Abstract
Description
- The invention relates to a device for preventing the introduction of a fuel nozzle for unleaded fuel into the filler neck of a fuel tank of a motor vehicle fitted with a diesel internal combustion engine.
- German Published Patent Application Nos. 36 41 274 and 196 39 825 disclose refueling blocks for the filler necks of fuel tanks, which can be used to prevent the introduction of fuel nozzles for leaded fuel or for diesel fuel in motor vehicles which must be refueled exclusively with lead free fuel.
- Refueling blocks of this type have been well-established for many years and are still being used to reliably prevent damage to internal combustion engines or catalytic converters of such motor vehicles. However, it should be noted that blocks of this type are relatively simple to construct, since the fuel nozzles for unleaded fuel have a smaller diameter than the fuel nozzles for leaded fuel or for diesel fuel, and therefore introduction of the abovementioned fuel nozzles is in principle already prevented.
- It is, however, precisely the other way around in the case of motor vehicles having diesel internal combustion engines, and so unleaded fuel can be supplied without any problem to such vehicles from fuel nozzles having a relatively small diameter. In the case of conventional diesel internal combustion engines which operate in accordance with the precombustion chamber principle this is not a problem which needs to be taken seriously and particularly in winter the addition of up to 30% petrol to the diesel fuel is even recommended so as to prevent the diesel fuel “becoming sludgy” at low temperatures.
- However, what is not a problem in the older precombustion chamber diesel internal combustion engines may lead to considerable damage in the case of the common-rail diesel internal combustion engines which are ever more frequently to be found, since the high-pressure pump of such internal combustion engines requires the diesel fuel in order to lubricate it. If a relatively large amount of petrol, in particular unleaded petrol, is then placed in such diesel internal combustion engines, insufficient lubrication may very rapidly occur in the high-pressure pump, with the result that the latter becomes blocked and further operation of the internal combustion engine is not possible. In actual fact, this has already led to broken-down vehicles along with the trouble associated therewith.
- Therefore, it is an object of the present invention to provide a device which is used in motor vehicles fitted with a diesel internal combustion engine to prevent fuel nozzles for unleaded fuel from being able to be introduced into the filler neck.
- The blocking element according to the present invention is provided to prevent the introduction of a fuel nozzle into the filler neck leading to the fuel tank. Only when the at least one opening element which interacts with the blocking element produces an appropriate signal does the blocking element open and release the access to the filler neck. This result may occur, however, only when a fuel nozzle for diesel fuel is introduced, and the introduction of a fuel nozzle for unleaded fuel, and therefore the refueling of the fuel tank with unleaded fuel, is thereby substantially prevented.
- In accordance with the present invention, it is not possible for unleaded fuel to be filled into a motor vehicle having a diesel internal combustion engine, which ensures reliable functioning of diesel internal combustion engines, particularly those operating in accordance with the common-rail principle. One particular advantage of the present invention is that existing fuel nozzles do not have to be retrofitted, as was the case, for example, when unleaded fuel was introduced.
- One very functionally reliable configuration of the invention which may be realized with little structural outlay may be produced if there are arranged on the inner circumference of the filler neck at least two opening elements which project into the filler neck and are at such a distance from one another that a fuel nozzle which is introduced into the filler neck and is intended for unleaded fuel does not touch at least one of the opening elements, and in that a fuel nozzle which is introduced into the filler neck and is intended for diesel fuel touches all of the opening elements, in which case, when all of the opening elements are simultaneously touched, the opening elements produce a signal for opening the blocking element.
- The at least two opening elements may be configured as contact sensors which produce an electric signal for opening the blocking element. An arrangement of this type which is equally simple and may be converted cost effectively may also be retrofitted in already existing motor vehicles, in which case very reliable functioning would be provided at the same time due the electronically operating contact sensors.
- Alternatively, the at least two opening elements may also be configured as projections which protrude into the filler neck and whose distance from one another would be greater than the outer diameter of a fuel nozzle for unleaded fuel, in which case the projections, when touched by a fuel nozzle for diesel fuel, would release the blocking element. This arrangement may also be usable as retrofitted solution and would ensure functioning even independently of a power supply.
- FIG. 1 is a schematic view of a motor vehicle having an internal combustion engine and a fuel tank connected to the internal combustion engine.
- FIG. 2 illustrates a first example embodiment of a device according to the present invention.
- FIG. 3 illustrates a second example embodiment of a device according to the present invention.
- FIG. 4 is a cross-sectional view of the device illustrated in FIG. 3 taken along the line IV-IV.
- FIG. 1 schematically illustrates a
motor vehicle 1 having a dieselinternal combustion engine 2 which operates in the present case in accordance with the common-rail principle. Afuel tank 4 is connected to the dieselinternal combustion engine 2 via afuel line 3. Thefuel tank 4 is provided in a conventional manner with afiller neck 5 via which thefuel tank 4 may be filled with diesel fuel from afuel pump 7 by afuel nozzle 6. - In order to prevent the introduction of a
fuel nozzle 6′ for unleaded fuel into thefiller neck 5 of thefuel tank 4, adevice 8 is accommodated in thefiller neck 5 of thefuel tank 4, a first example embodiment of which device is illustrated in greater detail in FIG. 2. - The
device 8 illustrated in FIG. 2 includes ablocking element 9 which closes thefiller neck 5 and in its rest position prevents the introduction both of thefuel nozzle 6 for diesel fuel and the introduction offuel nozzles 6′ for unleaded fuel, which, as is conventional, have a smaller outer diameter. There are arranged on the inner circumference of thefiller neck 5, in the present case on the blockingelement 9, three opening elements 10 which project into thefiller neck 5 and are configured in the illustrated example embodiment ascontact sensors 10 a. - The
contact sensors 10 a are at such a distance from one another that afuel nozzle 6′ which is introduced into thefiller neck 5 and is intended for unleaded fuel does not touch at least one of thecontact sensors 10 a. As a result, opening of the blockingelement 9 is not possible, and thefuel nozzle 6 may therefore be introduced into thefiller neck 5 only as far as the blockingelement 9, which prevents thefuel tank 4 from being filled with unleaded fuel. The diameter of thefuel nozzle 6′ for unleaded fuel is illustrated by the inner circle of dashed lines in FIG. 2. - If, however, the
fuel nozzle 6 for diesel fuel is introduced into thefiller neck 5, then its larger diameter, which is indicated by the outer dashed line, results in the fuel nozzle touching all of the opening elements 10 which, when touched simultaneously, produce a signal for opening the blockingelement 9. Due to the configuration of the opening elements 10 ascontact sensors 10 a the signal in this case is an electric signal which may, for example, ensure that theblocking element 9 is folded away into the interior of thefiller neck 5. For this purpose, the blockingelement 9 may be configured as a flap. Alternatively, the blockingelement 9 may also be configured as a slide and may be moved away in the radial direction. - Instead of the three opening elements10 illustrated, just two opening elements 10 may be provided, it being necessary to ensure in each case that the
fuel nozzle 6′ for unleaded fuel cannot simultaneously touch both opening elements 10, but thefuel nozzle 6 for diesel fuel would always touch all of the opening elements 10. If this condition is satisfied, any other number of opening elements 10 may also be possible. This principle also applies to the example embodiment of thedevice 8 described below. - FIGS. 3 and 4 schematically illustrate another example embodiment of the
device 8 with three opening elements 10 being provided on the inner circumference of thefiller neck 5. These opening elements 10 are configured asprojections 10 b which protrude into thefiller neck 5 and whose distance with respect to one another is again larger than the outer diameter of thefuel nozzle 6′ for unleaded fuel, and which are arranged in the present case offset with respect to one another by 120° in each case. Again, the diameter of thefuel nozzle 6′ for unleaded fuel and the diameter of thefuel nozzle 6 for diesel fuel are illustrated as circles of dashed lines having a small and large diameter, respectively. - If the
fuel nozzle 6, as illustrated in FIG. 4, is introduced into thefiller neck 5, then it presses simultaneously onto the threeprojections 10 b which each pivot as a result about anaxis 12 extending perpendicularly to acentral axis 11 of thefiller neck 5. The blockingelement 9 is divided into threesegments 9 b of the same size and onesegment 9 b in each case is assigned to one of theprojections 10 b via an outwardly protrudinglever element 13. Each individual projection lob presses onto the assignedlever element 13 which in this manner ensures that thesegments 9 b pivot about anaxis 14 likewise extending perpendicularly to thecentral axis 11. By this pivoting of thesegments 9 b, thefiller neck 5 is released for thefuel nozzle 6. Theprojections 10 b and thelever elements 13 are held in their closed position byspring elements device 8 returns to its blocking position when thefuel nozzle 6 is removed. - It may be seen that the
fuel nozzle 6′ for unleaded fuel cannot simultaneously touch all threeprojections 10 b and for this reason it is not possible to introduce afuel nozzle 6′ of this type into thefiller neck 5. - In another example embodiment of the present invention, a single opening element10 may be arranged on the inner circumference of the
filler neck 5, which opening element, for example by inducing a magnetic field, detects the diameter of thefuel nozzle 6 and if the diameter is correct releases thefiller neck 5 by removing the blockingelement 9, for example by an electric signal.
