Abstract
Description
Die Erfindung betrifft gemäß dem Oberbegriff des Patentanspruches 1 eine Drallerzeugungseinrichtung zur drallbeaufschlagten Anströmung eines Verdichterlaufrades eines Verdichters mit einem Verdichtergehäuse und einer Ladeluftsaugleitung insbesondere für ein Kraftfahrzeug mit einer aufgeladenen Brennkraftmaschine.According to the preamble of the invention Claim 1 a swirl generator for swirl inflow a compressor impeller of a compressor with a compressor housing and a charge air suction line especially for a motor vehicle with a supercharged internal combustion engine.
In Hinblick auf eine Leistungssteigerung und/oder zur Verbesserung des Wirkungsgrades sowie auch der Abgasqualität ist es bekannt, Brennkraftmaschinen mit verdichteter Luft zu beaufschlagen; in diesem Zusammenhang haben sich beispielsweise abgasgetriebene Turbolader bewährt.With regard to an increase in performance and / or it is to improve the efficiency as well as the exhaust gas quality known to apply compressed air to internal combustion engines; in this context, for example, have been driven by exhaust gases Turbocharger proven.
Der Betrieb derartiger Verdichter erfolgt aufgrund der besseren Dynamikeigenschaften häufig nahe der Pumpgrenze im Verdichterkennfeld, was allerdings akustische Nachteile in Form sehr störender Zischgeräusche bedingt, gegebenenfalls führt die Instabilität bei länger andauerndem Betrieb in diesem Bereich sogar zu Schäden am Verdichterlaufrad. Ferner ist der Betrieb im Bereich der Pumpgrenze in besonderem Maße verlustbehaftet, so dass sich ein sehr schlechter Wirkungsgrad ergibt.Operation of such compressors is often close due to the better dynamic properties the surge limit in the compressor map, but this is acoustic Disadvantages in the form of very disturbing hissing noises, possibly leads the instability with longer continuous operation in this area can even damage the compressor impeller. Furthermore, the operation in the area of the surge limit is particularly lossy, so that there is a very poor efficiency.
Eine Möglichkeit zur Abhilfe besteht im geregelten Betrieb von Abgasturboladern, wobei zwischen turbinen- und verdichterseitiger Regelung unterschieden wird. Im Rahmen einer verdichterseitigen Regelung können dem Verdichterlaufrad vorgeordnete Luftleitgitter zur Anwendung kommen.There is a way to remedy this in the regulated operation of exhaust gas turbochargers, whereby between turbine and compressor-side regulation is distinguished. As part of a compressor-side regulation can air guide grilles upstream of the compressor impeller come.
Beispielsweise beeinflusst ein verdichtereingangsseitig angeordneter Drallerzeuger am Verdichtereintritt die Strömungsrichtung der Luft derart, dass es im kritischen Kennfeldbereich zu einer Reduktion der Eintrittsstoßverluste am Schaufelrad kommt. Es wird somit eine vorteilhafte Verschiebung der Pumpgrenze in Richtung kleinerer Massenströme erreicht.For example, one affects the compressor inlet side arranged swirl generator at the compressor inlet the flow direction the air in such a way that it becomes a critical map area Reduction of entry impact losses comes on the paddle wheel. It will therefore be an advantageous shift reached the surge limit in the direction of smaller mass flows.
Zu nennen ist in diesem Zusammenhang
die
Aufgabe der Erfindung ist es, eine akustisch optimierte, mit einem guten Wirkungsgrad arbeitende Drallerzeugungseinrichtung bereitzustellen, welche sehr einfach aufgebaut ist und so besonders günstig herzustellen und zu montieren ist und welche auf einfache Weise ohne maßgebliche Änderungen angrenzender Komponenten in ein bestehendes System integrierbar ist.The object of the invention is a acoustically optimized swirl generator with good efficiency to provide, which is very simple and so special cheap to manufacture and is to be assembled and which in a simple manner without significant changes adjacent components can be integrated into an existing system is.
Die Lösung der Aufgabe erfolgt mit einer Drallerzeugungseinrichtung mit den Merkmalen des Anspruchs 1, wobei gemäß der zu Grunde liegenden Idee ein in den stutzenartig ausgebildeten Ladelufteinlass des Verdichtergehäuses und/oder in die Ladeluftsaugleitung einschiebbarer, dem Verdichterlaufrad vorgeordneter Drallerzeuger vorgesehen ist.The task is solved with a swirl generating device with the features of the claim 1, according to the to The basic idea is a charge-air intake that is designed like a nozzle of the compressor housing and / or insertable into the charge air suction line, the compressor impeller upstream swirl generator is provided.
Besonders zu bevorzugende Ausgestaltungen und Weiterbildungen der Erfindung sind Gegenstand der Unteransprüche.Particularly preferred configurations and developments of the invention are the subject of the dependent claims.
Einem besonders bevorzugten Ausführungsbeispiels zufolge ist das Verdichtergehäuse ladeluftsaugseitig zur Verbindung mit der Ladeluftsaugleitung stutzenartig ausgebildet und der Drallerzeuger im Verbindungsbereich zwischen Ladeluftsaugleitung und Verdichtergehäuse angeordnet. Zweckmäßigerweise sind dabei Mittel zur akustischen Entkoppelung der Ladeluftsaugleitung und/oder des Drallerzeugers vom Verdichtergehäuse – wie eine elastische Dichtung zwischen Ladeluftsaugleitung und/oder Drallerzeuger einerseits und Verdichtergehäuse andererseits – vorgesehen.A particularly preferred embodiment according to the compressor casing on the charge air suction side for connection to the charge air suction line, nozzle-like trained and the swirl generator in the connection area between Charge air suction line and compressor housing arranged. Conveniently, are means for acoustic decoupling of the charge air suction line and / or the swirl generator from the compressor housing - like an elastic seal between charge air suction line and / or swirl generator on the one hand and compressor housing on the other hand - provided.
Bevorzugt ist es, wenn der Drallerzeuger einen Befestigungsflansch sowohl zur radialen Festlegung innerhalb der Ladeluftsaugleitung oder des Verdichtergehäuses, wobei der radial äußere Rand des Flansches innenseitig an der Ladeluftsaugleitung oder dem Verdichtergehäuse anliegt, als auch zur axialen Festlegung zwischen Ladeluftsaugleitung und Verdichtergehäuse, wobei die Ladeluftsaugleitung einen mit dem Einlassstutzenende des Verdichtergehäuses korrespondierenden axialgerichteten Absatz aufweist, umfasst.It is preferred if the swirl generator a mounting flange for both radial fixing within the charge air suction line or the compressor housing, the radially outer edge of the flange rests on the inside of the charge air suction line or the compressor housing, as well as for the axial fixing between the charge air suction line and Compressor housing, wherein the charge air suction line one with the inlet end of the compressor housing has corresponding axially directed paragraph.
Bevorzugterweise ist der Drallerzeuger rohrabschnittsförmig mit innenliegenden Leitschaufeln ausgebildet, die Leitschaufeln sind starr angeordnet, wobei gemäß eines ebenfalls bevorzugten Ausführungsbeispiels die Leitschaufeln verstell- und/oder verformbar sind, so dass eine Anpassung entsprechend dem Massedurchsatz erfolgen kann.The swirl generator is preferred tube-shaped section formed with internal guide vanes, the guide vanes are rigidly arranged, according to one also preferred embodiment the guide vanes are adjustable and / or deformable, so that a Adjustment can take place according to the mass throughput.
Sehr zweckmäßig ist es weiterhin in Hinblick auf eine mögliche Resonanzbildung an den Verdichterradschaufeln, wenn der Drallerzeuger eine ungerade Anzahl Leitschaufeln aufweist, so dass einer unerwünschten Resonanzbildung vorgebeugt ist.It is still very useful with regard to a possible Resonance formation on the compressor wheel blades when the swirl generator has an odd number of vanes, making an undesirable one Prevention of resonance is prevented.
