Die Erfindung bezieht sich auf eine Brennkraftmaschine mit einem Abgasturbolader nach dem Oberbegriff des Anspruches 1.The The invention relates to an internal combustion engine with an exhaust gas turbocharger according to the preamble of claim 1.

Zugleich ist bei Brennkraftmaschinen, die mit Compound-Nutzturbinen ausgestattet sind, zu berücksichtigen, dass bei einem Betrieb im Teillastgebiet bei aktivierter Abgasführung aufgrund des dadurch verringerten Massendurchsatzes die Compound-Nutzturbine in den Ventilationsbereich geraten kann, in der die Compoundturbine einen negativen Wirkungsgrad hat und Leistung von der Kurbelwelle des Motors zieht. Hierdurch wird der Gesamtwirkungsgrad der Brennkraftmaschine verschlechtert.at the same time is to be considered in internal combustion engines equipped with compound power turbines, that during operation in the partial load area with activated exhaust gas due to the resulting reduced mass flow rate the compound utility turbine can get into the ventilation area in which the compound turbine has a negative efficiency and power from the crankshaft the engine pulls. As a result, the overall efficiency of the internal combustion engine deteriorated.
Der Erfindung liegt die Aufgabe zugrunde, eine Brennkraftmaschine mit Abgasturbolader anzugeben, die sich einerseits durch eine geringe Emission von Stickoxiden und andererseits durch einen guten Gesamtwirkungsgrad auszeichnet.Of the Invention is the object of an internal combustion engine with Specify exhaust gas turbocharger, on the one hand by a small Emission of nitrogen oxides and on the other hand by a good overall efficiency distinguished.
Diese Aufgabe wird erfindungsgemäß mit den Merkmalen des Anspruches 1 gelöst. Die Unteransprüche geben zweckmäßige Weiterbildungen an.These Task is according to the invention with the Characteristics of claim 1 solved. The dependent claims give expedient further education at.
Bei der erfindungsgemäßen Brennkraftmaschine ist in der Abgasrückführleitung, die Teil der Abgasrückführungseinrichtung ist, eine Gaspumpe angeordnet, über die Gas aus dem Abgasstrang in den Ansaugtrakt hinein gefördert werden kann. Da die Gasförderung von Abgasstrang in Ansaugtrakt von der Gaspumpe unterstützt wird, kann eine Abgasrückführung auch in Betriebsbereiche hinein ausgedehnt werden, in denen kein Druckgefälle zwischen Abgasstrang und Ansaugtrakt herrscht bzw. ein derartiges Druckgefälle für eine Gasförderung nicht ausreicht. Die zusätzliche Förderung von Abgas über die Abgasrückführleitung in den Ansaugtrakt hinein ermöglicht in gegenüber dem Stand der Technik größeren Betriebsbereichen eine Reduzierung von Stickoxiden.at the internal combustion engine according to the invention is in the exhaust gas recirculation line, the part of the exhaust gas recirculation device is arranged over a gas pump the gas from the exhaust system are conveyed into the intake can. As the gas extraction is supported by the exhaust gas system in the intake tract of the gas pump, can also have an exhaust gas recirculation be extended into operating areas in which no pressure gradient between Exhaust line and intake system prevails or such a pressure gradient for gas production not sufficient. The additional advancement from exhaust over the exhaust gas recirculation line into the intake tract allows in opposite the prior art larger operating areas a reduction of nitrogen oxides.
Ein weiterer Vorteil liegt darin, dass nunmehr auch stromab der Abgasturbine die Abgasrückführleitung vom Abgasstrang abzweigen kann, ohne dass dies eine Begrenzung des Anwendungsbereiches der Abgasrückführung aufgrund eines mangelnden Druckabfalls zur Folge hätte. Dadurch steht stromauf der Abgasturbine der gesamte Abgasmassenstrom ohne Druckverlust für den Antrieb des Turbinenrades zur Verfügung, was sich vorteilhaft auf den Wirkungsgrad des Abgasturboladers auswirkt. Auch bei niedrigen Lasten und Drehzahlen, in denen nur verhältnismäßig wenig Abgas für den Antrieb der Abgasturbine produziert wird, wird kein Abgas stromauf der Turbine abgezweigt, so dass auch in diesem Betriebszustand der Brennkraftmaschine die Abgasturbine relativ schnell anspricht und ein so genanntes Turboloch vermieden wird. Zugleich kann auch in diesen Betriebsbereichen bereits eine Abgasrückführung durchgeführt werden, da der erforderliche Druck für die Überführung von Abgasstrang in den Ansaugtrakt über die Gaspumpe erzeugt werden kann.One Another advantage is that now also downstream of the exhaust gas turbine the exhaust gas recirculation line branch off from the exhaust system, without this being a limitation of the Scope of application of exhaust gas recirculation due a lack of pressure drop would result. This is upstream the exhaust gas turbine, the entire exhaust gas mass flow without pressure loss for the Drive the turbine wheel available, which is beneficial affects the efficiency of the turbocharger. Even at low Loads and speeds in which only relatively little exhaust gas for the drive the exhaust gas turbine is produced, no exhaust gas is upstream of the turbine branched off, so that even in this operating condition of the internal combustion engine the exhaust gas turbine responds relatively quickly and a so-called turbo lag is avoided. At the same time, even in these operating areas already an exhaust gas recirculation is carried out because the required pressure for the transfer of Exhaust line in the intake via the gas pump can be generated.
Die für den Betrieb der Gaspumpe erforderliche Antriebsleistung kann entweder unmittelbar von der Brennkraftmaschine abgegriffen werden oder über ein zusätzliches Antriebsaggregat, beispielsweise einen Elektromotor, bereitgestellt werden. Die Lösung über das zusätzliche Antriebsaggregat bietet den Vorteil, dass die für den Betrieb der Gaspumpe erforderliche Antriebsleistung unabhängig von der Motorleistung bereitgestellt wird, so dass der Motorwirkungsgrad durch den Betrieb der Gaspumpe nicht beeinträchtigt wird. Der Antrieb der Gaspumpe über die Brennkraftmaschine bzw. einem der Brennkraftmaschine zugeordneten Aggregat bietet andererseits den Vorteil, dass kein zusätzlicher Motor vorgesehen werden muss.The for the Operation of the gas pump required drive power can either be tapped directly from the internal combustion engine or via a additional Drive unit, such as an electric motor, provided become. The solution about that additional Drive unit has the advantage that required for the operation of the gas pump Drive power independent provided by the engine power, so that the engine efficiency is not affected by the operation of the gas pump. The drive of the Gas pump over the Internal combustion engine or one of the internal combustion engine associated On the other hand aggregate offers the advantage that no additional Motor must be provided.
Gemäß einer bevorzugten Weiterbildung, in der die Antriebsenergie für die Gaspumpe direkt von der Brennkraftmaschine abgeleitet wird, ist die Gaspumpe mit einer Compound-Nutzturbine gekoppelt, die ihrerseits mit der Kurbelwelle der Brennkraftmaschine verbunden ist, insbesondere über eine Kupplung und/oder ein Getriebe. Die Compound-Nutzturbine liegt zweckmäßig stromab der Abgasturbine im Abgasstrang und wird von den Abgasen durchströmt, welche bereits die Abgasturbine passiert haben. In der Compound-Nutzturbine kann die in dem Abgas noch enthaltene Restenergie in Antriebsleistung umgesetzt werden, die über die mechanische Kopplung auf die Kurbelwelle der Brennkraftmaschine übertragen wird, wodurch der Gesamtwirkungsgrad der Brennkraftmaschine verbessert wird. Die Abzweigung der Abgasrückführleitung befindet sich vorteilhaft stromab der Compound-Nutzturbine, um sicherzustellen, dass die Restenergie im Abgas ohne Abstriche der Compound-Nutzturbine zugute kommt.According to a preferred embodiment, in the drive energy for the gas pump is derived directly from the internal combustion engine, the gas pump is coupled to a compound utility turbine, which in turn is connected to the crankshaft of the internal combustion engine, in particular via a clutch and / or a transmission. The compound turbine is useful downstream of the exhaust gas turbine in the exhaust system and is traversed by the exhaust gases, which have already passed the exhaust gas turbine. In the compound power turbine, the remaining energy contained in the exhaust gas can be converted into drive power, which is transmitted via the mechanical coupling to the crankshaft of the internal combustion engine, whereby the overall efficiency of the internal combustion engine is improved. The diversion of the exhaust gas recirculation line is advantageously downstream of the compound turbine to ensure that the residual energy in the exhaust gas without compromising the compound turbine benefits.
Der Antrieb der Gaspumpe über die Brennkraftmaschine, insbesondere über die Compound-Nutzturbine, geht zwar mit einer geringfügigen Verringerung des Wirkungsgrades der Compound-Nutzturbine einher; dies wird jedoch durch den Vorteil ausgeglichen, dass der gesamte Abgasmassenstrom die im Abgasstrang befindlichen Turbinen durchströmt, wodurch auch noch in der nachgeschalteten Compound-Nutzturbine in weiten Betriebsbereichen ein für den Antrieb dieser Turbine nutzbares Druckgefälle herrscht. Außerdem kann über die Betätigung der Gaspumpe unabhängig von dem Abgasdruck im Verzweigungspunkt der Abgasrückführleitung die Abgasrückführung durchgeführt werden.Of the Drive the gas pump over the internal combustion engine, in particular via the compound power turbine, goes with a slight reduction the efficiency of the compound power turbine associated; this will however balanced by the advantage that the entire exhaust gas mass flow flows through the turbines located in the exhaust system, whereby even in the downstream compound turbine in wide Operating areas for the drive of this turbine usable pressure gradient prevails. In addition, over the activity the gas pump independently from the exhaust pressure at the branch point of the exhaust gas recirculation line the exhaust gas recirculation are carried out.
Gemäß einer weiteren zweckmäßigen Ausführung ist in der Abgasrückführleitung stromauf der Gaspumpe ein Stellventil angeordnet, über das zum einen der Abgasstrom in die Abgasrückführleitung hinein einstellbar ist und zum anderen auch Frischluft in die Abgasrückführleitung eingespeist werden kann. Die Einspeisung der Frischluft erfolgt alternativ oder zusätzlich zur Rückführung von Abgas. Über das betreffende Stellventil kann das Verhältnis von rückgeführtem Abgasmassenstrom und Frischluftstrom reguliert werden. Das Stellventil stellt eine Dosiereinrichtung dar, über die der Brennkraftmaschine ein weiterer Freiheitsgrad zur Verfügung steht, nämlich die Einstellung des Verhältnisses Lambda von Abgas zu Luft.According to one further expedient embodiment in the exhaust gas recirculation line upstream of the gas pump, a control valve arranged over the on the one hand, the exhaust gas flow into the exhaust gas recirculation line adjustable and on the other fresh air into the exhaust gas recirculation line can be fed. The supply of fresh air takes place alternatively or additionally for the return of Exhaust. About the pertaining control valve can the ratio of recirculated exhaust gas mass flow and Fresh air flow to be regulated. The control valve provides a metering device about that the internal combustion engine has a further degree of freedom available, namely the setting of the ratio Lambda from exhaust to air.
Gemäß einer weiteren vorteilhaften Ausführung ist vorgesehen, dass die Abgasturbine, die Bestandteil des Abgasturboladers ist, mit einer variablen Turbinengeometrie zur veränderlichen Einstellung des wirksamen Turbineneintrittsquerschnitts ausgestattet ist. Die variable Einstellung der Turbinengeometrie erlaubt eine Anpassung sowohl in der befeuerten Antriebsbetriebsweise als auch im Motorbremsbetrieb an die aktuell geltenden Erfordernisse. Beispielsweise kann die variable Turbinengeometrie im Bremsbetrieb in eine den Eintrittsquerschnitt reduzierende Stauposition verstellt werden, um eine Erhöhung des Abgasgegendrucks zu erreichen, so dass die Kolben der Brennkraftmaschine gegen diesen erhöhten Abgasgegendruck Ausschubarbeit leisten müssen.According to one further advantageous embodiment is provided that the exhaust gas turbine, which is part of the exhaust gas turbocharger is variable with a variable turbine geometry Adjustment of the effective turbine inlet cross-section equipped is. The variable setting of the turbine geometry allows one Adaptation in both the fired drive mode and in engine braking operation to the currently applicable requirements. For example can the variable turbine geometry in braking mode in a the Inlet cross-section reducing stowage position be adjusted an increase to achieve the exhaust back pressure, so that the pistons of the internal combustion engine raised against this Exhaust back pressure must perform Ausschubarbeit.
