Abstract

The fuel is supplied via pipes from the liquid phase or the gas phase of the fuel, to the engine. The feed pressure is generated by evaporating liquid fuel. The pressure is used to extract fuel from the gas phase of the tank (2) via a throttle (6). The pressure drop at the throttle causes fuel feed from the liquid phase into the fuel supply system (7). The cryogenic fuel contains mainly hydrogen or methane. The throttle is a suction jet pump. The tank system has a rising pipe (8) for liquid fuel and a gas pipe (5), both without valves. Both pipes extend from the vehicle tank into the fuel system. The gas pipe contains a throttle.

Description

Die Erfindung betrifft ein Verfahren zur Versorgung eines Fahrzeugmotors mit kryo­ genem Kraftstoff aus einem isolierten Kraftstofftank, wobei der Kraftstoff über eine Steigleitung aus der Flüssigphase oder über eine Leitung aus der Gasphase des Kraft­ stofftanks gefördert und über einen Kraftstoffversorgungsstrang dem Fahrzeugmotor zugeführt wird, wobei der Förderdruck durch Verdampfen von flüssigem Kraftstoff erzeugt wird.The invention relates to a method for supplying a vehicle engine with kryo genem fuel from an insulated fuel tank, the fuel via a Riser line from the liquid phase or via a line from the gas phase of the force fueled tanks and the vehicle engine via a fuel supply line is supplied, the delivery pressure by vaporization of liquid fuel is produced.

Aus der Veröffentlichung: H. Rüdiger "Design characteristics and performance of a liquid hydrogen tank system for motor cars" Cryogenics (1992) Vol. 32, No. 3, Seiten 327 bis 329, ist ein Tanksystem nach dem Oberbegriff des Anspruchs 1 bekannt. Dort werden für die Kraftstoffentnahme aus dem Kraftstofftank drei Ventile und zwei Rück­ schlagklappen benötigt. Dies erfordert einen großen apparativen Aufwand, da die genannten Armaturen (V2, V3, V4, V6 und V7 in Fig. 1 der o. g. Veröffentlichung) vakuumisoliert untergebracht werden müssen.From the publication: H. Rüdiger "Design characteristics and performance of a liquid hydrogen tank system for motor cars" Cryogenics (1992) Vol. 32, No. 3, pages 327 to 329, a tank system according to the preamble of claim 1 is known. There, three valves and two non-return flaps are required to remove fuel from the fuel tank. This requires a large outlay on equipment, since the fittings mentioned (V2, V3, V4, V6 and V7 in FIG. 1 of the above-mentioned publication) have to be accommodated in a vacuum-insulated manner.

Aufgabe der Erfindung ist es deshalb, das Tanksystem zu vereinfachen.The object of the invention is therefore to simplify the tank system.

Diese Aufgabe wird erfindungsgemäß gelöst von einem Verfahren mit den Merkmalen des Anspruchs 1. Ausführungen der Erfindung sind Gegenstand von Unteransprüchen.According to the invention, this object is achieved by a method having the features of claim 1. Embodiments of the invention are the subject of dependent claims.

Kennzeichnend an der Erfindung ist, daß mit Hilfe des Förderdruckes über eine Dros­ sel Kraftstoff aus der Gasphase des Kraftstofftanks entnommen wird und durch den an der Drossel erzeugten Druckabfall die Förderung aus der Flüssigphase des Kraftstoff­ tanks in den Kraftstoffversorgungsstrang bewirkt wird.Characteristic of the invention is that with the help of the delivery pressure via a Dros sel fuel is taken from the gas phase of the fuel tank and by the the throttle pressure drop generated the promotion from the liquid phase of the fuel tanks in the fuel supply line is effected.

Die nach dem Stand der Technik benötigten Ventile entfallen. Benötigt wird statt des­ sen eine Drossel, die im Isolierraum des Kraftstofftanks fest eingebaut werden kann, da sie einen geringen Platzbedarf hat und keine bewegten Teile enthält, also keine Wartung oder Reparatur erfordert. The valves required according to the prior art are eliminated. What is needed instead of a throttle that can be permanently installed in the fuel tank insulation since it takes up little space and contains no moving parts, so none Maintenance or repair required.  

Der kryogene Kraftstoff kann überwiegend Wasserstoff oder überwiegend Methan enthalten.The cryogenic fuel can predominantly be hydrogen or predominantly methane contain.

Mit Hilfe einer als Saugstrahlpumpe ausgeführten Drossel kann Kraftstoff aus der Gas­ phase verwendet werden, um Flüssigtreibstoff in die Kraftstoffleitung zu pumpen.With the help of a throttle designed as a suction jet pump, fuel can be extracted from the gas phase can be used to pump liquid fuel into the fuel line.

Bei der Tankvorrichtung für das erfindungsgemäße Verfahren mit einem Fahrzeugtank, mit einer Steigleitung für flüssigen Treibstoff und mit einer Gasleitung können beide Leitungen ventilfrei ausgeführt sein und aus dem Fahrzeugtank in den Kraftstoff­ versorgungsstrang münden, und die Gasleitung kann eine Drossel enthalten.In the tank device for the method according to the invention with a vehicle tank, both with a liquid fuel riser and with a gas pipe Lines are valve-free and run from the vehicle tank into the fuel supply line open, and the gas line may contain a throttle.

Die Erfindung wird anhand einer Ausführungsform mit einer Figur näher erläutert. Die Figur zeigt ein erfindungsgemäßes Verfahren zur Versorgung eines Fahrzeug­ motors mit kryogenem Kraftstoff.The invention is explained in more detail using an embodiment with a figure. The figure shows an inventive method for supplying a vehicle engines with cryogenic fuel.

Die Figur zeigt schematisch eine Ausführung des erfindungsgemäßen Verfahrens ein­ gebettet in ein Tanksystem, das eine Leitung 1 zur Befüllung eines Fahrzeugtanks 2 mit flüssigem Kraftstoff und eine Leitung 3 zur Gasrückführung während des Befüllens aufweist.The figure shows schematically an embodiment of the method according to the invention embedded in a tank system which has a line 1 for filling a vehicle tank 2 with liquid fuel and a line 3 for gas recirculation during filling.

Zum Versorgen eines Fahrzeugmotors mit kryogenem Kraftstoff aus dem Fahrzeug­ tank 2 wird mit einem Heizer 4 flüssiger Kraftstoff verdampft. Dadurch wird eine Druck­ erhöhung im Fahrzeugtank 2 erzielt und gasförmiger Kraftstoff durch die Gasleitung 5 über eine Drossel 6 in den Kraftstoffversorgungsstrang 7 geführt. Bei Erreichen eines ausreichend großen Massenstromes durch die Gasleitung 5 wird der Druckabfall an der Drossel so groß, daß über eine Steigleitung 8 flüssiger Kraftstoff in den Kraftstoff­ versorgungsstrang 7 in Richtung Motor gefördert wird. Der zur Flüssigförderung benö­ tigte Tankinnendruck wird mit dem Heizer 4 geregelt. Vorgesehen ist auch eine Druck­ absenkung vor dem Parken, oder wenn nach längerem Parken aufgrund des Wärme­ stromes durch die Tankisolierung hindurch ein erhöhter Tankinnendruck herrscht.To supply a vehicle engine with cryogenic fuel from the vehicle tank 2 , liquid fuel is evaporated using a heater 4 . As a result, a pressure increase is achieved in the vehicle tank 2 and gaseous fuel is passed through the gas line 5 via a throttle 6 into the fuel supply line 7 . When a sufficiently large mass flow through the gas line 5 is reached, the pressure drop across the throttle is so great that liquid fuel is conveyed into the fuel supply line 7 in the direction of the engine via a riser 8 . The tank pressure required for liquid delivery is regulated by the heater 4 . A pressure drop is also provided before parking, or if there is an increased internal pressure in the tank after long periods of parking due to the heat flow through the tank insulation.
