Abstract

The bypass duct, invented by me, for an exhaust-gas catalyser is a device which allows the driver to switch off the exhaust-gas catalyser (which will be compulsory in the Federal Republic of Germany from 1986) rapidly and in an effective manner for certain situations, for example in the case of a holiday in another European country where lead-free petrol will not be obtainable and he will thus have to use leaded petrol, which is harmful to exhaust-gas catalysers. As is known, leaded petrol destroys conventional exhaust-gas catalysers within a very short time. Using the bypass duct for the exhaust-gas catalyser, any driver can now help to maintain the effectiveness of his exhaust-gas catalyst in the long term.

Description

Bezeichnung der Erfindung:Title of the invention:

Abgaskatalysator- bypass- Kanal Beschreibung der Erfindung umseitig Beschriebung der Erfindung: Blatt 1 Die Erfindung betrifft die Möglichkeit der kurzfristigen Abschaltung herkömmlicher Katalysatoren für bestimmte Situationen" zum ispjel wenn kein bleifteies Benzin zur Verfügung t,und die gleichzeitige Umleitung bleihaltiger, für den Katalysator schädlicher. Abgase durch einen Abgaskatalysator- bypass- Kanal.Catalytic converter bypass channel Description of the invention overleaf Description of the invention: Sheet 1 The invention relates to the possibility of short-term Shutdown of conventional catalytic converters for certain situations "to the ispjel if no unleaded petrol available, and the simultaneous diversion of unleaded, more harmful to the catalytic converter. Exhaust gases through a catalytic converter bypass channel.

Die Umleitung von für einen herkömmlichen Abgaskatalysator schädlichen ( bleihaltigen Gasen ) Abgasen will ich hier erörtern.The diversion of harmful for a conventional catalytic converter (lead-containing gases) exhaust gases I want to discuss here.

Wie aus meiner Zeichnung ersichtlich ist, befindet sich der Abgaskatalysator und der Abgaskatalysator- bypass- Kanal in einem Gehäuse, die von einer Trennwand getrennt sind.As can be seen from my drawing, there is the catalytic converter and the catalytic converter bypass duct in a housing that is supported by a partition are separated.

Über zwei Abgassteuerklappen, die über ein Steuergestänge mechanisch bewegt werden können, hat nun der Kraftfahrer über einen Hebel im Wageninneren, der ebenfalls mechanisch mit dem Steuergestänge in Verbindung steht, die Möglichkeit beide Abgassteuerklappen gleichzeitig von Punkt A zu Punkt B oder von Punkt B zu Punkt j zu bewegen.Via two exhaust control flaps, which are mechanically operated via a control linkage can be moved, the driver now has a lever inside the vehicle, which is also mechanically connected to the control linkage, the possibility both exhaust gas control flaps simultaneously from point A to point B or from point B to Move point j.

Die Abgassteuerklappen, die eine bewegliche Verlängerung der Trennwand darstellen, ermöglichen es also in der Stellung A bleifreie, für den Abgaskatalysator unschadliche Abgase durch den Katalysator und in der Stellung B bleihaltige, für den Abgaskatalysator schädliche Abgase durch den Abgaskatalysator- bypass- Kanal zu leiten.The exhaust control flaps, which are a movable extension of the partition represent, so make it possible in position A lead-free, for the catalytic converter harmless exhaust gases through the catalytic converter and lead-containing in position B, for Exhaust gases harmful to the catalytic converter through the catalytic converter bypass channel to direct.

Beschreibung der Erfindung: Blatt 2 Die ebenfalls eingezeichnete Druckfeder hat die Aufgabe, daß bei einer über einen Bowdenzug ( der sich für die Übertragung von Druckkräften nicht eignet) erstellten mechanischen Verbindug von Steuerhebel zu Steuergestänge die Abgasumlenkklappennstellung B erreicht werden kann.Description of the invention: Sheet 2 The compression spring also drawn has the task of having a Bowden cable (which is used for the transmission not suitable for compressive forces) created mechanical connection of control lever to control linkage the exhaust flap position B can be reached.

Sie kann al so entfallen, wenn eine auch auf Druck belastbare Verbindung von Steuerhebel zu Steuergestänge Verwendung findet.It can therefore be omitted if a connection that can also be subjected to pressure from control lever to control linkage is used.

Ferner' könnte die hintere, rechts gezeichnete Steuerklappe, die für die Abgasweiterleitung verantwortlich ist, entfallen, wenn sichergestellt wäre, daß bei Abgaskatalysator- bypass-Kanalbetrieb keine schädlichen (bleihaltigen) Abgase den Katalysator erreichen könnten.Furthermore, the rear control flap, shown on the right, which is used for the exhaust gas forwarding is responsible, do not apply if it is ensured that that there are no harmful (lead-containing) exhaust gases in the exhaust gas catalytic converter bypass channel operation could reach the catalyst.
