Abstract

Exhaust gas construction comprises a reverberation absorber (1) having several chambers. At least one exhaust gas pipe connected to an internal combustion engine enters one of the chambers and exhaust gas pipes (2, 3) leaving the chambers are connected to end pipes (4, 5). The exhaust gas pipes in the reverberation absorber are arranged perpendicularly to the vehicle and approximately facing each other, and have a pipe bend (2a, 3a) positioned in a vertical plane.

Description

Die Erfindung bezieht sich auf eine Abgasanlage nach dem Oberbegriff des Patentanspruchs 1.The invention relates to an exhaust system according to the preamble of Patent claim 1.

Aus der US5773770 ist gemäß der Fig. 1 and 5 ein Abgaschalldämpfer bekannt, der in einer horizontalen Einbaulage liegt und ein Oberteil 16 und ein Unterteil 17 besitzt.From US5773770, according to FIGS. 1 and 5, an exhaust silencer is known, which lies in a horizontal installation position and has a top 16 and a bottom 17.

Bei Geländefahrzeugen, die eine Wattauglichkeit aufweisen, besteht das Problem darin, daß bei einer Durchfahrt im Wasser, dieses in die Endrohre und somit in die Abgasrohre und nachfolgend in den Motor eintreten kann. Es sind hierzu in den Abgasrohren Klappen und dgl. Einrichtungen bekannt, Welche bei einer Wasserdurchfahrt ein Eintreten von Wasser in die Abgasrohre bzw. in die Abgasanlage verhindern sollen.For all-terrain vehicles that are suitable for wattage, the problem is that at a passage in the water, this in the tailpipes and thus in the exhaust pipes and subsequently enter the engine. There are this purpose in the exhaust pipes flaps and the like. Facilities known, which in a water passage an occurrence of To prevent water in the exhaust pipes or in the exhaust system.

Aufgabe der Erfindung ist es, eine einfach auszubildende Abgasanlage mit einem Nachschalldämpfer zu schaffen, die einen Wassereintritt bis zu einer gewissen Wattiefe in einfacher Weise verhindert.The object of the invention is to provide a simple trainee exhaust system with a Rear silencer to create a water ingress to a certain fording depth in easily prevented.

Diese Aufgabe wird erfindungsgemäß durch die Merkmale des Schutzanspruchs 1 gelöst. Weitere vorteilhafte Merkmale beinhalten die Unteransprüche.This object is achieved by the features of claim 1 protection. Further advantageous features include the subclaims.

Ein Eintritt von Wasser in eine Brennkraftmaschine wird vorteilhafterweise dadurch vermieden, daß die mit den Endrohren der Abgasanlage unmittelbar verbundenen Abgasrohre jeweils einen in einer senkrechten Querebene aufgerichteten Rohrbogen, einen sogenannten Siphonbogen aufweisen. Die beiden Abgasrohre verlaufen quer zum Fahrzeug und sind nahezu gegenüberliegend angeordnet Die Rohrbogen erstrecken sich etwa gemeinsam in der senkrechten Querebene.An entry of water into an internal combustion engine is advantageously characterized avoided that directly connected to the tailpipes of the exhaust system Exhaust pipes in each case one erected in a vertical transverse plane pipe bend, have a so-called siphon arc. The two exhaust pipes run transversely to the Vehicle and are arranged almost opposite each other The pipe elbows extend approximately together in the vertical transverse plane.

Eine Befestigung der Abgasrohre im Nachschalldämpfer erfolgt vorzugsweise im Bereich des Rohrbogens über mindestens eine Zwischenwand.An attachment of the exhaust pipes in the rear silencer is preferably carried out in the area of the pipe bend over at least one partition.

Die Rohrbögen bewirken eine solche Pegelerhöhung gegenüber den tiefergelegenen Endrohren, daß eine gewisse Wattiefe des Fahrzeugs gewährleistet ist und kein Wasser vom Nachschalldämpfer in die weitere Abgasanlage eintreten kann. Hierzu ist das Endrohr wesentlich tiefer gelegen als der Rohrbogen.The pipe bends cause such a level increase compared to the lower level Tailpipes that a certain fording depth of the vehicle is guaranteed and no water From the rear silencer in the other exhaust system can occur. This is the Tailpipe located much lower than the pipe bend.

Falls trotzdem Wasser in die Abgasrohre eintritt, können diese über eine vorhandene Kondensatabsaugung entleert werden.If, nevertheless, water enters the exhaust pipes, they can over an existing Condensate extraction be emptied.

Ein Ausführungsbeispiel ist in der Zeichnung dargestellt, welches einen Nachschalldämpfer mit innenliegenden Abgasrohren und Rohrbögen zeigt.An embodiment is shown in the drawing, which is a Rear muffler with internal exhaust pipes and pipe bends shows.

Der Nachschalldämpfer umfaßt im wesentlichen ein Gehäuse 1, in dem die Abgasrohre 2 und 3 dargestellt sind, welche endseitig bei 4 und 5 mit Endrohren versehen sind, aus denen die Abgase austreten.The rear silencer essentially comprises a housing 1 in which the exhaust pipes 2 and 3, which are provided at end ends at 4 and 5 with tailpipes where the exhaust gases escape.

Der Abgasstrom von der Brennkraftmaschine wird über die Eintrittsrohre 6, 7 in den Abgasschalldämpfer bzw. in die Kammern des Nachschalldämpfers 1 geleitet und über die Abgasrohre 2 und 3 zu den Endrohren 4, 5 geführt.The exhaust gas flow from the internal combustion engine is via the inlet pipes 6, 7 in the Exhaust silencer or passed into the chambers of the rear silencer 1 and over the exhaust pipes 2 and 3 to the tail pipes 4, 5 out.

Die Abgasrohre 2 und 3 sind querliegend zum Fahrzeug im Nachschalldämpfer 1 angeordnet und weisen jeweils einen aufrechten Rohrbogen 2a und 3a auf, die sich in einer senkrechten Querebene im Fahrzeug befinden.The exhaust pipes 2 and 3 are transverse to the vehicle in the rear silencer. 1 arranged and each have an upright pipe bend 2a and 3a, which in a vertical transverse plane located in the vehicle.

Die Rohrbögen 2a, 3a weisen zur Normal-Pegelhöhe N der Endrohre 4, 5 eine Pegelhöhe h auf, die der Wattiefe des Fahrzeugs entspricht.The pipe bends 2a, 3a have the normal level height N of the tail pipes 4, 5 a Level height h, which corresponds to the wading depth of the vehicle.

Die Abgasrohre 2, 3 sind jeweils im Nachschalldämpfer in mindestens einer Wand 8, 9 gehalten, so daß eine aufrechte Lage des Rohrbogens 2a, 3a im Nachschalldämpfer 1 gewährleistet istThe exhaust pipes 2, 3 are each in the rear silencer in at least one wall 8, 9th held so that an upright position of the pipe bend 2a, 3a in the rear silencer. 1 is guaranteed
