Abstract
Description
Die Erfindung betrifft ein Kraftstofftank-System für ein Kraftfahrzeug, insbe sondere einen Personenkraftwagen, mit mehr als einem Kraftstoff- Vorratsbehälter. Zum technischen Umfeld wird beispielshalber auf die DE 32 25 351 A1 sowie auf die DE 198 13 574 A1 verwiesen.The invention relates to a fuel tank system for a motor vehicle, in particular especially a passenger car with more than one fuel Storage container. For technical reasons, reference is made to the DE 32 25 351 A1 and DE 198 13 574 A1.
Üblicherweise besitzen Personenkraftwagen (PKWs) einen einzigen mehr oder weniger großen Kraftstofftank, der seitens des PKW-Herstellers zumeist derart dimensioniert ist, daß sich bei durchschnittlichem Kraftstoffverbrauch mit diesem Kraftfahrzeug eine akzeptable Reichweite, gemessen von einem Betankungsvorgang zum nächsten, ergibt. Insbesondere um ein uner wünschtes Liegenbleiben des PKW's wegen übersehenem Nachbetanken zu vermeiden, sind ferner Reserve-Kraftstoffbehälter bekannt (vgl. die eingangs erstgenannte Schrift), die ortsfest bspw. oberhalb des eigentlichen Kraft stofftanks im Fahrzeug eingebaut sind. Weiterer bekannter Stand der Tech nik, nämlich bspw. nach der eingangs zweitgenannten Schrift, sind Kraftstoff- Kartuschen, die im geleerten Zustand ausgetauscht, d. h. durch volle Kartu schen ersetzt werden, jedoch kommen diese bislang nur bei tragbaren Ar beitsmaschinen, bspw. an einer von einer Brennkraftmaschine angetriebe nen Sense oder dgl. zum Einsatz. Passenger cars (cars) usually have one more or less large fuel tank, which is usually from the car manufacturer is dimensioned such that with average fuel consumption with this motor vehicle an acceptable range, measured by one Refueling process to the next, results. In particular, an un Desired parking of the car due to overlooked refueling to avoid, reserve fuel tanks are also known (see first-mentioned font), which is stationary, for example, above the actual force cloth tanks are installed in the vehicle. Another known state of the art nik, namely, for example, according to the above-mentioned document, fuel Cartridges replaced when empty, d. H. through full carto be replaced, but so far these have only come with portable ar Beitsmaschinen, for example on a driven by an internal combustion engine a scythe or the like.
Zurückkommend zu PKWs bzw. Kraftfahrzeugen ist mit der bislang üblichen starren Ausführung des Kraftstoff-Vorratsbehälters dessen Fassungsvolu men und somit die Reichweite des Fahrzeuges nicht an das jeweilige Anfor derungsprofil des Fahrzeugführers anpaßbar. Beispielsweise sind sog. Viel fahrer bzw. Langstreckenfahrer, die lediglich einen geringen Bedarf an Kof ferraum-Volumen haben, trotz des somit grundsätzlich noch freien Staurau mes zu häufigen Tankstops mit entsprechendem Zeitverlust gezwungen, während sog. Wenigfahrer häufig eine zu große Kraftstoff-Vorratsmenge und somit ein unnötig hohes Gewicht im PKW mitführen.Coming back to cars or motor vehicles is the usual one so far rigid version of the fuel storage tank its volume and therefore the range of the vehicle does not meet the respective requirements the driver's profile can be adjusted. For example, so-called drivers or long-distance drivers who only need a small amount of luggage volume, despite the basically still free storage space forced to frequent refueling stops with a corresponding loss of time, while so-called infrequent drivers often have too much fuel and thus carry an unnecessarily high weight in the car.
Eine Abhilfemaßnahme für diese geschilderte Problematik aufzuzeigen, ist Aufgabe der vorliegenden Erfindung.A remedial measure for these problems is to be shown Object of the present invention.
Die Lösung dieser Aufgabe ist dadurch gekennzeichnet, daß eine variable Anzahl von Kraftstoff-Kartuschen in zumindest einem vom Passagierraum getrennten Hohlraum im Kraftfahrzeug unterbringbar und von da aus gas dicht mit der Kraftstoffversorgungsanlage der das Kraftfahrzeug antreiben den Brennkraftmaschine verbindbar ist. Vorteilhafte Weiterbildungen sind Inhalt der Unteransprüche.The solution to this problem is characterized in that a variable Number of fuel cartridges in at least one of the passenger compartment separate cavity in the motor vehicle and gas from there tightly with the fuel supply system of the motor vehicle the internal combustion engine is connectable. Advantageous further developments are Content of the subclaims.
Hier wird der Einsatz eines Behältersystemes vorgeschlagen, das dem Fah rer bzw. Fahrzeugführer eine bestmögliche Anpassung des mitgeführten Kraftstoffvolumens an die jeweils gewünschte Fahrstrecke (Distanz) erlaubt. Dieses vorgeschlagene System lehnt sich dabei in gewisser Weise an die bekannten Kartuschensysteme (vgl. o. g. DE 198 13 574 A1) an, unterschei det sich davon jedoch insofern, als mehrere Kartuschen in variabler Anzahl unterbringbar und gleichzeitig gasdicht letztendlich mit der Kraftstoffversor gungsanlage der Fahrzeug-Brennkraftmaschine verbindbar sind. Dies be deutet, daß die erste geleerte Kartusche nicht sofort ausgetauscht werden muß, sondern daß das Kraftfahrzeug solange weiterbewegt werden kann, bis alle vorhandenen Kartuschen vollständig geleert sind. Here the use of a container system is proposed, which the Fah rer or vehicle driver the best possible adjustment of the carried Fuel volume allowed to the desired route (distance). This proposed system is somewhat based on the known cartridge systems (see above DE 198 13 574 A1), different However, this differs in that several cartridges in variable numbers can be accommodated and at the same time gastight ultimately with the fuel supply supply system of the vehicle internal combustion engine can be connected. This be indicates that the first empty cartridge will not be replaced immediately must, but that the motor vehicle can be moved as long as until all existing cartridges are completely empty.
Insbesondere unterscheidet sich das vorgeschlagene System vom bekann ten Stand der Technik aber durch die Flexibilität. Vollkommen variabel bzw. an seinen Bedarf angepaßt kann der Fahrer bestimmen, wie viele mit Kraft stoff gefüllte Kartuschen er für eine bestimmte Fahrtstrecke innerhalb der gesetzlich zulässigen Höchstgrenzen mitnehmen möchte. Dabei können auch Kartuschen unterschiedlichen Volumens zum Einsatz kommen, so bspw. mit einem Fassungsvolumen von 10 Litern oder 20 Litern oder sogar 50 Litern.In particular, the proposed system differs from the known one state of the art through flexibility. Completely variable or Adapted to his needs, the driver can determine how many with power cartridges filled with fabric for a certain distance within the want to take legally permissible maximum limits with them. You can cartridges of different volumes are also used, so For example, with a volume of 10 liters or 20 liters or even 50 liters.
Aus Sicherheitsgründen wesentlich ist, daß diese Kartuschen in einem vom Fahrzeug-Innenraum getrennten Hohlraum des PKW's untergebracht wer den, so bspw. im Kofferraum oder in einem anderen, bevorzugt vom Koffer raum aus zugänglichen Hohlraum, wobei die allgemein gültigen bzw. übli chen Sicherheitsvorschriften selbstverständlich einzuhalten sind. Bei gerin gem Zuladungsbedarf kann dann das Kofferraumvolumen zum Transport von zusätzlichem Kraftstoff in Kartuschen verwendet werden. In diesem Zu sammenhang sei darauf hingewiesen, daß das vorgeschlagene Kartuschen- System insbesondere als Zusatz-System zu einem üblichen, weiterhin vor handenen Kraftstoff-Vorratsbehälter verwendet werden kann. Dann ist es besonders vorteilhaft, wenn die Kartuschen entweder über Gravitation oder mittels einer eigenen Pumpe in den im wesentlichen üblichen Kraftstoff- Vorratsbehälter entleerbar sind.For security reasons it is essential that these cartridges in one of Vehicle interior separate cavity of the car who housed that, for example in the trunk or in another, preferably from the suitcase space from accessible cavity, whereby the generally applicable or usual Chen safety regulations are of course to be observed. At low The trunk volume can then be transported according to the load requirement of additional fuel to be used in cartridges. In this To context it should be noted that the proposed cartridge System in particular as an additional system to a usual one, before existing fuel reservoir can be used. Then it is particularly advantageous if the cartridges are either gravitational or by means of its own pump in the essentially usual fuel Storage containers can be emptied.
Grundsätzlich können die Kartuschen derart gestaltet sein, daß sie von je dermann im Kraftfahrzeug einsetzbar sind, wobei dann an den bereits ge nannten gasdichten Anschluß an die vorhandene Kraftstoffversorgungsanla ge hohe Anforderungen gestellt werden. Daher kann auch vorgesehen sein, daß die Kartusche(n) nur von autorisiertem Fachpersonal in einer Werkstatt oder an einer Tankstelle einsetzbar sind. Dabei können die Kartuschen als Einweg-Kartuschen (mit Pfandsystem) oder als wiederbefüllbare Behälter (bspw. aus Aluminium oder Kunststoff) ausgebildet sein.Basically, the cartridges can be designed such that they each dermann can be used in the motor vehicle, in which case the ge named gas-tight connection to the existing fuel supply system high demands are made. It can therefore also be provided that the cartridge (s) only by authorized specialist personnel in a workshop or can be used at a petrol station. The cartridges can be used as Disposable cartridges (with deposit system) or as refillable containers (for example made of aluminum or plastic).
Grundsätzlich können die Kartuschen vergleichbar den Kraftstoff- Reservebehältern an Tankstellen befüllt werden, wobei im Hinblick auf eine besonders komfortable und einfach Befüllung leere, im Kraftfahrzeug ange ordnete Kartuschen auch vom üblichen Kraftstoff-Vorratsbehälter desselben aus befüllbar sein können, und zwar unter Zuhilfenahme der üblicherweise im Vorratsbehälter angeordneten Elektro-Kraftstoffpumpe.Basically, the cartridges can be compared to the fuel Reserve containers are filled at petrol stations, taking into account a particularly convenient and easy filling empty, in the motor vehicle also arranged cartridges from the usual fuel storage container of the same can be filled from, with the help of the usual Electric fuel pump arranged in the reservoir.
Durch den Einsatz des vorgeschlagenen Systems kann das im Kraftfahrzeug mitgeführte Kraftstoff-Fassungsvolumen bestmöglich an die beabsichtigte Fahrleistung (Distanz) angepaßt werden. Zusätzlich kann dadurch die Wahr scheinlichkeit des Liegenbleibens wegen fehlendem Kraftstoff in unsicheren Gebieten bzw. in Gebieten mit unzureichender Infrastruktur verringert wer den.By using the proposed system, this can be done in the motor vehicle carried fuel volume as best as possible to the intended Mileage (distance) can be adjusted. In addition, the truth Probability of getting stuck in unsafe due to lack of fuel Areas or areas with insufficient infrastructure the.
