Abstract

The air induction system has a collecting manifold, from which individual induction channels lead to the cylinders, and one or more adaptors for the component pieces of the channels. Each individual channel has a short cut channel. The short cut channels (10) are switched by a common switching valve (11) in the collecting induction manifold. This valve is fitted within the beds (15,16) of one of the component pieces (4) and adaptors (14). When it opens, it turns into the collecting induction manifold.

Description

Die Erfindung betrifft ein Lufteinlaßkanalsystem für Brennkraftmaschinen nach dem Oberbegriff des Anspruchs 1.The invention relates to an air intake duct system for internal combustion engines according to the Preamble of claim 1.

Ein derartiges Lufteinlaßkanalsystem ist in der DE-U1-89 14 049 angegeben und ermöglichst es, daß alle Einzelteile im Druckgußverfahren herstellbar sind, wobei erwähnt ist, daß ggf. auch eine Vorrichtung zur Umschaltung auf kürzere Ansauglän­ gen verwendet werden kann.Such an air intake duct system is specified in DE-U1-89 14 049 and enables that all individual parts can be produced in the die casting process, whereby is mentioned that, if necessary, a device for switching to shorter Ansauglän gene can be used.

Eine solche Vorrichtung ist in der DE-U1-89 06 045 angegeben, wobei jeder Ein­ zelansaugkanal einen Kurzschlußkanal aufweist, der in Abhängigkeit von Betriebs­ kenngrößen der Brennkraftmaschine zur Verkürzung der Ansauglänge durch eine Schaltklappe in den Sammeleinlaßkanal hinein geöffnet werden kann.Such a device is specified in DE-U1-89 06 045, each one zelansaugkanal has a short-circuit channel, which is dependent on operation Characteristics of the internal combustion engine to shorten the intake length by Switch flap can be opened into the collective inlet duct.

Bei dem Ausführungsbeispiel ist vorgesehen, daß wenigstens immer zwei Schalt­ klappen auf einer Schaltklappenwelle angeordnet sind mittels Verschraubung, Vernietung oder Verschweißung.In the embodiment, it is provided that at least always two switching flaps are arranged on a switching flap shaft by means of screwing, Riveting or welding.

Hierfür ist jedoch ein erheblicher Montageaufwand nötig, wobei das Risiko des Lösens der Klappen besteht, das eine Zerstörung der Brennkraftmaschine zur Folge hätte. Die aus Flachblech hergestellten Klappen weisen darüber hinaus strömungs­ technische Nachteile auf.However, this requires a considerable amount of assembly work, the risk of Loosening the flaps there is a destruction of the engine would have. The flaps made of flat sheet also have flow technical disadvantages.

Hiervon ausgehend liegt der Erfindung die Aufgabe zugrunde, Maßnahmen auf­ zufinden, mit denen ein gattungsgemäßes Luftansaugkanalsystem durch weniger Bauteile herstellbar, einfach montierbar wird, wobei diese Maßnahmen zusätzlich eine stromungstechnische Optimierung bewirken sollen. Proceeding from this, the object of the invention is to implement measures find with which a generic air intake duct system by less Components can be manufactured, can be easily assembled, these measures additionally being a to optimize electrical engineering.  

Diese Aufgabe ist durch die im Anspruch 1 angegebenen Merkmale gelöst worden. Vorteilhafte Weiterbildungen sind in den Unteransprüchen angegeben.This object has been achieved by the features specified in claim 1. Advantageous further developments are specified in the subclaims.

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und wird nachfolgend beschrieben.An embodiment of the invention is shown in the drawing and will described below.

Die Zeichnung zeigt:The drawing shows:

Fig. 1 eine Teilansicht eines Schnittes durch ein Luftansaugkanalsystem; Figure 1 is a partial view of a section through an air intake duct system.

Fig. 2 einen Schnitt aus Fig. 1, Fig. 2 shows a section of Fig. 1,

Fig. 3 eine Einzelheit aus Fig. 2. Fig. 3 shows a detail from FIG. 2.

Fig. 1 zeigt einen Querschnitt eines Luftansaugkanalsystems 1 einer Brennkraftma­ schine, aus dem ein Zylinderkopf 2 der Brennkraftmaschine sowie eine Teilungsebene 3 von Dichtflächen zweier Teilstücke 4, 5 erkennbar sind, die miteinander ver­ schraubt das Luftansaugkanalsystem 1 bilden. Dieses weist einen zentral angeord­ neten Sammeleinlaßkanal 6 auf, in den ein nicht dargestellter Lufteinlaßkanal ein­ mündet, der von einer Drosseleinrichtung kontrolliert wird. Von dem Sammelein­ laßkanal 6 zweigen spiralförmig ausgebildete, zu den Zylindern der Brennkraftmaschi­ ne führende Einzelansaugkanäle 9 ab, wobei jeder dieser Kanäle 9 über einen Kurzschlußkanal 10 direkt mit dem Sammeleinlaßkanal 6 verbunden werden kann, wenn eine in den Kurzschlußkanälen 10 angeordnete Schaltklappe 11 in Öffnungs­ stellung gebracht wird. Mit diesen Schaltklappen 11 kann je nach Betriebsart der Brennkraftmaschine eine Steuerung der Einzelansaugkanallängen (kurz oder lang) erfolgen. Fig. 1 shows a cross section of an air intake duct system 1 of an internal combustion engine, from which a cylinder head 2 of the internal combustion engine and a parting plane 3 of sealing surfaces of two sections 4 , 5 can be seen, which screw together to form the air intake duct system 1 . This has a centrally arranged collection inlet duct 6 , into which an air inlet duct (not shown) opens, which is controlled by a throttle device. From the Sammelein laßkanal 6 spiral-shaped, ne to the cylinders of Brennkraftmaschi leading Einzelansaugkanäle 9 branch off, each of these channels 9 can be connected via a short-circuit channel 10 directly with the collecting intake passage 6 when arranged in the shorting channels 10 switching valve 11 in open position brought. Depending on the operating mode of the internal combustion engine, these switching flaps 11 can be used to control the individual intake duct lengths (short or long).

Die in bezug auf den Sammeleinlaßkanal 6 innenliegenden Wandungen 12 der Ein­ zelansaugkanäle 9 und die Wandung 13 des Sammeleinlaßkanals 6 sind von einem spiralförmigen Paßstück 14 gebildet, das von den Dichtflächen ausgehend in die entsprechenden Ausnehmungen der Teilstücke 4, 5 eingesetzt ist.The in relation to the collecting inlet channel 6 inner walls 12 of a single suction channels 9 and the wall 13 of the collecting inlet channel 6 are formed by a spiral fitting 14 , which is used starting from the sealing surfaces in the corresponding recesses of the sections 4 , 5 .

Erfindungsgemäß ist nun vorgesehen, daß die Kurzschlußkanäle 10 von einer gemeinsamen, im Sammeleinlaßkanal 6 gelagerten Schaltklappe 11 geschaltet werden, wobei die Schaltklappe 11 innerhalb von Lagerflächen 15, 16 eines der Teilstücke 4 und des/der Paßstücke 14 gelagert ist und bei Öffnung in den Sammel­ einlaßkanal 6 hineinschwenkt (Strichpunktlinie).According to the invention it is now provided that the shorting channels are switched 10 6 mounted switching flap from a common, in the common intake channel 11, whereby the switching flap is supported within the bearing surfaces 15, 16 of one of the sections 4 and the / the fitting pieces 14 11 and opening into the collection inlet duct 6 swings in (chain line).

Durch die als ein Druckgußteil herstellbaren Schaltklappen 11 und durch die ebenfalls im Druckgußverfahren hergestellten Lagerflächen 15, 16 entfällt die bei Luftansaug­ kanalsystemen des Standes der Technik übliche mechanische Bearbeitung. Die Montage ist sehr einfach auszuführen. Es ist sehr vorteilhaft, für die Abdichtung der Einzelansaugkanäle 9 gegeneinander, wenn die Schaltklappe 11 den einzelnen Trennwänden 17 der Einzelansaugkanäle 9 zugeordnete Stege 18 aufweist, die Schlitze 19 bilden, in die die hier U-förmigen Trennwände 17 beim Schließen ein­ tauchen, wie aus Fig. 2 und 3 entnehmbar ist, in denen ein Schnitt aus Fig. 1 darge­ stellt ist.Due to the switch flaps 11 which can be produced as a die-cast part and the bearing surfaces 15 , 16 which are likewise produced in the die-casting process, the mechanical processing customary in the case of air intake duct systems of the prior art is eliminated. The assembly is very easy to do. It is very advantageous for the sealing of the individual intake ducts 9 against one another if the switching flap 11 has the webs 18 assigned to the individual partition walls 17 of the individual intake ducts 9 , which form slots 19 , into which the U-shaped partition walls 17 dip when closing, such as Fig. 2 and 3 can be removed, in which a section of Fig. 1 is Darge.

Diese Schnitte zeigen die Querschnitte der Einzelansaugkanäle 9, gebildet aus Wänden des Teilstückes 5 und den Trennwänden des Paßstückes 14, sowie die geschlossen dargestellten Schaltklappen 11. Die Lagerflächen 15 befinden sich an mit dem Teilstück 4 einstückig gegossenen Lagerböcken 20, die Lagerflächen 16 befinden sich an dem Paßstück 14. Die Schaltklappen 11 weisen an den Enden Lagerzapfen 21 auf, die, wie erwähnt, von den Lagerflächen 15, 16 gelagert werden, es können jedoch zusätzliche Lagerböcke/Lager zwischen den Enden vorgesehen sein.These sections show the cross sections of the individual intake ducts 9 , formed from walls of section 5 and the partitions of fitting piece 14 , and the switching flaps 11 shown closed. The bearing surfaces 15 are located on bearing blocks 20 cast in one piece with the section 4 , the bearing surfaces 16 are located on the adapter 14 . The switching flaps 11 have bearing pins 21 at the ends which, as mentioned, are supported by the bearing surfaces 15 , 16 , but additional bearing blocks / bearings can be provided between the ends.

Für einen günstigen Lufteinlauf bei geöffneter Schaltklappe (in Strichpunktlinie darge­ stellt) ist vorgesehen, daß die Schaltklappe 11 an ihrem zum Lagerdrehpunkt 22 äußeren Ende und die Kurzschlußkanäle an der mit diesem Ende korrespondierenden Wand Einlaufwülste 23, 24 aufweisen. For a favorable air inlet when the switching flap is open (in dash-dotted lines represents Darge) it is provided that the switching flap 11 have inlet beads 23 , 24 at their outer end to the bearing pivot 22 and the short-circuit channels on the wall corresponding to this end.

Wie in Fig. 2 dargestellt ist, kann die Schaltklappe 11 eine zum Lagerdrehpunkt 22 beabstandete Einhängeöffnung 25 aufweisen, in die eine Schubstange 26 eingehängt ist, die direkt oder über einen Umlenkhebel mit einem Stellelement verbunden ist.As shown in FIG. 2, the switching flap 11 can have a suspension opening 25 spaced apart from the pivot point 22 , into which a push rod 26 is suspended, which is connected directly or via a bell crank to an actuating element.

In Abänderung der Ausführung nach Fig. 1 und 2, der Vorstellbarkeit wegen nicht extra dargestellt, kann nur jede 2-te/x-te Trennwand 17 zwischen den Einzelansaug­ kanälen 9 durch Stege 18 der Schaltklappe 11 umfaßt sein.In a modification of the embodiment according to FIGS. 1 and 2, for the sake of conceivability not shown separately, only every 2nd / xth partition 17 between the individual suction channels 9 can be encompassed by webs 18 of the switching flap 11 .

Mit der erfindungsgemäßen Ausführung des Luftansaugkanalsystems liegt eine mit geringen im Druckgußverfahren herstellbaren Bauteilen zu realisierende Lösung vor, die einfach zu montieren ist und strömungstechnische Vorteile aufweist.With the embodiment of the air intake duct system according to the invention, one is included low number of components that can be produced in the die casting process, which is easy to assemble and has advantages in terms of flow technology.
