Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention reforms the components of fuel oil by atomizing the molecules of fuel oil such as light oil used in diesel engines by magnetic force to give an incomplete combustion rate of fuel oil. Reduction of nitrogen oxides (NO _x ) and improvement of fuel efficiency, especially regarding improvement of fuel oil reformer, especially by optimizing the arrangement of magnets and the shape of fuel oil flow passage The effect of reforming is improved significantly.

[0002]

2. Description of the Related Art As a conventional fuel oil reforming apparatus using a magnet, for example, one disclosed in Japanese Patent Publication No. 30718/1990 is known. That is, in this conventional fuel oil reforming device, a non-magnetic tube is arranged inside the cylindrical casing to use the non-magnetic tube as a fuel oil passage, and outside the non-magnetic tube in the thickness direction. A large number of ring-shaped permanent magnets having poles are fitted, and more specifically, these ring-shaped permanent magnets are divided into multiple groups, and within each group, the magnets are in close contact with each other in the repulsive direction. Between the groups, the magnets are opposed to each other in an attracting relationship via a spacer.

In such a structure, when a fuel oil such as light oil is passed through a non-magnetic pipe which serves as a fuel oil passage,
The fuel oil comes into contact with the complicated magnetic field created by the above-mentioned many permanent magnets, and the oil molecules of the fuel oil are atomized.As a result, the combustion efficiency is improved, the fuel efficiency is improved, and the generation of nitrogen oxides is reduced. is there.

[0004]

However, since the magnetic fluxes have the property of repelling each other, the magnetic flux density in the inner space of the ring-shaped magnet tends to be lower than the magnetic flux density around the magnet, and therefore the above-mentioned conventional method is used. Like the fuel oil reforming device of No. 1, a structure in which a non-magnetic pipe is arranged in the space formed inside by stacking a large number of ring-shaped magnets and the inside of the non-magnetic pipe serves as a fuel oil passage If so, only a part of the magnetic flux generated by the permanent magnets acts on the reforming of the fuel oil, so that there is a problem that the reforming efficiency of the fuel oil is low. Therefore, in order to obtain a sufficient reforming effect, it is necessary to use a strong and therefore expensive magnet, or to sufficiently lengthen the fuel oil passage so that the fuel oil is in contact with the magnetic field for a long time. In any case, it causes problems such as a significant increase in cost and an increase in size of the device.

As conventional fuel oil reforming devices other than those described in the above publications, for example, various devices described in Japanese Patent Publication No. 59-1760 and Japanese Patent Application Laid-Open No. 63-129161 are known. However, none of the devices has a structure in which the fuel oil reforming efficiency is low because the fuel oil does not pass through only a portion having a high magnetic flux density.

The present invention has been made by paying attention to the unsolved problems of the above-mentioned conventional techniques, and provides a fuel oil reforming device capable of dramatically improving the reforming efficiency. Is intended.

[0007]

In order to achieve the above object, a fuel oil reforming apparatus according to a first aspect of the present invention has a structure in which a pole is formed in a thickness direction inside a casing in which a fuel oil passage is formed. A plurality of plate-shaped permanent magnets having a predetermined distance are arranged such that the flat surfaces face each other and are arranged side by side from the upstream side to the downstream side of the passage, and between the permanent magnets and the inner surface of the casing. Seals leaving some openings,
Further, the openings of the adjacent permanent magnets are shifted in the circumferential direction so that the openings do not overlap with each other.

According to a second aspect of the invention, in the invention according to the first aspect, the adjacent permanent magnets are arranged in an attracting relationship. The invention according to claim 3 is the invention according to claim 1, wherein the adjacent permanent magnets are arranged in a repulsive relationship. Further, in the invention according to claim 4, in the invention according to claim 1, the plurality of permanent magnets are arranged such that the relationship between adjacent permanent magnets alternately repeats the attraction relationship and the repulsion relationship. It is a thing.

The invention according to claim 5 is the invention according to any one of claims 1 to 4, wherein the side plate of the casing surrounding the side surface of the permanent magnet is made of a non-magnetic material. Further, the invention according to claim 6 is the invention according to any one of claims 1 to 5, wherein a plate-shaped member made of a material having a magnetic permeability higher than that of the material of the permanent magnet is brought into contact with the flat surface of the permanent magnet. In such a state, the gap between the plurality of permanent magnets and the opening are not closed.

Furthermore, the invention according to claim 7 is the invention according to any one of claims 1 to 6, wherein the openings of the adjacent permanent magnets are offset from each other by 180 degrees in the circumferential direction. On the other hand, in order to achieve the above object, a fuel oil reforming apparatus according to an invention of claim 8 has a plurality of plate-shaped members made of a magnetic material, which are provided in a casing having an internal passage for fuel oil. The flat surfaces face each other at a distance from each other and are arranged side by side from the upstream side to the downstream side of the passage, and the opening is partially left between the plate member and the inner surface of the casing for sealing. Further, the adjacent plate-shaped members are circumferentially displaced so that the openings do not overlap each other, and the side plate of the casing that surrounds the side surface of the plate-shaped member is made of a non-magnetic material. And the coil of the electromagnet is arranged so as to surround the outer peripheral surface of the side plate.

According to a ninth aspect of the present invention, in the fuel oil reforming apparatus according to the eighth aspect, the openings of the adjacent permanent magnets are offset by 180 degrees in the circumferential direction.

[0012]

According to the first aspect of the invention, since the plate-shaped permanent magnet disposed in the casing and the inner surface of the casing are sealed with a part of the opening left, they are adjacent to each other. A space sandwiched between two matching permanent magnets communicates with each other through the opening. Then, the communication state between the spaces sandwiched by such permanent magnets is continuous from the upstream to the downstream of the fuel oil passage inside the casing, and the openings are not overlapped with the adjacent permanent magnets. Therefore, the fuel oil inside the casing is the space between the two permanent magnets → the opening → the space between the two permanent magnets → the opening → the space between the two permanent magnets → the opening Departments ... will move in that order.

When two plate-shaped permanent magnets having poles in the thickness direction are arranged such that their planes face each other, the two permanent magnets are in an attraction relation (one N pole and the other S pole). In either case (when the poles face each other), in a repulsive relationship (when N poles or S poles face each other), or when a suction relationship and a repulsive relationship are mixed. The magnetic flux density in the space sandwiched by the permanent magnets is the highest.

Therefore, when the fuel oil moves in the casing as described above, the fuel oil passes through the space having the highest magnetic flux density, so that the fuel oil can surely come into contact with many magnetic fluxes. Next, in the invention according to claim 2, since two adjacent permanent magnets are arranged in an attracting relationship with each other, the magnetic flux generated by these permanent magnets is changed from one permanent magnet to the other permanent magnet. It will grow straight toward.

For this reason, most of the magnetic flux that can be generated by the permanent magnets concentrates in the space between the two permanent magnets, so that the fuel oil passing through the space between the two permanent magnets is You will surely come into contact with more magnetic flux. On the other hand, also in the invention according to claim 3, since the two adjacent permanent magnets are arranged in a repulsive relationship with each other, the magnetic fluxes generated by the permanent magnets repel each other to escape to the outside. However, because of the nature of the magnetic flux, it always returns to the poles of the permanent magnets, so there are many magnetic fluxes in the space between the two permanent magnets, and the space between the two permanent magnets. Fuel oil passing through will surely come into contact with many magnetic fluxes.

According to the invention of claim 4,
If the i-th permanent magnet and the i + 1-th permanent magnet are in an attracting relationship, the i + 1-th permanent magnet and the i + 2-th permanent magnet are in a repulsive relationship, and thus the operation of the invention according to claim 1 has been described. The fuel oil moves between the space between the two permanent magnets → the opening → the space between the two permanent magnets → the opening → the space between the two permanent magnets → the opening… Then, the fuel oil alternately receives the parallel magnetic flux between the two permanent magnets having the attraction relationship and the magnetic flux escaping to the outside between the two permanent magnets having the repulsion relationship. Then, the molecules of the fuel oil are repeatedly magnetized from various directions while moving as described above, and therefore, friction is further generated inside the molecules rather than being always magnetized from the same direction. The atomization of molecules is surely performed.

When the side plate of the casing is made of a non-magnetic material as in the fifth aspect of the invention, the magnetic flux between the permanent magnets does not escape to the side plate of the casing, and as much magnetic flux as possible is generated by the fuel. It will be spent on the magnetization of oil. Further, in the invention according to claim 6, since the magnetic flux generated by the permanent magnet is increased by the plate-shaped member arranged in contact with the flat surface of the permanent magnet, the fuel oil touches more magnetic flux. Like

In the invention according to claim 7,
As the fuel oil travels the longest distance possible while passing through the space between the two permanent magnets, make sure that the fuel oil touches the most magnetic flux possible. become. However, in the invention according to claim 7,
The best effect is obtained when exactly 180 degrees is shifted, but it is not necessary to exactly shift 180 degrees,
If they are deviated by 0 degree, substantially the same effect can be obtained. Therefore, a difference of about 10 degrees is within the allowable range.

In brief, the invention according to claim 8 realizes the same structure as the invention according to claim 2 by an electromagnet instead of a permanent magnet. That is, in the invention according to claim 8, when a current is applied to the coil of the electromagnet that surrounds the outer peripheral surface of the casing side plate, the casing side plate is made of a non-magnetic material, so that it is further inside. A plate-shaped member made of a magnetic material is provided as a core of the electromagnet. Therefore, a large number of magnetic fluxes are present in the space sandwiched by the plate-shaped members serving as the cores.

Since the plate-shaped member arranged in the casing and the inner surface of the casing are sealed with a part of the opening left, a space sandwiched between two adjacent plate-shaped members. Communicate with each other through the opening. The communication state between the spaces sandwiched by such plate-like members is continuous from the upstream to the downstream of the fuel oil passage inside the casing, and the openings of adjacent plate-like members overlap each other. Therefore, the fuel oil inside the casing is sandwiched between the space between the two plate-like members → the opening → the two plate-like members, as in the invention according to claim 1 described above. Space → opening → space between two plate-shaped members → opening ... and so on.

Therefore, when the fuel oil moves in the casing as described above, the fuel oil passes through the space having the highest magnetic flux density, so that the fuel oil surely comes into contact with many magnetic fluxes. And, in the invention according to claim 9,
When the fuel oil passes through the space between the two plate-like members, it travels the longest distance possible, so the fuel oil surely contacts the most magnetic flux as much as possible. Like In the invention according to claim 9 as well, similar to the invention according to claim 7, the best effect is obtained when exactly 180 degrees are shifted, but exactly 1
It is not necessary to shift 80, and substantially the same action can be obtained if it is shifted by about 180 degrees. Therefore, a difference of about 10 degrees is within the allowable range.

[0022]

Embodiments of the present invention will be described below with reference to the drawings. 1 to 6 are views showing a first embodiment of the present invention, and FIG. 1 is a front sectional view of a fuel oil reforming apparatus 1. This fuel oil reforming apparatus 1 has a cap 4 on both ends of a cylindrical member 3.
The main body is a hollow casing 2 formed by fixing A and 4B. Female threads are formed on the inner peripheral surfaces of both ends of the cylindrical member 3, and male threads that are screwed into the female threads of the cylindrical member 3 are formed on the outer peripheral surfaces of the caps 4A and 4B. Are integrated by screwing them with female and male screws. However, by applying, for example, a sealant between the female screw and the male screw, the cylindrical member 3 and both caps 4A and 4B are in close contact with each other so that liquid leakage does not occur. Here, the cylindrical member 3 constitutes the side plate of the casing 2 in the present invention.

Nozzles 5A and 5B for communicating the inside and outside of the casing 2 are fixed to the caps 4A and 4B, respectively. That is, each of the nozzles 5A and 5B is a cylindrical body in which the base end portion 5a is formed to have a large diameter, and the shaft portion 5b continuous to the base end portion 5a is formed with a male screw.
After inserting the base end portion 5a from the inside of the casing 2 until the base end portion 5a abuts on the inside of the end surfaces of the caps 4A and 4B, into the through hole 4a opened at a position slightly eccentric to the end surface of B, the shaft portion 5 is inserted from the outside.
By fastening the nut 5c to b, the cap 4A,
It is fixed to 4B. However, these caps 4A,
For example, a sealant (not shown) is applied to the inner surface of the through hole 4a so that liquid leakage or the like does not occur between the nozzle 4A and the nozzles 5A and 5B.

As will be described later, a plurality of disc-shaped discs (having a pole in the axial direction (left and right direction in FIG. 1) and having a diameter smaller than the inner diameter of the casing 2 are formed in the casing 2 forming the fuel oil passage. In this embodiment, 10 permanent magnets 10,
10, ..., 10 are arranged in a state in which the planes face each other at a predetermined distance and are aligned from the cap 4A to the cap 4B.

Specifically, the permanent magnets 10, 10, ...,
Reference numeral 10 is formed in a ring shape with its central portion removed, and one side of each permanent magnet 10 has a substantially circular shield plate 1 formed by punching out a magnetic material, for example, a zinc iron plate.
1 is attached coaxially. The permanent magnet 10 and the shielding plate 11 are integrated by the magnetic force of the permanent magnet 10, but an adhesive may be applied between them to firmly integrate them.

The permanent magnet 10 may be a general ferrite magnet, but in order to enhance the fuel reforming effect, a strong permanent magnet such as a samarium-cobalt rare earth magnet is used. Is desirable. And
The shielding plates 11 are arranged in a state in which they face the same side and are held at a distance from each other by a cylindrical spacer 12, and the nuts 13a are fastened to both ends of the screw shaft 13 after passing through the centers thereof by the screw shaft 13 to be integrated. By inserting the whole thus integrated into the cylindrical member 3 before fixing the caps 4A and 4B, and then fixing the caps 4A and 4B to the cylindrical member 3 as described above. A plurality of permanent magnets 10 are arranged in the casing 2 with their planes facing each other while being held at a predetermined distance.

Here, as shown in FIG. 2, which is an enlarged sectional view taken along line II-II of FIG. 1, the screw shaft 13 has a circumferential direction of approximately 90 °.
Axial continuous spline groove 13 at 4 points apart from each other
b is formed. That is, the screw shaft 13 is a spline shaft. On the other hand, each shielding plate 11 has a maximum diameter within a range in which it can be inserted into the casing 2, and as shown in an enlarged view in FIG. 3 which is a plan view thereof,
A through hole 11a that is aligned with the spline groove 13b of the screw shaft 13 is opened in the central portion thereof. Therefore, the shielding plate 11
Is not rotatable with respect to the screw shaft 13.

A fan-shaped opening 11b having a width of about 60 degrees is formed in each shielding plate 11 by cutting off a part of the edge thereof. Therefore, when the permanent magnets 10, the shielding plates 11 and the spacers 12 are integrated into each other through the screw shafts 13 and then inserted into the casing 2, the outer peripheral surface of each permanent magnet 10 and the inner peripheral surface of the casing 2 are The shielding plate 11 is sealed while leaving the opening 11b.

Further, in this embodiment, the shield plates 1 adjacent to each other are used.
The shield plate 11 is attached to the screw shaft 13 so that the opening 11b is located on the opposite side with respect to the screw shaft 13 between the screw shafts 13, that is, the openings 11b are displaced from each other by 180 degrees in the circumferential direction. The nozzles 5A and 5B attached to the caps 4A and 4B are fixed at eccentric positions because the nozzles 5A and 5B are fixed to the caps 4A and 4B.
If the screw shaft 13 is located at the center of B, the nozzles 5A and 5B may be sealed by the screw shaft 13 when the screw shaft 13 is displaced in the axial direction due to vibration or the like. This is because

Moreover, in this embodiment, the nozzles 5A, 5B are
By utilizing that the eccentric position is fixed, the screw shaft 13
And each permanent magnet 10 fixed to this, each shield plate 1
1 and each spacer 12 are positioned. Specifically, the length of the screw shaft 13 is made equal to that of the cylindrical member 3, and when the caps 4A and 4B are fixed to the cylindrical member 3, the edge portions of the base end portions 5a of the nozzles 5A and 5B are screwed. The shaft 13 is in contact with both end faces of the shaft 13. In other words, the screw shaft 13 is positioned by sandwiching the screw shaft 13 with the nozzles 5A and 5B from both ends, thereby preventing the axial movement thereof.

The permanent magnets 10 are arranged such that the N poles and the S poles face each other so that the adjacent permanent magnets 10 have an attracting relationship, and the adjacent permanent magnets 10 have a repulsive relationship. It is possible to employ an arrangement in which the N poles face each other and the S poles face each other so as to achieve the above, and an arrangement in which the suction relation and the repulsion relation are alternately repeated. However, it is desirable to make the magnetic flux density of the space between the two permanent magnets 10 as high as possible regardless of which arrangement relationship is adopted.

In order to satisfy such requirements, in this embodiment, the cylindrical member 3 is made of a non-magnetic material such as stainless steel. That is, when each of the permanent magnets 10 is in the attraction relationship, if the cylindrical member 3 is made of a non-magnetic material, most of the magnetic flux (represented by the broken line) is generated as shown in FIG.
Runs straight between the permanent magnets 10 without escaping to the cylindrical member 3 side, so the magnetic flux density between the permanent magnets 10 becomes extremely high in a possible range.

Similarly, when the cylindrical members 3 are made of a magnetic material when the permanent magnets 10 are in a repulsive relationship, FIG.
As shown in FIG. 5, since the magnetic fluxes that repel each other and try to spread outward do not escape to the cylindrical member 3, the magnetic flux running inside the casing 2 increases accordingly. In the case where the attraction relationship and the repulsion relationship are alternately repeated, the magnetic flux states of the attraction relationship and the repulsion relationship are alternately repeated, and therefore, the magnetic flux density between the permanent magnets 10 is extremely large in a possible range. Get higher

In the fuel oil reforming apparatus 1, for example, when the cap 4A is located upstream, fuel oil such as light oil is supplied from the nozzle 5A into the casing 2, and the casing 2 moves as a passage to reverse. The fuel oil that has reached the side is nozzle 5
The fuel oil may be discharged to the outside via A, and the discharged fuel oil may be supplied to, for example, a fuel supply port of a diesel engine.

That is, the fuel oil that has flowed into the casing 2 through the nozzle 5A is shielded on the most upstream side, as shown by the solid arrow in FIG. 5, which simply shows the internal structure of the fuel oil reforming apparatus 1. It flows into the space sandwiched between the first permanent magnet 10 and the second permanent magnet 10 through the opening 11a of the plate 11, moves diametrically across the space, and moves to the next shielding plate 11 It reaches the opening 11a, flows into the space sandwiched by the second permanent magnet 10 and the third permanent magnet 10 through the opening 11a, and moves so as to cross the space in the orthogonal direction. Next opening 1 of the shielding plate 11
1a, through the opening 11a, and so on, and finally through the space inside the cap 4B through the nozzle 5B to the outside of the casing 2, and then supplied to the diesel engine and the like.

As shown by the broken line in FIG. 4 (a) or 4 (b), the space between the permanent magnets 10 has a particularly high magnetic flux density. Therefore, when passing through the space, the fuel oil becomes a magnetic flux. Friction occurs inside the molecules when touched, and the effect of reforming the molecules of the fuel oil is obtained. Then, as compared with the case where the molecules are not atomized, combustion becomes easier, that is, incomplete combustion is less likely to occur, so that the calorific value increases correspondingly and fuel efficiency is improved, and incomplete combustion occurs. Further, for example, in the case of light oil, the generation of substances that cause pollution such as nitrogen oxides can be suppressed.

In particular, when the permanent magnets 10 are arranged such that the relationship between the adjacent permanent magnets 10 alternately repeats the attraction relationship and the repulsion relationship, the fuel oil moving in the casing 2 is The magnetic flux extending in the direction parallel to the axis as shown in FIG. 4A and the magnetic flux extending in the direction orthogonal to the axis as shown in FIG. 4B are alternately touched. Then, the fuel oil molecules are repeatedly magnetized from various directions.
As shown in (b), since friction is further generated inside the molecule and atomization of the molecule is performed more reliably than when always magnetized from the same direction, the fuel oil can be reformed very efficiently. .

Further, in the fuel oil reforming apparatus 1 of this embodiment, the permanent magnet 10 attached to the shield plate 11 is attached to the screw shaft 13.
After passing a predetermined number of spacers and spacers 12 alternately, both ends of the screw shaft 13 are fastened by nuts 13a to integrate them, and the integrated product is inserted into the cylindrical member 3 of the casing 2. Assembling can be completed by fixing the caps 4A and 4B. Moreover, the opening 1
Except for the circumferential position of 1b, each permanent magnet 10 and its periphery have the same shape, and the circumferential position of each shielding plate 11 has a spline groove 13b formed in the screw shaft 13 and a through hole 11a formed therein.
Since they are fixed by aligning them, no alignment is required when inserting the above-mentioned integrated object into the cylindrical member 3, and even if the permanent magnet 10 rotates inside after being assembled, the flow path Is not closed, and the axial position of the screw shaft 13 is the same as the caps 4A and 4B.
Since it is fixed by being connected to the
It is not necessary to fix the outer peripheral surface of 1 to the cylindrical member 3 with an adhesive, welding, or the like.

From the above, according to the structure of this embodiment, although the movement of the fuel oil can be complicated, the manufacturing process is complicated and the cost is greatly increased. There is no. The most suitable application method of the fuel oil reforming apparatus 1 as in this embodiment is to directly intervene in a fuel oil supply line of a diesel engine of a vehicle, for example. The reason is that the theoretical elucidation has not been completely completed, but the experimental results show that the shorter the time from the magnetization process to the burning, the better the complete burning rate. is there.

Therefore, for example, if the cap 4A side is upstream, light oil is supplied to the nozzle 5A from the fuel tank, and light oil that passes through the casing 2 and is discharged from the nozzle 5B is supplied to the fuel oil supply port of the diesel engine. do it.
However, when applied to a vehicle that consumes a relatively large amount of fuel, such as a large-sized trailer, the fuel oil reforming apparatus 1 is designed in consideration of the amount of fuel oil consumed by the engine per unit time.
It is necessary to decide the capacity of.

For example, assuming that the fuel consumption of a large trailer is 2 liters / km and that the vehicle travels at an average speed of 60 km / hour, 30 liters / hour and 0.5 liter / minute of fuel oil will be consumed. . If the time required for sufficient reforming is 7 minutes, the fuel oil reforming apparatus 1 needs an internal space for storing 3.5 liters of fuel oil.

Here, assuming that the fuel oil is magnetized in the space sandwiched by the permanent magnets 10 and is not magnetized in the other spaces, the thickness of each permanent magnet 10 is 10 mm, and the distance between the permanent magnets 10 is 10 mm. Is 10 mm, the casing 2 needs to have a volume of 7 liters or more. For example, if the diameter of the permanent magnet 10 is 50 mm, the total length of the fuel oil reforming apparatus 1 is about 3.57 m. Similarly, if the distance between the permanent magnets 10 is 15 mm, the total length of the fuel oil reforming apparatus 1 is about 2.98 m.
Therefore, if the distance between the permanent magnets 10 is 20 mm, the total length of the fuel oil reforming apparatus 1 is about 2.68 m.

As described above, the shorter the distance between the permanent magnets 10 is, the larger the magnetizing force is. Therefore, the smaller the distance is, the more advantageous it is. On the other hand, the volume of the fuel oil reforming apparatus 1 is increased. There is a drawback that the device becomes large. If the fuel oil reforming apparatus 1 is actually used by being mounted on a vehicle or the like, it is preferable that its size is as small as possible. However, as a result of appropriately selecting the strength of the permanent magnets 10, the distance between the permanent magnets 10 is increased. Even if the distance can be set to 15 mm, the total length of the fuel oil reforming apparatus 1 is close to 3 m, and it is difficult to mount the fuel oil reforming apparatus 1 on a vehicle with a small space.

Therefore, in consideration of mountability on a vehicle, FIG.
It is preferable to have a structure as shown in (a) and (b). 6A is a left side view, and FIG. 6B is a partially cutaway front view. That is, a plurality of (nine in this example) fuel oil reforming devices 1 are housed in a substantially rectangular parallelepiped casing 20 in a state of being stacked vertically and horizontally, and the nozzles 5A, 5B of the fuel oil reforming devices 1 are connected to each other. , 21 are sequentially connected to form a single flow path by the plurality of fuel oil reforming apparatuses 1.

Specifically, after housing the individual fuel oil reforming apparatus 1 in the casing 20, only the nozzles 5A and 5B of the fuel oil reforming apparatus 1 are exposed to the outside of the casing 20 at both ends of the casing 20. Is sealed with a lid 20a.
Then, assuming that these nine fuel oil reforming apparatuses 1 are shown in FIG.
As shown in FIG. 6A, the left side of the uppermost stage is numbered 1, the center is numbered 2, the right side is numbered 3, and the right side of the lowermost stage is numbered 9.
If the nozzle 5A faces the visible side in (a) and the nozzle 5B desires on the opposite side, the first nozzle 5B and the second nozzle 5B, the second nozzle 5A and the third nozzle 5A,
No. 3 nozzle 5B, No. 6 nozzle 5B, No. 6 nozzle 5
A and No. 5 nozzle 5A, No. 5 nozzle 5B, No. 4 nozzle 5B, No. 4 nozzle 5A, No. 7 nozzle 5A, No. 7 nozzle 5B, No. 8 nozzle 5B, No. 8 nozzle 5A 9
Nozzle 5A, and so on.

The fuel oil reforming apparatus 1 integrated in this way
A bracket 20b provided on the outer surface of the casing 20
As shown in FIG. 7, the fuel tank 22
And the diesel engine 23 may be interposed.
Specifically, the other end of the pipe 24 having one end inserted into the fuel tank 22 is connected to the nozzle 5A of the first fuel oil reforming apparatus 1 described above, and the one end is a suction port of the suction motor 25. The other end of the pipe 26 connected to is connected to the nozzle 5B of the fuel oil reformer 1 of No. 9 described above.

Then, the light oil in the fuel tank 22 is supplied from the fuel tank 22 through the pipe 24 to the fuel oil reforming apparatus 1 in the casing 20 by the suction force of the suction motor 25, where each fuel oil reforming is performed. Piping 26 through all devices 1
Since it is supplied to the diesel engine 23 through the suction motor 25 and the filter 27, the light oil sufficiently reformed by the plurality of fuel oil reforming devices 1 in the case 20 is always supplied to the diesel engine 23. As a result, it is possible to obtain the effects of improving fuel efficiency and suppressing the generation of nitrogen oxides.

As shown in FIGS. 6 (a) and 6 (b), if a plurality of fuel oil reforming apparatuses 1 are combined to form one fuel oil reforming apparatus, the above-described fuel oil reforming for a large trailer is performed. About 30 cm compared to about 3 m in quality device 1
Since it can be accommodated in the casing 20 having a size of about x30 cm x30 cm, it can be sufficiently mounted on a vehicle. Figure 8
It is a figure which shows the 2nd Example of this invention, Comprising: It is a front sectional view of the fuel oil reforming apparatus 1 like FIG. 1 of the said 1st Example. The same members and parts as those in the first embodiment are designated by the same reference numerals, and their duplicated description will be omitted.

That is, in this embodiment, instead of the permanent magnet 10 used in the first embodiment, a plurality of plate-like members formed in the same shape as the permanent magnet 10 and made of a magnetic material such as iron. 30 are provided at the same position, and a plurality of electromagnet coils 31, ..., 3 are provided so as to surround the cylindrical member 3.
1 is provided. Specifically, each of the coils 31 is wound around the outer circumference of a bobbin 31a made of a non-magnetic material, and the bobbins 31a in the wound state of the coils 31 are arranged in the cylindrical member 3 in the axial direction. It is fitted on.
However, each bobbin 31a has a thickness equal to the sum of the thickness of the plate-shaped members 31 and the distance between the plate-shaped members 31. It is adapted to be accommodated in a position surrounding the outer peripheral surface of the strip-shaped member 30. A cylindrical case 32 is fitted on the outer side of the coil 31.

Each coil 31 is connected to a power source such as a battery (not shown). For example, in the case of the fuel oil reforming apparatus 1 mounted on a vehicle, each coil 31 is generated when the engine is driven. Direct currents in the same direction are supplied so that the directions of the magnetic flux match, and the current to the coil 31 is cut off when the engine is not driven. In addition, each coil 31 may be configured such that the ends of adjacent ones are connected to each other so as to be composed of one conductor as a whole.

Here, the cylindrical member 3 of this embodiment is not made of a magnetic material such as iron but is made of a non-magnetic material such as stainless steel. With the above configuration, when a current is supplied to each coil 31, a magnetic field is generated inside the coil 31, but the plate-shaped member 30 made of a magnetic material is disposed in the casing 2, and Since there is no member made of magnetic material between the coil 31 and the plate-shaped member 30, these plate-shaped members 3
A large number of magnetic fluxes are generated so as to penetrate between 0 front and back surfaces.

Therefore, in the first embodiment, the situation is the same as in the case where the permanent magnets 10 are arranged in an attracting relationship. Therefore, fuel oil such as light oil is passed through the fuel oil reforming apparatus 1 before the diesel. If it is supplied to the engine, the same reforming effect of the fuel oil can be obtained, so that incomplete combustion is less likely to occur, and effects such as improvement of fuel consumption and suppression of generation of nitrogen oxides can be obtained.

In this embodiment, the coil 30
By adjusting the number of turns, the value of the current supplied to the coil 30, and the like, the strength of the electromagnet can be adjusted, so that the reforming effect can be arbitrarily adjusted. Therefore, when used in vehicles, for example, fuel oil consumption per unit time (can be estimated from engine speed, etc.)
If the current value supplied to the coil 30 is adjusted in proportion to, it is possible to obtain a sufficient reforming effect while suppressing the current consumption to the minimum.

If an electromagnet is used, a magnet that is about 3 to 4 times stronger than a ferrite magnet can be easily made.
It becomes possible to make it 3-1 / 4, which is advantageous when there is a small space in the mounting space such as a vehicle. In addition,
Also in the case of the second embodiment, in order to prevent the overall length of the fuel oil reforming apparatus 1 from becoming too long, as shown in FIG. 6 of the first embodiment, a plurality of fuel oil reforming apparatuses are provided. 1 may be integrated and used. The mounting condition on the vehicle is
This is the same as that shown in FIG. 7 of the first embodiment.

Further, in this second embodiment, each coil 31
Although a direct current is supplied to the above, an alternating current may be used instead of the direct current. However, even in that case, for example, it is necessary to always generate magnetic flux in the same direction by connecting the coils 31 adjacent to each other to form a coil actually composed of one conductor. The member 3 needs to be made of a non-magnetic material.

Further, if the direction of the direct current can be switched and the direct current whose direction is reversed at an arbitrary predetermined time interval (for example, one second interval) is supplied to the coil 31, fuel oil can be supplied. Is given a magnetic field whose direction changes alternately, so that the components of the fuel oil are alternately magnetized in different directions at predetermined intervals, causing friction inside the molecule and making the molecule atomize more reliably. Become. In addition,
Even when an alternating current is supplied to the coil 31, if the cycle is longer than the magnetization reaction speed of the fuel oil, the same effect can be expected.

FIG. 9 is a diagram showing a third embodiment of the present invention, and the fuel oil reforming apparatus 1 is the same as FIG. 1 of the first embodiment.
FIG. The same members and parts as those in the first embodiment are designated by the same reference numerals, and their duplicated description will be omitted. That is, in this embodiment, each permanent magnet 10 is made of a material having a magnetic permeability higher than that of the material of the permanent magnet 10 (for example,
While being attached to a relatively thick shield plate 35 made of pure iron or the like and with a spacer 12 keeping a predetermined distance, the hollow shaft 36 is externally fitted to the outer surface of the permanent magnet 10 located at both ends. By pressing a pressing plate 37 having the same material and planar shape as the shielding plate 35, and further penetrating the shaft 36 and both pressing plates 37 with a shaft 38, and attaching snap rings 39 to both ends of the shaft 38, The permanent magnet 10 and the shielding plate 35,
They are integrated with their planes facing each other at a predetermined distance. Here, the shielding plate 35 and the pressing plate 37 correspond to the plate-like member in the invention according to claim 6.

Then, the thus integrated one is
The caps 4A and 4B are inserted into the cylindrical member 3 before being fixed, and then the caps 4A and 4B are press-fitted from both openings of the cylindrical member 3 so that the pressing plates 37 are sandwiched from both sides by their edge portions, and are permanently attached. The magnet 10 and the shielding plate 35 are arranged inside the casing 2. In this embodiment, the cylindrical member 3
The two caps 4A and 4B are closely integrated by welding their joint surfaces.
A notch 4d is provided in a part of the edges of A and 4B to secure a passage for fuel oil.

As shown in FIG. 10 which is a plan view of each of the shielding plates 35 of this embodiment, each shielding plate 35 is also formed in a circular shape so that it can be fitted to the inner peripheral surface of the cylindrical member 3, but a part of the edge thereof. Is cut off along a straight line to form the opening 35b. Then, as shown in FIG. 9, between the adjacent permanent magnets 10, the openings 35b are located on the opposite sides of the shaft 38, that is, the openings 11b are displaced from each other by 180 degrees in the circumferential direction. A shield plate 35 is attached to the shaft 36.

Further, in this embodiment, since the caps 4A and 4B are brought into contact with the outside of the pressing plate 37 to prevent the shafts 36 and 38 from moving in the axial direction,
It is not necessary to eccentrically install the nozzles 5A and 5B.
Therefore, the nozzles 5A and 5B are attached to the central portions of the caps 4A and 4B. In this embodiment, a seal ring 40 is interposed between the large diameter portion 5a of the nozzle 5A, 5B and the inner bottom surface of the cap 4A, 4B in order to prevent the liquid from leaking more reliably.

Here, also in the present embodiment, the arrangement of the permanent magnets 10 is such that the adjacent magnets are in an attracting relationship, the adjacent magnets are in a repulsive relationship, the attractive relationship and the repulsive relationship. An arrangement that repeats alternately can be considered, but it is desirable to adopt an arrangement that repeats the suction relationship and the repulsion relationship that can perform the most efficient reforming. Even with such a configuration, the fuel oil supplied into the casing 2 through the nozzle 5A has the two permanent magnets 1 as in the first embodiment.
By alternately passing through the space sandwiched by 0s and the opening portion 35b, the nozzle reaches the nozzle 5B on the downstream side and is discharged to the outside of the casing 2 from the nozzle, so that the same effect as the first embodiment is exhibited. To be done.

Moreover, in this embodiment, each permanent magnet 10 is used.
In addition, the shielding plate 35 and the pressing plate 3 made of a material having high magnetic permeability.
Since 7 are in contact with each other, the effect that the density of the magnetic flux generated by the permanent magnet 10 becomes higher than that when the permanent magnet 10 is used alone. That is, it is possible to obtain the same operational effect as using a stronger permanent magnet. Therefore, if the same permanent magnet 10 is used, the effect of reforming the fuel oil is further improved as compared with the first embodiment, so that the effects of improving fuel efficiency and suppressing the generation of nitrogen oxides are increased.

In each of the above embodiments, the openings 11b are shifted 180 degrees between the adjacent shield plates 11. However, a sufficient effect can be expected even if they are not exactly 180 degrees apart. For example, a difference of about 10 degrees can be tolerated. Further, in each of the above embodiments, the permanent magnet 10 or the plate-shaped member 30 has a circular shape, but the present invention is not limited to this. For example, a rectangular plate-shaped permanent magnet or a plate-shaped member may be used. The number of sheets is not limited to the number shown in the above embodiment, and may be more or less. The casing 2 is not limited to the cylindrical shape, and may be, for example, a rectangular parallelepiped.

The fuel oil that can be reformed is not limited to light oil, but may be another fuel oil such as gasoline, and the fuel oil reforming apparatus 1 can be applied directly to a vehicle. The fuel oil is not limited to being mounted, and may be attached to, for example, a fuel oil storage tank and the fuel oil in the tank may be circulated through the fuel oil reforming apparatus 1.

[0065]

As described above, according to the first aspect of the invention, the fuel oil is moved as a flow path in the space sandwiched by the permanent magnets, so that the fuel oil is magnetized very efficiently. Therefore, there is an effect that the modifying effect can be significantly improved. According to the second, third, and fourth aspects of the invention, since many magnetic fluxes exist between the permanent magnets, the fuel oil comes into contact with the many magnetic fluxes to obtain a high reforming effect. be able to.

In particular, according to the invention of claim 4, since the fuel oil is repeatedly magnetized from various directions, there is an effect that the reforming effect can be further improved. On the other hand, in the invention according to claim 5, since the magnetic flux does not escape to the side plate of the casing, a large number of magnetic fluxes can be present inside the casing by that amount, and thus a higher reforming effect can be obtained. .

Further, in the invention according to claim 6, since the magnetic flux density between the permanent magnets can be increased as compared with the case where the permanent magnet is used alone, the effect of reforming the fuel oil is further improved. The effect that can be obtained is obtained. Even in the invention according to claim 8, the same effect as that of the invention according to claim 2 can be obtained, and since the strength as an electromagnet can be adjusted, the modifying effect can be arbitrarily adjusted. In addition, the electromagnet can be made stronger, which makes it easier to downsize the device.

Further, in the invention according to claim 7 or claim 9, when the fuel oil passes through the space sandwiched between the two permanent magnets or the two plate-shaped members, it is the longest possible. Since the fuel oil moves over a distance, the fuel oil can surely come into contact with the largest amount of magnetic flux in a possible range, so that the reforming effect is further improved.
