Description

Es ist jedem Autofahrer bekannt, daß im Stau bzw. hinter einem Dieselfahr­ zeug die vom Ventilator angesaugte Frischluft zu einer echten Belästigung führen kann. Es handelt sich dabei weniger um die bekannten Schadstoffe wie z. B. CO, NO x , sondern vielmehr um unvollständig verbrannte Treibstoffrück­ stände.It is known to every driver that in a traffic jam or behind a diesel vehicle, the fresh air drawn in by the fan can lead to real annoyance. It is less about the known pollutants such. B. CO, NO x , but rather would stand around incompletely burned fuel back.

Andererseits beschreibt das EP 01 00 907 einen Weg, um die die Geruchsbe­ lästigung verursachenden Verbindungen aus der angesaugten Luft mit flexiblen Flächenfiltern, deren Aktivkohle frei zugängig ist herauszufiltern. Eine bevorzugte Ausführung besteht aus einem hochporösen Träger - insbesondere ein großporiger, retikulierter PU-Schaum - an welchem mittels einer Haftmas­ se Aktivkohleteilchen zum Haften gebracht sind. Daß es bis heute noch keine serienmäßige Anwendungen gibt, hat folgenden Grund: Die Fachwelt vertrat die Meinung, daß der Filter für viele Jahre (100 000 km) ausreichen muß und daß mehrere Filterschichten nötig wären. Das wiederum verlangte eine so große Menge Aktivkohle, daß die Filterlagen nur in einem relativ großen Behälter unterzubringen sind. Der Platz hierfür ist aber in keinem Pkw vorhanden, so daß ein Nachrüsten nicht möglich schien. Neue Modelle werden Jahre vor ihrem Erscheinen geplant und wenn der Platz für einen solchen Filterkasten nicht vorgesehen war, ist es auch in diesem Fall sehr schwierig, ihn unterzubrin­ gen.On the other hand, EP 01 00 907 describes a way to filter out the compounds causing the odor nuisance from the intake air with flexible surface filters, the activated carbon of which is freely accessible. A preferred embodiment consists of a highly porous carrier - in particular a large-pored, reticulated PU foam - to which activated carbon particles are adhered by means of an adhesive mass. The reason for the fact that there are still no series applications is as follows: The experts believed that the filter had to last for many years (100,000 km) and that several filter layers would be necessary. This in turn required such a large amount of activated carbon that the filter layers can only be accommodated in a relatively large container. The space for this is not available in any car, so that retrofitting did not seem possible. New models are planned years before their release and if the space for such a filter box was not provided, it is very difficult to accommodate it even in this case.

Es wurde nun überraschenderweise gefunden, daß auch einschichtige Filter mit einer Fläche von weniger als 100 cm2 die erwähnte Geruchsbelästi­ gung so gut wie vollständig beseitigen und das obschon bei voller Ventila­ torleistung und dem kleinen Querschnitt hohe Strömungsgeschwindigkeiten auf­ treten. Dieser unerwartete Befund macht es nun möglich, Filter mit minimalem Platzbedarf einzubauen, so daß einer Nachrüstung im allgemeinen nichts mehr im Wege steht. Aufgrund der notgedrungen niedrigen Menge Aktivkohle ist die Lebensdauer des Filters verkürzt. So wurden beispielsweise bei einem Filter­ block von 80×80×18 mm der in die Frischluftzufuhr eines Opel Kadett (Baujahr 1987) eingebaut wurde und ca. 17 g einer kugelförmigen Aktivkohle (⌀≈0,5 mm) nach 3 Monaten erste Durchbrüche registriert. It has now surprisingly been found that even single-layer filters with an area of less than 100 cm 2 eliminate the above-mentioned odor nuisance almost completely and that, although with full ventila tor performance and small cross-section, high flow velocities occur. This unexpected finding now makes it possible to install filters with a minimal space requirement, so that in general nothing stands in the way of retrofitting. Due to the inevitable low amount of activated carbon, the life of the filter is shortened. For example, with a filter block of 80 × 80 × 18 mm which was installed in the fresh air supply of an Opel Kadett (year of construction 1987) and approx. 17 g of a spherical activated carbon (⌀≈0.5 mm) first breakthroughs were registered after 3 months.

Der erfindungsgemäße Kleinfilter ist deshalb auf einfachste Weise aus­ wechselbar: das Filtermaterial (z. B. der beladene PU-Schaum) befindet sich in einer kleinen "Kassette", einem Kunststoffrahmen mit Führungsschiene, der sich über eine Öffnung in den zu filternden Luftstrom einschieben läßt. Übermäßige Verschmutzung der Aktivkohle (Staub ....) kann durch einen eben­ falls auswechselbaren Vorfilter vermieden werden. Der Rauminhalt der kom­ pletten Kassette beträgt 50-1000 ml vorzugsweise 100-500 ml, wobei die Filterschicht eine Dicke von 10-80 mm vorzugsweise 15-50 mm aufweist.The small filter according to the invention is therefore in the simplest way changeable: the filter material (e.g. the loaded PU foam) is located in a small "cassette", a plastic frame with a guide rail, the can be inserted through an opening in the air flow to be filtered. Excessive contamination of the activated carbon (dust ....) can be caused by a if replaceable pre-filters are avoided. The volume of the com plette cassette is 50-1000 ml, preferably 100-500 ml, the Filter layer has a thickness of 10-80 mm, preferably 15-50 mm.
