The magnets are designed to create a symmetrical magnetic field which transforms para-hydrogen molecules in the fuel into ortho-hydrogen molecules. The magnetic field is created by at least two permanent barium ferrite magnets with inverse poles and axial magnetisation; they are cylindrical in shape and have their axes in line with a plane passing through the centre of the fuel pipe. A variant of the design contains electromagnets which emit a magnetic field varying with the volume of fuel passing through the feed pipe.

Description

La présente invention a pour objet un économiseur de combustible, fluide et à base d'hydrocarbure, destiné à être associé à un conduit amenant le combustible vers l'endroit de combustion, en particulier un moteur à combustion interne, et agencé pour créer, à l'intérieur dudit conduit, un champ magnétique qui sera traversé par le combustible circulant dans ce conduit.The subject of the present invention is a fuel, fluid and hydrocarbon-based, intended to be associated with a pipe bringing the fuel to the place of combustion, in particular an internal combustion engine, and arranged to create, inside said conduit, a field magnetic which will be crossed by the fuel circulating in this conduit.

On sait que les molécules d'hydrogène sont de deux types, à savoir ortho- et para-, dont les propriétés physiques, telles que chaleur spécifique, tension de vapeur, diffèrent légèrement. On sait aussi que les molécules d'hydrogène para-sont plus stables et moins réactives que les molécules d'hydrogène ortho-. On sait enfin qu'en soumettant de l'hydrogène liquide à un champ magnétique approprié, on peut convertir des molécules d'hydrogène para- en molécules d'hydrogène ortho-.We know that the hydrogen molecules are two types, namely ortho- and para-, whose physical properties, such as specific heat, vapor pressure, differ slightly. We also know that the para-hydrogen molecules are more stable and less reactive than hydrogen molecules ortho-. We finally know that by submitting hydrogen liquid to an appropriate magnetic field, you can convert hydrogen molecules para- into ortho- hydrogen molecules.

L'invention a pour but de proposer, d'une part, l'application nouvelle d'un champ magnétique à un combustible contenant de l'hydrogène, tel que gasoil, essence, pétrole, gaz naturel ou gaz provenant du raffinage du pétrole, en vue de transformer le para- hydrogène présent dans le combustible en ortho- hydrogène afin d'accroítre le potentiel énergétique dudit combustible et de ce fait soit en réduire la consommation pour un rendement donné, soit en augmenter le rendement pour une consommation donnée et, d'autre part, de proposer un économiseur de combustible, basé sur le principe susdit, qui est de construction simple et peu coûteuse et qui peut être associé, très rapidement et très facilement, au conduit amenant le combustible à l'endroit de combustion et ce, sans l'aide de pièces de fixation, sans l'aide d'outillage et sans modification de l'installation avec laquelle l'économiseur coopère. Outre l'économie de combustible, la transformation du para- hydrogène en ortho-hydrogène par l'économiseur offre également l'avantage, grâce au fait qu'elle augmente la température de combustion, de réduire, d'une part, les dépôts résiduels à l'endroit de la combustion et, d'autre part, les rejets nocifs dans l'atmosphère.The object of the invention is to propose, on the one hand, the new application of a magnetic field to a fuel containing hydrogen, such as diesel, petrol, petroleum, gas natural or gas from petroleum refining, with a view to transform the para-hydrogen present in the fuel into ortho-hydrogen in order to increase the energy potential of said fuel and therefore reduce consumption for a given yield, or increase the yield for a given consumption and, on the other hand, to propose an economizer of fuel, based on the above principle, which is construction simple and inexpensive and can be combined very quickly and very easily, to the conduit bringing the fuel to the place of combustion without the use of fasteners, without using tools and without modifying the installation with which the economizer cooperates. Besides the economy of fuel, the transformation of para-hydrogen into ortho-hydrogen by the economizer also offers the advantage, thanks to the fact that it increases the combustion temperature, reduce, on the one hand, the residual deposits at the place of combustion and, on the other hand, harmful releases to the atmosphere.

Suivant une forme de réalisation de l'objet de l'invention le champ magnétique susdit est sensiblement constant et est créé par au moins deux aimants permanents de même caractéristiques et dont les pôles sont inversés, ces aimants permanents, dont l'aimantation est axiale, étant alignés suivant un axe perpendiculaire à l'axe du boítier et situés de part et d'autre de ce dernier axe, à distances égales de celui-ci.According to one embodiment of the subject of the invention the above magnetic field is substantially constant and is created by at least two permanent magnets with the same characteristics and whose poles are reversed, these permanent magnets, whose magnetization is axial, being aligned along an axis perpendicular to the axis of the housing and located on both sides of this last axis, at equal distances from it.

Suivant un mode de réalisation avantageux de l'invention, les aimants permanents susdits sont cylindriques et leur axe est confondu avec l'axe précité qui est perpendiculaire à l'axe du boítier, le diamètre des bases de ces aimants étant au moins égal au diamètre externe du conduit précité.According to an advantageous embodiment of the invention, the aforementioned permanent magnets are cylindrical and their axis coincides with the aforementioned axis which is perpendicular to the axis of the housing, the diameter of the bases of these magnets being at less equal to the external diameter of the aforementioned conduit.

Suivant une forme de réalisation particulièrement avantageuse de l'objet de l'invention, le boítier annulaire susdit a une section sensiblement rectangulaire et est constitué de deux demi-anneaux fermés dans chacun desquels sont montés les moyens précités créant le champ magnétique et qui sont articulés, à charnière, le long d'une génératrice de la surface externe du boítier, le diamètre interne de ces demi-anneaux étant au moins égal au diamètre externe du conduit et ceux-ci étant pourvus, le long de leur génératrice diamétralement opposée à la charnière susdite, de moyens agencés, d'une part, pour s'enclencher automatiquement les uns dans les autres lorsque les deux demi-anneaux sont amenés l'un contre l'autre et, d'autre part, pour maintenir ces derniers en position rapprochée lorsque lesdits moyens sont enclenchés.According to a particularly embodiment advantageous object of the invention, the annular housing aforesaid has a substantially rectangular section and is constituted of two closed half-rings in each of which are mounted the the aforementioned means creating the magnetic field and which are articulated, hinged, along a generator of the outer surface of the housing, the internal diameter of these half-rings being at less equal to the external diameter of the conduit and these being provided, along their generatrix diametrically opposite the the aforementioned hinge, of means arranged, on the one hand, to engage automatically into each other when both half rings are brought against each other and, on the other hand, to keep them close together when said means are engaged.

D'autres détails et particularités de l'invention ressortiront de la description des dessins annexés au présent mémoire et qui représentent, à titre d'exemple non limitatif, une forme de réalisation particulière de l'économiseur suivant l'invention.Other details and features of the invention will emerge from the description of the drawings annexed to this memory and which represent, by way of nonlimiting example, a particular embodiment of the following economizer the invention.

Dans les différentes figures, les mêmes signes de référence désignent des éléments identiques.In the different figures, the same signs of reference designate identical elements.

L'économiseur 1, suivant l'invention, est destiné à réduire la consommation de combustible contenant de l'hydrogène et se présentant sous forme liquide ou gazeuse et ce, quel que soit le mode de combustion dudit combustible. Il est particulièrement indiqué pour être associé au système d'alimentation d'un moteur à combustion interne alimenté au gasoil, à l'essence ou au gaz (LPG) et sera, pour un moteur diesel, disposé sur le conduit 2 reliant le filtre à gasoil à la pompe à injection et, pour un moteur à essence ou au LPG, placé sur le conduit 2 situé en amont du carburateur ou du système d'injection. Il améliorera la combustion du combustible circulant dans ce conduit par transformation, dans ce dernier, de l'hydrogène que le combustible contient.The economizer 1 according to the invention is intended for reduce the consumption of fuel containing hydrogen and in liquid or gaseous form, whatever or the mode of combustion of said fuel. It is particularly indicated to be associated with the supply system of a internal combustion engine powered by diesel, gasoline or gas (LPG) and will be, for a diesel engine, placed on the line 2 connecting the diesel filter to the injection pump and, for a petrol or LPG engine, placed on the duct 2 located upstream of the carburetor or the injection system. It will improve the combustion of the fuel circulating in this conduit by transformation, in the latter, hydrogen as fuel contains.

Cet économiseur 1 se compose d'un boítier annulaire 3 agencé pour être disposé autour du conduit 2, qui sera réalisé en matériau neutre, afin que le boítier et le conduit soient coaxiaux; des moyens 4, agencés dans ce boítier 3, pour créer un champ magnétique capable de transformer les molécules d'hydrogène para- contenues dans le combustible en molécules d'hydrogène ortho- et qui est sensiblement symétrique par rapport à un plan passant par l'axe 5 du boítier 3; des moyens 6 agencés pour que ledit champ magnétique soit circonscrit à l'intérieur du volume délimité par les faces externes du boítier 3 et des moyens 7 agencés pour maintenir le boítier 3 en place et en position coaxiale sur le conduit 2.This economizer 1 consists of an annular box 3 arranged to be arranged around the duct 2, which will be produced in neutral material, so that the housing and the duct are coaxial; means 4, arranged in this housing 3, to create a magnetic field capable of transforming hydrogen molecules para-contained in the fuel in hydrogen molecules ortho- and which is substantially symmetrical with respect to a plane passing through the axis 5 of the housing 3; means 6 arranged so that said magnetic field is circumscribed inside the volume delimited by the external faces of the housing 3 and means 7 arranged to hold the housing 3 in place and in position coaxial on the duct 2.

Dans la forme de réalisation de l'économiseur illustré aux dessins, le champ magnétique précité est constant et est créé par deux aimants permanents 8 qui ont les mêmes caractéristiques, avec aimantation axiale, et qui ont leurs pôles inversés. Ces aimants 8 sont alignés suivant un axe 9 qui est perpendiculaire à l'axe 5 du boítier et sont situés de part et d'autre de cet axe 5, à distances égales de ce dernier. Ces aimants 8 sont avantageusement cylindriques et leur axe est confondu avec l'axe 9 susdit et leur diamètre est égal ou supérieur au diamètre externe du conduit 2 auquel est associé l'économiseur.In the embodiment of the economizer illustrated in the drawings, the aforementioned magnetic field is constant and is created by two permanent magnets 8 which have the same characteristics, with axial magnetization, and which have their poles reversed. These magnets 8 are aligned along an axis 9 which is perpendicular to axis 5 of the housing and are located on both sides of this axis 5, at equal distances from the latter. These magnets 8 are advantageously cylindrical and their axis coincides with the aforementioned axis 9 and their diameter is equal to or greater than the diameter external of conduit 2 with which the economizer is associated.

Pour éviter que le champ magnétique créé par les aimants 8 perturbe le fonctionnement de l'appareillage électronique assurant la gestion du moteur à combustion pourvu de l'économiseur 1, les moyens 6 susdits, agencés pour circonscrire ce champ magnétique au boítier 3 de l'économiseur, sont constitués par le matériau neutre constituant ce boítier, tel que du polypropylène, et par une armature 10 qui est réalisée en acier tendre et qui renferme chacune un aimant permanent 8. Cette armature 10 est réalisée pour que pratiquement seule soit libre une face 11' de l'aimant permanent 8 qu'elle contient et qui est tournée vers le conduit 2.To prevent the magnetic field created by magnets 8 disrupts the functioning of the electronic equipment managing the combustion engine equipped with the economizer 1, the aforementioned means 6, arranged to circumscribe this magnetic field in the housing 3 of the economizer, are constituted by the neutral material constituting this case, such as polypropylene, and by a frame 10 which is made of steel tender and which each contains a permanent magnet 8. This frame 10 is made so that practically only one is free a face 11 ′ of the permanent magnet 8 which it contains and which is facing the duct 2.

Pour permettre de placer, rapidement et sans aucun outillage, l'économiseur 1 sur un conduit 2 existant, sans sectionner ou démonter ce conduit, le boítier annulaire 3, suivant l'invention et tel qu'illustré aux dessins, a une section sensiblement rectangulaire et est constitué de deux demi-anneaux 11 fermés dans chacun desquels sont montés les moyens 4 créant le champ magnétique susdit et qui sont réunis entre eux et articulés, à charnière en 12, le long d'une génératrice de la surface externe du boítier. Le diamètre interne de ces demi-anneaux 11 est au moins égal au diamètre externe du conduit 2 et ils sont pourvus, le long de leur génératrice diamétralement opposée à la charnière 12 susdite, des moyens 13 agencés, d'une part, pour s'enclencher automatiquement les uns dans les autres lorsque les deux demi-anneaux 11 constituant le boítier sont amenés l'un contre l'autre et, d'autre part, pour maintenir fermement ces demi-anneaux en position rapprochée lorsque lesdits moyens 13 sont enclenchés.To allow placement, quickly and without any tool, economiser 1 on an existing conduit 2, without cut or dismantle this conduit, the annular housing 3, according to the invention and as illustrated in the drawings, has a substantially rectangular section and consists of two half-rings 11 closed in each of which are mounted the means 4 creating the above magnetic field and which are combined between them and articulated, hinged at 12, along a generator of the external surface of the case. The diameter internal of these half-rings 11 is at least equal to the diameter external of conduit 2 and they are provided, along their generator diametrically opposite the aforementioned hinge 12, means 13 arranged, on the one hand, to engage automatically into each other when the two half-rings 11 constituting the housing are brought against each other and, on the other hand, to firmly hold these half-rings in close position when said means 13 are engaged.

On peut concevoir, suivant l'invention et pour que l'économiseur 1 se fixe automatiquement sur le conduit 2 en position coaxiale avec ce dernier, que le diamètre interne des demi-anneaux 11 est égal au diamètre externe du conduit 2 susdit, de sorte que, lorsque ces deux demi-anneaux formant le boítier 3 sont posés sur le conduit 2 et amenés l'un contre l'autre, les axes de ce dernier et du boítier coïncident automatiquement et de sorte que la fixation dudit boítier 3 sur le conduit est automatiquement assurée par le frottement de la face interne du boítier 3 sur la face externe dudit conduit 2. Le poids de l'économiseur est tel que le frottement du polypropylène constituant le boítier sur le conduit est largement suffisant pour immobiliser fermement le boítier sur ce dernier.It is conceivable, according to the invention and so that the economizer 1 is automatically fixed on the duct 2 in coaxial position with the latter, that the internal diameter of the half-rings 11 is equal to the external diameter of the pipe 2 aforesaid, so that when these two half-rings forming the housing 3 are placed on the duct 2 and brought one against the other, the axes of the latter and of the case automatically coincide and so that the fixing of said housing 3 on the duct is automatically ensured by the friction of the face internal of the housing 3 on the external face of said conduit 2. The weight of the economizer is such that the friction of polypropylene constituting the housing on the conduit is more than sufficient to firmly immobilize the housing on the latter.

Cette façon de faire implique l'existence d'une gamme d'économiseurs dans laquelle sera choisi celui dont le diamètre interne du boítier correspond au diamètre externe du conduit sur lequel sera fixé l'économiseur.This approach implies the existence of a range of economizers in which will be chosen the one whose diameter internal of the housing corresponds to the external diameter of the duct on which will be attached the economizer.

Pour éviter la fabrication et le stockage d'une gamme d'économiseurs, il est prévu, suivant l'invention et comme montré aux dessins, de réaliser un économiseur universel qui peut automatiquement se placer sur le conduit 2 en position correcte et se fixer automatiquement sur ce dernier, quel que soit le diamètre externe du conduit, pour autant qu'il soit inférieur au diamètre interne du boítier 3. Pour ce faire, le diamètre interne des demi-anneaux 11 est supérieur au diamètre externe du conduit 2. Les moyens 7 susdits agencés pour immobiliser le boítier sur le conduit 2 et pour maintenir ceux-ci en position coaxiale sont constitués par deux paires de pattes 14, qui sont flexibles, identiques et dont la longueur est inférieure au rayon interne des demi-anneaux 11. Chaque paire de pattes 14 fait partie d'un demi-anneau et les pattes d'une paire s'étendent, à travers l'évidement 15 du demi-anneau 11 correspondant et dans le prolongement l'une de l'autre, parallèlement au plan passant par la face 16 du demi-anneau qui est destinée à venir en contact avec la face correspondante de l'autre demi-anneau pour former le boítier 3 précité. Comme les distances qui séparent les paires de pattes 14 de ces faces 16, sont égales, la coïncidence des axes du conduit 2 et du boítier 3 est automatiquement assurée par les pattes 14, qui se déforment pour épouser la surface externe du conduit 2, lorsque les deux demi-anneaux 11, qui entourent ce dernier, sont amenés l'un contre l'autre, tandis que la fixation du boítier 3 sur le conduit 2 est automatiquement assurée grâce au frottement des pattes 14 sur celui-ci. A la figure 3, ces pattes 14 sont montrées, en traits interrompus, dans leur position passive et, en traits pleins, dans la position où elles enserrent le conduit 2 et réalisent le positionnement et la fixation du boítier 3 sur ce dernier.To avoid manufacturing and stocking a range economizers, it is planned, according to the invention and as shown in the drawings, to realize a universal economizer which can automatically be placed on the duct 2 in position correct and automatically attach to it, whatever either the external diameter of the conduit, provided that it is smaller than the internal diameter of the housing 3. To do this, the internal diameter of the half-rings 11 is greater than the diameter external of conduit 2. The aforementioned means 7 arranged to immobilize the housing on the duct 2 and to maintain them in coaxial position consist of two pairs of legs 14, which are flexible, identical and shorter in length to the internal radius of the half-rings 11. Each pair of legs 14 is part of a half-ring and the legs of a pair extend, through the recess 15 of the corresponding half-ring 11 and in line with each other, parallel to the plane passing through the face 16 of the half-ring which is intended to come in contact with the corresponding face of the other half-ring to form the aforementioned housing 3. Like the distances that separate the pairs of legs 14 of these faces 16 are equal, the coincidence of the axes of the conduit 2 and the housing 3 is automatically provided by the legs 14, which deform to marry the external surface of the duct 2, when the two half-rings 11, which surround the latter, are brought one against the other, while fixing the housing 3 on the conduit 2 is automatically ensured by the friction of the legs 14 on this one. In Figure 3, these tabs 14 are shown, in broken lines, in their passive position and, in lines full, in the position where they enclose the duct 2 and carry out the positioning and fixing of the housing 3 on this latest.

Ces parties 17 et 18 présentent des organes de repérage 19 agencés pour les placer automatiquement en position correcte l'une par rapport à l'autre lorsqu'on les rapproche, l'une de l'autre, suivant la flèche 21 (figure 1) et suivant leur axe, ainsi que des moyens d'assemblage 20 qui permettent de les immobiliser l'une para rapport à l'autre. Ces parties de boítier 17 et 18 présentent des éléments de fixation 20' des aimants 8, qui créent le champ magnétique, et sont avantageusement scellées, lorsqu'elles sont réunies, par un joint de silicone.To simplify the manufacture of the case 3 above and facilitate the fitting and fixing of the aforementioned means 4 creating the magnetic field in this case, it is advantageously produced, according to the invention and as shown in the drawings, in two parts 17 and 18 which are arranged so that, when they are brought together, along axis 5 of the housing 3, they form the two half-rings 11 above. These parts 17 and 18 have locating members 19 arranged to automatically place them in correct position when compared, when compared the other, along arrow 21 (FIG. 1) and along their axis, as well as assembly means 20 which allow them immobilize one for each other.

Des essais ont été effectués sur un moteur diesel de 1900 cc équipant un véhicule "VW PASSAT" mis en circulation en 1990 et accusant environ 150.000 Km. Dès que ce véhicule a été équipé de l'économiseur suivant l'invention, pourvu de deux aimants permanents, tels que décrits ci-dessus et réalisés en barium ferrite (Br 3800 G, HcB 2300 Oe et Bh max 3MG Oe), l'économie de gasoil a été de l'ordre de 12%. D'autres essais effectués sur un autre véhicule équipé d'un moteur a essence usagé de 4200cc de cylindrée, à l'aide du même économiseur que le moteur diesel susdit, ont démontré une chute de la consommation supérieure à 15%.Tests were carried out on a diesel engine of 1900 cc fitted to a "VW PASSAT" vehicle put into circulation 1990 and covering approximately 150,000 Km. As soon as this vehicle was equipped with the economizer according to the invention, provided with two permanent magnets, as described above and made of barium ferrite (Br 3800 G, HcB 2300 Oe and Bh max 3MG Oe), the fuel economy was around 12%. Other tests carried out on another vehicle fitted with a petrol engine used 4200cc displacement, using the same economizer as the aforementioned diesel engine, have shown a drop in consumption greater than 15%.

Il doit être entendu que l'invention n'est nullement limitée à la forme de réalisation décrite et que bien des modifications peuvent être apportées à cette dernière sans sortir du cadre du présent brevet.It should be understood that the invention is in no way limited to the embodiment described and that many modifications can be made to the latter without leaving the of this patent.

C'est ainsi que l'on pourrait concevoir, suivant l'invention, un économiseur 1 dont le champ magnétique serait variable en fonction de la quantité de combustible circulant dans le conduit 2 précité. Ce champ magnétique serait alors créé par au moins deux électro-aimants ayant les mêmes caractéristiques et dont les pôles seraient inversés. Ces électro-aimants, dont l'aimantation est axiale seraient alignés suivant un axe perpendiculaire à l'axe 5 du boítier 3 et situés de part et d'autre de cet axe 5 et à distances égales de celui-ci. Ces deux électro-aimants seraient alimentés, en synchronisme avec les moyens déterminant la quantité de combustible circulant dans le conduit précité, de manière à ce que l'intensité du champ magnétique créé soit plus importante lorsque la quantité de combustible augmente et soit moins importante lorsque cette dernière diminue.This is how one could conceive, according to the invention, an economizer 1 whose magnetic field would be variable depending on the amount of fuel flowing in the conduit 2 above. This magnetic field would then be created by at minus two electromagnets with the same characteristics and whose poles would be reversed. These electromagnets, including the magnetization is axial would be aligned along a perpendicular axis to axis 5 of the housing 3 and located on either side of this axis 5 and at equal distances therefrom. These two electromagnets would be fed, in synchronism with the means determining the amount of fuel flowing in the duct above, so that the intensity of the magnetic field created is greater when the amount of fuel increases and is less important when the latter decreases.
