Patent number: 8444734Abstract: 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.Type: GrantFiled: February 15, 2007Date of Patent: May 21, 2013Assignee: Alantum CorporationInventors: Shadi Saberi, Alexander Böhm, Dirk Naumann, Lloyd Timberg

Patent number: 8444738Abstract: 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.Type: GrantFiled: July 18, 2008Date of Patent: May 21, 2013Assignee: Alantum CorporationInventor: Hyun Tae Kim
