Abstract
Description
Die Erfindung betrifft ein Verfahren zum Betrieb einer Verbrennungskraftmaschine, insbesondere eines Dieselmotors, bei dem ein Kraftstofffilter mittels eines in diesem angeordneten Heizelements erwärmt wird.The Invention relates to a method for operating an internal combustion engine, in particular a diesel engine, in which a fuel filter by means of is heated in this arranged heating element.
Es ist bekannt, dass bei niedrigen Temperaturen, insbesondere im Minusbereich, Dieselkraftstoff aufgrund des in diesem enthaltenen Paraffins dazu neigt, zu stocken, wodurch ein Kraftstofffilter verstopfen und der Dieselkraftstoff in dessen Verlauf, insbesondere vom Kraftstofftank zum Motor den Kraftstofffilter nicht durchfließen kann. Darüber hinaus ist bekannt, dass der Dieselkraftstoff Wasseranteile enthält, die beispielsweise durch Kondensation im Tankbehälter und/oder in Tankleitungen hervorgerufen wird.It it is known that at low temperatures, especially in the minus range, Diesel fuel due to the paraffin contained in it tends to falter, causing a fuel filter clogging and the Diesel fuel in its course, especially from the fuel tank to the engine can not flow through the fuel filter. In addition, it is known that the diesel fuel water shares Contains, for example, by condensation in the tank and / or caused in tank lines.

Der Erfindung liegt die Aufgabe zugrunde, ein verbessertes Verfahren sowie eine verbesserte Vorrichtung zum Betrieb einer Verbrennungskraftmaschine, insbesondere eines Dieselmotors anzugeben, welche einfach und kostengünstig realisierbar sind.Of the Invention is based on the object, an improved method and an improved device for operating an internal combustion engine, Specify in particular a diesel engine, which is simple and inexpensive are feasible.
Die Aufgabe wird hinsichtlich des Verfahrens erfindungsgemäß durch die in Anspruch 1 und hinsichtlich der Vorrichtung durch die in Anspruch 4 angegebenen Merkmale gelöst. Vorteilhafte Weiterbildungen der Erfindung sind Gegenstand der Unteransprüche.The Task is according to the invention in terms of the method that in claim 1 and in terms of the device by the in Claim 4 specified features solved. Advantageous developments The invention are the subject of the dependent claims.
Bei dem erfindungsgemäßen Verfahren zum Betrieb einer Verbrennungskraftmaschine, insbesondere eines Dieselmotors, wird ein Kraftstofffilter mittels eines in diesem angeordneten Heizelements erwärmt. Erfindungsgemäß wird das Heizelement von einem Glühsteuergerät zum Vorglühen von Glühkerzen temperaturabhängig gesteuert. Dabei wird dem Heizelement über das Glühsteuergerät elektrische Energie zugeführt. Besonders bevorzugt wird aufgrund der Kopplung des Heizelements an das Glühsteuergerät eine aufwändige Verkabelung zur Versorgung des Heizelements mit elektrischer Energie vermieden. Darüber hinaus wird anhand dieser Kopplung eine vereinfachte Diagnosefähigkeit des Heizelements erreicht, woraus ein verringerter Wartungs- bzw. Reparaturaufwand resultiert.at the inventive method for operating a Internal combustion engine, in particular a diesel engine, is a fuel filter by means of a heating element arranged in this heated. According to the invention, the heating element from an annealing control unit for preheating Controlled by glow plugs temperature dependent. there is the heating element via the annealing control unit electrical energy supplied. Particularly preferred due to the coupling of the heating element to the annealing control device an elaborate wiring for the supply of the heating element avoided with electrical energy. In addition, will based on this coupling a simplified diagnostic capability of the heating element, resulting in a reduced maintenance or Repair expenses result.
