  • Patent number: 8444734
    Abstract: The invention relates to an apparatus for the separation of particles contained in exhaust gases of internal combustion engines in which the exhaust gas flow is guided through a filter medium in which particles can be absorbed and held back. The invention should improve the separation in a cost effective manner with respect to conventional particle filters. In accordance with the invention, the filter medium (1) is made from a metal open-pore foam having at least two layers (1.1, 1.2, 1.3) which each have a thickness, porosity and/or pore size in the flowthrough direction through the filter medium which differ from one another. In one embodiment, the particle filter includes first and second filter medium layers where the first filter medium has a mean pore size larger than a mean pore size of the second filter medium, and the first filter medium has a thickness that increases in a direction of the exhaust gas flow inlet passage of the filter housing.

  • Patent number: 8444738
    Abstract: Disclosed herein is a filter device for reducing automobile exhaust fume. The filter device includes a case, a front flange mounted inside the case, a rear flange mounted inside the case, and a filter member mounted between the front and rear flanged. The case includes an inlet port, a porous tube and an exhaust port. The filter member includes a laminated-type or rolled-up type metallic foam filter mounted between the front and rear flanges, and a jacket wrapped around the metallic foam filter. The exhaust gas that flows inside the porous tube passes through the metallic foam filter. The jacket is formed in a network form to maintain the shape of the metallic foam filter and provide durability thereto. The jacket is formed with a rectangular vent hole. The jacket holds the metallic foam filter such that the shape, construction and position of the metallic foam filter can be maintained.

  • Patent number: 8012598
    Abstract: The invention relates to metal foam bodies having an open-porous structure as well as a method for producing thereof wherein according to the set task such metal foam bodies are to be provided which achieve an increased oxidation resistance and/or an increased corrosion resistance. With the metal foam bodies having an open-porous structure according to the invention, for such metal foam bodies within the webs of the open-porous structure there are channel shaped cavities formed as being determined by the production. At the same time, the webs and cavities will be provided with a metallic protective layer made of a material differing from the metallic starting material of the foam body or the channel shaped cavities will be filled with this material. For this, an adequate metal powder or an alloy component being included in the powder will be used which becomes liquid and forms a liquid phase respectively during thermal treatment below a temperature at which the metal of the base foam body is melting.

  • Patent number: 7951246
    Abstract: The invention relates to open-pored metallic foam bodies as well as a method for manufacturing thereof. These metallic foam bodies are allowed to be advantageously used with ambient environmental conditions causing a high corrosion to many conventional materials, and accordingly reducing the lifetime thereof frequently. According to the set object, the metallic foam bodies should have a low mass simultaneously with a high specific surface, and increased corrosion resistance under chemically aggressive ambient environmental conditions. An open-pored metallic foam body according to the invention is then developed such that it is formed from a nickel-copper alloy having at least 40 percent by weight of nickel and yet a porosity of at least 90%.
