Auch wenn die gattungsgemäße zweistufige Abgasturboaufladung keine prinzipiellen Nachteile aufweist, liegt der Erfindung die Aufgabe zugrunde, die Dynamik der Abgasturboaufladung weiter zu verbessern, insbesondere bei einer Beschleunigung aus dem Leerlauf der Brennkraftmaschine.Also if the generic two-stage turbocharger has no principal disadvantages, the invention is the The task is to further increase the dynamics of turbocharging improve, especially when accelerating from idle the internal combustion engine.
Diese Aufgabe ist durch das Merkmal im kennzeichnenden Teil des Patentanspruchs 1 gelöst.These The object is achieved by the feature in the characterizing part of the claim 1 solved.
In vorteilhafter Weise wird die Beschleunigung der Brennkraftmaschine insbesondere aus dem Leerlauf heraus zu höheren Drehzahlen hin wesentlich verbessert. Die Umgehung des Niederdruckverdichters bringt den Vorteil eines besseren Ladedruckaufbaues im Dynamikfall und bietet auch stationär im Niedriglastbereich einen Verbrauchsvorteil. Dies bedeutet:
- – einen Vorteil im Trade-off Verhalten bezüglich Verbrauch und Emissionen,
- – deutlich verbessertes Beschleunigungsverhalten des Fahrzeuges aus Niedriglastbereichen.
- - an advantage in trade-off behavior in terms of consumption and emissions,
- - Significantly improved acceleration behavior of the vehicle from low-load areas.
Durch die Ausgestaltung gemäß Patentanspruch 2 ist es möglich, ab einer, von Brennkraftmaschine zu Brennkraftmaschine evtl. unterschiedlichen Drehzahl den Bypass zu verschließen, um den Niederdruckverdichter voll ausnutzen zu können.By the embodiment according to claim 2 is possible, from one, from internal combustion engine to internal combustion engine possibly different speed to close the bypass, to fully exploit the low pressure compressor.
Die Ausgestaltungen gemäß Patentanspruch 3 sind besonders bevorzugt und in der Praxis bewährt.The Embodiments according to claim 3 are particularly preferred and proven in practice.
Durch die Ausgestaltung gemäß Patentanspruch 4 kann ein exakter Verbrennungsluftdurchsatz durch den zweiten Hochdruckverdichter eingestellt werden.By The embodiment according to claim 4 can an exact combustion air flow through the second high pressure compressor be set.
Die Feineinstellung des Verbrennungsluftdurchsatzes durch den Hochdruckverdichter kann in vorteilhafter Weise gemäß Patentanspruch 5 ebenfalls geregelt oder gesteuert werden.The Fine adjustment of the combustion air flow through the high pressure compressor can advantageously according to claim 5 are also regulated or controlled.
Durch die Ausgestaltung gemäß Patentanspruch 6 wird die Hochdruckturbine des zweiten Abgasturboladers ständig auf einer definierten Drehzahl gehalten. Dies verbessert die dynamischen Eigenschaften der erfindungsgemäßen Abgasturboaufladung.By the embodiment according to claim 6 becomes the high-pressure turbine of the second exhaust gas turbocharger constantly held at a defined speed. This improves the dynamic Characteristics of the exhaust turbocharger according to the invention.
Durch die Ausgestaltung gemäß Patentanspruch 7 ist der zweite Hochdruckabgasturbolader jederzeit zu- oder abschaltbar.By the embodiment according to claim 7 is the second high-pressure turbocharger always on or off.
Mit der Ausgestaltung gemäß der Patentansprüche 8 und 9 wird die geförderte Ladeluft abgekühlt, wodurch ein besserer Füllgrad der Brennkraftma schine erzielt wird und gleichzeitig der Wirkungsgrad der Brennkraftmaschine verbessert wird.With the embodiment according to the claims 8 and 9, the conveyed charge air is cooled, whereby a better degree of filling of the internal combustion engine achieved is and at the same time improves the efficiency of the internal combustion engine becomes.
Im Folgenden ist die Erfindung anhand eines bevorzugten Ausführungsbeispieles in einer einzigen Figur näher erläutert.in the The invention is based on a preferred embodiment explained in more detail in a single figure.
