DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to a fuel reformer,
In particular, the present invention relates to a reformer capable of improving the combustion efficiency of a hydrocarbon fuel.

[0002]

2. Description of the Related Art Hydrocarbon fuels such as gasoline, light oil and heavy oil are generally used in vehicles and ships. It is said that such a hydrocarbon-based fuel has a state in which fuel molecules having a particle size of about 50 μm to 100 μm are bonded to each other, and therefore has a small contact area with oxygen and easily causes incomplete combustion. Therefore, it is very important to improve the fuel combustion efficiency in today's environment where resources are depleted.

[0003] On the other hand, it has been practiced to allow fuel to pass through a magnetic field, break bonds of fuel molecules, atomize the fuel, and increase combustion efficiency (Japanese Patent Laid-Open No. 04-323296).

278, JP-A-09-176660, JP-A-10-
No. 47650, etc.). The use of the fuel that has been subjected to the magnetic treatment in this manner can reduce the fuel consumption, reduce the emission of nitrogen oxides (NOX) and carbon monoxide, and, in the case of a diesel engine, reduce the amount of black in the exhaust gas. It has been reported that smoke can be reduced.

[0004]

However, in the conventional fuel reforming system, the fuel is allowed to pass through the magnetic field only instantaneously because the fuel is allowed to pass through the magnetic field. It was the fact that was not obtained.

In the conventional fuel reforming method, a method of setting a magnet body outside a fuel supply pipe and a method of providing a housing containing a magnet body in the middle of the fuel supply pipe are generally adopted. However, in the former method, the lines of magnetic force are disturbed by the fuel supply pipe, so that a magnetic pole having predetermined characteristics cannot be formed in the fuel pipe, and a part of the fuel flows without crossing the magnetic field, which also provides a sufficient reforming effect. There was a problem that can not be.

[0006] On the other hand, although the latter method allows the fuel to pass through the magnetic field without fail, it is very complicated to equip the fuel, and there is a problem that it is impossible for a layman who does not have specialized knowledge about the vehicle structure to equip the fuel. there were.

SUMMARY OF THE INVENTION In view of the above problems, an object of the present invention is to provide a fuel reformer which can be easily installed by amateurs and can surely reform fuel.

[0008]

Means for Solving the Problems The inventor of the present invention has made intensive studies to solve the above-mentioned problems, and found that when a magnet body is put into a fuel tank, the fuel in the fuel tank always comes into contact with the magnet body and the magnet body is in contact with the magnet body. He came up with the idea of being able to easily cross the magnetic field and set it easily even for amateurs without knowledge of vehicle structure. However, if the magnet body is suspended from the fuel supply port of the fuel tank using a chain or the like, for example, the magnet body may collide with the wall surface of the fuel tank due to a running vibration of the vehicle and damage the wall surface. is there.

On the other hand, the present inventor has paid attention to the fact that if the magnet body is magnetically attached to the bottom wall surface in the fuel tank, the possibility of damaging the fuel tank can be eliminated. However, when one surface of the magnet body is magnetically attached to the wall of the fuel tank, the lines of magnetic force are disturbed by the wall of the fuel tank, and the efficiency of magnetic processing is reduced. To obtain the desired processing efficiency, a very large magnetic flux density is required. This necessitates the use of the magnet body, which increases the cost.

Therefore, in the fuel reformer according to the present invention, the same magnetic poles of the first and second magnet bodies are overlapped and fixed to each other by fixing means to form a magnet assembly. A shape in which a surface of one of the first and second magnet bodies facing the superposed surface or a surface of the first and second magnet bodies intersecting the superposed surface matches the bottom wall shape of the fuel tank. The magnet assembly has a size that can be inserted inward from the fuel supply port of the fuel tank or the connection port of the fuel supply pipe to the combustion engine, and is always in contact with the fuel in the tank on the wall surface of the fuel tank. It is characterized in that it is magnetically fixed and fixed in a state in which it is rotated.

One of the features of the present invention is that the magnet assembly is large enough to be inserted into the fuel tank from the fuel supply port of the fuel tank or the connection port of the fuel supply pipe to the combustion engine. In that it is magnetized and held on the bottom wall surface. Thereby, it can be easily set even by an amateur who does not have knowledge of the vehicle structure, and the magnet assembly does not move around due to the running vibration of the vehicle or the like, and there is no possibility of damaging the wall surface of the fuel tank.

Further, since the magnet assembly is fixed to the bottom in the fuel tank, the fuel in the fuel tank always comes into contact with the magnet body and crosses the magnetic field, so that the fuel can be reliably magnetically processed. In particular, when applied to a fuel tank for a vehicle, the fuel always flows due to the running vibration of the vehicle and the like, so that all the fuel in the fuel tank can be magnetically processed. When the fuel is applied to a fuel tank such as a boiler or the like, the fuel in the fuel tank flows by being supplied to the boiler via a fuel supply pipe, so that a similar magnetic processing effect can be expected.

Still another feature of the present invention resides in that the same magnetic poles of the first and second magnet bodies are overlapped and fixed. Thus, for example, when one magnet body is magnetically attached to the wall surface of the fuel tank, the magnet body on the magnetized side is located between the wall surface of the fuel tank where the magnetic pole is magnetized and the magnetic pole on the superposed side. Lines of magnetic force are generated and the desired magnetic field is not formed, but for the other magnet body, lines of magnetic force are generated between the opposite magnetic poles, and the desired magnetic field is formed. When the superposed side of the first and second magnets is magnetically attached to the wall of the fuel tank, the lines of magnetic force in the lower half of the two magnets are disturbed, but the upper half of the magnetic poles of the opposing magnetic poles are disturbed. Magnetic lines of force are generated in between, and the desired magnetic field is formed. As a result, the fuel can be reliably magnetically processed and the combustion efficiency can be increased without using a magnet having a large magnetic flux density.

The magnet assembly should have a sufficiently large area for obtaining the desired reforming effect by the magnetic treatment. On the other hand, in the case of a truck vehicle or the like, the fuel supply port of the fuel tank is sufficiently large, so that the fuel tank can be charged into the fuel tank through the fuel supply port. However, in the case of an ordinary passenger car or the like, the fuel supply port of the fuel tank is small, and the fuel supply port cannot be inserted into the fuel tank. Therefore, a size that can be charged into the fuel tank from the connection port of the fuel supply pipe to the combustion engine is adopted.

Any surface of the magnet assembly may be magnetically attached to the bottom wall surface of the fuel tank. However, depending on the shape of the magnet assembly, there is a risk that the wall surface may fall down due to running vibration of the vehicle and damage the wall surface. Therefore, it is preferable that the surface of the magnet assembly to be magnetically attached to the bottom wall surface of the fuel tank be a surface in which the magnet assembly has the lowest posture in the installed state.

There is no particular limitation as long as one of the first and second magnet bodies has a shape that matches the bottom wall surface of the fuel tank and the two magnet bodies have surfaces that can overlap each other. For example, the superposed surface of the first and second magnet bodies may be a flat surface or a corrugated surface, and the entire magnet assembly may have a semicircular cross-sectional shape or a semi-elliptical cross-sectional shape. Then, it is preferable to use a rectangular parallelepiped rod-shaped magnet as the first and second magnet bodies.

As the fixing means, for example, bands for fixing both ends and the center of the first and second magnet bodies can be adopted. However, when the magnetic flux density of the magnet body is large, the first and second magnet bodies are used. The mutual repulsive force is large, and the fixing work is not only complicated, but also there is a possibility that the fixing operation cannot be performed well. Therefore, it is preferable to employ a housing containing the first and second magnet bodies as the fixing means.

The material of the housing is not particularly limited.
In the case of a material that is magnetically attached to the magnet body, for example, an iron-based metal material, the lines of magnetic force are disturbed, and therefore, it is preferable to avoid adoption. Further, a synthetic resin material can be used, but since it is immersed in the fuel for a long time, there is a concern that the housing may be corroded.

Therefore, the housing is preferably made of a non-ferrous metal material having corrosion resistance to a hydrocarbon fuel, for example, titanium, a titanium alloy, aluminum, an aluminum alloy, copper, or a copper alloy.

[0020]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in detail with reference to specific examples shown in the drawings. 1 to 3 show a preferred embodiment of a fuel reformer according to the present invention. In the figure, a magnet assembly 10 is configured to include a pair of magnet bodies 11a and 11b, and the pair of magnet bodies 11a and 11b has a flat rectangular parallelepiped rod shape, and the upper surface and the lower surface facing each other are different from each other, that is, One surface is magnetized to the N pole and the other surface is magnetized to the S pole.

The south poles of the pair of magnet bodies 11a and 11b are overlapped with each other, and locking metal fittings (fixing means) 12 and 12 having a U-shaped cross section are fitted on both ends thereof. And is stamped and fixed from the outside of the housing 13.

The locking fittings 12, 12 and the housing 1
As the material of No. 3, an aluminum alloy having corrosion resistance to a hydrocarbon fuel is used.

The magnet assembly 10 has a height of 3
cm, width 3 cm, length 11 cm, and can be put into the fuel tank 20 from the fuel supply port 21 of the fuel tank 20 or the connection port 22 of the fuel supply pipe 30 to the combustion engine,
In addition, any of the four wide surfaces of the magnet assembly 10 can be magnetically attached to the flat bottom wall of the fuel tank 20 in the lowest posture.

For example, when reforming the fuel of a vehicle, FIG.
As shown in the figure, the cap 23 of the fuel supply port 21 of the fuel tank 20 of the vehicle is removed, the magnet assembly 10 is put into the fuel tank 20, and the magnet assembly 10 is magnetically attached to the bottom wall surface of the fuel tank 20. .

In this case, when one magnet body 11b of the magnet assembly 10 is magnetically attached to the bottom wall surface of the fuel tank 20, the upper magnet body 11a of the magnet assembly 10 changes from the upper surface N pole to the lower surface S pole. The magnetic lines of force T1 and T2 are generated from the lower north pole to the upper south pole on the lower and upper magnet bodies 11b, but the same magnetic poles are superposed on the two magnet bodies 11a and 11b. Repel each other and are directed to the boundary of the superposition of the two magnet bodies 11a and 11b as shown in FIG.

At this time, in the lower magnet body 11b, the lower N pole is magnetically attached to the fuel tank 20, and the line of magnetic force T2 from the N pole is affected by the wall surface of the fuel tank 20 and exhibits a flat characteristic. The magnetic line of force T1 of the magnet body 11a shows predetermined characteristics.

Also, depending on the manner of introduction, the magnet assembly 1
0 may be magnetically attached to the bottom wall surface of the fuel tank 20 with the overlapping edges of the two magnet bodies 11a and 11b facing downward. In such a case, in the magnet assembly 10, both magnet bodies 11a,
Lines of magnetic force T1 and T2 are generated from the upper half and the lower half of the side N pole of the side surface 11b toward the upper and lower S poles of the superimposed surface, respectively. The magnetic lines of force T1 and T2 in the lower half from the N pole which are magnetically attached to the fuel tank 20 are affected by the wall surface of the fuel tank 20 and exhibit flattened characteristics as shown in FIG. The magnetic lines of force T1 and T2 on the part side show predetermined characteristics.

In this state, when the vehicle travels, the fuel F in the fuel tank 20 travels in the fuel tank 20 as the vehicle travels. Since the fluid flows across a magnetic field having predetermined characteristics formed by the upper halves of the bodies 11a and 11b (FIG. 3)
(See arrow A in FIG. 4 and arrow B in FIG. 4), the fuel is surely reformed.

When the magnet assembly 10 cannot be inserted from the fuel supply port 21 of the fuel tank 20, the fuel supply pipe 30 to the combustion engine, for example, a vehicle engine is removed and the magnet 22 is inserted into the fuel tank 20 from the connection port 22. The assembly 10 can be put in and magnetically attached to the bottom wall of the fuel tank 20.
