Abstract
Description
Die Erfindung betrifft eine Kraftfahrzeugvorrichtung nach dem Oberbegriff des Anspruchs 1.The invention relates to a motor vehicle device according to the preamble of claim 1.
Aus der
Der Erfindung liegt insbesondere die Aufgabe zugrunde, eine kostengünstige Kraftfahrzeugvorrichtung mit einer verbesserten motorunabhängigen Regenerierung des Adsorptionsfilters bereitzustellen. Sie wird gemäß der Erfindung durch die Merkmale des Anspruchs 1 gelöst. Weitere Ausgestaltungen ergeben sich aus den Unteransprüchen.The invention is in particular the object of providing a cost motor vehicle device with an improved engine-independent regeneration of the adsorption filter. It is achieved according to the invention by the features of claim 1. Further embodiments emerge from the subclaims.
Die Erfindung geht aus von einer Kraftfahrzeugvorrichtung mit einer Kraftstoffvorrichtung, die zumindest ein Adsorptionsfilter aufweist, das dazu vorgesehen ist, zumindest teilweise ein Kraftstoffgas aufzunehmen, und mit einer Kältemaschine, die wenigstens einen Warmteil und einen Kaltteil aufweist und zumindest teilweise zur Temperierung von wenigstens einem Teil der Kraftstoffvorrichtung vorgesehen ist.The invention is based on a motor vehicle device having a fuel device which has at least one adsorption filter which is provided to at least partially receive a fuel gas and with a refrigeration machine which has at least one hot part and one cold part and at least partially for the temperature control of at least one part the fuel device is provided.
Es wird vorgeschlagen, dass der Warmteil der Kältemaschine zumindest zur Erwärmung des Adsorptionsfilters vorgesehen ist. Dadurch kann eine schon vorhandene Wärme zur Erwärmung des Adsorptionsfilters und damit eines Adsorbermaterials des Adsorptionsfilters genutzt werden, wodurch eine Regenerierung und damit ein Herausspülen des Kraftstoffgases aus dem Adsorptionsfilter verbessert werden kann. Durch die Nutzung der durch die Kältemaschine bereitgestellten Wärme können Kosten, Bauraum und Komplexität der Kraftfahrzeugvorrichtung reduziert werden. Unter einem „Adsorptionsfilter” soll insbesondere ein Filter verstanden werden, das zumindest ein Adsorptionsmittel aufweist, das zur Aufnahme und/oder Filterung von Kohlenwasserstoffen eines Kraftstoffgases vorgesehen ist. Unter einem „Kraftstoffgas” soll insbesondere ein gasförmiges Gemisch aus Luft und Kraftstoff verstanden werden, das aufgrund einer Verdunstung und/oder eines Ausdampfens des Kraftstoffs in einem Kraftstofftank eines die Kraftfahrzeugvorrichtung aufweisenden Kraftfahrzeugs entsteht. Unter einem „Kraftstoff” soll insbesondere ein flüssiger Kraftstoff, wie insbesondere Benzin oder Diesel, verstanden werden, der zum Bereitstellen einer Antriebskraft direkt in einer Brennkraftmaschine des Kraftfahrzeugs verbrannt wird. Unter einer „Temperierung” soll insbesondere eine Veränderung einer Temperatur verstanden werden, bei der die Temperatur erhöht oder verringert wird. Unter einem „Warmteil” soll insbesondere ein Teil der Kältemaschine verstanden werden, der im Vergleich zu dem Kaltteil der Kältemaschine eine höhere Temperatur aufweist. Unter einer „Regenerierung” soll insbesondere ein Vorgang verstanden werden, in dem das Kraftstoffgas und/oder Kraftstoffbestandteile aus dem Adsorptionsfilter entfernt und/oder gelöst werden. Die Kraftfahrzeugvorrichtung ist insbesondere für ein Kraftfahrzeug vorgesehen, das zumindest eine Brennkraftmaschine aufweist. Grundsätzlich kann die Kraftfahrzeugvorrichtung auch für ein Hybridkraftfahrzeug vorgesehen werden, das zumindest eine Brennkraftmaschine und zumindest einen Elektromotor aufweist. Unter „vorgesehen” soll insbesondere speziell programmiert, ausgelegt und/oder ausgestattet verstanden werden.It is proposed that the hot part of the refrigerator is provided at least for heating the adsorption filter. As a result, an already existing heat can be used for heating the adsorption filter and thus an adsorber material of the adsorption filter, as a result of which regeneration and thus flushing out of the fuel gas from the adsorption filter can be improved. By utilizing the heat provided by the chiller, the cost, space and complexity of the automotive device can be reduced. An "adsorption filter" should in particular be understood to mean a filter which has at least one adsorption agent which is provided for receiving and / or filtering hydrocarbons of a fuel gas. A "fuel gas" is to be understood in particular a gaseous mixture of air and fuel, which arises due to evaporation and / or evaporation of the fuel in a fuel tank of a motor vehicle device having motor vehicle. A "fuel" is to be understood in particular a liquid fuel, such as in particular gasoline or diesel, which is burned to provide a driving force directly in an internal combustion engine of the motor vehicle. A "tempering" is to be understood in particular as meaning a change in a temperature at which the temperature is increased or decreased. A "hot part" is to be understood in particular a part of the refrigerator, which has a higher temperature compared to the cold part of the refrigerator. A "regeneration" is to be understood in particular a process in which the fuel gas and / or fuel components are removed from the adsorption and / or dissolved. The motor vehicle device is provided in particular for a motor vehicle which has at least one internal combustion engine. In principle, the motor vehicle device can also be provided for a hybrid motor vehicle which has at least one internal combustion engine and at least one electric motor. By "provided" is intended to be understood in particular specially programmed, designed and / or equipped.
Weiter wird vorgeschlagen, dass die Kraftstoffvorrichtung zumindest einen an den Kaltteil der Kältemaschine angebundenen Kondensator aufweist, der dazu vorgesehen ist, zumindest das von dem Adsorptionsfilter aufgenommene Kraftstoffgas zu verflüssigen. Dadurch kann durch ein Regenerieren des Adsorptionsfilters das aufgenommene Kraftstoffgas kondensiert und in den Kraftstofftank zurückgeführt werden, wodurch eine Kraftstoffeinsparung erhöht werden kann.It is further proposed that the fuel device has at least one connected to the cold part of the refrigerator condenser, which is intended to liquefy at least the fuel gas received by the adsorption filter. Thereby, by regenerating the adsorption filter, the absorbed fuel gas can be condensed and returned to the fuel tank, whereby fuel economy can be increased.
Außerdem wird vorgeschlagen, dass die Kraftstoffvorrichtung zumindest einen Regenerierungskreislauf aufweist, der dazu vorgesehen ist, das Kraftstoffgas zumindest durch das Adsorptionsfilter und den Kondensator zu führen. Dadurch kann das aus dem Adsorptionsfilter herausgespülte Kraftstoffgas besonders einfach verflüssigt werden.It is also proposed that the fuel device has at least one regeneration circuit which is provided to guide the fuel gas at least through the adsorption filter and the condenser. As a result, the fuel gas purged out of the adsorption filter can be liquefied particularly easily.

Die Zeichnung, die Beschreibung und die Ansprüche enthalten zahlreiche Merkmale in Kombination. Der Fachmann wird die Merkmale zweckmäßigerweise auch einzeln betrachten und zu sinnvollen weiteren Kombinationen zusammenfassen.Further advantages emerge from the following description of the drawing.
