Description

Doppelrohr - Katalysator Double pipe catalytic converter

Die Erfindung betrifft einen Doppelrohr - Katalysator gemäß dem Oberbegriff des Anspruchs 1. The invention relates to a double-tube catalytic converter according to the preamble of claim 1.

Für Auspuffanlagen von Verbrennungsmaschinen werden zur Entgiftung von bleifreiem Kraftstoff Katalysatoren eingesetzt. For exhaust systems of internal combustion engines are used for detoxification catalytic converters are used by unleaded fuel.

Es ist bekannt, daß die Schadstoffe CO, CH und NO x in den Abgasen von Verbrennungskraftmaschinen, die mit einem bleilosen, fosilen Leichtöl betrieben werden, durch einen Katalysator in der Auspuffanlage nahezu vollständig unschädlich gemacht werden. It is known that the pollutants CO, CH and NO x in the exhaust gases of internal combustion engines operated with a unleaded, fosil light oil are almost completely harmless due to a catalytic converter in the exhaust system be made.

Der große Nachteil hierbei ist, daß dem Katalysator nur Abgase von bleifreiem Kraftstoff zugeführt werden dürfen. Bei Beaufschlagung mit Abgasen von bleihaltigem Kraftstoff ist die katalytisch aktive Schicht des Katalysators in kürzester Zeit zerstört. The big disadvantage here is that the catalyst only exhausts from unleaded fuel may be supplied. When exposed to exhaust gases of leaded fuel is the catalytically active layer of the catalyst in the shortest possible time Time destroyed.

Demgegenüber liegt der Erfindung die Aufgabe zugrunde, eine Auspuffanlage zu schaffen, die eine Zerstörung eines Katalysators verhindert. In contrast, the invention is based on the object of an exhaust system to create that prevents a catalytic converter from being destroyed.

Eine weitere Aufgabe wird darin gesehen, durch die Zuführung von Pressluft den Katalysator vollgastauglich zu machen, um damit die Lebensdauer eines Katalysators wesentlich zu erhöhen. Another task is seen in the supply of Compressed air makes the catalytic converter suitable for full gas to do in order to get the Significantly increase the service life of a catalytic converter.

Die Aufgabe wird bei einer gattungsgemäßen Einrichtung durch die kennzeichnenden Merkmale des Anspruchs 1 gelöst. The task is in a generic device by the characterizing features of claim 1 solved.

Der erfindungsgemäße Vorteil liegt besonders darin, daß bei Benutzung von Fahrzeugen, insbesondere bei Personenkraftwagen im internationalen (grenzüberschreitenden) Verkehr die Benutzung eines Kraftfahrzeuges mit Katalysator-Betrieb unproblematisch ist, weil nur eine Knopfbedienung am Armaturenbrett eines Fahrzeuges erforderlich ist, um von bleifreiem Kraftstoff-auf bleihaltigen Kraftstoffbetrieb umzuschalten. The advantage of the invention is particularly that when in use of vehicles, especially in the case of passenger cars in international (cross-border) Traffic the use of a motor vehicle with a catalytic converter is unproblematic is because only one button operation on the dashboard of a vehicle is required is to switch from unleaded fuel to leaded fuel operation.

Ein weiterer Vorteil besteht darin, daß in dem Rohrstutzen vor und hinter dem Katalysator mindestens eine Pressluftdüse eingesetzt ist, die temperaturabhängig Frischluft dem Katalysator zuführt, was bei längerem Vollgasbetrieb die Wirtschaftlichkeit und somit die Lebensdauer des Katalysators wesentlich erhöht. Another advantage is that in the pipe socket before and at least one compressed air nozzle is used behind the catalytic converter, which is temperature-dependent Fresh air is supplied to the catalytic converter, which is cost-effective for longer full throttle operation and thus the service life of the catalytic converter is significantly increased.

Anhand der Figuren wird ein Ausführungsbeispiel der Erfindung beschrieben. An exemplary embodiment of the invention is described with the aid of the figures.

Fig. 1 zeigt die Seitenansicht des Doppelrohr-Katalysators. Fig. 1 shows the side view of the double tube catalytic converter.

Fig. 2 zeigt die Draufsicht des Doppelrohr-Katalysators mit aufgebrochen dargestelltem Abgassammel-Behälter. Fig. 2 shows the plan view of the double tube catalytic converter with broken open illustrated exhaust gas collecting container.

Zur Vermeidung der Zerstörung von Katalysatoren bei Auspuffanlagen für Verbrennungsmotore werden die Abgase zunächst in einen Behälter 2 eingeleitet und beispielsweise mittels eines elektromagnetisch arbeitenden Schiebers 4 für eines der Auspuffrohre freigegeben. Die Schieberstellung wird beispielsweise auf elektrischem Wege einem Anzeigeinstrument am Armaturenbrett eines Fahrzeuges mitgeteilt und wird dort entsprechend optisch sichtbar. To avoid the destruction of catalytic converters in exhaust systems for internal combustion engines, the exhaust gases are first introduced into a container 2 and for example by means of an electromagnetically operating slide 4 for one the exhaust pipes released. The slide position is, for example, on electrical Ways a display instrument on the dashboard of a vehicle and is communicated visually visible there accordingly.

Die Test sonde 3 überwacht zusätzlich die Abgase im Behälter 2 und zeigt ebenfalls über ein Anzeigeinstrument am Armaturenbrett beispielsweise eines Personenkraftfahrzeuges an, ob bleifreien oder verbleiter Kraftstoff verbraucht wird. The test probe 3 also monitors the exhaust gases in container 2 and also shows, for example, one via a display instrument on the dashboard Passenger vehicle whether it consumes unleaded or leaded fuel will.

Die Düse 8 leitet in den Abgasstrom vor dem Katalysator 5 ständig Frischluft ein, der dadurch optimal gekühlt wird und dessen Lebensdauer dadurch wesentlich erhöht wird. The nozzle 8 leads continuously into the exhaust gas flow upstream of the catalytic converter 5 Fresh air, which is optimally cooled and thus its service life is increased significantly.

Durch die Zuschaltung der Düse 8a kann vor dem Katalysator jede erforderliche Druckstufe und somit eine optimale Kühlung erreicht werden. By switching on the nozzle 8a, any required Pressure level and thus optimal cooling can be achieved.
