Abstract

The effectiveness of the invention is based on the fact that the high combustion temperatures occurring in internal combustion engines are utilised for the elimination of pollutants. The different composition of combustion exhaust gases here makes it possible to use differently functioning catalytic converters, which exhibit their effectiveness only with heating to correspondingly high temperatures. The exhaust catalytic converter cartridge is adapted in form to the particular engine to which it is to be retrofitted and is inserted into the existing exhaust duct directly between the cylinder head and exhaust connection, where the cartridge, by virtue of its design, is automatically fixed without further attachment. Due to the arrangement of the exhaust catalytic converter cartridge a silencing effect is also brought about. The explosion sound wave emitted is not, as hitherto, fully introduced into the exhaust pipe system as far as the first silencer stage. This results in a reduction of the engine noise in the engine area, which in load operation results in a lowering of the noise level and of the low-frequency roaring noise. The device is characterised by the fact that it does not need maintenance and can easily be exchanged in the event of wear.

Description

Beschreibungdescription

Abgaskatalysatorpatrone zur Nachverbrennung und Schalldämpfung an Brennkraftmaschinen,Catalytic converter cartridge for afterburning and soundproofing on internal combustion engines,

Die Erfindung bezieht sich auf einen Abgaskatalysator welcher zwischen Zylinderkopf und Abgasstutzen als Patrone eingesetzt wird.Gleichzeitig wirkt diese Abgaskatalysatorpatrone bis zum gewissen Grad als Schallabsorbierer. ·The invention relates to an exhaust gas catalytic converter which is used between the cylinder head and the exhaust gas nozzle This catalytic converter cartridge works at the same time to a certain extent as a sound absorber. ·

Abgaskatalysätoren werden bislang als baueigenes Zusatzteil in die Abgasleitung eingebaut.Diese bis Jetzt bekannten Vorrichtungen zur Abgasreinigung sind nicht immer in der Lage - vor allen Dingen im Teillastbetrieb festen Kohlenstoff,wie Rußpartikel und erhöhte Öldampfkonzentrationen und daraus resultierende Verbrennungsanteile zu assimilieren.Dieses führt zum Verstopfen oder Verkleben der bis jetzt bekannten Katalysatoren.Up to now, catalytic converters have been built into the exhaust pipe as a built-in additional part. These devices for exhaust gas purification, which have been known up to now, are not always capable - especially in partial load operation, solid carbon such as soot particles and increased oil vapor concentrations and to assimilate the resulting combustion fractions. This leads to clogging or Bonding of the catalysts known up to now.

1515th

Des weiteren besteht bei den bis jetzt bekannten zentral wirkenden Katalysatoren die Gefahr der Überhitzung des Katalysators sobald nur eine Zylindereinheit den ihr zugeführten Kraftstoffanteil nicht oder nur teilweise verbrennt. Die Folge ist Zerstörung des Katalysators,mögliches in Brand setzen des Fahrzeugs.Furthermore, there is a risk of overheating of the centrally acting catalytic converters known up to now Catalyst as soon as only one cylinder unit does not burn or only partially burns the fuel supplied to it. The consequence is destruction of the catalytic converter, possible setting of the vehicle on fire.

Hier will die Erfindung in der Form Abhilfe schaffen,daß die zuvor genannten Nachteile nicht mehr gegeben sind.Here the invention wants to remedy the situation in the form that the aforementioned disadvantages no longer exist.

Dieses wird erreicht durch den Einsatz der Katalysatorpatrone in der heißen Abgaszone.Die Wirkungsweise beruht darauf,daß die in der Patrone befindliche Edelstahlfaser durch die Verbrennungsabgase auf die Zündtemperatur von Kohlenstoff und seinen Verbindungen gebracht wird und dadurch eine Nachverbrennung mit dem Restsauerstoff, der Verbrennungsluft, gegeben ist. This is achieved through the use of the catalytic converter cartridge in the hot exhaust gas zone ensure that the stainless steel fibers in the cartridge are reduced to the ignition temperature of Carbon and its compounds is brought and thereby an afterburning with the residual oxygen, the combustion air, is given.

Im folgenden wird die Erfindung anhand von lediglich einen Ausführungsweg darstellenden Zeichnung näher erläutert. Es zeigt Figur 1 den grundsätzlichen erfindungsgemäßen Aufbau der Abgaskatalysatorpatrone in perspekti- - vischer Darstellung.Der runde Körper (1) aus hitzebeständigem Stahl dient zur Aufnahme des Katalysators (2) . Gleichzeitig dient der Körper (1) auch zur Führung und ■ mit der angebrachten Sicke (3) sowie den Blechzungen(4) zur Arretierung im Bereich zwischen Abgasflansch (6) und Zylinderkopf (7) in Verbindung mit der dazugehörigen Dichtung (8).Der vordere Teil der Katalysatorpatrone ragt dabei in den Zylinderkopf (7) hinein.Das konisch ausgebildete Ausströmteil (5) ist bei dieser Ausführung rundherum mit Austrittslöchern versehen.In the following, the invention is explained in more detail with reference to drawings showing only one embodiment. It shows Figure 1 the basic structure according to the invention of the catalytic converter cartridge in perspective - Vischer representation.The round body (1) made of heat-resistant steel is used to accommodate the catalytic converter (2). At the same time, the body (1) also serves as a guide and ■ with the attached bead (3) and the sheet metal tongues (4) for locking in the area between the exhaust flange (6) and cylinder head (7) in conjunction with the associated seal (8). The front part of the catalyst cartridge protrudes into the cylinder head (7). The conical In this version, the outflow part (5) is provided with outlet holes all around.
