Description

La présente invention concerne un dispositif destiné à empêcherThe present invention relates to a device for preventing

l'introduction d'un carburant inadapté dans la tubulure (1) de remplissage du réservoir à carburant d'un véhicule automobile.  the introduction of an unsuitable fuel into the fuel tank filling pipe (1) of a motor vehicle.

On connaît dans l'art antérieur des dispositifs permettant d'empêcher que l'on introduise un carburant inadapté dans le réservoir d'un véhicule, par exemple de l'essence au lieu du gasoil.  Devices are known in the prior art to prevent the introduction of an unsuitable fuel into the tank of a vehicle, for example gasoline instead of diesel.

De tels dispositifs connus comportent des moyens de 10 détrompage, par exemple ceux décrits dans les documents GB 2 287 700 A et GB 2 290 287 A. Ces moyens nécessitent des formes complémentaires du col de remplissage du réservoir et du pistolet de remplissage, ce qui impose des contraintes de conception difficiles à généraliser et ne va pas dans le sens de la standardisation des pièces recherchée de nos jours.  Such known devices include polarizing means, for example those described in GB 2 287 700 A and GB 2 290 287 A. These means require complementary shapes of the filler neck of the reservoir and the filler gun, which imposes design constraints that are difficult to generalize and does not go in the direction of the standardization of the parts sought today.

D'autres dispositifs de détrompage utilisent un clapet mais cela complique considérablement les opérations de remplissage.  Other keying devices use a valve but this greatly complicates the filling operations.

Enfin, d'autres dispositifs connus comportent des moyens d'alerte activés indépendamment du type de carburant introduit, que celui-ci soit adapté ou non. L'alerte est dans ce cas systématique ce qui n'aide pas l'utilisateur à différencier le choix entre un bon carburant et un carburant inadapté. De tels dispositifs connus sont par exemple décrits dans le document GB 2 396 590 A. Aucun de ces dispositifs connus ne permet une alerte exclusivement lorsque le carburant est inapproprié.  Finally, other known devices comprise alert means activated regardless of the type of fuel introduced, whether it is adapted or not. The alert is in this case systematic which does not help the user to differentiate the choice between a good fuel and an unsuitable fuel. Such known devices are for example described in GB 2 396 590 A. None of these known devices allows an alert only when the fuel is inappropriate.

Le but de la présente invention est de pallier les 30 inconvénients précédents.  The object of the present invention is to overcome the above disadvantages.

A cette fin, la présente invention a pour objet un dispositif destiné à empêcher l'introduction d'un carburant inadapté dans la tubulure de remplissage du réservoir à carburant d'un véhicule automobile, caractérisé en ce qu'il comprend des moyens de mesure de la densité du carburant introduit, reliés à un calculateur de comparaison de la valeur de la densité mesurée avec une valeur de densité admise stockée dans une mémoire, ledit calculateur commandant une alerte visuelle et/ou sonore lorsque la densité mesurée ne correspond pas à la valeur de densité admise.  To this end, the present invention relates to a device for preventing the introduction of an unsuitable fuel into the filler neck of the fuel tank of a motor vehicle, characterized in that it comprises means for measuring the the fuel density introduced, connected to a comparison calculator of the measured density value with an admitted density value stored in a memory, said computer controlling a visual and / or audible alert when the measured density does not correspond to the value of accepted density.

Un tel dispositif permet d'alerter l'utilisateur uniquement o lorsque le carburant introduit est inapproprié. De surcroît, il ne nécessite pas des moyens coûteux de mise en oeuvre.  Such a device makes it possible to alert the user only o when the introduced fuel is inappropriate. In addition, it does not require expensive means of implementation.

Ainsi selon des caractéristiques avantageuses de l'invention - des moyens de collecte d'une quantité de carburant sont implantés dans la tubulure de remplissage, de manière à communiquer avec les moyens de mesure de la densité du carburant, lesquels sont implantés sur la surface extérieure de la tubulure de remplissage du réservoir, - les moyens de collecte forment un bec orienté vers le 20 col de remplissage de la tubulure, - les moyens de mesure de la densiité du carburant comprennent un capteur donc le boîtier externe est prolongé par le bec de collecte, traversant la paroi de la tubulure de remplissage du réservoir, L'invention a également pour objet une tubulure de remplissage d'un réservoir à carburant d'un véhicule automobile comprenant un dispositif ayant les caractéristiques précédentes.  Thus according to advantageous features of the invention - means for collecting a quantity of fuel are located in the filler neck, so as to communicate with the fuel density measuring means, which are located on the outer surface of the filler neck of the reservoir, the collection means form a spout oriented towards the filler neck of the pipe, the means for measuring the density of the fuel comprise a sensor, so that the outer casing is extended by the spout of the spout. The invention also relates to a filler neck of a fuel tank of a motor vehicle comprising a device having the above characteristics.

L'invention a également pour objet un procédé de détection du type de carburant introduit dans la tubulure de remplissage du réservoir à carburant d'un véhicule automobile, caractérisé en ce qu'il comprend les étapes consistant à : - mesurer la densité du carburant introduit, comparer la densité du carburant mesurée à une valeur de densité admise stockée dans une mémoire, - commander une alerte visuelle et/ou sonore lorsque la densité mesurée ne correspond pas à la valeur de densité admise.  The invention also relates to a method for detecting the type of fuel introduced into the filler neck of the fuel tank of a motor vehicle, characterized in that it comprises the steps of: - measuring the density of the fuel introduced comparing the density of the measured fuel with an admitted density value stored in a memory; - controlling a visual and / or audible warning when the measured density does not correspond to the admitted density value.

D'autres caractéristiques et avantages de l'invention to apparaîtront plus clairement à la lecture de la description qui va suivre d'un exemple détaillé de réalisation de l'invention et à l'aide des figures annexées dans lesquelles: - la figure 1 est une vue d'une tubulure de remplissage du réservoir à carburant d'un véhicule automobile munie d'un s dispositif de détection du type de carburant introduit selon l'invention, - la figure 2 est une vue rapprochée de l'intérieur de la tubulure de remplissage du carburant, via le col de remplissage, montrant le bec de collecte du carburant selon l'invention.  Other features and advantages of the invention will appear more clearly on reading the following description of a detailed embodiment of the invention and with the aid of the appended figures in which: FIG. a view of a filler neck of the fuel tank of a motor vehicle equipped with a detection device of the type of fuel introduced according to the invention; - FIG. 2 is a close-up view of the inside of the tubing filling the fuel, via the filler neck, showing the fuel collection nozzle according to the invention.

On a représenté à la figure 1 une tubulure 1 de remplissage d'un réservoir à carburant d'un véhicule automobile. Cette tubulure 1 comporte en amont un col 2 de remplissage apte à être fermé par un bouchon 3, et débouche en aval sur le réservoir (non représenté).  FIG. 1 shows a pipe 1 for filling a fuel tank of a motor vehicle. This tubing 1 comprises upstream a filling neck 2 adapted to be closed by a plug 3, and opens downstream on the reservoir (not shown).

Selon l'invention, un dispositif de détection du type de carburant est prévu sur la tubulure 1 de remplissage.  According to the invention, a device for detecting the type of fuel is provided on the filler neck 1.

Ce dispositif comprend des moyens de mesure 4 de la densité du carburant. De tels moyens de mesure 4 comprennent un capteur fonctionnant à partir du principe physique de la poussée d'Archimède. De tels capteurs mesurent la densité du carburant, qui est le rapport entre la masse volumique du carburant en g/cm3 et la masse volumique de l'eau, qui correspond à la valeur de référénce de 1 g/cm3; on peut indifféremment considérer que les valeurs relevées correspondent à la densité du carburant, ou à sa masse volumique exprimées en g/cm3. Ces capteurs sont relativement classiques, simples à mettre en oeuvre et offrent une très bonne précision de mesure, de l'ordre de 0,001g/cm3. En outre, ces capteurs sont légers et très robustes.  This device comprises means 4 for measuring the density of the fuel. Such measuring means 4 comprise a sensor operating from the physical principle of buoyancy. Such sensors measure the density of the fuel, which is the ratio between the density of the fuel in g / cm 3 and the density of the water, which corresponds to the reference value of 1 g / cm 3; it can be considered indifferently that the values recorded correspond to the density of the fuel, or to its density expressed in g / cm3. These sensors are relatively conventional, simple to implement and offer a very good measurement accuracy, of the order of 0.001g / cm3. In addition, these sensors are lightweight and very robust.

Partant du principe que la densité du gasoil est de l'ordre de 0, 845 contre 0,755 pour l'essence (sans plomb 95 ou sans ro plomb 98), et que ces valeurs:sont relativement invariables entre les raffineries puisqu'elles font l'objet d'une réglementation, il est aisé de distinguer le type de carburant introduit dans la tubulure.  Assuming that the density of the gas oil is of the order of 0, 845 against 0.755 for gasoline (unleaded 95 or without ro lead 98), and that these values: are relatively invariable between refineries since they make The object of a regulation is to distinguish the type of fuel introduced into the tubing.

Selon l'invention, des moyens de collecte 5 d'une quantité de carburant sont implantés dans la tubulure 1 de remplissage. Ces moyens 5 sont par exemple constitués d'un bec orienté vers le col de remplissage de la tubulure, de sorte que dès qu'une quantité de carburant est introduite dans la tubulure 1 via le col, une partie de cette quantité de carburant est retenue dans le bec.  According to the invention, means 5 for collecting a quantity of fuel are located in the filling pipe 1. These means 5 consist, for example, of a spout oriented towards the filler neck of the tubing, so that as soon as a quantity of fuel is introduced into the tubing 1 via the neck, part of this quantity of fuel is retained. in the beak.

Selon l'invention, le bec 5 communique avec les moyens de mesure 4 de la densité du carburant implantés sur la surface extérieure de la tubulure 1, plus précisément le bec débouche sur ces moyens de mesure 4. Dans une variante de réalisation de l'invention, les moyens de mesure 4 comprennent un capteur pourvu d'un boîtier externe dont le bec 5 constitue un prolongement. Le bec 5 est introduit dans un orifice ménagé dans la paroi de la tubulure 1 jusqu'à ce que le boîtier du capteur coopère en contact avec la surface extérieure de la tubulure 1.  According to the invention, the spout 5 communicates with the measuring means 4 of the density of the fuel implanted on the outer surface of the pipe 1, more precisely the spout opens on these measuring means 4. In a variant embodiment of the According to the invention, the measuring means 4 comprise a sensor provided with an outer casing whose spout 5 constitutes an extension. The spout 5 is introduced into a hole in the wall of the tubing 1 until the sensor housing cooperates in contact with the outer surface of the tubing 1.

Par ailleurs, les moyens de mesure de la densité du carburant sont reliés à un calculateur (non représenté). Ce calculateur compare la valeur de la densité mesurée avec une valeur de densité admise stockée dans une mémoire. La valeur de la densité admise stockée dans la mémoire du calculateur correspond à la densité du carburant adapté à la motorisation du véhicule. Si le résultat de cette comparaison montre qu'il y a un écart entre la valeur de la densité mesurée et la valeur de la densité admise mémorisée, le calculateur commande alors une alerte visuelle et/ou sonore. Des moyens d'alerte connus sont constitués d'un voyant lumineux et/ou d'un avertisseur sonore tout à fait classiques pour l'homme de l'art. Ces moyens ne seront donc pas développés davantage.  Moreover, the means for measuring the density of the fuel are connected to a computer (not shown). This calculator compares the value of the measured density with an admitted density value stored in a memory. The value of the allowed density stored in the computer memory corresponds to the density of the fuel adapted to the motorization of the vehicle. If the result of this comparison shows that there is a difference between the value of the measured density and the value of the admitted density stored, the computer then controls a visual alert and / or sound. Known warning means consist of a warning light and / or a buzzer quite conventional for those skilled in the art. These means will not be further developed.

La connexion électrique entre les moyens de mesure 4 et o le calculateur est assurée par un fil 6 cheminant le long de la tubulure 1 et fixé à cette dernière pas des moyens de clipsage.  The electrical connection between the measuring means 4 and the computer is provided by a wire 6 running along the pipe 1 and fixed to the latter not clipping means.

Par ailleurs, on notera que si le calculateur entre dans un état de veille au bout d'un certain temps de non utilisation, ce qui est classique pour des raisons d'économie d'énergie, ce calculateur pourra être réveillé lors de l'activation de l'ouverture de la trappe à carburant de manière à être prêt à recevoir une information des moyens de mesure de la densité du carburant.  Furthermore, it should be noted that if the computer enters a standby state after a certain period of non-use, which is conventional for reasons of energy saving, this calculator can be woken up during activation the opening of the fuel hatch so as to be ready to receive information means for measuring the density of the fuel.

Bien entendu, l'invention ne se limite pas au mode de réalisation qui vient d'être décrit et comprend tous les équivalents techniques.  Of course, the invention is not limited to the embodiment that has just been described and includes all the technical equivalents.
