Description
Die vorliegende Erfindung betrifft ein Kraftfahrzeug, insbesondere ein Personenkraftwagen, mit den Merkmalen des Oberbegriffs des Anspruchs 1.The present invention relates to a motor vehicle, in particular a passenger car, having the features of the preamble of
Üblicherweise weist ein Kraftfahrzeug eine Brennkraftmaschine auf, die mit einem flüssigen Kraftstoff betrieben werden kann. Aus verschiedenen Gründen kann ein derartiges Fahrzeug mit einem Reformer ausgestattet sein, mit dessen Hilfe aus einem flüssigen Kraftstoff ein Wasserstoffgas enthaltendes Reformatgas generiert werden kann. Ein derartiges Reformatgas kann beispielsweise der Brennkraftmaschine zur Verbrennung zugeführt werden. Ebenso kann derartiges Reformatgas in einer Brennstoffzelle zum Generieren von elektrischem Strom umgesetzt werden. Ebenso ist es möglich, mit Hilfe von Reformatgas eine Heizeinrichtung des Fahrzeugs zu betreiben.Usually, a motor vehicle has an internal combustion engine that can be operated with a liquid fuel. For various reasons, such a vehicle may be equipped with a reformer, by means of which a hydrogen gas containing reformate gas can be generated from a liquid fuel. Such a reformate gas can for example be supplied to the internal combustion engine for combustion. Likewise, such reformate gas may be reacted in a fuel cell to generate electric power. It is also possible to operate a heating device of the vehicle with the aid of reformate gas.
Bei Reformern, die in einem Kraftfahrzeug zum Einsatz kommen, z. B. als Bestandteil eines Brennstoffzellensystems, bietet es sich an, den im Fahrzeug zum Betreiben einer Brennkraftmaschine ohnehin mitgeführten Kraftstoff zum Herstellen des Wasserstoffgas enthaltenden Reformatgases zu verwenden. Beispielsweise eignen sich ohne Beschränkung der Allgemeinheit Benzin, Diesel, Erdgas und Biodiesel zur Verwendung in einem Reformer. Bei flüssigen Kraftstoffen lässt sich häufig eine inhomogene Gemischbildung zwischen dem verdampften Kraftstoff und dem gasförmigen Oxidator, in der Regel Luft, beobachten.In reformers who are used in a motor vehicle, for. B. as part of a fuel cell system, it makes sense to use the already carried in the vehicle for operating an internal combustion engine fuel for producing the hydrogen gas containing reformate gas. For example, without limitation, gasoline, diesel, natural gas, and biodiesel are suitable for use in a reformer. With liquid fuels, an inhomogeneous mixture formation between the vaporized fuel and the gaseous oxidizer, usually air, can often be observed.

Die vorliegende Erfindung beschäftigt sich mit dem Problem, für ein mit einem Reformer ausgestattetes Kraftfahrzeug eine verbesserte Ausführungsform anzugeben, die sich insbesondere durch eine homogene Gemischbildung im Reformer auszeichnet.The present invention addresses the problem of providing an improved embodiment for a motor vehicle equipped with a reformer, which is characterized in particular by a homogeneous mixture formation in the reformer.
Dieses Problem wird erfindungsgemäß durch die Gegenstände der unabhängigen Ansprüche gelöst. Vorteilhafte Ausführungsformen sind Gegenstand der abhängigen Ansprüche.This problem is solved according to the invention by the subject matters of the independent claims. Advantageous embodiments are the subject of the dependent claims.
Die vorliegende Erfindung beruht auf dem allgemeinen Gedanken, eine zum Antreiben des Kraftstoffs zum Reformer vorgesehene Reformer-Fördereinrichtung unmittelbar in einem Kraftstofftank anzuordnen und eine vom Kraftstofftank zum Reformer führende Reformer-Kraftstoffleitung an die Reformer-Fördereinrichtung anzuschließen. Auf diese Weise kann die Saugseite der Reformer-Fördereinrichtung auf direktem Weg, ohne große Saugstrecke Kraftstoff aus dem Kraftstofftank ansaugen. Die Vermeidung einer langen Saugstrecke an der Saugseite der Reformer-Fördereinrichtung hat zur Folge, dass die Neigung zur Blasenbildung im Kraftstoff signifikant reduziert ist.The present invention is based on the general idea of arranging a reformer conveyor provided for driving the fuel to the reformer directly in a fuel tank and connecting a reformer fuel line leading from the fuel tank to the reformer to the reformer conveyor. In this way, the suction side of the reformer conveyor on a direct path, suck in fuel from the fuel tank without a large suction path. The avoidance of a long suction line on the suction side of Reformer conveyor has the consequence that the tendency to form bubbles in the fuel is significantly reduced.
Die Erfindung nutzt hierbei die Erkenntnis, dass Blasen im flüssigen Kraftstoff die homogene Gemischbildung behindern.The invention uses the knowledge that bubbles in the liquid fuel hinder the homogeneous mixture formation.
Es hat sich gezeigt, dass die Vermeidung von Blasen im Kraftstoff zu einer gleichmäßigeren Förderleistung der Reformer-Fördereinrichtung und somit zu einer gleichmäßigeren Einleitung von Kraftstoff in den Reformer führt, was insgesamt eine kontinuierliche Verdampfung und die Ausbildung eines homogenen Gemischs begünstigt.It has been found that the avoidance of bubbles in the fuel leads to a more uniform flow rate of the reformer conveyor and thus to a more uniform introduction of fuel into the reformer, which favors overall continuous evaporation and the formation of a homogeneous mixture.
Die Erfindung ist von besonderem Interesse, wenn es sich beim verwendeten flüssigen Kraftstoff um einen vergleichsweise flüchtigen Kraftstoff, also um einen Kraftstoff mit vergleichsweise niedriger Verdampfungstemperatur handelt, wie z. B. Benzin.The invention is of particular interest when the liquid fuel used is a comparatively volatile fuel, that is to say a fuel with a comparatively low vaporization temperature, such as e.g. Gasoline.
Bei der Erfindung ist im Kraftstofftank außerdem eine Motor-Fördereinrichtung vorgesehen, mit deren Hilfe die Brennkraftmaschine mit dem Kraftstoff aus dem Kraftstofftank versorgt werden kann. Hierzu ist eine vom Kraftstofftank zur Brennkraftmaschine führende Motor-Kraftstoffleitung direkt an die Motor-Fördereinrichtung angeschlossen. Durch die Bereitstellung eines gemeinsamen Kraftstofftanks sowohl für die Brennkraftmaschine als auch für den Reformer, kann der Bauraumbedarf für die Kraftstoffversorgung des Reformers reduziert werden.In the invention, a motor conveyor is also provided in the fuel tank, with the aid of which the internal combustion engine can be supplied with the fuel from the fuel tank. For this purpose, a leading from the fuel tank to the engine engine fuel line is connected directly to the motor conveyor. By providing a common fuel tank for both the engine and the reformer, the space requirement for the fuel supply of the reformer can be reduced.
Erfindungsgemäß ist die Reformer-Fördereinrichtung in einem Reformer-Schwalltopf angeordnet, der hierzu im Kraftstofftank vorgesehen ist. Auf entsprechende Weise ist auch ein Motor-Schwalltopf im Kraftstofftank vorgesehen, in dem die Motor-Fördereinrichtung angeordnet ist. Die beiden Schwalltöpfe sind nun erfindungsgemäß so aufeinander abgestimmt, dass bei abnehmendem Kraftstofffüllstand eine kommunizierende Verbindung zwischen dem Reformer-Schwalltopf und dem Kraftstofftank ab einem vorbestimmten Schwellwert unterbrochen wird, während eine kommunizierende Verbindung zwischen dem Motor-Schwalltopf und dem Kraftstofftank weiterhin bestehen bleibt. Hierdurch wird erreicht, dass bei sinkendem Kraftstofffüllstand der im Kraftstofftank verbleibende Kraftstoff nicht mehr dem Reformer zur Verfügung steht. Hierdurch wird eine Priorisierung dahingehend erreicht, dass bei abnehmendem Kraftstofffüllstand gegebenenfalls der Reformerbetrieb eingestellt wird, bevor die Brennkraftmaschine nicht mehr betrieben werden kann.According to the invention, the reformer conveyor is arranged in a reformer swirl pot, which is provided for this purpose in the fuel tank. In a corresponding manner, a motor swirl pot is provided in the fuel tank, in which the engine conveyor is arranged. The two baffles are now according to the invention coordinated so that at decreasing fuel level a communicating connection between the reformer baffle and the fuel tank is interrupted from a predetermined threshold, while a communicating connection between the engine baffle and the fuel tank continues to exist. This ensures that with decreasing fuel level of the remaining fuel in the fuel tank is no longer available to the reformer. As a result, a prioritization is achieved to the effect that with decreasing fuel level, if necessary, the reformer operation is set before the internal combustion engine can no longer be operated.
Weitere wichtige Merkmale und Vorteile der Erfindung ergeben sich aus den Unteransprüchen, aus den Zeichnungen und aus der zugehörigen Figurenbeschreibung anhand der Zeichnungen.Other important features and advantages of the invention will become apparent from the dependent claims, from the drawings and from the associated figure description with reference to the drawings.
Es versteht sich, dass die vorstehend genannten und die nachstehend noch zu erläuternden Merkmale nicht nur in der jeweils angegebenen Kombination, sondern auch in anderen Kombinationen oder in Alleinstellung verwendbar sind, ohne den Rahmen der vorliegenden Erfindung zu verlassen.It is understood that the features mentioned above and those yet to be explained below can be used not only in the particular combination given, but also in other combinations or in isolation, without departing from the scope of the present invention.
