Definitions

  • the present invention relates to exhaust emission purifying devices in a field of exhaust emission purification of internal combustion engines of such as automobiles, ships and airplanes, in particular exhaust emission purifying devices in which a catalyst material is interposed in a path of a fuel pipe from a fuel tank to an internal combustion engine to reduce harmful matters in the exhaust emission from the internal combustion engine.
  • Catalyst materials described in JP-A-11-153319 are constituted of any one of nylon, silk and trimidite that can be easily positively charged.
  • catalyst materials described in Japanese Patent No. 2918880 are constituted by pressure-molding compositions made of a resin, a carbon source, a silicon dioxide source and glass fiber under heating followed by aging.
  • the present invention intends to improve a catalyst that is used in pre-combustion treatment of liquid fuel and thereby to provide an exhaust emission purifying device that can excellently reduce the harmful matters and improve the combustion efficiency and at the same time can realize the stabilization of product performance and cost reduction.
  • an exhaust emission purifying device in a path of a fuel pipe from a fuel tank to an internal combustion engine, a catalyst material that imparts negative charges to petroleum liquid fuel that goes through the fuel pipe is disposed, the catalyst material being made of a mixture of nylon and ceramics that generate minus ions.
  • a mixture of nylon and ceramics is used as a catalyst of petroleum liquid fuel.
  • the combustion efficiency of an internal combustion engine can be improved, the harmful matters (CO, HC, NOx) in the exhaust gas emitted from the internal combustion engine are reduced to contribute to environmental protection, harmful matter reduction effect several tens percent higher than that of the catalyst material made of nylon ball alone can be obtained, and more stable effect can be attained.
  • the inventive catalyst material is lighter in weight and has excellent moldability owing to the action of nylon; accordingly, the catalyst material can be arranged substantially uniformly in its magnitude and shape, resulting in stabilizing product performance. Still furthermore, in comparison with the catalyst material that is constituted by blending many raw materials, the producing cost can be suppressed lower.
  • a tube body in which a catalyst material is housed is inserted in a fuel pipe and liquid fuel past through the fuel pipe is brought into contact with the catalyst material.
  • the liquid fuel can be negatively charged and thereby the combustion efficiency of fuel can be improved, resulting in enabling to reduce the harmful matters emitted from the internal combustion engine, to contribute to environmental protection and to save the fuel.
  • the catalyst material is formed into balls having a diameter in the range of 5 to 10 mm by blending nylon and ceramics powders, a blending ratio of nylon and ceramics being in the range of (85: 15) to (95: 5) by weight ratio.
  • principal constituents of the ceramics that constitute the catalyst material include at least one kind of cerium, lanthanum, fluorine, neodymium and silicon dioxide.
  • the tube body is formed of nylon material that is likely to generate positive static electricity, and a place that is likely to be negatively charged such as a shroud next to a fan of a car body of the internal combustion engine and the tube body are connected so as to send negative charges to the tube body.
  • An exhaust emission purifying device cleans up an emission gas from an internal combustion engine of such as an automobile, ship or an aircraft, and as shown in Fig. 1 a catalyst material 10 that imparts negative electric charges to petroleum liquid fuel 12 past through a fuel pipe 18 is disposed in a path of the fuel pipe 18 from a fuel tank 16 to an internal combustion engine 14.
  • the catalyst material 10 is packed in a tube body 24 that is inserted in the fuel pipe 18.
  • the catalyst material 10 is made of a mixture of nylon and ceramics that generate minus ions, and when the liquid fuel 12 is brought into contact with the catalyst material 10 the minus ions are imparted to the liquid fuel 12 to negatively charge the liquid fuel 12 and thereby to negatively ionize. This is desirably performed immediately before the liquid fuel 12 enters the internal combustion engine 14.
  • the catalyst material 10 is preferably made in such a manner that nylon and ceramics made of powdery bodies of several ⁇ m to several hundreds ⁇ m are blended and formed into balls having a diameter of 5 to 10 mm, a blending ratio of nylon and ceramics being preferably in the range of (85: 15) to (95: 5) by weight ratio.
  • a blending ratio of nylon and ceramics being preferably in the range of (85: 15) to (95: 5) by weight ratio.
  • cerium Ce, lanthanum La, fluorine F, neodymium Nd and silicon dioxide SiO 2 that generate minus ions much are preferably contained, at least one kind thereof being able to be contained.
  • the catalyst material 10 is constituted of a mixture of nylon and ceramics. Accordingly, in comparison with the catalyst material that uses, for instance, ceramics alone, the catalyst material 10 becomes lighter in weight and excellent in the moldability by the action of nylon, resulting in simplifying to process into balls as mentioned above. As a result, the catalyst material 10 can be easily arranged into substantially uniform particle diameters and thereby the dispersion of performance of the respective products can be suppressed low. Furthermore, as shown in Fig. 3, to the catalyst material 10 that is processed in ball, a hole 30 and a groove 31 can be further formed easily; thereby, a surface area of the catalyst material 10 can be enlarged to increase a contact area with the liquid fuel 12, and thereby function as a catalyst can be further improved. Still furthermore, since the catalyst material 10 is constituted only of nylon and ceramics, in comparison with the catalyst material obtained by blending many raw materials, the producing cost can be suppressed low.
  • the liquid fuel 12 is brought into contact with the catalyst material 10 inserted in the fuel pipe 18 from the fuel tank 16 to the internal combustion engine 14, and thereby the liquid fuel 12 is negatively ionized.
  • air that becomes an air-fuel mixture being deprived of electric charges owing to friction with a car body, is positively ionized.
  • the negatively ionized fuel 12 and positively ionized air form an air-fuel mixture, since like electrostatic coating that makes use of static electricity, the respective electric charges attract each other, a homogeneous mixture can be obtained and thereby the combustion efficiency of the liquid fuel 12 can be heightened.
  • a tube body 24 is formed of nylon that is likely to be positively charged, in order to negatively charge the tube body 24 the tube body 24 is connected with a place that is likely to be negatively charged such as a shroud next to a fan 28 of a car body of an internal combustion engine, negative electric charges are continuously sent to the tube body 24 to negatively charge the liquid fuel 12, and thereby the combustion efficiency of the liquid fuel 12 is heightened.
  • the present invention is useful as a catalyst for various kinds of internal combustion engines that are mounted on automobiles, ships and the like and use petroleum fuel.
