Dies erfolgt beispielsweise dadurch, dass die Trennung von Kraftstoff und Schmiermittel als Filterung durchgeführt wird.This takes place, for example, by separating fuel and lubricant is carried out as filtering.
Dabei ist vorgesehen, dass der Filter in einem Filtergehäuse angeordnet wird. Der Filter ist dabei so in dem Filtergehäuse angeordnet, dass sich der Kraftstoff in dem Filtergehäuse sammelt und vorzugsweise mit dem Filtergehäuse entsorgt werden kann. Dabei kann in dem Filtergehäuse ein weiterer Schmierstofffilter, beispielsweise ein konventioneller Partikelfilter, angeordnet werden.there it is provided that the filter is arranged in a filter housing becomes. The filter is arranged in the filter housing so that the Fuel in the filter housing collects and can preferably be disposed of with the filter housing. there can in the filter housing another lubricant filter, for example a conventional particle filter, to be ordered.
Als weiterer Schmierstofffilter kann auch ein Kleinstpartikelfilter verwendet werden, der in einem Nebenstrom des Schmiermittelkreislaufes angeordnet wird.As A small particle filter can also be used for additional lubricant filters be used in a bypass flow of the lubricant circuit is arranged.
In einer vorteilhaften Weiterbildung der Erfindung ist vorgesehen, dass das Schmiermittel zur Trennung von dem Kraftstoff mit Druck durch den Filter gepresst wird. Dieser Druck kann beispielsweise von einer Schmiermittelpumpe erzeugt werden, wobei das Filtergehäuse direkt nach einer Schmiermittelpumpe in dem Schmiermittelkreislauf angeordnet wird. Alternativ oder zusätzlich kann der Druck von einer Zentrifuge erzeugt werden, durch welche die Filterung gemäß der spezifischen Dichte des Kraftstoffes und des Schmierstoffes erfolgt.In An advantageous development of the invention is provided that the lubricant to separate from the fuel with pressure is pressed through the filter. This pressure can be, for example, from a lubricant pump are generated, the filter housing directly is arranged after a lubricant pump in the lubricant circuit. Alternatively or additionally the pressure can be generated by a centrifuge through which filtering according to the specific Density of the fuel and the lubricant takes place.
Als Filtermaterialien kommen alle Stoff in Frage, die beispielsweise Diesel als Kraftstoff und Motoröl als Schmiermittel voneinander trennen können.As Filter materials can be any substance, for example Diesel as fuel and engine oil can separate from each other as a lubricant.
Ein derartiges Filtermaterial ist beispielsweise eine semipermeable Membran, die nur die kürzeren Kohlenwasserstoffketten des Dieselkraftstoffes hindurchlässt, während sie die längeren Kohlenwasserstoffketten des Motoröls zurückhält.On such filter material is, for example, a semipermeable Membrane that only the shorter Lets hydrocarbon chains of diesel fuel pass through while they the longer ones Retains hydrocarbon chains in the engine oil.
Zu diesen Stoffen gehören ebenfalls Bindemittel, die Diesel an sich binden, Motoröl jedoch eher abweisen.To belong to these substances also binders that bind diesel, but motor oil rather reject.
Eine Trennung von Schmiermittel und Kraftstoff kann ebenfalls chemisch durch eine katalytische Reaktion herbeigeführt werden.A Separation of lubricant and fuel can also be chemical can be brought about by a catalytic reaction.
Eine katalytische Reaktion erfolgt in einem Reaktor, der im Schmiermittelkreislauf der Brennkraftmaschine angeordnet wird. Dabei wird das die katalytische Reaktion herbeiführende Material auf eine für die katalytische Reaktion geeignete Temperatur erhitzt, wobei die Zersetzungstemperatur beispielsweise des Motoröls nicht erreicht werden darf. Dieses Erhitzen kann vorteilhaft elektrisch durchgeführt werden. Vor den Reaktor wird vorteilhaft ein Partikelfilter angeordnet.A Catalytic reaction takes place in a reactor in the lubricant circuit the internal combustion engine is arranged. This will be the catalytic one Reaction-inducing Material on a for the catalytic reaction is heated to a suitable temperature, the The decomposition temperature of the engine oil, for example, must not be reached. This Heating can advantageously be carried out electrically. In front of the reactor a particle filter is advantageously arranged.
Bei der katalytischen Reaktion des Kraftstoffes werden Reaktionsprodukte gebildet, die aus dem Schmiermittelkreislauf herausgeführt und beispielsweise der Abgasanlage der Brennkraftmaschine zugeführt werden.at The catalytic reaction of the fuel becomes reaction products formed, which led out of the lubricant circuit and For example, the exhaust system of the internal combustion engine are supplied.
Das die katalytische Reaktion herbeiführende Material wird von einem Edelmetall gebildet, das auf einem eine große Oberfläche aufweisenden Trägermaterial aufgebracht wird.The the catalytic reaction-inducing material is from a Precious metal formed on a substrate with a large surface is applied.
Durch das erfindungsgemäße Verfahren wird beim Betrieb der Brennkraftmaschine eine Beeinträchtigung der Schmiereigenschaften des Schmierstoffes durch eine zu hohe Kraftstoffkonzentration im Schmiermittelkreislauf vermieden.By the inventive method becomes an impairment in the operation of the internal combustion engine the lubricating properties of the lubricant due to an excessive fuel concentration avoided in the lubricant circuit.
Im folgenden ist das Verfahren zum Betreiben einer einen Schmiermittelkreislauf aufweisenden Brennkraftmaschine anhand von zwei Ausführungsbeispielen im Zusammenhang mit zwei Figuren dargestellt und erläutert.The following is the method for operating an internal combustion engine having a lubricant circuit using two embodiments examples shown and explained in connection with two figures.
