Abstract
Description
Die Erfindung betrifft einen Axialzyklon als Ölnebelabscheider eines Kraftfahrzeug-Verbrennungsmotors nach dem Oberbegriff des Patentanspruchs 1.The The invention relates to an axial cyclone as an oil mist separator of a motor vehicle internal combustion engine according to the preamble of claim 1.
Derartige
Axialzyklone sind in vielfachen Ausführungen bereits bekannt und
zwar beispielsweise aus
Darüber hinaus
ist es auch noch bekannt, derartige Axialzyklone in die Kurbelwelle
eines Verbrennungsmotors (
Bei diesen Integrationslösungen sind die zu treffenden Integrationsmaßnahmen teilweise recht aufwändig. Darüber hinaus ist eine Integration in drehende Motorelemente nur dann möglich, wenn diese bereits hohl rohrförmig ausgenommen sind oder solche Ausnehmungen einfach in diesen vornehmbar sind.at these integration solutions In some cases, the integration measures to be taken are quite complex. Furthermore is integration in rotating motor elements only possible if this already hollow tubular are excluded or such recesses are simply vornehmbar in this.
Die Erfindung beschäftigt sich mit dem Problem, einen Ölnebelabscheider eines Kraftfahrzeug-Verbrennungsmotors in einer möglichst einfachen Form bei einer gleichzeitig guten Effizienz als einen gattungsgemäßen Axialzyklon auszubilden.The Invention busy with the problem, an oil mist separator a motor vehicle internal combustion engine in a possible simple form with a simultaneously good efficiency as one generic axial cyclone train.
Gelöst wird dieses Problem in erster Linie bereits durch eine Ausbildung eines solchen Axialzyklons nach dem kennzeichnenden Merkmal des Patentanspruchs 1.Is solved this problem already in the first place by an education of a such Axialzyklons according to the characterizing feature of the claim 1.
Vorteilhafte und zweckmäßige Ausgestaltungen der Erfindung sind Gegenstand der Unteransprüche.advantageous and appropriate embodiments The invention are the subject of the dependent claims.
Die Erfindung beruht auf dem allgemeinen Gedanken, einen gattungsgemäßen Axialzyklon völlig integrationsfrei von anderen Funktionselementen in bzw. an dem Verbrennungsmotor in einem Bereich vorzusehen, der hierfür ausreichend Platz bietet. Dieser Bereich kann grundsätzlich innerhalb oder außerhalb des Motorgehäuses liegen. Innerhalb des Motorgehäuses bedeutet im vorgenannten Sinne innerhalb eines von den Kurbelraumgasen, in dem der Ölnebel vorliegt, beaufschlagten Raum, der nach außen gedichtet ist.The The invention is based on the general idea of a generic axial cyclone completely integration-free of other functional elements in or on the internal combustion engine to be provided in an area which offers sufficient space for this purpose. This area can basically inside or outside of the motor housing lie. Inside the motor housing in the aforementioned sense means within one of the crankcase gases, in which the oil mist present, acted space, which is sealed to the outside.
Für sämtliche Ausführungsarten unabhängig davon, ob ein Einsatz innerhalb oder außerhalb des Motorgehäuses erfolgt, besteht der Axialzyklon im wesentlichen lediglich aus einem rohrförmigen Abscheidegehäuse, das im einfachsten Fall ein einfaches Rohr ist, das möglichst reibungsarm innerhalb des Motors ortsfest gelagert ist.For all embodiments independently of, whether an insert is inside or outside the motor housing, the axial cyclone consists essentially only of a tubular separator housing, the in the simplest case a simple tube is that possible low friction within the engine is stored stationary.
Der Antrieb des rohrförmigen Abscheidegehäuses, mit dem dieses in Rotation für einen Abscheidebetrieb gesetzt werden kann, kann sowohl durch einen eigenständigen, beispielsweise als Elektromotor ausgebildeten Antrieb oder durch die Mitbenutzung eines Antriebes für andere Funktionselemente erfolgen.Of the Drive of the tubular separator housing, with this in rotation for can be set to a separating operation, both by a independent, for example, designed as an electric motor drive or by the shared use of a drive for other functional elements respectively.
Bei einem Einsatz eines separaten Elektromotors kann das rohrförmige Abscheidegehäuse Bestandteil des Elektromotors sein, in dem dieses den Rotor eines solchen Motors bildet.at a use of a separate electric motor, the tubular separator housing part of the electric motor in which this is the rotor of such an engine forms.
Möglich ist es auch, dass das rohrförmige Abscheidegehäuse ausschließlich durch den dieses Gehäuse durchströmenden Ölnebelstrom angetrieben wird. Der Antrieb erfolgt dabei durch den innerhalb des rohrförmigen Abscheidegehäuses angebrachten Drallerzeuger, der die Strömungsenergie des Ölnebelstromes in Rotationsenergie umsetzt.Is possible it also, that the tubular separator housing exclusively by this case flowing oil mist stream is driven. The drive is done by the inside of the tubular separator housing attached swirl generator, the flow energy of the oil mist stream converts into rotational energy.
Bei einem Einsatz des erfindungsgemäßen Axialzyklons innerhalb eines Motorgehäuses kann dessen stromabseitiges Ende für einen Gasrückstrom, das heißt für einen Rückstrom von von Öltröpfchen befreiter Kurbelgehäuseluft ausgebildet sein. Näheres hierzu kann der nachfolgenden Beschreibung eines entsprechenden Ausführungsbeispieles entnommen werden.at an insert of the axial cyclone according to the invention inside a motor housing can its downstream end for a gas backflow, this means for one reverse current of oil droplets freed crankcase air be educated. For details, For this purpose, the following description of a corresponding Example taken become.
Wiederum bei einem Einsatz des Axialzyklons innerhalb eines Motorgehäuses kann einströmungsseitig eine Vorabscheideeinrichtung vorgesehen sein, wie sie im Einzelnen ebenfalls einem der beiden nachfolgend beschriebenen Ausführungsbeispielen entnommen werden kann.In turn when using the Axialzyklons within a motor housing einströmungsseitig a Vorabscheideeinrichtung be provided as they are in detail also one of the two embodiments described below can be removed.
Insbesondere auch bei einem Einsatz eines Axialzyklons außerhalb eines Motorgehäuses können zu- und abströmseitig Dichtungen vorgesehen werden, die lediglich in der Form einer Spaltdichtung dichten, das heißt nicht absolut dicht sind. Ermöglicht wird dies dadurch, dass der Ölnebelstrom mit Unterdruck durch das Abscheidegehäuse gesaugt wird und zwar zum Luftansaugstutzen des Verbrennungsmotors hin.Especially even when using an axial cyclone outside of a motor housing, additional and downstream Seals are provided which only seal in the form of a gap seal, this means not absolutely tight. This is possible This is due to the fact that the oil mist stream is sucked through the separator housing with negative pressure and that to Air intake of the engine out.
Das Druckgefälle innerhalb des Abscheidegehäuses kann gegebenenfalls durch den Einsatz einer Pumpe erhöht werden.The pressure drop within the separator housing may optionally be increased by the use of a pump.
Vorteilhafte, nachstehend näher erläuterte Ausführungsbeispiele sind in der Zeichnung jeweils schematisch dargestellt.Advantageous, explained in more detail below Embodiments are shown schematically in the drawing.
