Description

FUEL OPTIMIZATION DEVICE

Field of the invention

The present invention relates to a device for optimizing the combustion of a gaseous or liquid hydrocarbon by magnetization, in machines using the combustion of fuel to supply energy, and in particular vehicle engines and boilers. More particularly, it is a device comprising an external magnetic shielding protecting the electrical or electronic elements located in the environment of said device from its magnetic effects.

Brief description of the prior art

In the prior art, many devices exploit the effects of magnetic fields on fluids, intended to facilitate the combustion of mixtures of fluid or gaseous hydrocarbons with combustion air.

A hydrocarbon is an organic compound made up exclusively of carbon and hydrogen atoms, the combustion of which produces energy. Combustion is a chemical reaction associating the hydrocarbon and an oxidizer, generally dioxygen.

When there is not enough oxygen, combustion is incomplete and there is rejection of polluting particles (carbon monoxide, unburned hydrocarbon, nitrogen oxide molecules).

The use of magnetic fields makes it possible to improve the combustion of the hydrocarbon, and therefore the energy efficiency, while reducing the toxic particles emitted.

Hydrocarbons are in fact structured in a “cage” and tend, by default, to be in a stable state and to bond together to form large groups of bundles. The combustion of carbon atoms located at the center of molecules during the combustion process is hampered by the hydrogen atoms surrounding it. In addition, the access of oxygen inside these groups of molecules is made difficult.

Magnetization makes it possible to modify the rotation properties of the outer layer of the hydrocarbon molecule and to increase the reactivity of the fuel. A sufficiently strong ionization field substantially transforms the hydrocarbon atom, making it more volatile and allowing it to attract more oxygen. Thus, an improvement in oxidation increases the efficiency of combustion.

However, the existing magnetic treatment systems for hydrocarbons have a major drawback: integrated in the engines, their magnetic field disturbs the electrical and electronic elements located in their environment and causes malfunctions. Different solutions have been proposed to solve this problem. Patent FR2709331 thus describes a fuel activation device using a magnetic body disposed outside a fuel activation pipe, wrapped in a magnetic induction layer. A magnetic protective layer made of a non-magnetic material is present on the outside of said magnetic induction layer.

The patent FR2919900 proposes a device for treating a fuel using a magnetic field comprising a supply duct and at least two magnets positioned in opposition and held in position by a constraint means. This device comprises at least one element making it possible to confine the magnetic flux generated by the magnets towards the interior of the device, this element covering at least partially a magnet or a group of magnets and being made of a material which is conductive of the non magnetic field magnetizable, preferably pure iron or mu-metal.

Patent CN203685420 relates to an oil reduction device with reduction in emissions capable of catalyzing fuel oil. It comprises an envelope, a plurality of powerful magnetic groups and a plurality of honeycomb catalytic modules. Each magnetic group comprises a magnetic path shielding tube and two non-magnetic separating pieces, each magnetic path shielding tube being cylindrical and made of pure iron.

If all of these devices incorporate magnetic shielding, none is completely effective because said shields do not include the entire device.

In general, the existing devices do not respond to the problem of optimal treatment of a hydrocarbon by magnetization, while completely isolating the environment from magnetic effects.

According to a preferred embodiment, the magnetic shielding means consists of a layer of a material which is conductive of the magnetic field and which cannot be magnetized.

According to a variant, the conductive material of the magnetic field and not magnetizable is mu-metal. Preferably, the magnetic shielding means is multilayer.

Advantageously, the multilayer magnetic shielding means consists of at least two layers of a material which is conductive of the magnetic field and which cannot be magnetized, said layers being separated by at least one layer of aluminum.

Detailed description of preferred embodiments

The device (1) according to the invention is intended to be installed on the arrival of the injection system of a heat engine or of boiler burner pumps, so that a hydrocarbon supplying said engine or said pump systematically circulates inside the device (1) and systematically undergoes a magnetic treatment making it possible to reduce toxic particles while improving energy efficiency.

According to a preferred embodiment, the device (1) according to the invention consists of a housing (2) in which are arranged magnetic modules (3) positioned in a magnetic shielding means (4). The housing (2) of the device (1) is an external envelope serving to contain and maintain the magnetic modules (3) and the shielding (4).

The device (1) has an inlet (En) and an outlet (So) allowing the passage of the hydrocarbon. For the purposes of the description, it is agreed that the longitudinal axis of the device (1) and of its constituent elements is an axis parallel to the axis connecting the inlet (En) to the outlet (So) of the device.

According to a preferred embodiment, the housing (2) has a tubular shape and consists of a central duct (5) comprising at each of its ends a plug (6). The central duct (5), inside which the hydrocarbon circulates, is of circular section and has an outer face and an inner face. On each of its ends, the central duct (5) is tapped.

The plugs (6) positioned at the two ends of the central duct (5) comprise a circular part whose diameter corresponding to the diameter of the section of the central duct (5). The circular piece of plugs (6) is threaded. This thread is complementary to the tapping present at the end of the central duct, and allows fixing by screwing of the plug (6) on the central duct (5).

The circular part (6a) of the plug has in its center an orifice for the passage of the hydrocarbon. The orifice is extended by a grooved sleeve (6b) allowing connection to the pipe of the engine on which it is installed.

Preferably, the central duct (5) and the plugs (6) constituting the housing (2) are made of stainless steel or aluminum.

The hydrocarbon will thus enter the device (1) through the orifice of a first plug (6), circulate along the longitudinal axis of the conduit (5) and exit through the second plug (6) after having been magnetically treated . The direction of passage of the hydrocarbon in the device (1) is represented in FIG. 1 by an entry arrow (En) and an exit arrow (So).

The magnetic modules (3), placed in the housing (2), consist of several neodymium magnets (7) positioned parallel to each other in the length of the module and of a holding structure (8) making it possible to maintain said magnets (7).

The magnets (7) used in the present device (1) are permanent magnets of very high power commonly called neodymium magnets. They are made of an alloy of neodymium, iron and boron (NdFeB).

The neodymium magnets (7) have a parallelepiped shape. In order to increase their contact surface with the hydrocarbon, the neodymium magnets (7) are arranged parallel, with respect to each other, at the center of the module (3), in the axis of the length of the device. The magnets (7) are separated by a space and the hydrocarbon thus flows freely between the magnets. During the magnetic treatment, the neodymium magnets (7) are therefore directly in contact with the hydrocarbon. In order to combat the corrosive effect of the latter, the neodymium magnets (7) are covered with a thin layer of nickel-copper-nickel.

According to a preferred embodiment, the magnets (7) neodymium are five in number and have identical lengths and widths. Their heights differ according to their position in the magnetic module (3), so as to adapt to the circular shape of the latter: the central neodymium magnet is higher than the two magnets which frame it, which are more higher than the two most eccentric magnets.

According to other embodiments, the number and dimensions of the neodymium magnets (7) can vary depending on the size and shape of the device (1) and therefore of the modules (3). According to an alternative embodiment, the magnets can have identical length, width and height.

To optimize their magnetic power, the neodymium magnets are placed in the module (3) so as to create, between them, a magnetic attraction force. Each face of a neodymium magnet (7) is magnetically polarized and faces the face of another neodymium magnet (7) whose polarity is opposite to it. Thus, the north pole of a first neodymium magnet (7) is positioned opposite with the south pole of a second neodymium (7) and the south pole of the first neodymium is positioned opposite with the north pole a third neodymium magnet (7). The most eccentric neodymium magnets in the module have only one of their faces opposite with another neodymium magnet (7).

The holding structure (8) keeps the neodymium magnets (7) in the desired position, parallel to each other. It is made of polyethylene treated against hydrocarbons.

The holding structure (8) has the shape of a hollow cylinder. The magnetic module (3) being inserted inside the housing (2), the diameter of the structure is therefore less than that of said housing

(2). The module holding structure has an internal face and an external face.

On its internal face, the holding structure includes notches (8a) produced in symmetrical and diametrically opposite pairs into which the neodymium magnets (7) will be inserted: each length of each magnet will slide in a notch (8a), two notches now the two lengths of the same magnet (7) being diametrically opposite. Thus, the magnets are held in place and can no longer move, despite the magnetic force attracting them to each other. Furthermore, the notches are spaced from each other, so as to maintain a space between the magnets and to allow the passage of the hydrocarbon between the different magnets.

According to a preferred embodiment, the magnetic modules (3) are two in number. However, their number may vary depending on the size of the device (1), the engine in which it is integrated and the quantity of hydrocarbon to be treated. The device (1) can therefore comprise a single module

(3) or more than 2. The modules are aligned in the same longitudinal axis. In order to protect the environment of the device (1) from the magnetic effects of neodymium magnets (7) whose power is very high, the magnetic modules are positioned in a magnetic shielding means (4) which is a tubular conduit. The magnetic shielding means completely covers the outer lace of the holding means (8) of the module (3) and, when there is a plurality of modules, the assembly formed by the alignment of the modules.

The length of the magnetic shielding means adapts to the number of magnetic modules

(3). Its diameter is less than the diameter of the housing (2) and greater than the diameter of the magnetic modules (3), the shielding conduit (4) being in contact on one of its faces with the housing (2) and on the other of its faces with the modules (3).

According to a preferred embodiment, the shielding means (4) consists of a single layer made of a metal made of an alloy of materials which are conductive of the magnetic field and which cannot be magnetized. Preferably, it is made of mu-metal made up of 80% pure iron and 20% nickel.

To obtain perfect anti-magnetic properties, the sheet of mu-metal used to make the tube is folded and welded, before being heated in an oven of 1178 degrees for 4 hours.

The shielding tube (4), which is similar to a Faraday cage, thus prevents interference from the electrical or electronic parts (electronic computers, capacitors, and all 12/24 volt connections to probes or detectors) of the burner pumps. boilers and fuel injection pumps positioned near the device (1). Also, it promotes the concentration of magnetic effects inside the device (1) and thus prevents losses of magnetic flux.

The device also comprises washers (9) or magnetic continuity means placed between each module and at the ends of all the modules.

The washers (9) are discs with a thickness of approximately 1 millimeter, comprising a central hole. Their diameter is identical to the diameter of the magnetic modules (3).

The washers (9) are made of the same material as the magnetic shielding tube

(4): an alloy of conductive materials of the magnetic field and not magnetizable. Preferably, the washers (9) are made of mu-metal consisting of 80% pure iron and 20% nickel.

An intermediate washer (9) is interposed between each module (3) so as to allow continuity of the total power of the magnetism from the input (En) of the device (1) to its output (So).

An end washer (9) is also positioned at each of the ends formed by the set of magnetic modules (3), which makes it possible to obtain total magnetic shielding in the direction of the input (En) and the output (So) of the device, complementary to the shielding provided by the shielding tube (4). An O-ring (10) or sealing means placed at each end completes the sealing of the device (1): on the inlet side (En) of the device and on the outlet side (So) of the device, the seal (10) is placed between the plug (6) and the central duct (5) of the housing (2).

The seal (10) is treated against hydrocarbons. It has a washer shape and a diameter corresponding to the diameter of the section formed by the inner face of the central duct (5) of the housing.

According to an alternative embodiment of the present invention, the device (1) according to the invention comprises a magnetic shield means (4) consisting multilayer _<

- a first tube (4a) made of conductive material of the magnetic field and not magnetizable and preferably made of mu-metal, in which the magnetic modules (3) are positioned, this first tube being covered by:

- a tube of aluminum or acrylonitrile butadiene styrene (4b), the diameter of which is greater than the first mu-metal tube (4a), said tube of aluminum or acrylonitrile butadiene styrene (4b) being covered by:

- a second complementary shielding tube (4c) made of conductive material of the magnetic field and not magnetizable and preferably made of mu-metal, the diameter of which is greater than the diameter of the tube of aluminum or acrylonitrile butadiene styrene (4b).

The three tubes (4a, 4b, 4c) constituting the multilayer shielding means (4) have the same length and are inserted one into the other, in the order described above, the two layers of mu-metal being separated by the layer of aluminum or acrylonitrile butadiene styrene.

The multilayer shielding means (4) covers all of the magnetic modules and is contained in the housing (2). The association of the different layers of the shielding means (4) makes it possible to increase the efficiency of said shielding.

According to a variant, the shielding means (4) of the device can comprise additional layers of mu-metal and / or layers of aluminum or acrylonitrile butadiene styrene.

According to alternative embodiments, the device can have any shape other than a cylinder and in particular the shape of a cube, a parallelepiped, a hexagonal prism, a triangular prism, etc.

The device (1) thus described is placed in the engine or the boiler as close as possible to the combustion chamber so that the hydrocarbon, after its passage through said device, is immediately associated with oxygen. The magnetization undergone by the hydrocarbon interferes with its molecular structure and allows better quality combustion, increasing energy efficiency and reducing emissions of toxic particles.

All the constituent elements of the device (1) withstand high positive temperatures as well as negative temperatures. Numerous variants possibly capable of being combined can here be made without ever departing from the scope of the invention as defined above.

Insubstantial modifications which would obviously result, for those skilled in the art, from the use or manufacture of which the patent is required here without altering the original provisions, would be mere technical equivalents and also fall within the scope of the present invention.
