Eine derartige Anordnung zeigt beispielsweise der japanische Patent­ abstract 58-35 218 (A). Dabei ist der Abgaskrümmer über eine Flansch­ verbindung in zwei Abschnitte unterteilt, wobei in dem unteren Ab­ schnitt eine Katalysatorpatrone eingesetzt ist, die sowohl in axialer Richtung als auch durch elastische Ringe radial verspannt ist.Such an arrangement is shown, for example, by the Japanese patent abstract 58-35 218 (A). The exhaust manifold has a flange connection divided into two sections, in the lower Ab cut a catalyst cartridge is used, both in axial Direction as well as radially braced by elastic rings.

Aufgabe der Erfindung ist es, eine Anordnung der gattungsgemäßen Art vorzuschlagen, die bei gutem Wirkungsgrad des Katalysators den hohen Temperaturschwankungen und Schwingungsbeanspruchungen zuverlässig standhält und die eine schnelle Montage bzw. Demontage des Katalysa­ tors ermöglicht.The object of the invention is to provide an arrangement of the generic type to propose the high efficiency of the catalyst Reliable fluctuations in temperature and vibration withstands and quick assembly and disassembly of the catalytic converter tors allows.

Diese Aufgabe wird erfindungsgemäß mit den Merkmalen des Patentan­ spruches 1 gelöst. Vorteilhafte Weiterbildungen der Erfindung sind den weiteren Patentansprüchen entnehmbar.This object is achieved with the features of the patent Proverb 1 solved. Advantageous developments of the invention are the other claims.

Erfindungsgemäß wird vorgeschlagen, den oder mehrere Katalysator in einem separaten Rahmen einzufassen und mit einem Zwischenflansch auszubilden, wobei der Zwischenflansch in die Flanschverbindung des Abgaskrümmers eingebunden wird. Daraus resultiert eine robuste und zuverlässige Halterung des Katalysators innerhalb des Abgaskrümmers, wobei zugleich eine unerwünschte Außenumströmung des Katalysators dauerhaft unterbunden ist. Mit dem Lösen der Flanschverbindung kann in einfacher Weise der Katalysator ausgetauscht werden. Der den Kata­ lysator aufnehmende Rahmen und der Zwischenflansch können durch ein­ fache Blechpreßteile gebildet sein, die untereinander und ggf. mit dem Katalysator verschweißt sind und als ein einheitliches Modul verbaut werden.According to the invention it is proposed that the catalyst or catalyst to be enclosed in a separate frame and with an intermediate flange form, the intermediate flange in the flange connection of the Exhaust manifold is integrated. This results in a robust and reliable mounting of the catalytic converter inside the exhaust manifold, an undesirable external flow around the catalyst is permanently prevented. With the release of the flange connection can the catalyst can be replaced in a simple manner. The Kata  frame and the intermediate flange can be replaced by a fold sheet metal parts to be formed with each other and possibly with are welded to the catalytic converter and as a single module be installed.

In fertigungstechnisch einfacher Weise kann der Abgaskrümmer durch einen oberen deckelförmigen Abschnitt - der den mit dem Zylinderkopf der Brennkraftmaschine verbindbaren Eintrittsflansch trägt - und einem unteren deckelförmigen Abschnitt mit einem Austrittsflansch ausgeführt sein. Solche Abschnitte sind sowohl gießtechnisch gut beherrschbar, können aber bevorzugt durch miteinander verschweißte, gewichtsgünstige Blechpreßteile gebildet sein.The exhaust manifold can pass through in a technically simple manner an upper lid-shaped section - the one with the cylinder head the inlet flange which can be connected to the internal combustion engine carries - and a lower lid-shaped section with an outlet flange be executed. Such sections are both good in terms of casting technology controllable, but can preferably by welded together, weight-favorable pressed sheet metal parts are formed.

Zur Erhöhung des Wirkungsgrades des oder der Katalysatoren können der obere Abschnitt des Abgaskrümmers und/oder der untere Abschnitt mit je einem den Katalysator vorgelagerten bzw. nachgeschalteten Aus­ gleichsvolumen ausgeführt sein, die einen vorteilhaften Ausgleich der Abgas-Druckwellen und eine Strömungsberuhigung bzw. eine überwiegend laminare Strömung im Katalysator sicherstellen.To increase the efficiency of the catalyst or catalysts, the upper section of the exhaust manifold and / or the lower section with one each upstream or downstream of the catalyst be carried out equal volume, which is an advantageous compensation of the Exhaust gas pressure waves and a flow calming or one predominantly Ensure laminar flow in the catalyst.

Die beiden Abschnitte 12, 14 sind mit einander benachbarten Flanschen 30, 32 versehen, über die mittels nicht dargestellter Schrauben eine gasdichte Flanschverbindung herstellbar ist.The two sections 12 , 14 are provided with adjacent flanges 30 , 32 , via which a gas-tight flange connection can be produced by means of screws, not shown.

Innerhalb des Abgaskrümmers 10 sind in dessen Längserstreckung (vgl. Fig. 2) die drei Einzelkatalysatoren 16, 18, 20 angeordnet. Dabei sind die Katalysatoren 16, 18, 20 jeweils in Quellmatten 34 eingepackt und in einem Rahmen 36 aus Stahlblech eingefaßt. (Vgl. auch Fig. 3). Die Rahmen 36 weisen kragenförmige Umbördelungen 38, 40 auf, um sowohl einen radialen als auch einen axialen Festsitz der Katalysatoren 16, 18, 20 in den Rahmen 36 sicherzustellen.The three individual catalytic converters 16 , 18 , 20 are arranged within the exhaust manifold 10 in its longitudinal extent (cf. FIG. 2). The catalysts 16 , 18 , 20 are each packed in swelling mats 34 and enclosed in a frame 36 made of sheet steel. (See also Fig. 3). The frames 36 have collar-shaped flanges 38 , 40 in order to ensure both a radial and an axial tight fit of the catalysts 16 , 18 , 20 in the frame 36 .

Die Rahmen 36 sind mit einem aus Flanschmaterial mit entsprechenden Durchbrüchen hergestelltem Zwischenflansch 42 verschweißt, dessen Flanschbild dem der Flansche 30, 32 entspricht. The frames 36 are welded to an intermediate flange 42 made of flange material with corresponding openings, the flange pattern of which corresponds to that of the flanges 30 , 32 .

Das aus den Katalysatoren 16, 18, 20 in Verbindung mit den Rahmen 36 und dem Flansch 42 gebildete Modul 44 ist in den unteren Abschnitt 14 des Abgaskrümmers 10 eingesetzt, wobei selbstverständlich unter Zwi­ schenfügung von nicht dargestellten Dichtungen der Zwischenflansch 42 in die Flanschverbindung 30, 32 eingebunden bzw. mit dieser ver­ schraubt ist.The module 44 formed from the catalytic converters 16 , 18 , 20 in connection with the frame 36 and the flange 42 is inserted into the lower section 14 of the exhaust manifold 10 , the intermediate flange 42 in the flange connection 30 , of course, with the interposition of seals, not shown, 32 integrated or screwed to it.
