Description

Auspuffendrohr für H@ckmotoro@ spez. VW Beschreibung 1 Die Neuerung betrifft eine Auspuffblende die wahlweise mit Düsen-oder zylindrischen Siebeinsatz bei Heckmotoren (spez.VW) Verwendung findet.Exhaust tailpipe for H @ ckmotoro @ spec. VW Description 1 The innovation relates to an exhaust cover which is optionally available with a nozzle or a cylindrical sieve insert is used in rear engines (especially VW).

Hche PS-Zahlen niedrige Phonwerte und gute Verbrennung des Kraftmtoffes (niedriger CO-G@halt) werden heute von modermen Automobilen verlangt.High horsepower, low phon values and good fuel combustion (low CO-G @ stop) are required of modern automobiles.

Es sind unter anderem konische Auspuffrohre mit düsenartigem Einsatz und sich nach hinten erweiternden perforierten Blech bekannt und diese vereinigen in sich in etwa die vorgenannten Eigenschaften.Among other things, there are conical exhaust pipes with a nozzle-like insert and perforated plate widening towards the rear are known and unite them in itself roughly the aforementioned properties.

Die konische Form des Außenrohres hat jedoch den Nachteil,dasz das @inbringen der schalldämpfenden Masse nur beschränkt und ungleichmäßig möglich ist. Die schalldämpfende Masse wird deshalb oft nach kurseer Zeit schon herausgeblasen.Außerdem unterliegt der perforierte Einsats am Austrittsende einer starken Korrosion die zudem noch im Stand durch Regen oder Nebel begünstigt wird.However, the conical shape of the outer tube has the disadvantage that the Bringing in the sound-absorbing compound is only possible to a limited extent and unevenly. The sound-absorbing compound is therefore often blown out after the course has elapsed the perforated insert is subject to severe corrosion at the outlet end is also favored by rain or fog while standing.

Diese Nachteile werden bei der vorliegenden Neuerung in hohem Masse vermieden.These disadvantages are to a large extent with the present innovation avoided.

Das Endrohr besteht aus zwei zylindrischen Rohren ( A und B ) die durch schweißen,löten oder falsen miteinander verbunden sind.In diesen äußeren Rohrmantel wird das mit schalldämpfender Hasse (D) fest und gleich@äßig umwickelte sich nach hinten erweiternde Sieb (E) in das größere zylindrische Rohr (A) eingeschoben bis der am hinteren Ende des perforierten Bl@ches sich befindende konische passring (@) den Düseneinsatz fest im großen zylindrische Rohr (A) abschließt und ohne jede weitere Befestigung abstütst.The tailpipe consists of two cylindrical tubes (A and B) which are connected to one another by welding, soldering or folding in this outer pipe jacket that is fixed with sound-absorbing hatred (D) and evenly wrapped around itself after The sieve (E) widening at the rear is pushed into the larger cylindrical tube (A) the conical fitting ring located at the rear end of the perforated leaf (@) closes the nozzle insert tightly in the large cylindrical tube (A) and without any support further fastening.

Neben dem Leistungaverbesserndem Düsen-Siebeinsats kanz such der bisher bei VW übliche zylindrische Siebeinsats Verwendung finden.In addition to the performance-improving nozzle-sieve insert, the so far has been looking for Cylindrical sieve inserts customary at VW are used.

Das am kleineren Ende befindlichte Düsenrohr(G) wird anschließend mit dem äußeren Mantel (B) am Ende (H) durch schweisen, löten oder sicken fest verbunden.The nozzle tube (G) at the smaller end is then firmly connected to the outer jacket (B) at the end (H) by welding, soldering or beading.

Um einen kontinierlichen Austritt der Abgase zu gewährleisten hat es sich als vorteilhaft erwiesen die Eintrittsöffung (H) absu@chrägen oder mit Löchern bezw. Schlitzen zu versehen.In order to ensure a continuous discharge of the exhaust gases it has proven to be advantageous to slope the inlet opening (H) or with holes respectively To provide slots.
