Description
Die Erfindung bezieht sich auf eine Abgasleitung nach dem Oberbegriff des Anspruchs 1.The invention relates to an exhaust pipe according to the preamble of Claim 1.
Aus der DE 41 42 360 A1 ist eine doppelwandige Abgasleitung bekannt, die im Ringraum zwischen den Einzelrohrleitungen und der Kapselung einen Isolierstoff aufweist. Des weiteren ist aus der DE 40 21 563 A1 eine Abgasleitung bekannt, die eine Unterteilung besitzt. Ferner ist aus der US-PS 40 22 019 eine Abgasleitung bekannt, bei der die Einzelrohrleitungen in einem Rohrstutzen einmünden, der als Rohrtrichter ausgeführt ist.From DE 41 42 360 A1 a double-walled exhaust pipe is known, which in Annulus between the individual pipes and the encapsulation an insulating material having. Furthermore, an exhaust pipe is known from DE 40 21 563 A1, which has a subdivision. Furthermore, from US-PS 40 22 019 Exhaust pipe known, in which the individual pipes in a pipe socket flow out, which is designed as a pipe funnel.
Aufgabe der Erfindung ist es, eine Abgasleitung für eine Brennkraftmaschine zu schaffen, die in einfacher Weise mit einem Katalysator verbindbar ist und eine Wärmeisolierung gewährleistet.The object of the invention is to provide an exhaust pipe for an internal combustion engine create that is easily connected to a catalyst and a Thermal insulation guaranteed.
Die Aufgabe wird erfindungsgemäß durch die kennzeichnenden Merkmale des Anspruchs 1 gelöst. Weitere vorteilhafte Merkmale beinhalten die Unteransprüche.The object is achieved by the characterizing features of the Claim 1 solved. Other advantageous features include Subclaims.
Die mit der Erfindung hauptsächlich erzielten Vorteile bestehen darin, daß die vom Motor abzweigenden Einzelrohrleitungen - bestehend aus Innen- und Aussenrohren - zur Verbindung mit einem Abgaskatalysator zu einem Anschlusselement zusammengefaßt sind. Dies erfolgt in einem separat herstellbaren Rohrstutzen, der als Adapter für den Anschluß an den Katalysator dient. Dieser ist baulich einfach herstellbar und schafft eine Anschlußmöglichkeit der vier oder auch mehr Einzelrohrleitungen mit einer Anschlußleitung des Abgaskatalysators. Hierzu sind die im Rohrstutzen fortgeführten Einzelrohrleitungen bis zum Befestigungsflansch mit dem Katalysator derart zusammengedrückt, daß sich vier im Querschnitt dreieckförmige Rohrelemente bilden, die miteinander verbunden sind, beispielsweise durch eine Schweißung. Diese sind in einer Bohrung des Befestigungsflansches durch Schweißen befestigt. The main advantages achieved with the invention are that individual pipelines branching off the engine - consisting of internal and Outer tubes - for connection with an exhaust gas catalytic converter to one Connection element are summarized. This is done in a separate producible pipe socket, which as an adapter for connection to the catalyst serves. This is structurally easy to manufacture and creates a connection option of the four or more individual pipelines with a connecting line of the Catalytic converter. For this purpose, those continued in the pipe socket Single pipes up to the mounting flange with the catalyst in this way compressed that there are four tubular elements triangular in cross section form, which are connected to each other, for example by welding. These are in a hole in the mounting flange by welding attached.
Die Rohrstücke im Rohrstutzen sind auf oder in die Einzelrohre der Abgasleitung gesteckt und weisen einen Schiebe- oder Lossitz auf, wodurch bei den hohen herrschenden Temperaturen in der Abgasleitung keine Verspannungen auftreten können.The pipe sections in the pipe socket are on or in the individual pipes of the exhaust pipe inserted and have a sliding or loose seat, which means at high prevailing temperatures in the exhaust pipe no tension can.
Der Rohrstutzen weist eine Gehäusekapsel auf, bei der zwischen den Rohrstücken ein Luftraum gebildet wird, der bei den Einzelrohren durch Außenrohre fortgeführt wird, so daß sich vom Anschluss am Motor bis unmittelbar zum Katalysator ein durchgehender Luftraum und somit eine durchgehende Wärmeisolierung ergibt.The pipe socket has a housing capsule, in which between the Pipe pieces an air space is formed by the individual pipes Outer tubes is continued, so that from the connection to the engine a continuous air space directly to the catalytic converter and thus one continuous thermal insulation results.
Eine Verbindung der Gehäusekapsel mit den jeweiligen Einzelrohrleitungen erfolgt etwa über auf die Aussenrohre der Einzelrohrleitungen geschobene Formringe, welche mit den Außenrohren sowie mit der Gehäusekapsel verschweißbar sind.A connection between the housing capsule and the individual pipelines takes place, for example, by pushing onto the outer pipes of the individual pipes Form rings, which with the outer tubes and with the housing capsule are weldable.
Ein Übertritt der Lufträume von den Einzelrohrleitungen in die Gehäusekapsel erfolgt im Bereich der Formringe.A passage of the air spaces from the individual pipelines into the housing capsule takes place in the area of the form rings.
Der Rohrstutzen wird durch ein Verpressen seiner Rohrstücke zu einem rohrkreisförmigen Querschnitt in einem oder mehreren Arbeitsgängen verformt. Eine Verbindung mit der Gehäusekapsel erfolgt im Befestigungsflansch durch eine Schweißung, wobei der Formring Z-förmig ausgeführt ist und eine Verbindung zum Außenrohr der Einzelrohrleitungen herstellt und eine Wärmeausdehnung zulässt.The pipe socket becomes one by pressing its pipe sections tubular cross-section deformed in one or more operations. A connection to the housing capsule is made in the mounting flange a weld, the form ring is Z-shaped and a Connects to the outer pipe of the individual pipes and a Allows thermal expansion.
