Abstract
Die Erfindung betrifft einen Luftfilter für eine Brennkraftmaschine, mit einem Gehäuse (2), in dem ein Luftfilterelement (8) angeordnet ist, welches zwischen einem Rohlufteinlass (10) in einer Rohluftschale (4) und einem Reinluftauslass (12) in einer Reinluftschale (6) angeordnet ist, sowie mit einer im Luftfiltergehäuse (2) vorgesehenen Öffnung (13), die durch ein luftdurchlässiges und feinmaschiges Gewebe oder durch ein dünnwandiges Schallelement abgedeckt ist. DOLLAR A Es wird vorgeschlagen, dass zur Optimierung der Schallabstrahlung auf der Reinluftseite ein Resonator (18) vorgesehen ist, der in Abhängigkeit vorgebbarer Motorparameter zu- bzw. abschaltbar ist.The invention relates to an air filter for an internal combustion engine, having a housing (2) in which an air filter element (8) is arranged between a unfiltered air inlet (10) in an empty air shell (4) and a clean air outlet (12) in a clean air shell (6 ) is arranged, and with an opening (13) provided in the air filter housing (2), which is covered by an air-permeable and fine mesh fabric or by a thin-walled sound element. DOLLAR A It is proposed that a resonator (18) is provided to optimize the sound radiation on the clean air side, which can be switched on or off in accordance with predefinable engine parameters.
Description
Die Erfindung betrifft einen Luftfilter für Brennkraftmaschine gemäß den Merkmalen des Oberbegriffs des Patentanspruchs 1.The The invention relates to an air filter for internal combustion engine according to the features of the preamble of claim 1.
Aus
der
Aufgabe der Erfindung ist es, die Wirkung der Schalleinrichtung noch besser an den jeweiligen Betriebszustand der Brennkraftmaschine anzupassen.task The invention is even better, the effect of the sound device to adapt to the respective operating state of the internal combustion engine.
Die Aufgabe wird durch die im Anspruch 1 angegebenen Merkmale gelöst.The The object is achieved by the features specified in claim 1.
Durch den zu- bzw. abschaltbaren Resonator kann der über die Gehäuseöffnung des Luftfilters abgestrahlte Schallpegel besser an den Betriebszustand der Brennkraftmaschine angepasst werden.By the resonator which can be switched on or off can be radiated via the housing opening of the air filter Sound level better at the operating condition of the internal combustion engine be adjusted.
Durch die in den Unteransprüchen aufgeführten Maßnahmen sind vorteilhafte Weiterbildungen und Ausgestaltungen der Erfindung möglich.By in the subclaims listed activities are advantageous developments and refinements of the invention possible.
Das durch den Resonator zu- bzw. abschaltbare Resonatorvolumen ist auf vorteilhafte Art und Weise in der Reinluftschale integriert und steht über einen Rohrleitungsabschnitt mit einer zum Ansaugtrakt der Brennkraftmaschine führenden Rohrleitung in Verbindung, wobei in dem Rohrleitungsabschnitt ein das Resonatorvolumen zu- bzw. abschaltbares Kontrollorgan angeordnet ist. Das Kontrollorgan ist dabei beispielsweise als unterdruckgesteuertes Klappenelement ausgebildet. Andere Ausführungsformen des Kontrollorgans, wie z. B. das Resonatorvolumen kontrollierende Ventile oder Membranen sind jedoch ebenfalls möglich.The Resonator volume which can be switched on or off by the resonator is open advantageous manner integrated in the clean air bowl and is about one Pipe section with a to the intake of the engine leading Pipe in communication, wherein in the pipe section a arranged the resonator volume on or switchable off control member is. The control element is, for example, as a vacuum-controlled flap element educated. Other embodiments the control body, such. B. the resonator volume controlling Valves or membranes are also possible.
Um zu vermeiden, dass über die im Luftfiltergehäuse angeordnete Öffnung Wasser, Schmutz oder dgl. in das Luftfiltergehäuse eindringen kann, wird vorgeschlagen, das Gewebe oder das Schallelement hydrophob zu beschichten.Around to avoid that over in the air filter housing arranged opening Water, dirt or the like can penetrate into the air filter housing, it is proposed to coat the fabric or the sound element hydrophobic.
Das Gewebe bzw. das Schallelement ist in einem Rahmen aufgenommen, der als Einsatzteil in der im Luftfiltergehäuse eingebrachten Gehäuseöffnung befestigt ist.The Tissue or the sound element is received in a frame, the attached as an insert in the housing opening introduced in the air filter housing is.
Der Resonator wird im unteren und mittleren Drehzahlbereich funktionslos geschaltet, um die Anregung der höheren Motorordnungen für die Schallübertragung mit einer diskreten Frequenz in den Innenraum zu nutzen. Im oberen Drehzahlbereich wird der Resonator aktiv geschaltet, um den Innengeräuschpegel abzusenken, da in diesem Bereich Resonanzerscheinungen durch die dominierenden Gaswechselordnungen besonders stark hervortreten.Of the Resonator is in the lower and middle speed range without function switched to the excitation of the higher engine orders for sound transmission to use with a discrete frequency in the interior. At the top Speed range, the resonator is activated to the internal noise level Lowering because in this area resonance phenomena by the Dominant gas exchange orders emerge particularly strong.
Die Erfindung wird nachfolgend anhand der Beschreibung und den Zeichnungen näher erläutert.The The invention will be described below with reference to the description and the drawings explained in more detail.
