Description
Die vorliegende Erfindung betrifft ein Kraftfahrzeug mit einem Verbrennungsmotor, einem Zuluftstrang, einem Abgastrakt, einem vom Abgastrakt zum Zuluftstrang führenden Niederdruck-Abgasrückführungsstrang und einem im Zuluftstrang angeordneten ersten Verdichter.The present invention relates to a motor vehicle having an internal combustion engine, a supply air line, an exhaust tract, a low-pressure exhaust gas recirculation train leading from the exhaust tract to the supply air line and a first compressor arranged in the supply air line.
Aus der
Der vorliegenden Erfindung liegt die Aufgabe zugrunde, ein Kraftfahrzeug mit Verbrennungsmotor und verbesserter Abgasrückführung bereitzustellen.The present invention has for its object to provide a motor vehicle with internal combustion engine and improved exhaust gas recirculation.
Gelöst wird diese Aufgabe mit einem Kraftfahrzeug nach Anspruch 1. Vorteilhafte Weiterbildungen der Erfindung sind in den Unteransprüchen angegeben und in der Beschreibung beschrieben.This object is achieved with a motor vehicle according to claim 1. Advantageous developments of the invention are specified in the subclaims and described in the description.
Das erfindungsgemäße Kraftfahrzeug umfasst einen Verbrennungsmotor, einen Zuluftstrang, einen Abgastrakt, einen vom Abgastrakt zum Zuluftstrang führenden Abgasrückführungsstrang und einen im Zuluftstrang angeordneten ersten Verdichter. Dabei ist im Abgastrakt eine Abgasnachbehandlungseinrichtung angeordnet und der Abgasrückführungsstrang ist stromabwärts der Abgasnachbehandlungseinrichtung mit dem Abgastrakt verbunden. Der Abgasrückführungsstrang ist mithin ein Niederdruck-Abgasrückführungsstrang. Erfindungsgemäß weist das Kraftfahrzeug zudem einen im Abgasrückführungsstrang angeordneten zweiten Verdichter auf.The motor vehicle according to the invention comprises an internal combustion engine, a supply air line, an exhaust tract, an exhaust gas recirculation train leading from the exhaust tract to the supply air line, and a first compressor arranged in the supply air line. In this case, an exhaust gas aftertreatment device is arranged in the exhaust tract and the exhaust gas recirculation train is connected to the exhaust gas tract downstream of the exhaust gas aftertreatment device. The exhaust gas recirculation train is therefore a low-pressure exhaust gas recirculation train. According to the invention, the motor vehicle also has a second compressor arranged in the exhaust gas recirculation line.
Damit ist es vorteilhaft ermöglicht, den ersten Verdichter kleiner auszuführen, sodass dieser eine geringere Trägheit für ein schnelles Ansprechen aufweist. Thus, it is advantageously possible to make the first compressor smaller, so that it has a lower inertia for a fast response.
Mit dieser Ausgestaltung ist es ermöglicht, mittels des Niederdruck-Abgasrückführungsstrangs eine Hochdruck-Abgasrückführung zu betreiben. Ein zusätzlicher Hochdruck-Abgasrückführungsstrang kann eingespart werden. Es können hohe Abgasrückführungsraten und hohe Temperaturlevel erzielt werden, ohne die Zuluft zu drosseln.With this embodiment, it is possible to operate by means of the low-pressure exhaust gas recirculation line a high-pressure exhaust gas recirculation. An additional high pressure exhaust gas recirculation train can be saved. High exhaust gas recirculation rates and high temperature levels can be achieved without throttling the supply air.
In einer vorteilhaften Ausgestaltung des erfindungsgemäßen Kraftfahrzeugs weist der Abgastrakt einen ersten Abgasstrang und eine in dem ersten Abgasstrang angeordnete erste Abgasturbine auf, die drehmomentübertragend mit dem ersten Verdichter verbunden ist.In an advantageous embodiment of the motor vehicle according to the invention, the exhaust gas tract has a first exhaust gas line and a first exhaust gas turbine arranged in the first exhaust gas line, which is connected with the first compressor in order to transmit torque.
Der erste Verdichter ist damit Teil eines Abgasturboladers. Die Energie zum Antrieb des ersten Verdichters kann somit vorteilhaft dem Abgas entzogen werden.The first compressor is thus part of an exhaust gas turbocharger. The energy for driving the first compressor can thus be advantageously removed from the exhaust gas.
In einer weiteren vorteilhaften Ausgestaltung des erfindungsgemäßen Kraftfahrzeugs weist die erste Abgasturbine eine variable Turbinengeometrie auf. Die Abgasturbine ist dabei mit verstellbaren Leitschaufeln versehen.In a further advantageous embodiment of the motor vehicle according to the invention, the first exhaust gas turbine has a variable turbine geometry. The exhaust gas turbine is provided with adjustable guide vanes.
Damit kann die Abgasturbine in einem breiteren Bereich und effektiver betrieben werden.Thus, the exhaust gas turbine can be operated in a wider range and more effectively.
In einer weiteren vorteilhaften Ausgestaltung des erfindungsgemäßen Kraftfahrzeugs weist der Abgastrakt einen zweiten Abgasstrang und eine in dem zweiten Abgasstrang angeordnete zweite Abgasturbine auf, die drehmomentübertragend mit dem zweiten Verdichter verbunden ist.In a further advantageous embodiment of the motor vehicle according to the invention, the exhaust gas tract has a second exhaust gas line and a second exhaust gas turbine arranged in the second exhaust gas line, which is connected to the second compressor in order to transmit torque.
Der zweite Verdichter ist damit Teil eines Abgasturboladers. Die Energie zum Antrieb des zweiten Verdichters kann somit vorteilhaft dem Abgas entzogen werden.The second compressor is thus part of an exhaust gas turbocharger. The energy for driving the second compressor can thus be advantageously removed from the exhaust gas.
In einer alternativen vorteilhaften Ausgestaltung des erfindungsgemäßen Kraftfahrzeugs ist der zweite Verdichter mit einem Motor drehmomentübertragend verbunden. Der Motor ist insbesondere ein Elektromotor.In an alternative advantageous embodiment of the motor vehicle according to the invention, the second compressor is connected to transmit torque to a motor. The engine is in particular an electric motor.
Der zweite Verdichter ist damit Teil eines motorbetriebenen Turboladers, der unabhängig vom Zustand des Abgases betrieben werden kann. The second compressor is thus part of a motor-driven turbocharger, which can be operated independently of the state of the exhaust gas.
In einer weiteren vorteilhaften Ausgestaltung des erfindungsgemäßen Kraftfahrzeugs umfasst das Kraftfahrzeug einen im Zuluftstrang stromabwärts des ersten Verdichters angeordneten Ladeluftkühler.In a further advantageous embodiment of the motor vehicle according to the invention, the motor vehicle comprises a charge air cooler arranged in the supply air line downstream of the first compressor.
Damit ist es ermöglicht, die Ladeluft, die aus Zuluft oder Zuluft und Abgas besteht zu kühlen. Die gesenkte Temperatur und damit erhöhte Dichte der Ladeluft ermöglicht eine bessere Füllung der Zylinder. Durch die gesenkte Temperatur kann der Verbrennungsmotor zudem mit einer höheren Verdichtung betrieben werden.This makes it possible to cool the charge air, which consists of supply air or supply air and exhaust gas. The lowered temperature and thus increased density of the charge air allows a better filling of the cylinder. Due to the reduced temperature of the internal combustion engine can also be operated with a higher compression.
In einer weiteren vorteilhaften Ausgestaltung des erfindungsgemäßen Kraftfahrzeugs umfasst das Kraftfahrzeug einen im Abgasrückführungsstrang stromaufwärts des zweiten Verdichters angeordneten Abgaskühler.In a further advantageous embodiment of the motor vehicle according to the invention, the motor vehicle comprises an exhaust gas cooler arranged in the exhaust gas recirculation train upstream of the second compressor.
Damit ist es ermöglicht, das zurückgeführte Abgas vor dem Einbringen in den Zuluftstrang zu kühlen.This makes it possible to cool the recirculated exhaust gas prior to introduction into the Zuluftstrang.
In einer weiteren vorteilhaften Ausgestaltung des erfindungsgemäßen Kraftfahrzeugs ist der Abgasrückführungsstrang ausgebildet, Abgas an einer stromaufwärts des ersten Verdichters angeordneten ersten Einlassstelle in den Zuluftstrang einzulassen.In a further advantageous embodiment of the motor vehicle according to the invention, the exhaust gas recirculation line is designed to admit exhaust gas at a first inlet point arranged upstream of the first compressor into the supply air line.
Damit kann zusätzlich eine Niederdruck-Abgasrückführung ausgeführt werden.Thus, in addition, a low-pressure exhaust gas recirculation can be performed.
In einer weiteren vorteilhaften Ausgestaltung des erfindungsgemäßen Kraftfahrzeugs ist der Abgasrückführungsstrang ausgebildet, Abgas an einer stromabwärts des ersten Verdichters angeordneten zweiten Einlassstelle in den Zuluftstrang einzulassen.In a further advantageous embodiment of the motor vehicle according to the invention, the exhaust gas recirculation line is designed to admit exhaust gas at a second inlet point arranged downstream of the first compressor into the supply air line.
Dadurch ist es ermöglicht, insbesondere bei mittlerer Last des Verbrennungsmotors eine ungewünschte Kondensation stromaufwärts des ersten Verdichters zu vermieden. Das zurückgeführte, in den Zuluftstrang eingebrachte Abgas kann zusammen mit der Zuluft im Ladeluftkühler gekühlt werden. Zudem kann bei hoher Last des Verbrennungsmotors das zurückgeführte Abgas am ersten Verdichter vorbeigeleitet werden und dennoch anschließend vom Ladeluftkühler gekühlt werden.This makes it possible, especially at medium load of the internal combustion engine to avoid unwanted condensation upstream of the first compressor. The recirculated exhaust gas introduced into the supply air duct can be cooled together with the supply air in the intercooler. In addition, at high load of the internal combustion engine, the recirculated exhaust gas can be routed past the first compressor and yet be cooled by the charge air cooler.
In einer weiteren vorteilhaften Ausgestaltung des erfindungsgemäßen Kraftfahrzeugs ist der Abgasrückführungsstrang ausgebildet, Abgas an einer stromabwärts des Ladeluftkühlers angeordneten dritten Einlassstelle in den Zuluftstrang einzulassen.In a further advantageous embodiment of the motor vehicle according to the invention, the exhaust gas recirculation line is designed to admit exhaust gas at a third inlet point arranged downstream of the charge air cooler into the supply air line.
Dadurch ist es ermöglicht, insbesondere bei geringer Last des Verbrennungsmotors das zurückgeführte Abgas mit einer hohen Temperatur in den Zuluftstrang einzubringen.This makes it possible to introduce the recirculated exhaust gas at a high temperature in the Zuluftstrang especially at low load of the internal combustion engine.
