Daimler-Benz Aktiengesellschaft Palm 9279/4 Daimler-Benz Aktiengesellschaft Palm 9279/4 Stuttgart-Üntertürkheim 3. Febr. 1972Stuttgart-Üntertürkheim February 3, 1972 Ansaugsystem für BrennkraftmaschinenIntake system for internal combustion engines

Die Erfindung bezieht sich auf ein Ansaugsystem für Brennkraftmaschinen, insbesondere Dieselmaschinen, bestehend aus einem mittels eines Verbindungs- ToixTts an das Motorsaugrohr angeechlossenen Aneauggeräuschdämpfer mit Luftfilter.The invention relates to an intake system for internal combustion engines, in particular diesel engines, consisting of an intake noise damper with an air filter connected to the engine intake manifold by means of a connection tool.

Bei derartigen Ansaugsystemen treten laute und unangenehme Motorbremsgeräusche auf, die durch eine lange schwingende Luftsäule im Ansaugsystem, die Bauteile wie Rohre und Schläuche zum ßdhwingen anregt, entstehen. Der Ansauggoräusch&ämpfer kann diese Geräusche nicht unterbinden, insbesondere da er weit vor der Brennkraftmaschine und dem Motorsaugrohr liegt. With such intake systems, loud and unpleasant engine braking noises occur caused by a long oscillating column of air in the intake system that stimulates components such as pipes and hoses to oscillate. The intake noise & muffler cannot suppress these noises, especially since it lies far in front of the internal combustion engine and the engine intake manifold.

Der Erfindung liegt die Aufgabe zugrunde, das Ansaugsystem so auszubilden, daß die Motorbremsgeräusche s.n ihrer Stärke erheblich gemindert werden.The invention is based on the object of designing the intake system in such a way that that the engine brake noise s.n their strength considerably reduced will.

Die Aufgabe ist erfindungsgeoäß dadurch gelöst, daß im Verbindungerohr in der Mähe des Motoreaugrohres eine Blende mit einem an die Blendenöffnung angesetzten, in Sichtung sum Motorsaugrohr sich erweiternden Trichter angeordnet ist.The object is achieved according to the invention in that in the connecting pipe near the motor eye tube a diaphragm with a to the diaphragm opening attached, in sighting sum engine suction pipe widening funnel is arranged.

Die erfindungsgemäße Ausbildung des Ansaugsystems bewirkt, daß beim Bremsen mit Hilfe der Brennkraftmaschine eine schwingende LuftsäuleThe inventive design of the intake system causes the Braking with the help of the internal combustion engine is an oscillating column of air

nur zwischen der Brennkraftmaschine und der Blende entstehen kann, da diese 6 ich nicht über den Trichter hinaus anzubreiten vermag. Diese Luftsäule ist so kurz, daß sie nicht in der Lage ist, eine größere Zahl von Bauteilen sub Schwingen anzuregen. Damit ist die Stärke der Hotorbreasgeräusche erheblich vermindert. Ee hat sich gezeigt, daß durch die Anordnung der Blende und des Trichters der Strömungswiderstand im Ansaugsystem nur geringfügig erhöht wird.can only arise between the internal combustion engine and the diaphragm, because I am not able to spread these 6 beyond the funnel. These The air column is so short that it is not able to stimulate a large number of components to oscillate. So that's the strength the hotorbreas noise is considerably reduced. Ee has shown that the flow resistance in the intake system is only slightly increased by the arrangement of the diaphragm and the funnel.

In einer vorteilhaften Ausgestaltung der Erfindung entspricht die Länge des Trichters in etwa dem Durchmesser des Verbinduqgerohres. Dadurch wird eine platzsparende Bauweise erreicht.In an advantageous embodiment of the invention, the length of the funnel corresponds approximately to the diameter of the connecting pipe. This results in a space-saving design.

Es let weiterhin vorteilhaft, wenn der größte Durchmesser dee Trichtere etwa 6O % des Innendurchmessers des Verbindungsrohres beträgt. Damit ergibt sich zwischen dem Trichter und der Wand des Verbindungsrohres ein Stauraum, der der Dämpfung der schwingenden Luftsäule dient.It is also advantageous if the largest diameter of the funnel is about 60 % of the inner diameter of the connecting pipe. This results in a storage space between the funnel and the wall of the connecting pipe, which is used to dampen the oscillating column of air.

Der größte Durchmesser des Trichters 7 ist wesentlich kleiner als der Innendurchmesser des Verbindungsrohres k, so daß zwischen dessen Wand und dem Trichter 7 ein Stauraum S entsteht, der der Dämpfung der schwingenden Luftsäule im Verbindungsrohr und im Ansaugrohr dient. Da Trichter 7 und Blende 6 hinter dem Luftfilter 3 angeordnet sind, ist ihr Verschmutzen ausgeschlossen.is about half the size of the diameter of the connecting pipe k. A funnel 7 adjoins the diaphragm 6 in the direction of flow of the air and widens in the direction of the engine intake manifold. The largest diameter of the funnel 7 is much smaller than the inner diameter of the connecting pipe k, so that a storage space S is created between its wall and the funnel 7, which serves to dampen the oscillating air column in the connecting pipe and in the intake pipe. Since the funnel 7 and the diaphragm 6 are arranged behind the air filter 3, it is impossible for them to get dirty.
