Definitions

  • the invention relates to an internal-combustion engine, more particularly, to a magnetization fuel-economizing device for an automobile fuel engine.
  • This method causes the fuel to flow through a magnetization device for fuel so as to improve the dispersed property and atomization level of the fuel which will bring about the fuel to combust sufficiently, thus to realize the aim of fuel saving.
  • a magnetization fuel economizer shown as Fig. 1, for an internal combustion engine said economizer comprising a housing (1) having a longitudinal through cavity, a tube connector (6, 7) possessing a flared flow passage and being hermetically disposed in each of the two ends of said through cavity whereby each tube connector is adapted to communicate with a fuel supply pipe, a magnetization cavity disposed perpendicular to the through cavity with two permanent magnets (2, 3) disposed in it with the magnetic poles of said magnets opposed each other whereby the greater dimension of said flared flow passage is directed towards the center of said longitudinal through cavity and whereby the interval between the two permanent magnets forms a fuel passing gap having a width, said width being measured in a direction perpendicular to the axis of said longitudinal through cavity and perpendicular to said opposed magnetic poles, and, in addition, a magnetic filter cavity arranged to communicate with said longitudinal through cavity and disposed parallel to the magnetization cavity with
  • the advantage of this utility model is that the permanent magnets have a higher magnetic energy product and a higher inherent coercitive force, which will cause fuel to combust sufficiently and to increase the output power of the engine through forming a stronger magnetization effect without having to superimpose a static electrical field. Meanwhile, the contents of carbon monoxide and hydrocarbons reduce, and the iron magnetic materials in the fuel will be less accumulated in the magnetic filter cavity by means of the adsorption of the magnet in this cavity.
  • An object of the invention is to provide a new structure of the magnetization fuel-economizer to improve the above mentioned structure, which can form a closed magnetic circuit in the fuel-economizer, thus to increase the magnetic field intensity and to further improve the magnetization effect of the fuel with the results that a high combustion efficency of the fuel can be obtained ; hence the output power of the engine may be enhanced to realize a fuel saving and a exhaust gas clean up. Meanwhile, the magnetic field intensity of the magnetic filter cavity can be increased enough such that the iron magnetic materials suspended in the fuel can be totally adsorbed on this cavity and do not jam up the cavity again.
  • the present invention provides in combination that said fuel gap has a width of 0,5-2,0 mm, and that the other ends of said opposed magnetic poles of said two permanent magnets in said magnetization cavity are provided respectively with magnetic circuit sheets to form a closed magnetic circuit, and that the one end of said permanent magnet in said magnetic filter cavity is provided with a magnetic circuit sheet and the other end of said permanent magnet is opposed to a magnet circuit sheet disposed on the wall surface of said magnetic filter cavity, said wall surface being in use the bottom surface of said magnetic filter cavity, thus to form a fixed fuel passing gap between said permanent magnet and said magnetic circuit sheet, and to form a closed magnetic circuit.
  • housing is denoted by the reference numeral 1, which is made of aluminum alloy.
  • the housing 1 has a longitudinal and circular through cavity, and the inner walls of the two ends of the cavity are formed with inner threads.
  • the housing 1 has formed on it a magnetic filter cavity and a magnetization cavity, and the two cavities are all perpendicular to and communicated with the longitudinal cavity.
  • the two ends of the through cavity are joined hermetically with tube connectors 13 and 14 respectively.
  • the tube connectors are made of aluminum alloy or brass.
  • the inner flow passage of the tube connectors is shaped as one end to be a flare expanded outwardly and to connect with the fuel-economizer, and the other portion of the tube connector formed as a straight tube communicates with a fuel supply pipe, a carburetor or a fuel injection pump.
  • the magnetization cavity is a circular hole perpendicular to the through cavity, with two permanent magnets 3 and 4 disposed in it with their magnetic poles opposed each other.
  • a fuel passing gap with a width of 0.5 ⁇ 2.0 mm (measured in a direction perpendicular to the axis of the longitudinal through cavity and perpendicular to the opposed magnetic poles) is formed between permanent magnets 3 and 4, which may oppose each other with the N pole to N pole, or S pole to S pole, or N pole to S pole, and have the magnetic circuit sheets 7 and 8 disposed on the other ends of the opposed magnetic poles of the magnets 3 and 4 respectively, so that a closed magnetic circuit is formed.
  • the magnetic filter cavity is a stepped hole communicating with the longitudinal through cavity of the housing 1 and the surface of the housing 1.
  • a permanent magnet 2 is mounted in the magnetic filter cavity with one end of the magnet provided with a magnetic circuit sheet 6 and the other end of the magnet opposed to a magnetic circuit sheet 5 disposed on the undersurface of the magnetic filter cavity, thus to form a closed magnetic circuit.
  • a fixed fuel passing gap is formed between the permanent magnet 2 and the magnetic circuit sheet 5.
  • the gap is of a width (measured in a direction perpendicular to the axis of the longitudinal through cavity) of about 1 ⁇ 5 mm, and preferably, 2 ⁇ 3 mm.
  • the magnetic circuit sheet 5 is mounted in a recess of the housing on the wall surface of the magnetic filter cavity which may be realized though a shrink fit and a compression bonding of an industrial gelatin.
  • the wall surface is in use the bottom surface of the magnetic filter cavity.
  • the permanent magnets 2, 3 and 4 are made as cylindrical bodies from a material of NF30 with diameters and heights all in the range from 6 mm to 80 mm.
  • the inherent coercive force of each permanent magnet is in the range of 18 000 000 ⁇ 20 000 000 ampere per meter (18 000-20 000 oersteds).
  • the magnetic field intensity of the N-pole face is in the range from 0,40 to 0,52 tesla (4 000 to 5 200 gausses).
  • magnetic circuit sheets 5, 6, 7 and 8 are in shapes of circular disks or cylinders with diameters from 6 to 80 mm and thicknesses or heights from 0.3 to 10 mm, and all can be made from magnet conductance material such as iron DT4 of the industrial purity level or silicon steel sheet.
  • the fuel passes through the fuel supply pipe into the double cavity magnetization fuel-economizer.
  • the area passed by the fuel flow changes abruptly, and the flow rate of fuel changes suddenly from slowness to fastness, thus the fuel flow form substially turbulences.
  • the molecular group structures of the fuel under the turbulent state are in collision and friction with each other and turn, from a relative stable state to a metastable state under the influence of molecular Brownian movement.
  • the area passed by fuel flow in this gap changes from small to big, and again suddenly becomes very small, and the fuel which has been in a high speed turbulent state is again influenced intensively by a high density magnetic force line in the closed magnetic circuit formed by permanent magnets 3 and 4 as well as magnetic circuit sheet 7 and 8.
  • the molecular groups of metastable state are further broken up massively, the viscosity and density of the fuel are reduced, the fuel particules become smaller and easier to be dispersed, the level of fuel atomization is enhanced and the condition for fuel to combine with oxygen has been improved remarkably, so that the fuel can be combusted more sufficiently ; therefore the output power of engine can be increased and the exhaust gas is cleaned up.
  • the magnetic circuit sheets 7 and 8 are first attached respectively on the other ends of the opposed poles of permanent magnets 3 and 4, then the permanent magnets 3 and 4 are disposed in the magnetization cavity, a round block 10 is fixed on the magnetization cavity and sealed through on adhesive to prevent from leakage.
  • the fuel passing gap between permanent magnets 3 and 4 should have a width in the range of 5 ⁇ 2.0 mm.
