compressor wheel, the efficiency unlike designs from the prior art due to the more targeted flow of the Compressor wheel is significantly improved.
Durch die unmittelbare Einspeisung des stromab einer Abgasreinigungseinheit dem Abgasstrang entnommenen Abgases in den Zusatzkanal des Verdichters wird der Vorteil einer Stickoxid-Reduzierung durch eine Niederdruck-Abgasrückführung mit dem Vorteil der Reduzierung der Drehzahlschwankung im Abgasturbolader verbunden. Insbesondere im niedrigen Last-/Drehzahlbereich der Brennkraftmaschine, kann über den Zusatzkanal das Abgas eingespeist werden, welches auf Grund der Druckdifferenz zwischen dem Druck nach der Abgasreinigungseinheit, welcher nahezu einem Umgebungsdruck entspricht, und Ladedruck das Verdichterrad mit einem antreibenden Drehimpuls beaufschlagt, so dass das Verdichterrad im Turbinenbetrieb gefahren wird; diese Betriebsweise kann auch als Kaltluft-Turbinenbetrieb bezeichnet werden. Vorteilhafterweise ist für diesen Betrieb zusätzlich die Abgastemperatur zur Erhöhung eines Enthalpieangebotes am Verdichterrad zu nutzen.Due to the direct feed of the downstream of an exhaust gas purification unit the exhaust gas taken exhaust gas into the additional channel of the compressor, the advantage of a nitrogen oxide Redu tion by a low-pressure exhaust gas recirculation with the advantage of reducing the speed fluctuation in the exhaust gas turbocharger. In particular, in the low load / speed range of the internal combustion engine, the exhaust gas can be fed via the additional channel, which acts on the compressor wheel with a driving angular momentum due to the pressure difference between the pressure after the exhaust gas cleaning unit, which corresponds to almost an ambient pressure, and the boost pressure Compressor is operated in turbine mode; This mode of operation can also be referred to as cold-air turbine operation. Advantageously, the exhaust gas temperature to increase an Enthalpieangebotes on the compressor to use for this operation in addition.
Gemäß einer bevorzugten Weiterbildung befindet sich im Mündungsbereich des Zusatzkanals in den Verdichtereinlasskanal eine Dralleinrichtung, über die der über den Zusatzkanal zugeführte Massenstrom mit einem Drall beaufschlagt wird, unter dem der Massenstrom auf das Verdichterrad auftrifft und der eine bessere Umsetzung der kinetischen Energie des zugeführten Massenstromes in Rotationsenergie des Verdichterrades ermöglicht. Die Dralleinrichtung kann verstellbar ausgeführt sein, zweckmäßig zwischen einer den Mündungsquerschnitt maximierenden Öffnungsposition und einer den Mündungsquerschnitt absperrenden Schließposition. Über die Einstellung der Drall einrichtung kann der den Zusatzkanal durchströmende Abgasmassenstrom reguliert werden, so dass prinzipiell auf ein Abgasrückführventil in der Abgasrückführeinrichtung verzichtet werden kann. Andererseits kann es aber zweckmäßig sein, ein derartiges Abgasrückführventil zusätzlich zu der verstellbaren Dralleinrichtung vorzusehen, was den Vorteil bietet, dass Betriebszustände einstellbar sind, in welchen die Rückführung von Abgas in den Abgasstrang unterbunden wird, zugleich aber Verbrennungsluft über den Zusatzkanal auf das Verdichterrad geleitet wird und der Verdichter im Kaltluft-Turbinenbetrieb betrieben wird.According to one preferred development is located in the mouth area of the additional channel in the compressor inlet passage a swirl device, via the the over the additional channel supplied Mass flow is applied to a swirl, below the mass flow impinges on the compressor wheel and the better implementation of the kinetic energy of the supplied Mass flow in rotational energy of the compressor wheel allows. The swirl device can be made adjustable, expedient between one the mouth cross-section maximizing opening position and one the mouth cross-section shut off closing position. About the Setting the swirl device can the exhaust passage through the additional exhaust gas mass flow be regulated, so in principle to an exhaust gas recirculation valve dispensed in the exhaust gas recirculation device can be. On the other hand, it may be appropriate, such an exhaust gas recirculation valve in addition to provide the adjustable swirl device, which offers the advantage that operating conditions are adjustable, in which the return of exhaust gas in the exhaust system is prevented, but at the same time combustion air over the Additional channel is routed to the compressor wheel and the compressor in the Cold air turbine operation is operated.
Es ist aber auch möglich, eine feste Dralleinrichtung ohne Verstellmöglichkeit im Mündungsbereich von Zusatzkanal und Verdichtereinlasskanal vorzusehen. Eine Regulierung des Abgasmassenstromes erfolgt in diesem Fall zweckmäßig über ein einstellbares Abgasrückführventil.It but it is also possible a solid twisting device without adjustment in the mouth area to provide additional channel and compressor inlet channel. A regulation the exhaust gas mass flow takes place in this case expediently via an adjustable Exhaust gas recirculation valve.
Der Zusatzkanal verläuft vorteilhaft radial nach außen versetzt zum Verdichtereinlasskanal und erstreckt sich parallel zu diesem. Der Mündungsbereich liegt zweckmäßig axial im Bereich des Verdichterrades, wobei der Zusatzkanal insbesondere radial in den Verdichtereinlasskanal einmündet, so dass der durch den Zusatzkanal geleitete Massenstrom unter Berücksichtigung des über die Dralleinrichtung erzeugten Dralls in einer einen Drehimpuls auf das Verdichterrad übertragenden Weise auf Letzteres auftrifft.Of the Additional channel runs advantageously radially outward offset to the compressor inlet channel and extends parallel to this. The mouth area is appropriate axially in the region of the compressor wheel, wherein the additional channel in particular opens radially into the compressor inlet passage, so that through the Additional channel directed mass flow taking into account the over the Swirl generated spin in one angular momentum transmit the compressor wheel Way on the latter hits.
Bei einer verstellbaren Dralleinrichtung besteht dieses zweckmäßig aus einem feststehenden Drallgitter, welches den Mündungsbereich überdeckt, sowie einem verstellbaren Axialschieber, der in den Mündungsbereich einschiebbar ist und hierdurch den Mündungsquerschnitt verschließt.at an adjustable swirl device consists of this expedient a fixed swirl grid, which covers the mouth area, as well as an adjustable axial slide, which can be inserted into the mouth area is and thereby the mouth cross-section closes.
Der Verdichter ist bevorzugt Teil eines Abgasturboladers, wobei die Abgasturbine gegebenenfalls mit einer variabel einstellbaren Turbinengeometrie zur Einstellung des Turbineneintrittsquerschnitts ausgestattet sein kann. Grundsätzlich ist es aber auch möglich, den Verdichter unabhängig von einer Abgasturbine anzutreiben, beispielsweise über einen Elektromotor; in diesem Fall wird eine Abgasturbine nicht benötigt.Of the Compressor is preferably part of an exhaust gas turbocharger, wherein the Exhaust gas turbine optionally with a variably adjustable turbine geometry be equipped to adjust the turbine inlet cross section can. in principle but it is also possible the compressor independent to be driven by an exhaust gas turbine, for example via an electric motor; In this case, an exhaust gas turbine is not needed.
