Abstract

The filter, for removing soot particles in the exhaust gas from a vehicle internal combustion motor, is an add-on fitting inserted into the end of the normal exhaust pipe. The filter has a flat and rectangular box shape (1), with stems (3) at the interior (2). They are placed alternately, at intervals (5), to form a cascade flow path through the filter in the gaps between their ends and the housing. Filter inserts (4) are in tightly-fitting packets of steel wool, coated steel wool, fine steel wool or mineral wool.

Description

Der hier vorgestellte Russ Partikelfilter hat eine flache Form (1), also keinen allgemein üblichen runden oder ovalen Querschnitt wie die normalen Auspufftöpfe. Der Vorteil gegenüber den bekannten Partikelfiltern ist, dass sie bedarfsgerecht gereinigt bzw. Filterpakete ausgewechselt werden können, während bei den bekannten Filtern die Entfernung des ausgefilterten Rußes größere Schwierigkeiten bereitet, etwa durch Verbrennung des angesammelten Rußes.The soot particle filter presented here has a flat shape ( 1 ), not a generally round or oval cross-section like the normal mufflers. The advantage over the known particle filters is that they can be cleaned as required or filter packs can be replaced, while the removal of the soot that is filtered out causes greater difficulties in the known filters, for example by burning the soot that has accumulated.

Der Filterkasten (1) hat eine Öffnung an der Langseite, die mit einem Deckel, mit einer Klappe oder einem Schieber dicht verschließbar ist. Diese flache Form ist gewählt, weil sie z.B. platzsparend unter einem Wagen montiert werden kann. Die flache Form erlaubt durch Öffnung des seitlichen Deckels (bzw. Klappe oder Schieber) den Zugang zur Innenseite. (2)The filter box ( 1 ) has an opening on the long side, which can be sealed with a lid, a flap or a slide. This flat shape is chosen because it can be installed under a cart to save space. The flat shape allows access to the inside by opening the side cover (or flap or slide). ( 2 )

Die Innenseite des Filterkörpers ist ausgestattet mit Stegen (3), die in bestimmten (berechneten) Abständen den Boden und die Decke des Filterkörpers verbinden, also entweder eingenietet oder eingeschweißt sind. Die Stege haben nicht die Länge der Behältertiefe, sondern sind gekürzt bis auf eine Lücke in der Breite der Stegabstände (5). Sie werden abwechselnd so eingebracht, dass ein Kaskadenweg für die Auspuffgase entsteht.The inside of the filter body is equipped with webs ( 3 ), which connect the floor and ceiling of the filter body at certain (calculated) intervals, i.e. either riveted or welded in. The webs do not have the length of the container depth, but are shortened to a gap in the width of the web spacings ( 5 ). They are introduced alternately so that a cascade path for the exhaust gases is created.

Die Formgebung der Stege ist derart, dass Filterpakete eingeschoben werden können (3).The shape of the webs is such that filter packs can be inserted ( 3 ).

Die aus Stahlwolle, beschichtete Stahlwolle, aus Edelstahlwolle, aus Mineralwolle, oder auch aus einem Gemisch von Stahlwolle und Mineralwolle bestehenden Filterpakete werden passgenau hergestellt. (4)The steel wool, coated Steel wool, stainless steel wool, mineral wool, or even one Mixture of steel wool and mineral wool existing filter packs are made to measure. (4)

Die im Kasten eingeschweißten oder eingenieteten Stege dienen auch zur Stabilisierung der Form des Kastens. Die Stege sind so gestaltet, dass die zu filternden Gase nicht nur durch die Gänge, sondern auch durch die Filterpakete gezwungen werden und so als Filter wirksam werden.The welded in the box or Riveted webs also serve to stabilize the shape of the Box. The webs are designed so that the gases to be filtered not just through the aisles, but can also be forced through the filter packs and thus effective as a filter become.

Die Staffelung der Stege mit den Filtern im Filterkasten ist derart, dass das Volumen des Auspuffrohres in einem anderen Querschnitt (den Kaskaden) Platz hat, aber eher enger eingestellt ist. Die Gase werden dann kaskadenartig durch das Filtergehäuse und durch die Filterpakete geführt, ohne dem laufenden Motor einen zu starkem Widerstand entgegen zu setzen.The staggering of the bridges with the Filtering in the filter box is such that the volume of the exhaust pipe in a different cross-section (the cascades), but rather is set closer. The gases are then cascaded through the filter housing and passed through the filter packs, without too much resistance to the running engine put.

Die Größe der Filtergehäuse, die Anzahl der einzubauenden Stege und Filterpakete, sowie die benötigten Abstände im Gehäuse sind zu berechnen und dem jeweiligen Motor anzupassen.The size of the filter housing that Number of bars and filter packs to be installed, as well as the required distances in the housing to be calculated and adapted to the respective engine.

Der Filterkasten und die Stege sind normalerweise aus Stahlblech und verzinkt. Sie können aber ebenso aus Edelstahl hergestellt werden. Zusätzlich kann der Filterkasten aber auch innenbeschichtet werden mit einem Antihaftmittel, wie z.B. Teflon, wie es in Küchengeräten verwendet wird. Die Reinigung wird dadurch erleichtert.The filter box and the webs are usually made of sheet steel and galvanized. But they can also be made of stainless steel getting produced. additionally the filter box can also be coated on the inside with a Non-stick agents such as Teflon as used in kitchen appliances. The cleaning this will make it easier.

Dieser Russ Partikelfilter ist gedacht als Aufsatzfilter auf normale Endauspufftöpfe. Ein flexibler Anschluss Schlauch stellt die Verbindung zwischen Endtopf und Russ Partikelfilter her. Der Russ Partikelfilter ist in der beschriebenen Konfiguration quer unter dem Wagen eingebaut und dem Fahrtwind ausgesetzt. Diese Kühlung bewirkt zusätzlich die Ausfällung der auszufilternden Russ Partikel.This soot particle filter is thought as a top filter on normal mufflers. A flexible connection Hose connects the silencer to the soot particle filter forth. The soot particle filter is in the configuration described installed transversely under the car and exposed to the wind. This cooling causes additional the precipitation of the soot particles to be filtered out.

Eine Zurücksetzung des Endtopfes bzw. eine leichte Veränderung der Konstruktion der Auspuffanlage erleichtert die Anbringung des Russ Partikelfilters.A reset of the silencer or a slight change the construction of the exhaust system makes it easier to attach the Russ particulate filter.

Der Russ Partikelfilter ist mit allen geschilderten Vorzügen veränder- und erweiterbar und als solcher dann auch als End- Auspufftopf zu verwenden.The soot particulate filter is with everyone described advantages changeability and expandable and can be used as a muffler.

In dieser Konstruktion kann die Querschnittsform auch rund oder oval sein. Das Innere würde sich entsprechend ändern lassen. Die Reinigung dieser runden Konstruktion würde durch Auszug der Filterpakete nach hinten erfolgen müssen.In this construction, the cross-sectional shape also be round or oval. The interior could be changed accordingly. This round construction would be cleaned by pulling out the filter packs must be done to the rear.

Der Hauptnutzen des Russ Partikelfilters ist darin zu sehen, dass er die Russ Partikel, die bisher mit den normalen Auspuff Töpfen nicht abgefiltert werden konnten, fast restlos aus den Abgasen entfernt, ohne dem Motor unakzeptablen Widerstand entgegen zu setzen.The main benefit of the soot particulate filter can be seen in the fact that it contains the soot particles that were previously used with the normal exhaust pots could not be filtered, almost completely removed from the exhaust gases, without providing unacceptable resistance to the motor.

Der noch größere Vorteil des Russ Partikelfilters ist zu sehen darin, dass die Filterpakete zur Reinigung oder zur Auswechslung herausnehmbar sind. Die Reinigung kann mit Staubsauger, durch Rüttelung, durch Ausblasen, durch Auswaschen oder Verbinden dieser Methoden erfolgen.The even greater advantage of the soot particle filter can be seen in the fact that the filter packs for cleaning or Replacement are removable. Cleaning can be done with a vacuum cleaner, by shaking, by blowing out, washing out or combining these methods respectively.

Eine weitere Reinigungsmöglichkeit wäre gegeben durch Rüttelung des Russ Partikelfilters am Wagen und den Abzug des Rußes am Boden des Filterkastens durch einige mit einem Schieber zu öffnende und zu schließende Öffnungen.Another cleaning option would be given by shaking of the soot particle filter on the car and the extraction of the soot on the floor of the filter box by some opening with a slide and openings to close.
