Aus dem US Patent 5,014,816 ist ein Ansaugsystem einer Brennkraftmaschine bekannt, bei dem ein Luftfiltergehäuse vorgesehen ist, welches ein Flachfilterelement aufnimmt. Oberhalb des Filterelements befinden sich mehrere Kammern, die sich nach außen erstrecken und als Lambda/4-Rohr aufgebaut sind. Durch diese Kammern wird eine Geräuschreduktion in bestimmten Frequenzen erzielt. Die Kammern benötigen einen relativ großen Bauraum, erstrecken sich in die Peripherie des Luftfiltersystems und sind sehr aufwendig bei der Fertigung.From US patent 5,014,816 an intake system of an internal combustion engine is known, in which an air filter housing is provided which receives a flat filter element. Above the filter element are several chambers that face outward extend and are constructed as a lambda / 4-tube. Through these chambers is a noise reduction achieved in certain frequencies. The chambers need a relative large space, extend into the periphery of the air filter system and are very consuming in the production.
Es ist ferner aus dem US Patent 4,524,494 ein Geräuschreduktionssystem bekannt, auch hier wird ein Gehäuse in Form eines Helmholtz-Resonators verwendet, welches zwischen zwei Luftansaugstutzen angeordnet sind. Dieses Gehäuse erstreckt sich über einen größeren Bauraum hinaus. Neben dem Gehäuse sind weitere Elemente wie zum Beispiel Lambda/4-Rohr oder Luftführungsrohre vorgesehen. Der Nachteil dieser Einrichtung liegt in dem umfangreichen Bauraum, der für die Verbesserung der akustischen Eigenschaften benötigt wird.It is also known from US Patent 4,524,494 a noise reduction system, also Here, a housing in the form of a Helmholtz resonator is used, which between two air intake are arranged. This housing extends over a larger one Space beyond. In addition to the housing are other elements such as Lambda / 4-pipe or air ducts provided. The disadvantage of this device is in the vast amount of space needed for the improvement of the acoustic properties is needed.
Der Erfindung liegt die Aufgabe zugrunde, die genannten Nachteile zu vermeiden und ein Ansaugsystem für eine Brennkraftmaschine zu schaffen, welches kostengünstig und platzsparend aufgebaut werden kann. Diese Aufgabe wird ausgehend von dem Oberbegriff des unabhängigen Anspruchs 1 durch dessen Kennzeichnungen/Merkmale gelöst.

This task is based on the generic term of independent claim 1 solved by its markings / features.
Der wesentliche Vorteil der Erfindung liegt darin, dass Elemente wie Nebenschlussresonator oder Lambda/4-Rohr, welche üblicherweise als aufwändige Zusatzteile an einem Ansaugsystem einer Brennkraftmaschine adaptiert werden mussten, nun mehr in das Filtergehäuse integriert werden können.The essential advantage of the invention is that elements such as shunt resonator or lambda / 4-tube, which usually as complex additional parts to a Intake system of an internal combustion engine had to be adapted, now more in the Filter housing can be integrated.
Durch eine Luftströmungsberechnung kann ein Filtergehäuse in Bereiche eingeteilt werden, in denen eine große bzw. keine Luftbewegung stattfindet. Die Gebiete in denen keine Luftbewegung statt findet sind Volumina, welche als Nebenschlussresonatoren genutzt werden können. Der Vorteil besteht darin, dass diese Nebenschlussresonatoren bei der Herstellung des Systems ohne großen Aufwand mitentstehen. Es ist hier im Minimalfall lediglich eine zusätzliche Trennwand vorzusehen. Ferner sind diese Nebenschlussresonatoren oder Bauteile nicht von außen sichtbar und stören deshalb nicht die äußerliche Gestaltung eines Ansaugsystems.By an air flow calculation, a filter housing can be divided into areas, in which a large or no air movement takes place. The areas where no Air movement takes place are volumes which are used as shunt resonators can be. The advantage is that these shunt resonators at the creation of the system without much effort. It is here in the minimum case to provide only an additional partition. Furthermore, these shunt resonators or components are not visible from the outside and therefore do not disturb the external Design of an intake system.
Gemäß einer Ausgestaltung der Erfindung kann der Nebenschlussresonator sowohl auf der Rohluftseite als auch auf der Reinluftseite des Luftfiltergehäuses angeordnet werden. In beiden Bereichen befindet sich unter Umständen ein Totraumvolumen, welches nutzbar gemacht wird.According to one embodiment of the invention, the shunt resonator on both the raw air side and be arranged on the clean air side of the air filter housing. In both areas there may be a dead space volume which can be used is done.
In einer weiteren Ausgestaltung wird ein Nebenschlussresonator von einer Außenwand des Luftfiltergehäuses gebildet, eine benachbart angeordnete Trennwand schließt das Volumen des Resonators gegen das weitere Gehäusevolumen ab.In a further embodiment, a shunt resonator of an outer wall formed of the air filter housing, an adjacently arranged partition closes the Volume of the resonator against the other housing volume from.
In einer konstruktiven Ausgestaltung der Erfindung ist bei einer V-förmig angeordneten Brennkraftmaschine bei welcher zwei Luftfilter vorgesehen sind, innerhalb der Luftfiltergehäuse zwei Nebenschlussresonatoren angeordnet. In vielen Fällen wird die äußere Kontur eines Ansaugsystems bzw. eines Luftfiltergehäuses durch die Form der Brennkraftmaschine bestimmt, dieses führt zwangsweise zu Hohlräumen innerhalb des Luftfiltergehäuses, die erfindungsgemäß genutzt werden können. Weiterbildungsgemäß können die Hohlräume bzw. Wände mit zusätzlichen Stegen oder weiteren Hohlraumelementen versehen sein, dies kann im Rahmen einer akustischen Optimierung zu einer Verbesserung des Resonatorverhaltens führen.In a structural embodiment of the invention is arranged at a V-shaped Internal combustion engine in which two air filters are provided, within the air filter housing two shunt resonators arranged. In many cases, the outer becomes Contour of an intake system or an air filter housing by the shape of the internal combustion engine determined, this inevitably leads to cavities within the air filter housing, which can be used according to the invention. Further education can the cavities or walls with additional webs or other cavity elements This can be an improvement in the context of an acoustic optimization the Resonatorverhaltens lead.
Eine weitere Ausgestaltung sieht vor, ein Staubaustragsventil oder Wasseraustragsventil innerhalb des Nebenschlussresonators anzuordnen. Dies hat den Vorteil, dass die Austragung ohne Verwirbelung der auszutragenden Bestandteile erfolgen kann. In einer Weiterbildung der Erfindung ist vorgesehen den Resonator als Plattenresonator zu gestalten.Another embodiment provides a dust discharge valve or water discharge valve within the shunt resonator. This has the advantage of being the host can be done without turbulence of the components to be discharged. In a further education The invention provides for the resonator to be designed as a plate resonator.
Bei einem Plattenresonator handelt es sich um einen Hohlraum zwischen zwei Platten, wobei die wirksame Frequenz über den Abstand der Platten zur Wand die Anzahl und den Durchmesser der Öffnungen einstellbar ist. Eine weitere Verbesserung der Dämpfung kann über zusätzliches Absorbermaterial erzielt werden.A plate resonator is a cavity between two plates, where the effective frequency over the distance of the plates to the wall the number and the diameter of the openings is adjustable. Another improvement in damping can be achieved via additional absorber material.

Das in Figur 1 gezeigte Luftfiltergehäuse ist konzipiert als Abdeckung für eine V-förmig
angeordnete Brennkraftmaschine. Es besitzt eine äußere Kontur 10, die das Gesamtgehäuse
umschließt. Die Draufsicht zeigt innerhalb der Kontur 10 angeordnete Plattenfilterelemente
11; 12 unterhalb dieser Plattenfilterelemente befindet sich der jeweilige Rohlufteinlass.
Die einströmende Luft wird durch die Plattenfilterelemente hindurchgeführt,
gereinigt und strömt in die Reinluftbereiche 13; 14. Von dort wird die Luft jeweils den Zylinderbänken
der Brennkraftmaschine zugeführt. Unmittelbar benachbart zu dem jeweiligen
Plattenfilterelement 11; 12 befindet sich ein Bereich 15; 16 in dem wenig oder nur
eine geringe Luftströmung stattfindet. Dieser Gehäusebereich ist bedingt durch die äußere
Kontur 10, die wiederum aus Designgründen erforderlich ist. Zur Nutzung dieses Bereichs
ist jeweils eine Trennwand 17; 18 vorgesehen, diese verläuft annäherungsweise
parallel zu der Innenkontur 19; 20 und ist im Bereich 21; 22 an dieser Innenkontur befestigt.
Auf der gegenüberliegenden Seite ist die Trennwand abgekröpft und bildet mit der
Innenkontur 19; 20 jeweils einen akustischen Hals 23; 24. Damit ein wirksames Nebenschlussresonatorvolumen
entsteht ist die Trennwand 17; 18 nicht nur mit der Innenkontur
19; 20 sondern auch mit wenigstens zwei weiteren Gehäusewänden verbunden.
Der akustische Hals 23; 24 stellt die Verbindung zu dem jeweils benachbart liegenden
Reinluftbereich 13; 14 dar.The air filter housing shown in Figure 1 is designed as a cover for a V-shaped
arranged internal combustion engine. It has an
Figur 2 zeigt in einer Detailansicht zwei weitere Varianten einer Trennwand 25; 26; gleiche
Teile sind mit gleichen Bezugszeichen versehen. Der Hohlraum 27 ist ohne die Bildung
eines akustischen Halses gestaltet der Hohlraum 28 weist die Besonderheit auf,
dass sich darin Stege 29; 30; 31; 32; 33 befinden, welche die akustischen Eigenschaften
des Nebenschlussresonators verbessern. Diese Stege können sich über die gesamte
Trennwandhöhe erstrecken.FIG. 2 shows in a detailed view two further variants of a
Figur 3 zeigt ein System, welches ein Gehäuse 34 aufweist, dieses ist mit einem Deckel
35 verschließbar. Innerhalb des Gehäuses befindet sich ein Filterelement 36 das als Plattenfilterelement
aufgebaut ist und aus einem zick-zack-förmig gefalteten Filterpapier besteht.
Die umlaufende Dichtung 37 des Filterelements dichtet gleichzeitig den Deckel 35
auf dem Gehäuse 34. An dem Gehäuse 34 befindet sich ein Rohlufteintritt 38. An dem
Deckel 35 befindet sich der Reinluftaustritt 39. Die zu reinigende Luft strömt durch den
Rohlufteintritt 38 ein, durchströmt das Filterelement und wird gereinigt über den Austritt
39 einer hier nicht dargestellten Brennkraftmaschine zugeführt. Das Gehäuse 34 hat eine
nach unten gezogene Form mit einer Topf-förmigen Ausgestaltung 40 an welcher sich im
Bodenbereich 41 ein Staubaustragsventil 42 befindet. Parallel zu dem Boden 41 ist eine
Trennwand 43 angeordnet. Die Trennwand weist wenigstens eine Öffnung 44 zu dem
Rohluftraum des Gehäuses 34 auf, diese Öffnung ist derart gestaltet, dass sowohl der mit
der Rohluft eingeleitete Staub dem Staubaustragsventil zugeführt werden kann, als auch
eine akustische Eigenschaft des durch die Trennwand gebildeten Nebenschlussresonators
bewirkt wird. In einer weiteren Variante die hier lediglich gestrichelt dargestellt wird,
wird die Trennwand 45 so angeordnet, dass sie mit der rechtsseitigen Wand des Gehäuses
34 einen Hohlraum 46 als Nebenschlussresonator bildet. Selbstverständlich besteht
auch die Möglichkeit nicht eine Trennwand anzuordnen, sondern ein Lambda/4-Rohr 50,
in dem Bereich des Filtergehäuses vorzusehen, welcher nicht von der Luft durchströmt
wird.Figure 3 shows a system which has a
Ein Lambda/4Rohr 50 sollte zweckmäßigerweise in der Nähe des Reinluftaustritts seine Öffnungen besitzen. An dieser Stelle besitzt dieses akustische Mittel die beste Wirksamkeit.A lambda / 4 pipe should suitably be near the clean air outlet its Possess openings. At this point, this acoustic means has the best effectiveness.
