Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention has an object to obtain a fuel magnetic field treatment apparatus for improving the combustibility of diesel internal combustion engines and other light and heavy oils.

[0002]

2. Description of the Related Art Techniques for improving the fuel consumption rate and the exhaust gas by magnetically treating a fuel for an internal combustion engine are known (Japanese Patent Laid-Open Nos. 64-56954, 64-56955, and 64-56955). 64-56956, JP-A-64-56957,
JP-A-64-56958, JP-A-2-301657
No. 2, JP-A-2-301658 and JP-A-2-30165.
No. 9).

However, the above technique has a problem that the improvement efficiency is low because the magnetic flux density per unit length of the fuel flow path is relatively coarse.

[0004]

SUMMARY OF THE INVENTION It is an object of the present invention to take in a large amount of magnetic flux into a passage having a short passage resistance and a short passage resistance of fuel to improve magnetic treatment efficiency.

[0005]

In order to achieve the above object, the present invention has a plurality of hollow large-diameter permanent magnets stacked in a short cylinder, and a plurality of small-diameter permanent magnets inside the large-diameter permanent magnet. Are arranged in a stack, the large diameter and small diameter magnets are supported on a common center line, and a fuel passage gap is provided between the inner circumference of the large diameter permanent magnet and the outer circumference of the small diameter permanent magnet. The lower surface of the magnet and the upper surface of the lower magnet have the same pole, and are constituted by a fuel magnetic field processing device in which they are contact-supported against the repulsive force.

[0006]

In the present invention, the oil feed pipe 6 is provided from the fuel tank 4 to the internal combustion engine 5 via the fuel pump, and the short pipe 1 is provided in the oil feed pipe 6 to pass the fuel through the fuel passage gap t.

In the gap t, magnetic fluxes from the inner circumference of the hollow large-diameter permanent magnet 2 and the outer circumference of the small-diameter permanent magnet 3 to the magnets 2, 2, 3 and 3 in the upper and lower stages are independently directed from the N pole to the S pole. Occurs and the magnetic flux density almost doubles. That is, since the upper N pole and the lower N pole are in contact with each other, magnetic flux is independently generated in each stage.

Further, the gap t is defined by the large-diameter permanent magnets 2 in the upper and lower stages.
Since the two are in contact with each other and the small-diameter permanent magnets 3 are in contact with each other, the inner wall has no unevenness and the flow rate per unit time increases.

[0009]

EXAMPLE A plurality of hollow large-diameter permanent magnets 2 are fitted and stacked in a short cylinder 1 made of a non-magnetic material with N poles or S poles facing each other, and a plurality of hollow small diameters are provided inside the permanent magnet 2. The permanent magnets 3 are arranged in a stack with their N poles or S poles facing each other, and a spindle 6 concentric with the short cylinder 1 is fitted inside the small diameter permanent magnet 3.

On the upper and lower surfaces of the stacked permanent magnets 2 and 3 and the support shaft 6, contact plates 7 and 7 which are fitted to the inner peripheral surface of the short cylinder 1 are arranged, and the corresponding plates 7 and 7 are pressed in opposite directions. As a result, the upper and lower magnets 2, 2 and 3, 3 are brought into pressure contact with each other, and the set screws 9, 9 are inserted from the central through holes 8, 8 of the corresponding plates 7, 7 into the central screw holes 6 ', 6'of the support shaft 6. The permanent magnets 2, 2 and 3 in the upper and lower stages are screwed together.
Hold 3 in contact and on common centerline c.

A fuel passage gap t is provided between the inner circumference of the large-diameter permanent magnet 2 and the outer circumference of the small-diameter permanent magnet 3, and the stacked permanent magnets 2, 2 and 3 are located in the gap t. 3 generates magnetic lines of force independently in the upper and lower stages.

A fuel passage hole 10 is formed in the contact plates 7, 7 along the gap t, and the contact plates 7, 7 are pressed by the lids 11, 11 screwed onto the upper and lower portions of the short cylinder 1. To support. Lid 1
1 and 11 have a space s communicating with the passage hole 10, the inflow nozzle 12 and the outflow nozzle 13 are communicated with the space s, s, and the oil feed pipe 6 is connected to these nozzles 12 and 13.

Since the present invention is configured as described above, although the passage resistance of the fuel passage gap t is small and the fuel passage can be performed quickly, the magnetic flux is concentrated in the gap t and the magnetic flux density is almost doubled. It is possible to smoothly and quickly pass through the gap t having a high magnetic flux density, and it is possible to improve the magnetic treatment efficiency of the fuel.
