Die Erfindung betrifft eine Kraftstofffördereinrichtung für eine Kraftstoffeinspritzeinrichtung einer Brennkraftmaschine und ein Verfahren zur Reduzierung des Druckes im Vorratsbehälter einer Kraftstofffördereinrichtung nach dem Oberbegriff des unabhängigen Anspruches 1.The invention relates to a fuel delivery device for a fuel injection device of an internal combustion engine and a method for reducing the pressure in the reservoir of a fuel delivery device according to the preamble of

Der Erfindung liegt die Aufgabe zugrunde, ein gasbetriebenes Fahrzeug anzugeben, das eine verbesserte Kraftstofffördereinrichtung zur Reduzierung des Druckes im Vorratsbehälter einer Kraftstofffördereinrichtung aufweist.The invention is based on the object of specifying a gas-powered vehicle which has an improved fuel delivery device for reducing the pressure in the reservoir of a fuel delivery device.
Offenbarung der ErfindungDisclosure of the invention
Vorteile der ErfindungAdvantages of the invention
Die erfindungsgemäße Kraftstofffördereinrichtung mit den Merkmalen gemäß Anspruch 1 hat den Vorteil, dass der Druck im Vorratsbehälter reduziert werden kann und dabei die im Kraftstoff vorhandenen Energie zum Antrieb der einer Einrichtung zur Umwandlung von Kraftstoff in Kälteenergie genutzt werden kann.The fuel delivery device according to the invention with the features according to
Im kälteisolierten Vorratsbehälter (z.B. LNG-Tank, Kryo-Tank) wird der gasförmige Kraftstoff bei einer Temperatur von -140°C gespeichert. Aufgrund der niedrigen Temperaturen befindet sich der Kraftstoff in der flüssigen Phase. Für den motorischen Betrieb sind aber deutlich höhere Temperaturen nötig (ca. -20°C). Durch einen Wärmeeintrag von außen, beispielsweise durch Sonneneinstrahlung, oder durch erwärmten Kraftstoff, welcher durch die Rücklaufleitung zurück in den Vorratsbehälter strömt, kann sich die Temperatur des Kraftstoffes im Vorratsbehälter erhöhen.The gaseous fuel is stored at a temperature of -140 ° C in the cold-insulated storage container (e.g. LNG tank, cryo tank). Due to the low temperatures, the fuel is in the liquid phase. However, significantly higher temperatures are required for motor operation (approx. -20 ° C). The temperature of the fuel in the storage container can increase as a result of heat input from the outside, for example due to solar radiation, or due to heated fuel which flows through the return line back into the storage container.
Der Kraftstoff im Vorratsbehälter kann aufgrund des Wärmeeintrages eine Änderung des Aggregatszustandes erfahren, so dass sich ein Teil des Kraftstoffes von der flüssigen in die gasförmige Phase umwandelt, welches einen Druckanstieg im Vorratsbehälter bedingt.The fuel in the reservoir can experience a change in the state of the aggregate due to the heat input, so that part of the fuel converts from the liquid to the gaseous phase, which causes a pressure increase in the reservoir.
Durch die Vorrichtung zur Umwandlung von Kraftstoff in Kälteenergie kann Kraftstoff aus dem Vorratsbehälter entweichen und zum Antrieb einer Kältemaschine genutzt werden. Auf diese Weise geht die Energie, die sich im Kraftstoff befindet nicht ungenutzt, beispielsweise durch ein Ausströmen in die Umwelt, verloren.The device for converting fuel into cooling energy allows fuel to escape from the storage container and be used to drive a cooling machine. In this way, the energy in the fuel is not wasted, for example due to an outflow into the environment.
In den abhängigen Ansprüchen sind vorteilhafte Ausgestaltungen und Weiterbildungen der erfindungsgemäßen Vorrichtung angegeben.Advantageous refinements and developments of the device according to the invention are specified in the dependent claims.
Es ist von Vorteil, wenn die Vorrichtung zur Umwandlung von Kraftstoff in Kälteenergie eine Absorptionskältemaschine aufweist, da diese einen besonders hohen Wirkungsgrad hat.It is advantageous if the device for converting fuel into cooling energy has an absorption refrigerator, since this has a particularly high efficiency.
Ein Anschluss, der im oberen Bereich des Vorratsbehälters angeordnet ist, ist vorteilhaft, um sicherzustellen, dass vornehmlich Kraftstoff in der gasförmigen Phase aus dem Vorratsbehälter entweicht. Durch eine Entnahme das Kraftstoffes in der gasförmigen Phase wird das Selbstkühlpotential des Vorratsbehälters erhöht.A connection, which is arranged in the upper region of the storage container, is advantageous in order to ensure that primarily fuel escapes from the storage container in the gaseous phase. Removing the fuel in the gaseous phase increases the self-cooling potential of the storage container.
Ein weiterer Vorteil ergibt sich durch ein Druckregelventil, welches in der Abströmleitung angeordnet ist, da die Menge an Kraftstoff, welche aus dem Vorratsbehälter strömt exakt und auf einfache Weise gesteuert werden kann.A further advantage results from a pressure control valve which is arranged in the outflow line, since the amount of fuel which flows out of the storage container can be controlled precisely and in a simple manner.
Ein in der Abströmleitung angeordneter Wärmetauscher ist vorteilhaft, da über diesen der aus dem Vorratsbehälter entnommene Kraftstoff erwärmt werden kann, so, dass er die für die Vorrichtung zur Umwandlung von Kraftstoff in Kälteenergie benötigte Betriebstemperatur annehmen kann.A heat exchanger arranged in the outflow line is advantageous because it can be used to heat the fuel removed from the storage container so that it can assume the operating temperature required for the device for converting fuel into cooling energy.
Es ist von Vorteil, wenn durch die Vorrichtung zur Umwandlung von Kraftstoff in Kälteenergie eine Fahrzeugkabine kühlbar ist, da diese durch überschüssigen Kraftstoff, also Kraftstoff welcher ansonsten ungenutzt abgegeben würde, angetrieben wird. Dies führt zu einer Reduzierung des gesamten Kraftstoffverbrauches im Kraftfahrzeug, da der Kraftstoffverbrauch der Nebenaggregate sinkt.It is advantageous if a vehicle cabin can be cooled by the device for converting fuel into cooling energy, since it is driven by excess fuel, that is to say fuel which would otherwise be emitted unused. This leads to a reduction in the total fuel consumption in the motor vehicle, since the fuel consumption of the auxiliary units decreases.
