Description

Procédé et dispositif de traitement de fluideFluid treatment method and device
La présente invention concerne un procédé et dispositif pour traiter un carburant, en particulier un carburant destiné à alimenter un moteur à combustion interne.The present invention relates to a method and device for treating a fuel, in particular a fuel intended to supply an internal combustion engine.
On connaît un nombre considérable de dispositifs magnétiques destinés à traiter des fluides, le plus souvent l'eau pour empêcher la formation de tartre. On connaît cependant aussi le traitement magnétique du carburant pour moteur afin de réduire les composés les plus nocifs rejetés par ce moteur et/ou améliorer les performances de ce moteur.A considerable number of magnetic devices are known which are intended to treat fluids, most often water to prevent the formation of scale. However, the magnetic treatment of engine fuel is also known in order to reduce the most harmful compounds released by this engine and / or improve the performance of this engine.
On citera notamment les demandes de brevet européen publiées sous les n° 0 073 077, 0 235 070, 0 544 395, 0 473 133 et la demande PCT WO 93/10894.Mention will in particular be made of the European patent applications published under the numbers 0 073 077, 0 235 070, 0 544 395, 0 473 133 and the PCT application WO 93/10894.
Le plus souvent le carburant est amené à circuler dans un conduit entouré d'aimants permanents ou plus rarement entourant un aimant permanent . De très nombreuses configurations d'aimants permanents ont été décrites et revendiquées .Most often the fuel is caused to circulate in a conduit surrounded by permanent magnets or more rarely surrounding a permanent magnet. Many configurations of permanent magnets have been described and claimed.
La présente invention a pour but de proposer une amélioration à ce type de procédé et à un dispositif adapté pour appliquer cette amélioration. Le dispositif est facile à adapter par exemple à des véhicules à moteur, à des brûleurs ou à des groupes électrogènes, et permet d' atteindre des performances améliorées, essentiellement au niveau de la consommation et des émissions de fumées (opacité) pour un moteur Diesel.The object of the present invention is to propose an improvement to this type of process and to a device suitable for applying this improvement. The device is easy to adapt for example to motor vehicles, burners or generator sets, and allows achieve improved performance, mainly in terms of consumption and smoke emissions (opacity) for a diesel engine.
L'invention propose un dispositif de traitement d'un carburant caractérisé en ce que le carburant destiné à alimenter un moteur est aspiré à partir d'un espace confiné soumis à un champ magnétique, ledit espace , formant éventuellement un sous-réservoir, faisant partie d'un volume principal formant réservoir ou étant en communication avec ce réservoir principal.The invention provides a device for treating a fuel, characterized in that the fuel intended to supply an engine is sucked in from a confined space subjected to a magnetic field, said space, possibly forming a sub-tank, forming part of a main volume forming a reservoir or being in communication with this main reservoir.
Dans la présente description, les termes "confiné" et "espace confiné ou de confinement " se rapportent à un volume essentiellement plus refermé que ne l'est celui à partir duquel le carburant d'un réservoir usuel est aspiré, ce volume devant cependant être ouvert ou en communication directe avec le volume plus important constituant l'essentiel du réservoir. L'effet de confinement aux environs de la sortie de carburant limite l'effet de mélange global du carburant à ce niveau, effet de mélange dû à l'agitation normale du réservoir.In the present description, the terms "confined" and "confined space or confinement" refer to a volume which is essentially more closed than is that from which the fuel from a conventional tank is sucked up, this volume however having to be open or in direct communication with the larger volume making up the bulk of the tank. The effect of confinement in the vicinity of the fuel outlet limits the overall mixing effect of the fuel to this level, mixing effect due to the normal agitation of the tank.
Le rapport du volume de l'espace confiné et du volume du réservoir principal est de préférence inférieur à 1:10, plus préférentiellement inférieur à 1:50. Le volume de l'enceinte est néamnoins plus spécifiquement dépendant de la consommation du moteur de sorte que le temps de résidence moyen dans l'enceinte comprenant l'élément actif magnétique variera de préférence de 5 à 20 min. de préférence environ 10 min. Selon un mode de réalisation, l'espace confiné peut être une enceinte immergée dans le réservoir ou située en dehors du réservoir. Il peut cependant aussi s'agir d'un endroit particulier du réservoir, le confinement étant provoqué par exemple par un évidement de forme variée le long d'une paroi, généralement le fond du réservoir. Selon un cas particulier, une simple plaque peut créer un effet de compartiment apte à produire l'effet selon l'invention. La forme générale du réservoir peut également présenter une partie de confinement. Un volume défini, totalement ou partiellement par une paroi ajourée ou simplement trouée située à l'intérieur du réservoir, constitue également un espace de confinement selon l'invention.The ratio of the volume of the confined space to the volume of the main tank is preferably less than 1:10, more preferably less than 1:50. The volume of the enclosure is nevertheless more specifically dependent on the consumption of the engine so that the average residence time in the enclosure comprising the magnetic active element will preferably vary from 5 to 20 min. preferably about 10 min. According to one embodiment, the confined space can be an enclosure immersed in the tank or located outside the tank. However, it can also be a particular place in the tank, the confinement being caused for example by a recess of various shape along a wall, generally the bottom of the tank. In a particular case, a simple plate can create a compartment effect capable of producing the effect according to the invention. The general shape of the tank can also have a confinement part. A defined volume, totally or partially by a perforated or simply perforated wall located inside the tank, also constitutes a confinement space according to the invention.
L'espace confiné peut également avantageusement provenir du système de jauge du réservoir le plus souvent offrant en effet un confinement partiel le long d'une paroi, par exemple sous la forme d'un cylindre ouvert ou d'une plaque hémicylindrique .The confined space can also advantageously come from the tank gauge system most often offering in fact partial confinement along a wall, for example in the form of an open cylinder or of a semi-cylindrical plate.
Selon une forme particulière de l'invention, le système de jauge, et le dispositif selon l'invention sont combinés. Les systèmes de jauge en effet comprennent souvent déjà un espace de confinement selon l'invention, par exemple sous la forme d'une plaque hémicylindrique fixée à la paroi et protégeant un capteur de jauge.According to a particular form of the invention, the gauge system, and the device according to the invention are combined. In fact, the gauge systems often already include a confinement space according to the invention, for example in the form of a semi-cylindrical plate fixed to the wall and protecting a gauge sensor.
Selon un premier mode de réalisation de l'invention, on propose un dispositif destiné à être immergé, au moins partiellement, dans un réservoir de carburant et relié d'une part à la conduite d'admission du carburant vers le moteur et d'autre part à la conduite de retour du carburant de la pompe à carburant, le dispositif comprenant une enceinte munie d'un moyen magnétique 'en communication avec le réservoir de carburant, directement ou via un filtre. Ce filtre sera de préférence un filtre non métallique à microperforations (analogue à ceux utilisé pour les filtres à mazout) .According to a first embodiment of the invention, there is provided a device intended to be immersed, at least partially, in a fuel tank and connected on the one hand to the fuel intake pipe to the engine and on the other hand part to the fuel return line of the fuel pump, the device comprising an enclosure provided with a magnetic means in communication with the fuel tank, directly or via a filter. This filter will preferably be a non-metallic microperforation filter (analogous to those used for oil filters).
On sait que, dans la plupart des véhicules, seulement une partie mineure (p.e. 2 à 10 %) du carburant aspiré par la pompe dans le conduit d'alimentation estutilisée par le moteur, la majeure partie est renvoyée vers le réservoir par une conduite de retour. Le carburant aspiré est ainsi majoritairement recyclé.We know that, in most vehicles, only a minor part (eg 2 to 10%) of the fuel sucked by the pump into the supply line is used by the engine, the major part is returned to the tank by a return. The sucked fuel is thus mainly recycled.
Selon l'invention, un dispositif à aimants est constitué d'une chambre ou un volume en communication ou au moins partiellement ouvert vers le carburant du réservoir et dans lequel la conduite d'aspiration est présente et dans lequel éventuellement , selon un mode de réalisation actuellement préféré, le retour ou le refoulement du carburant débouche .According to the invention, a magnet device consists of a chamber or a volume in communication or at least partially open to the fuel from the tank and in which the suction line is present and in which optionally, according to one embodiment currently preferred, the return or delivery of fuel leads.
Selon un aspect de l'invention, le carburant destiné à la conduite d'alimentation passe dans un, et éventuellement préalablement autour d'une enceinte cylindrique munie d'aimants permanents. Etant donné la proximité immédiate du retour de carburant, il en résulte que le coefficient de recyclage d'une quantité déterminée de carburant est beaucoup plus important qu'en l'absence d'enceinte, la communication vers le réservoir n'étant prévue que pour compenser la partie du carburant véritablement consommée par le moteur. Selon un autre aspect de l'invention, pour un dispositif magnétique présent dans le réservoir à proximité ou relié à la conduite d'admission du carburant vers le moteur, la conduite de retour du carburant débouche à proximité dudit dispositif magnétique relativement aux dimensions du réservoir, par exemple pour un véhicule à réservoir classique à une distance inférieure à 20 cm, de préférence inférieure à 10 cm.According to one aspect of the invention, the fuel intended for the supply line passes through a, and possibly beforehand around a cylindrical enclosure provided with permanent magnets. Given the immediate proximity of the fuel return, it follows that the recycling coefficient of a determined quantity of fuel is much greater than in the absence of an enclosure, the communication to the tank being provided only for compensate for the part of the fuel actually consumed by the engine. According to another aspect of the invention, for a magnetic device present in the tank close to or connected to the fuel intake pipe to the engine, the fuel return pipe opens near said magnetic device relative to the dimensions of the tank , for example for a conventional tank vehicle at a distance of less than 20 cm, preferably less than 10 cm.
Comme il est connu, les aimants permanents p.e. en ferrite ou en néodynium, peuvent être remplacés par des électroaimants en adoptant un montage approprié. La configuration exacte des aimants ne constitue cependant pas une limitation de l'invention.As is known, permanent magnets, eg ferrite or neodynium, can be replaced by electromagnets by adopting an appropriate assembly. The exact configuration of the magnets does not however constitute a limitation of the invention.
En effet, un grand nombre de dispositifs de l'art antérieur de traitement "en ligne" d'un liquide, en particulier d'un carburant, peut être appliqué dans le cadre de la présente invention.Indeed, a large number of devices of the prior art for "on-line" treatment of a liquid, in particular a fuel, can be applied within the framework of the present invention.
Un des avantages de la présente invention, pour une application déterminée p.e. dans un véhicule à moteur, est que les bénéfices de la magnétisation du carburant se font sentir plus vite lors du démarrage du véhicule. On a en effet créé un volume de carburant "activé" disponible dès le démarrage. Sans être tenu par une explication scientifique, on notera que le temps de résidence dans les champs et les mouvements relatifs du ou des champs magnétiques et du carburant sont plus importants que dans un système de l'art antérieur. L'efficacité du système selon l'invention constatée par mesure du CO et opacimetrie est donc plus importante en circulation urbaines et des circonstances où il y a de nombreux démarrage à froid.One of the advantages of the present invention, for a specific application eg in a motor vehicle, is that the benefits of the magnetization of the fuel are felt more quickly when the vehicle is started. We created a volume of "activated" fuel available from the start. Without being bound by a scientific explanation, it will be noted that the residence time in the fields and the relative movements of the magnetic field or fields and of the fuel are greater than in a system of the prior art. The efficiency of the system according to the invention observed by measuring CO and opacimetry is therefore greater in urban traffic and in circumstances where there are numerous cold starts.
Avantageusement, le dispositif magnétique peut être placé dans un réservoir annexe offrant un volume "tampon" inséré dans le circuit d'alimentation du carburant et plus proche du bloc-moteur. Son efficacité sera améliorée surtout au moment de la mise en service. Ceci peut permettre une préparation du carburant de ce réservoir annexe et une meilleure gestion dès la mise en route du moteur.Advantageously, the magnetic device can be placed in an auxiliary tank offering a "buffer" volume inserted in the fuel supply circuit and closer to the engine block. Its efficiency will be improved especially at the time of commissioning. This can allow the preparation of the fuel for this auxiliary tank and better management as soon as the engine is started.
Avantageusement , le système de retour du carburant peut ne recycler qu'une partie du carburant, cette partie pouvant varier automatiquement en fonction de paramètres (débit, température, opacité, consommation, couple sollicité etc..) rassemblés de manière individuelle, par régulation, ou rassemblés par un microordinateur de commande.Advantageously, the fuel return system can recycle only part of the fuel, this part being able to vary automatically as a function of parameters (flow rate, temperature, opacity, consumption, torque requested, etc.) gathered individually, by regulation, or collected by a control microcomputer.
Le procédé et le dispositif selon l'invention permettent donc d'améliorer très sensiblement la performance des moteurs tout en diminuant la pollution. Pour un moteur Diesel provoquant une opacité inférieure à IK m-1 on a observé des baisses d'opacité de 30 à 60 % et des baisses de consommation de 2 à 7 % . Si l'opacité est supérieure à 1 K m-1 la baisse de l'opacité peut varier de 40 à 90 % et la consommation peut baisser de 3 à 25 %.The method and the device according to the invention therefore make it possible to very significantly improve the performance of the engines while reducing pollution. For a diesel engine causing an opacity less than IK m-1, drops in opacity of 30 to 60% and drops in consumption of 2 to 7% were observed. If the opacity is greater than 1 K m-1, the drop in opacity can vary from 40 to 90% and consumption can drop from 3 to 25%.
