Description
Die Erfindung betrifft eine Diesel-Kraftstoffilter-Einrichtung eines Kraftfahrzeug-Verbrennungsmotors nach dem Oberbegriff des Patentanspruchs 1.The The invention relates to a diesel fuel filter device of a motor vehicle internal combustion engine according to the preamble of claim 1.
Aus
der
Gattungsgemäße Diesel-Kraftstoffiltereinrichtungen dienen dazu, bei niedrigen Temperaturen, bei denen aus dem Kraftstoff ausgefallene Feststoffe, insbesondere Paraffine, den Strömungswiderstand des Filters derart erhöhen, dass für den Verbrennungsmotor keine ausreichende Kraftstoffversorgung gegeben ist, die Ablagerungen durch ein Vorwärmen des Kraftstoffes zu vermeiden bzw. aufzulösen, wenn solche Ablagerungen bereits erfolgt sind. In Fällen, in denen ein Kraftstoffilter ein relativ großes Filtervolumen besitzt, kann das Wirksamwerden vorgewärmten Kraftstoffes eine für eine einwandfreie Motorfunktion zu große Zeitdauer einnehmen.Generic diesel fuel filter devices Serve at low temperatures, where from the fuel precipitated solids, especially paraffins, the flow resistance of To increase filters in such a way that for the internal combustion engine is not given sufficient fuel supply is to avoid the deposits by preheating the fuel or dissolve, if such deposits have already occurred. In cases, in where a fuel filter has a relatively large filter volume, can be preheated to take effect Fuel one for to assume a perfect motor function for a long period of time.
Hier mit technisch einfachen und energiesparend wirkenden Mitteln eine Verbesserung zu schaffen, stellt das Problem dar, mit dem sich die Erfindung beschäftigt und das sie bei einer Ausführung der gattungsgemäßen Einrichtung nach dem kennzeichnenden Merkmal des Patentanspruchs 1 löst.Here with technically simple and energy-saving means a To create improvement is the problem with which the Invention busy and that in an execution of the generic device solves the characterizing feature of claim 1.
Zweckmäßige Ausgestaltungen sind Gegenstand der Unteransprüche.Advantageous embodiments are the subject of the dependent claims.
Die Erfindung beruht auf dem allgemeinen Gedanken, eine Kraftstoffvorwärmung nur dann vorzunehmen, wenn bei niedrigen Temperaturen ein derart erhöhter Strömungswiderstand in dem Kraftstoffilter vorliegt, daß in dem Kraftstoff stromauf des Hauptfilters ein das Überdruckventil in der Umgehungsleitung öffnender Druck herrscht. Dabei öffnet das Überdruckventil bestimmungsgemäß erst bei einem vorgegebenen oberen Grenzwert, bei dessen überschreiten eine einwandfreie und sichere Motorfunktion mit Bezug auf die Auslegung des Motors als nicht mehr gewährleistet angesehen wird.The Invention is based on the general idea, a fuel preheating only then, if at low temperatures such increased flow resistance is present in the fuel filter that in the fuel upstream of the main filter on the pressure relief valve opening in the bypass Pressure prevails. This opens the pressure relief valve as intended only at a predetermined upper limit, which exceeds a flawless and safe engine function with respect to the design of the engine as no longer guaranteed is seen.
Die erfindungsgemäße Einrichtung arbeitet derart, daß bei geöffnetem Überdruckventil die Heizung nur dann eingeschaltet wird, wenn gleichzeitig die Temperatur in dem durch das Kraftstoffilter zu fördernden Kraftstoff unterhalb eines vorgegebenen unteren Grenzwertes liegt. Ist dieser Temperaturgrenzwert bei dem Kraftstoff stromauf des Kraftstoffilters nicht gegeben, wird von einer nicht temperaturbedingten Betriebsstörung des Kraftstoffilters durch beispielsweise normale Verschmutzung, das heißt von einer betriebsbedingten Erschöpfung ausgegangen, wobei durch das Öffnen des Überdruckventiles ein entsprechendes Wartungssignal erzeugt wird.The inventive device works in such a way that at opened pressure relief valve the heater is only turned on when the temperature is at the same time in the fuel to be delivered through the fuel filter below a predetermined lower limit. Is this temperature limit not given in the fuel upstream of the fuel filter, is caused by a non - thermal malfunction of the Fuel filter by example, normal pollution, the is called assumed from an operational fatigue, by the opening the pressure relief valve a corresponding maintenance signal is generated.
Das Zusatzfilter in der Umgehungsleitung besitzt gegenüber dem Hauptfilter ein erheblich geringeres Filtervolumen, das heißt insbesondere Filterfläche, damit vorgewärmter Kraftstoff möglichst rasch das gesamte Zusatzfilter auf eine zur Vermeidung temperaturbedingter Kraftstoffablagerungen ausreichend hohe Temperatur erwärmen kann. Hilfreich kann insoweit auch ein geringerer Abscheidegrad des Filtermaterials des Zusatzfilters gegenüber demjenigen des Hauptfilters sein. Dabei muß aber darauf geachtet werden, daß der Abscheidegrad nicht über ein Maß hinaus abgesenkt wird, durch das die Einspritzung gefährdende Verunreinigungen in dem Zusatzfilter nicht ausreichend abgeschieden werden.The Additional filter in the bypass line has over the Main filter a significantly lower filter volume, ie in particular Filter area so preheated Fuel as soon as possible the entire additional filter on one to avoid temperature Fuel deposits can heat sufficiently high temperature. Helpful in this respect, a lower degree of separation of the filter material the additional filter over that be the main filter. But it must be on it be respected that the Degree of separation not over a measure beyond is lowered, by the injection of hazardous contaminants in the Additional filters are not adequately deposited.
