Abstract
Description
Die Erfindung betrifft ein Diesel-Kraftstofffilter nach dem Oberbegriff des Patentanspruchs 1.The The invention relates to a diesel fuel filter according to the preamble of claim 1
Werden Diesel-Kraftstofffilter mit einem Biodiesel-Kraftstoff beaufschlagt, kann es im Vergleich zu einer Beaufschlagung mit einem Nicht-Biodiesel-Kraftstoff zu einer frühzeitigen Filterverstopfung kommen.Become Diesel fuel filter charged with a biodiesel fuel, it can in Compared to exposure to a non-biodiesel fuel to an early age Filter clogging come.
Der Grund für eine solche frühzeitige Verstopfung sind Ablagerungen, die sich insbesondere nach einem Einfüllen in den Tank eines Kraftfahrzeuges bilden können. Derartige Ablagerungen besitzen eine Größe und Struktur, durch die diese Ablagerungen sich an der Oberfläche eines Kraftstofffilters absetzen. Hier bilden die Ablagerungen eine differenzdruckerhöhende Schicht, die bereits nach äußerst kurzen Betriebszeiten das Filter derart verstopfen kann, dass kein einwandfreier bis gar kein Motorbetrieb mehr wegen Kraftstoffmangels möglich ist.Of the reason for such an early one Constipation are deposits, especially after a pour in can form into the tank of a motor vehicle. Such deposits have a size and structure, through which these deposits attach themselves to the surface of a fuel filter drop. Here, the deposits form a differential pressure-increasing layer, which already after extremely short Operating times can clog the filter so that no flawless until no more engine operation is possible because of fuel shortage.
Die Erfindung beschäftigt sich mit dem Problem, hier auf eine möglichst einfache und sicher wirkende Weise Abhilfe zu schaffen.The Invention busy deal with the problem, here on a simple and safe effective way to remedy the situation.
Gelöst wird dieses Problem alternativ oder in Kombination durch Ausführungen gattungsgemäßer Diesel-Kraftstofffilter nach den Merkmalen der Ansprüche 1 und 3.Is solved this problem alternatively or in combination by executions generic diesel fuel filter according to the features of the claims 1 and 3.
Vorteilhafte und zweckmäßige Ausgestaltungen sind jeweils Gegenstand von Unteransprüchen.advantageous and appropriate embodiments are each the subject of dependent claims.
Die Erfindung beruht auf dem allgemeinen Gedanken, die Ablagerungen, die auf der Filteroberfläche eine relativ leicht lösbare Schicht darstellen, als Schicht kontinuierlich oder diskontinuierlich abzulösen und aus dem Filter zu entsorgen. Die Entsorgung kann dann insbesondere zusammen mit einer Entsorgung abgeschiedenen Wassers erfolgen und zwar in einer Weise, wie bisher in einem Diesel-Kraftstofffilter abgeschiedenes Wasser aus dem Filter abgeführt wird.The Invention is based on the general idea, the deposits, the on the filter surface a relatively easy to solve Layer, as a layer continuously or discontinuously replace and discard from the filter. The disposal can then in particular taken together with a disposal of separated water and that in a way as previously deposited in a diesel fuel filter Water drained from the filter becomes.
Um eine oberflächlich angesammelte Ablagerungsschicht möglichst einfach ablösen zu können, ist es besonders vorteilhaft, eine möglichst glatte, gegebenenfalls auch noch hydrophob wirkende Oberfläche an dem zu durchströmenden Filtermaterial zu erzeugen. Konkret kann eine solche Oberfläche durch das Aufziehen eines dünnen Filtersiebes erreicht werden. Dieses Filtersieb besitzt in diesem Fall eine geringere Filterfeinheit als das erste Filtermaterial. Diese äußere Filtermaterialschicht beziehungsweise Oberfläche muss ledig lich eine solche Feinheit und möglichst keine größere haben, dass die sich in einem Biodiesel bildenden Ablagerungen gerade noch derart auf der Oberfläche verbleiben, dass sie von dieser einfach abgetrennt werden können.Around a superficial to be able to easily detach accumulated deposit layer is It is particularly advantageous to have one as possible smooth, possibly also hydrophobic surface acting on the to flow through To produce filter material. Specifically, such a surface can through putting on a thin one Filter screen can be achieved. This filter has in this Case a lower filter fineness than the first filter material. This outer filter material layer or surface must have only such fineness and preferably no larger, that the deposits forming in a biodiesel are just barely like that on the surface remain that they can easily be separated from this.
Das Abtrennen kann beispielsweise dadurch gefördert werden, dass bei einer besonders vorteilhaften Ausgestaltung eines gattungsgemäßen Filters eine Kraftstoffzuführung durch entsprechende konstruktive Mittel realisiert wird, durch die der zu filternde Kraftstoff radial und/oder tangential auf einen kleinen Bereich der Filtermaterialoberfläche gebündelt aufgebracht wird. Hierdurch lässt sich eine Auftreffenergie des Kraftstoffes in diesem Auftreffbereich erreichen, die verhindert, dass zumindest in dem Auftreffbereich verstopfend wirkende Dieselablagerungen sich ansammeln können. Auch, wenn möglicherweise die Bildung einer Ablagerungsschicht in außerhalb des Auftreffbereiches liegenden Bereichen des Filtermaterials nicht oder nicht vollständig vermieden werden kann, so bleibt doch zumindest immer noch durch die offene Auftrefffläche bedingt ein Notbetrieb des Filters erhalten, das heißt es wird zumindest ein Motorstillstand durch vollständig fehlende Kraftstoffzufuhr auf diese Weise sicher vermieden. Ein solcher Notbetrieb fällt dem Fahrer auf und er kann dann zumindest den Motor- sowie einen eingeschränkten Fahrbetrieb bis zu einer Filterreinigung beziehungsweise einem Filterwechsel in einer Werkstatt aufrechterhalten.The Separation can be promoted, for example, that at a Particularly advantageous embodiment of a generic filter a Fuel supply is realized by appropriate constructive means by the the fuel to be filtered radially and / or tangentially to a small area of the filter material surface is applied bundled. hereby let yourself an impact energy of the fuel in this impact area Achieve that prevents at least in the impact area Clogging diesel deposits can accumulate. Also, if possible the formation of a deposit layer outside the impact area lying areas of the filter material is not or not completely avoided can, at least still remains due to the open landing area an emergency operation of the filter obtained, that is, it is at least a motor stall through completely Missing fuel supply safely avoided in this way. One such emergency operation falls the driver and he can then at least the engine and a limited driving up to a filter cleaning or a filter change maintained in a workshop.
Besonders vorteilhaft ist eine erfindungsgemäße Ausführung, bei der eine filterverstopfende Ablagerungsschicht durch ein Rückspülen des Kraftstofffilters abgetragen und durch den Wasserablass des Kraftstofffilters entsorgt werden kann. Konstruktiv reicht es im Grunde bereits aus, für einen solchen Rückspülbetrieb ein Umschaltventil und gegebenenfalls eine Förderpumpe in der den Kraftstoff dem Motor zuführenden Leitung vorzusehen. Allein hierdurch ist es nämlich möglich, Kraftstoff rückspülend durch das Filterelement zu führen.Especially Advantageous is an embodiment according to the invention, in which a Filterverstopfende Depositing layer by backwashing the Fuel filter removed and through the water drain of the fuel filter can be disposed of. In terms of construction, it is basically enough for one such backwash operation a switching valve and optionally a feed pump in the fuel feeding the engine Provide line. This alone makes it possible to flush the fuel back through the fuel To lead filter element.
Vorteilhafte und zweckmäßige, nachstehend noch näher erläuterte Ausführungsbeispiele sind in der Zeichnung dargestellt.advantageous and appropriate, below closer explained embodiments are shown in the drawing.
