Abstract
Description
Die Erfindung betrifft ein Ansaugsystem, insbesondere zur Verwendung als Ansaugkanal einer Brennkraftmaschine, nach der Gattung des Patentanspruches 1 (siehe US-A-444 9607 oder US-A-3712416).The invention relates to an intake system, in particular for use as an intake passage of an internal combustion engine, according to the preamble of claim 1 (see US-A-444 9607 or US-A-3712416).
Ansaugsysteme für Brennkraftmaschinen werden insbesondere im Bereich des Saugrohres mit Nebenschlußresonatoren versehen, um eine Dämpfung des Ansauggeräusches zu erreichen. Im einfachsten Fall bestehen diese Nebenschlußresonatoren aus eine Resonatorraum und einem Resonatorhals der den Resonatorraum mit dem Saugrohr verbindet. Diese Grundform des Nebenschlußresonators kann in Abhängigkeit vom jeweiligen Anwendungsfall variiert werden. Es sind mehrere Hälse denkbar die bei unterschiedlicher Länge eine Dämpfung von Ansauggeräuschen unterschiedlicher Frequenzen ermöglichen. Der Resonatorraum kann nahezu beliebige Formen besitzen.Intake systems for internal combustion engines are provided in particular in the region of the intake manifold with shunt resonators in order to achieve a damping of the intake noise. In the simplest case, these shunt resonators consist of a resonator chamber and a resonator neck which connects the resonator chamber to the suction tube. This basic form of shunt resonator can be varied depending on the particular application. There are several necks conceivable that allow for different lengths attenuation of intake noise of different frequencies. The resonator space can have almost any shape.
Nachteilig an der Verwendung von Nebenschlußresonatoren ist deren Platzbedarf im Bereich des Saugrohres. Dieser muß im Motorraum vorgesehen werden, was durch die engen Platzverhältnisse im Motorraum erschwert wird. Ein Ansatz zur Lösung des Problems ist der z. B. DE 3842248 A1 zu entnehmen. Es wird ein Resonator vorgeschlagen, der in das Gehäuse des Ansaugsystems integriert ist. Dadurch wird die Nutzung des in dem Gehäuse anfallenden Totvolumens als Resonatorraum möglich. Es muß daher kein zusätzlicher Einbauraum im Motorraum zur Verfügung gestellt werden.A disadvantage of the use of shunt resonators whose space requirement in the region of the suction pipe. This must be provided in the engine compartment, which is complicated by the tight space in the engine compartment. One approach to solving the problem is the z. For example, see DE 3842248 A1. It is proposed a resonator, which is integrated in the housing of the intake system. This makes it possible to use the dead volume accumulating in the housing as a resonator chamber. There must therefore be no additional installation space in the engine compartment available.
Der oben beschriebene Resonatorraum muß jedoch konstruktiv schon bei der Gestaltung des Saugrohrgehäuses beachtet werden. Nachteilig dabei ist, daß der beschriebene Resonator nicht nachträglich zur Verbesserung der Akustik eines Saugrohres verwendet werden kann, wenn die Ergebnisse hinsichtlich der Ansauggeräusche des Saugrohres unbefriedigend sind. In einer solchen Situation ist häufig auch im Motorraum kein zusätzlicher Platz für einen Nebenschlußresonator vorhanden, da die Entwicklung des fraglichen Fahrzeugs fast abgeschlossen ist. Dadurch können im Saugrohrbereich teure neue Konstruktion notwendig werden.However, the resonator space described above must be considered structurally already in the design of the intake manifold. The disadvantage here is that the resonator described can not be used subsequently to improve the acoustics of a suction tube, if the results are unsatisfactory with respect to the intake noise of the intake manifold. In such a situation, there is often no additional space for a shunt resonator even in the engine compartment since the development of the vehicle in question is almost completed. This can be necessary expensive new construction in Saugrohrbereich.
Aufgabe der Erfindung ist es einen Helmholzresonator zu schaffen der einen geringen Bauraum für sich beansprucht und auch nachträglich in eine bereits bestehende Saugrohrkonstruktion eingefügt werden kann. Dabei sollen entweder spezielle Frequenzen des Ansauggeräusches gedämpft werden oder eine Breitbanddämpfung erzielt werden.The object of the invention is to provide a Helmholzresonator claimed a small space for themselves and can also be added later in an existing Saugrohrkonstruktion. In this case, either special frequencies of the intake noise to be damped or broadband attenuation can be achieved.
Erfindungsgemäß wird die Aufgabe dadurch gelöst, daß eine Innenstruktur in den Innenraum der Saugrohrs eingelegt und dort befestigt wird. Diese Innenstruktur bildet zusammen mit den Wänden des Saugrohres einen Resonatorraum, der mindestens eine Öffnung zum Saugrohrvolumen hin besitzen muß. Eine solche Innenstruktur benötigt keinen zusätzlichen Bauraum im Motorraum. Vorteilhaft ist weiterhin die Möglichkeit eines nachträglichen Einbaus. Dies ist vor allen Dingen bei Saugrohren einfach zu realisieren, die in Mehrschalentechnik gefertigt werden. Ebenso kann eine solche Innenstruktur jedoch durch die Einlaß- bzw. Auslaßöffnungen des Saugrohres eingebracht werden. Dabei muß die Gestalt des Saugrohres gar nicht oder nur unwesentlich verändert werden. Würde die Innenstruktur z. B. eingeklebt, muß diese lediglich an einen bestimmten Konturbereich des Saugrohres angepaßt werden. Vorteilhafterweise kann die Innenstruktur derart gestaltet sein, daß sie nach Montage im Saugrohr mehrere Resonatorräume unterschiedlichen Volumens erzeugt. Durch diese Maßnahme können unterschiedliche Frequenzen im Ansaugbereich schwerpunktmäßig gedämpft werden.According to the invention the object is achieved in that an inner structure is inserted into the interior of the suction tube and fastened there. This internal structure, together with the walls of the suction pipe, forms a resonator space which must have at least one opening to the intake manifold volume. Such an internal structure requires no additional space in the engine compartment. A further advantage is the possibility of retrofitting. This is especially easy to implement with suction tubes, which are manufactured in multi-shell technology. Likewise, however, such an internal structure can be introduced through the inlet or outlet openings of the suction tube. The shape of the suction tube does not have to be changed at all or only insignificantly. Would the internal structure z. B. glued, it must be adapted only to a certain contour region of the suction tube. Advantageously, the inner structure may be designed such that it generates a plurality of resonator chambers of different volume after mounting in the intake manifold. By this measure, different frequencies in the intake can be mainly attenuated.
Eine sinnvolle Variante der Erfindung sieht die Montage der Innenstruktur im Innenraum des Saugrohrs vor. Dieser ist vor den Ansaugkanälen zu den Zylindern angeordnet. Daher wirkt die Geräuschdämpfung auf alle Ansaugkanäle des Saugrohrs.A useful variant of the invention provides for the assembly of the inner structure in the interior of the suction tube. This is arranged in front of the intake ducts to the cylinders. Therefore, the noise damping acts on all intake ports of the intake manifold.
Nach einer sinnvollen Ausgestaltung der Innenstruktur ist diese aus einem flachen Bauteil, z. B. einem Lochblech, und Abstandhaltern aufgebaut. Der Resonatorraum entsteht demnach zwischen dem Lochblech und der Saugrohrwand. Vorteilhaft ist dabei, daß die Innenstruktur aus einfachen Halbzeugen herstellbar ist. Dies führt zu einer Erhöhung der Wirtschaftlichkeit bei Kleinserien, z. B. im Tuningbereich.After a meaningful design of the inner structure of these is a flat component, for. B. a perforated plate, and spacers constructed. The resonator space thus arises between the perforated plate and the Saugrohrwand. It is advantageous that the inner structure of simple semi-finished products can be produced. This leads to an increase in cost-effectiveness in small series, z. In the tuning area.
Eine alternative Variante der Innenstruktur sieht deren Gestaltung als Einlegeteil vor. Dieses kann einteilig ausgeführt sein mit positiven Wirkung auf die Wirtschaftlichkeit in der Großserie.An alternative variant of the internal structure provides for their design as an insert. This can be carried out in one piece with a positive effect on the economy in mass production.
Einer weiteren Ausgestaltung der Erfindung gemäß kann die Innenstruktur Bereiche unterschiedlicher Wandstärke aufweisen. Sieht man in einer Innenstruktur mehrere Öffnungen vor, so ergeben sich dadurch unterschiedliche Halslängen für den Nebenschlußresonator. Der positive Effekt dieser Maßnahme ist eine Breitbanddämpfung des Ansauggeräusches.According to a further embodiment of the invention, the inner structure may have regions of different wall thickness. If one sees several openings in an inner structure, this results in different neck lengths for the shunt resonator. The positive effect of this measure is a broadband attenuation of the intake noise.
Unter der Voraussetzung, daß die Innenstruktur sowie das Saugrohr aus demselben Material bestehen, kann die Innenstruktur auch in das Saugrohr eingeschweißt werden. Dies gilt insbesondere für Kunststoffsaugrohre, ist jedoch auch für metallische Saugrohre denkbar. Ein Kunststoffeiniegeteil kann insbesondere durch das Ultraschallschweißverfahren gefügt werden. Es sind allerdings auch andere Schweißverfahren, z. B. das Reibschweißverfahren, möglich.Provided that the inner structure and the suction tube made of the same material, the inner structure can also be welded into the intake manifold. This is especially true for plastic suction, but is also conceivable for metallic suction pipes. A plastic entry part can in particular be joined by the ultrasonic welding process. However, there are other welding methods, eg. As the friction welding, possible.
