Abstract
Description
Die vorliegende Erfindung betrifft ganz allgemein eine Luftansaugvorrichtung eines Verbrennungsmotors in einem Kraftfahrzeug, und betrifft insbesondere eine Filtereinrichtung für einen Ansauggeräuschdämpfer eines Kraftfahrzeuges.The The present invention relates generally to an air intake device an internal combustion engine in a motor vehicle, and in particular relates a filter device for an intake silencer of a Motor vehicle.
Im
Stand der Technik ist es beispielsweise aus der
Aus
der
Aufgrund von Emissionsvorschriften besitzen Luftansaugvorrichtungen, die auch als Ansauggeräuschdämpfer bezeichnet werden, ein zweites Filterelement – neben dem Luftfilter – um verdunstende Brennstoffdämpfe bzw. Kohlenwasserstoffe aufzunehmen und zu absorbieren.by virtue of Emission regulations have air intake devices that Also referred to as intake silencer , a second filter element - next to the air filter - to evaporating fuel vapors or hydrocarbons absorb and absorb.
Die bekannten ebenen, plattenförmigen Filterelemente bieten jedoch keinen besonders großen Spielraum bei der räumlichen Gestaltung des Ansauggeräuschdämpfers. Ganz im Gegenteil, durch die plattenförmige Ausgestaltung der Aktivkohlefilterelemente nach dem Stand der Technik werden kompakte bzw. optimierte Bauweisen verhindert. Eine flexible Formgebung des Ansauggeräuschdämpfers wird dadurch verhindert.The known levels, plate-shaped However, filter elements do not offer much room for maneuver at the spatial Design of the intake silencer. On the contrary, by the plate-shaped design of the activated carbon filter elements According to the prior art are compact or optimized designs prevented. A flexible design of the intake silencer is thereby prevented.
Da Bauraum im Motorraum von modernen Kraftfahrzeugen immer knapp ist, besteht ein Bedarf, auch Ansauggeräuschdämpfer einer flexibleren Formgebung zu unterwerten.There Space in the engine compartment of modern motor vehicles is always scarce, There is a need, also Ansauggeräuschdämpfer a more flexible design to be understated.
Es ist daher die Aufgabe der vorliegenden Erfindung, eine Filtervorrichtung für einen Ansauggeräuschdämpfer derart zu schaffen, dass eine optimierte Formgebung des Ansauggeräuschdämpfers ermöglicht ist.It Therefore, the object of the present invention is a filter device for one Intake silencer in such a way to provide that an optimized design of the Ansauggeräuschdämpfers is possible.
Die Erfindung weist zur Lösung dieser Aufgabe die im Anspruch 1 angegebenen Merkmale auf. Vorteilhafte Ausgestaltungen hiervon sind in den weiteren Ansprüchen angegeben.The Invention points to the solution this object to the features specified in claim 1. advantageous Embodiments thereof are specified in the further claims.
Es ist dabei ein Ziel der vorliegenden Erfindung, die oben erwähnte Formgebungsfreiheit derart zu nutzen, dass das Ansauggeräuschdämpfervolumen vergrößert werden kann, wodurch die Geräuschdämpfung und die Motorleistung verbessert werden können.It is an object of the present invention, the above-mentioned freedom of design to be used such that the Ansauggeräuschdämpfervolumen be increased can, thereby reducing the noise and the engine power can be improved.
Gelöst wird die oben genannte Aufgabe durch eine Filtervorrichtung für einen Ansauggeräuschdämpfer, mit einem Gehäuse, einem Luftfilterelement, welches im Gehäuse austauschbar angeordnet ist, und ein zweites Filterelement, welches reinluftseitig des Luftfilterelements gehäusefest angeordnet ist, wobei die beiden Luftfilterelemente derart angeordnet sind, dass das zweite Filterelement innerhalb des Raumes, welchen das Luftfilterelement definiert, angeordnet ist.Is solved the above object by a filter device for a Intake silencer, with a housing, an air filter element which is arranged interchangeable in the housing is, and a second filter element which clean air side of the air filter element fixed to the housing is arranged, wherein the two air filter elements arranged such are that the second filter element within the room, which the air filter element defined, is arranged.
Durch die erfindungsgemäße Ausgestaltung der Filtervorrichtung ist eine flexible Gestaltung der Filtervorrichtung bzw. des Gehäuses möglich, insbesondere können der Lufteintritt und der Luftaustritt individuell an die Gegebenheiten im Motorraum eines spezifischen Kraftfahrzeuges angepaßt werden.By the embodiment of the invention Filter device is a flexible design of the filter device or of the housing possible, in particular can the air inlet and the air outlet individually to the conditions be adapted in the engine compartment of a specific motor vehicle.
Für verschiedene Zielmärkte können einfach unterschiedliche Varianten eines Ansauggeräuschdämpfers realisiert werden.For different target markets can simply realized different variants of Ansauggeräuschdämpfers become.
Die vorstehende Aufgabe, die Merkmale und Vorteile nach der vorliegenden Erfindung können unter Berücksichtigung der folgenden, detaillierten Beschreibung der bevorzugten Ausführungsformen der vorliegenden Erfindung und unter Bezugnahme auf die zugehörigen Zeichnungen besser verstanden werden.The above object, the features and advantages of the present invention Invention can considering the following detailed description of the preferred embodiments of the present invention and with reference to the accompanying drawings to be better understood.
