Abstract

A vehicle fuel tank reserve supply lay-out has a small central compartment (4) set over the fuel outlet and closed to the top by a non return outlet valve (6). The compartment retains fuel until the level in the rest of the tank sinks below the bottom edge of the compartment wall. A level indicator (8) in the compartment provides warning of low fuel. The device can be applied to any type of tank, with the compartment filled to the same level as the rest of the tank during normall filling, by allowing air to be vented through the non eturn valve. The indicator shows the driver than he has a set amount of fuel left. The device is unaffected by tilting of the vehicle.

Description

Integrierter' Zusatztank zum Kraftstofftank für Kraftfahrzeuge Die normalerweise sehr flache Ausführung von Kraftstoffbehältern von Kraftfahrzeugen - insbesondere von Personenkraftwagen -bringt es mit sich, daß die Anzeigevorrichtungen keine genaue Aussage über den Inhalt des Kraftstoffbehälters machen können, weil schon kleine Änderungen der Höhe des Kraftstoffspiegels Unterschiede von mehreren Litern bedeuten können.Integrated 'additional tank for the fuel tank for motor vehicles normally very flat design of fuel tanks in motor vehicles - In particular of passenger cars - it entails that the display devices cannot make an exact statement about the contents of the fuel tank because even small changes in the height of the fuel level differences of several Can mean liters.

Diese Eigenschaft führt dazu, daß man die nächste Tankstelle ansteuert, um beim Tanken festzustellen, daß die Restmenge noch ca. 40 km weiter gereicht hätte.This property leads to the fact that one drives to the next gas station, to find out when refueling that the remaining amount would have lasted about 40 km further.

Dadurch ist der Effektivinhalt eines Tanks jeweils 8 - 10 Liter kleiner als in den Werksangaben genannt.This means that the effective volume of a tank is 8-10 liters less than mentioned in the factory specifications.

Andererseits kann der Versuch, die Restmenge besser auszunutzen, dazu führen, den Restinhalt zu überschätzen, was zum Liegenbleiben - mit allen Folgeerscheinungen - führen kann, besonders dann, wenn die Anzeige der Tankuhr veränderlich ist, was der Regelfall zu sein scheint.On the other hand, the attempt to make better use of the remaining amount can do so lead to overestimating the remaining content, which leads to stalling - with all the consequences - Can lead, especially if the display of the fuel gauge is variable, what the rule seems to be.

Die Erfindung beinhaltet einen integrierten Zusatztank mit einem bekannten Fassungsvermögen, der sich kurz vor Leerung des Haupttanks selbsttätig entleert. Der Beginn der Leerung wird dem Fahrer angezeigt (Xontrollampe), womit - je nach Verbrauch des Motors - die noch erreichbare Kilometerzahl bekannt ist. Je nach Motortyp wird diese Entfernung zwischen 30 km und 60 km liegen und ist für jeden Fahrzeugtyp fast konstant.The invention includes an integrated auxiliary tank with a known one Capacity that is automatically emptied shortly before the main tank is emptied. The start of emptying is indicated to the driver (X control lamp), which - depending on the Engine consumption - the number of kilometers that can still be achieved is known. Depending on the engine type this distance will be between 30 km and 60 km and is for each vehicle type almost constant.

Die Erfindung ist dadurch gekennzeichnet, daß sich in dem Kraftstofftank Bild 1 - bestehend aus der oberen Schale Figur t und der unteren Schale Figur O - ein integrierter Zusatztank Figur (a) befindet, der an der oberen Schale Figur Q befestigt ist. Der Zusatztank Figur O4 ragt in eine in der unteren Schale eingepreßte Tasse, Figur O die verhindern soll, daß bei Schrägstellung des Fahrzeuges oder bei Schwankungen des Kraftstoffspiegels der Zusatztank Figur z durch Lufteintritt vorzeitig entleert wird.The invention is characterized in that in the fuel tank Image 1 - consisting of the upper shell figure t and the lower shell figure O - an integrated Additional tank figure (a) is located at the top Shell figure Q is attached. The additional tank figure O4 protrudes into one in the lower one Cup pressed-in cup, figure O, which is intended to prevent the Vehicle or in the event of fluctuations in the fuel level, the additional tank figure z through Air inlet is emptied prematurely.

Bild 2 zeigt den Tankboden mit Tasse Figur 03 und die von der Tasse abgehende Benzinleitung Figur O , wodurch eine ununterbrochene Treibstoffzuführung gewährleistet wird. In Bild 2 ist auch eine mögliche Schrägstellung des Kraftstoffspiegels eingezeichnet.Figure 2 shows the tank bottom with the cup Figure 03 and that of the cup outgoing fuel line Figure O, creating an uninterrupted fuel supply is guaranteed. Figure 2 also shows a possible inclination of the fuel level drawn.

Wird nun während der Fahrt der Treibstoffspiegel bis unter den unteren Rand des Zusatztanks Figur z abgesenkt, kann Luft in denselben eintreten, wodurch eine sukzessive Leerung des Zusatztanks Figur z beginnt. Bild 3 zeigt den Vorgang der Leerung.The fuel level will now fall below the lower level while driving Lowered edge of the additional tank figure z, air can enter the same, whereby a successive emptying of the additional tank figure z begins. Figure 3 shows the process of emptying.

Schon im ersten Augenblick dieses Leerungsvorganges wird derselbe durch den Kontaktgeber Figur z dem Fahrer gemeldet. Der Fahrer ist nun genau informiert, welche Wegstrecke mit dem Kraftstoffrest zurückgelegt werden kann.Already in the first moment of this emptying process it becomes the same reported to the driver by the contactor figure z. The driver is now precisely informed what distance can be covered with the remaining fuel.

Dabei wäre es von Vorteil, den Inhalt des Zusatztanks Figur z so zu bemessen, daß durchweg noch eine Kilometerreserve von 50 km gewährleistet ist.It would be advantageous to show the contents of the additional tank in this way dimensioned so that a kilometer reserve of 50 km is guaranteed throughout.

Beim Füllen des Tanks mit Kraftstoff geht die Füllung beider Tanks gleichmäßig vor sich, da durch das Ventil Figur z zwar Luft aus- aber nicht einströmen kann. Dadurch wird garantiert, daß eine Entleerung des Zusatztanks Figur 04 erst dann erfolgt, wenn der Haupttank Figur 0 und t fast entleert ist, und daß die Füllung ohne jegliche Maßnaiyme zusätzlicher Art wie üblich vorgenommen werden kann.When filling the tank with fuel, the filling of both tanks goes evenly in front of you, since air flows out but not in through valve Figure z can. This guarantees that the additional tank (FIG. 04) will only be emptied then occurs when the main tank figure 0 and t is almost empty, and that the filling can be carried out as usual without any additional measures.

Die aus dem Zusatztank Figur Q4durch das Ventil 6 entweichende Luft strömt über Leitung Figur 7 in den Haupttank Figur 0 und 2 zurück, der auf herkömmliche Art entlüftet wird.The air escaping from the additional tank Figure Q4 through valve 6 flows back via line Figure 7 into the main tank Figure 0 and 2, which is based on conventional Art is vented.

PATENTANSPRUCH Die Erfindung umfaßt alle auf dem Vakuum-Prinzip beruhenden Ausführungen von integrierten Zusatztanks, deren Entleerung erst beginnen kann, wenn der fallende Kraftstoffspiegel eine Luftzufuhr in den Zusatztank ermöglicht, wodurch eine echte Funktion als Reservetank gewährleistet ist. PATENT CLAIM The invention includes all based on the vacuum principle Versions of integrated additional tanks, the emptying of which can only begin, if the falling fuel level allows air to be supplied to the additional tank, whereby a real function as a reserve tank is guaranteed. Dabei ist die Ausbildung der Tasse, die Form des integrierten Zusatztanks, die Art des Ventils und die Anordnung der Er.tlüftungsleitung von sekundärer 3edeutung, das heißt, alle notwendigen Aggregate sind bekannte Maschinenelemente und dienen lediglich zur Einhaltung der planmäßigen Funktion und' können demnach unterschiedlicher Ausbildung seinThe design of the cup, the shape of the integrated additional tank, the type of valve and the arrangement of the ventilation duct are of secondary importance, that is, all the necessary units are known machine elements and are used only to maintain the planned function and 'can therefore be different Be training
