Description

  The present invention relates to a fuel reforming method, and more particularly to a method capable of greatly improving the combustion efficiency of hydrocarbon fuel.

  Various hydrocarbon fuels such as gasoline, light oil, heavy oil, etc. are used in engines for vehicles and ships. This hydrocarbon fuel is generally considered to have van der Waals bonds with fuel molecules having a particle size of about 50 μm to 100 μm. In such a state where the fuel molecules are combined, the contact efficiency with oxygen is poor, It is said that complete combustion is likely to occur.

  On the other hand, a method has been proposed in which fuel is passed through a magnetic field in a fuel supply system, the bonds of fuel molecules are cut and atomized, and combustion efficiency is increased (for example, Patent Document 1, Patent Document 2, Patent). Reference 3, Patent Document 4, Patent Document 5, etc.).

  Fuel that atomizes fuel molecules by the magnetic treatment described above can reduce fuel consumption, reduce emissions of nitrogen oxides (NOx) and carbon monoxide, and, in the case of diesel engines, black smoke in the exhaust gas. It has been reported that this can be reduced.

  However, when the fuel is atomized by magnetic processing, the effect of the magnetic processing cannot be obtained unless the fuel moves at a speed of 2 m / sec or more in the magnetic field. However, the fuel is passed through the magnetic field in the fuel supply system. However, the actual situation was that the fuel flow rate was slow, the fuel was not sufficiently atomized, and only a few percent improvement in fuel consumption was obtained.

  In view of this, a method has been proposed in which a magnet is disposed in the fuel tank, the movement of the fuel in the fuel tank during traveling is ensured to ensure movement of the fuel relative to the magnetic field, and the fuel is atomized (for example, (See Patent Document 6, Patent Document 7, Patent Document 8, etc.).

  However, although the conventional in-tank system has improved combustion efficiency as compared with a system in which it passes through a magnetic field, the actual situation is that only an improvement of less than 10% in fuel efficiency has been obtained.

  In view of such problems, the present invention has an object to provide a fuel reforming method capable of greatly improving combustion efficiency.

  Therefore, the fuel reforming method according to the present invention is configured so that at least two magnet bodies are as close as possible to each other so that magnetic fields repelling each other pass through the wall surface in the vicinity of the fuel supply port of the fuel tank. The fuel is provided on the bottom surface of the tank and crosses the magnetic fields repelling each other, and is sent out from the fuel delivery port.

  When the fuel is atomized by a magnetic field, it has been confirmed by experiments of the present inventors that the fuel needs to move in a sufficiently large magnetic field at a speed of 2 m / sec or more. In a conventional system in which a magnet body is provided in a fuel tank, even if the fuel in the tank moves at a speed of 2 m / sec or more and is atomized, the fuel tank does not pass until the fine fuel is delivered from the fuel tank to the engine. It is considered that the combustion efficiency could not be improved due to mixing with unreformed fuel.

  On the other hand, one of the features of the present invention is that magnetic fields repelling each other are made as close as possible to each other and magnetized to the bottom surface of the fuel tank to form a large magnetic field in the fuel tank. The fuel in the vicinity of the inlet is crossed.

  As a result, at least two magnetic fields are formed in the vicinity of the fuel supply port of the fuel tank, but these magnetic fields repel each other, so that the magnetic fields greatly expand on the opposite sides. As a result, the fuel in the vicinity of the fuel supply port is surely atomized across the magnetic field at a predetermined speed or more, and can be sent out from the fuel supply port as it is, so compared with the case where a magnet body is provided in the fuel tank. Thus, even with a magnet body having the same magnetic flux density, the fuel can be atomized more reliably, and the combustion efficiency can be greatly increased.

  The fuel reformer according to the present invention is a fuel reformer comprising at least two magnet assemblies magnetically attached to the bottom surface of the fuel tank, and each of the at least two magnet assemblies includes a magnet body. A structure in which the upper and lower layers are laminated with the ferromagnetic body on the lower side and the same magnetic pole surface of the magnet body is fixed to each other by a case, and the at least two magnet assemblies are as close as possible to each other The magnet body is magnetically attached to the bottom surface of the fuel tank.

  The reason why the ferromagnetic body is provided on the lower side of the magnet body is that the magnetic lines of force extend through the bottom wall of the fuel tank to the inside of the fuel tank due to the action of the ferromagnetic body, thereby forming a large magnetic field in the fuel tank. Because.

  Here, it was confirmed by experiments of the present inventors that the ferromagnetic material should be thicker than the bottom wall of the fuel tank. It was also confirmed that the ferromagnetic material should have a thickness approximately equal to or greater than that of the magnet body.

  In order to penetrate the magnetic lines of force to the inside of the fuel tank, the ferromagnetic body is preferably formed by laminating a plurality of ferromagnetic plates.

  In order to secure the maximum fuel reforming effect, the at least two magnet assemblies are preferably magnetically attached to the outer surface of the bottom wall facing the fuel supply port of the fuel tank. Even if magnetized, the fuel reforming effect superior to that of the conventional system can be obtained.

  Hereinafter, the present invention will be described in detail based on specific examples shown in the drawings. 1 to 4 show a preferred embodiment of a fuel reformer according to the present invention. In the figure, a magnet assembly 10 is configured by incorporating a magnet body 20 on the upper side and two steel plates (ferromagnetic plates) 30 on the lower side in a case 40 made of synthetic resin having an upper surface opened. .

  The magnet body 20 is a neodymium magnet having a magnetic flux density of 400000 μT (4000 G), and is provided in the case 40 so that the N pole is on the upper surface. Further, the thickness a of the two steel plates 30 is larger than the thickness 2.5 mm to 3 mm of the bottom wall of the fuel tank 50, the thickness a of the magnet body 20 and the thickness a of the two steel plates 30. Both are set to 4.5 mm to 5.0 mm.

  Two magnet assemblies 10 of this example are used as one set. When the magnet assembly 10 of this example is attached to the fuel tank 50, a pair of magnet assemblies 10, 10 are mutually attached to the outer surface of the bottom wall facing the front end opening (fuel supply port) of the suction hose 60 of the fuel pump. It is magnetically attached to the outer surface of the bottom wall of the fuel tank 50 while being as close as possible.

  Then, before magnetic attachment to the fuel tank 50, as shown in FIG. 4 (a), a large magnetic field line is formed above the upper surface N pole by the action of the two steel plates 30 in the magnet assembly 10. .

  As shown in FIG. 4B, when steel plates 80 having the same thickness are magnetized on the upper and lower sides of the magnet body 20, the magnetic lines of force are formed between the steel plates 80, 80, and the steel plate 80 It is not formed so as to penetrate greatly.

  However, since the thickness of the two steel plates 30 is larger than the thickness of the fuel tank 50 in the magnet assembly 10 of this example, when the magnet assembly 10 is magnetically attached to the outer surface of the bottom wall of the fuel tank 50, As shown in FIG. 4 (c), the magnetic lines of force are formed through the outer wall of the fuel tank 50 to the inside of the fuel tank 50.

  In addition, in this example, the two magnet assemblies 10 and 10 are made as close as possible to each other, so that the magnetic lines of force of the two magnet assemblies 10 repel each other as shown in FIG. Expands greatly to the other side.

  In such a state, when the vehicle travels, the fuel in the fuel tank 50 is sucked into the suction hose 60 and supplied to the engine. However, the fuel sways due to traveling and travels in the magnetic field at a speed of 2 m / sec or more. Since the particles are atomized across the magnetic field greatly expanded by the above and are sucked into the suction hose 60 as they are, the combustion efficiency is greatly improved.
