  • Filtering structure, especially particle filter for exhaust gases of an internal combustion engine, and associated exhaust line
    Patent number: 7547343
    Abstract: This structure comprises first and second filtering elements (15A, 15B) which are respectively provided with a first and a second face (24A, 24B) arranged opposite each other and a seal (17) connecting said faces (24A, 24B). The first face (24A) comprises at least a first region (35A) that does not adhere, or only slightly adheres to said seal (17), opposite a first region (33B) that strongly adheres to said seal (17) of the second face (24B). The first region (35A) that does not adhere or only slightly adheres is delimited by at least a portion of the edge (37) common to the first face (24A) and a discharge face (23). The first region (35A) that does not adhere or only slightly adheres comprises a side (41A) that diverges towards the discharge face (23) and which extends up to said common edge (37).

  • Structure for filtering an internal engine exhaust gases and associated exhaust line
    Patent number: 7503170
    Abstract: The invention concerns a structure (11) comprising a filtering member (21) comprising intake conduits (35) for the gases to be filtered, and conduits (37) for extracting the filtered gases, separated from the intake conduits (35) by porous filtering walls (43). The intake conduits (35) emerge into openings (49) for discharging respective residues, provided downstream of the respective intake openings (47). The openings discharging residues (49) of the intake conduits (35) open into a common manifold (25) for receiving solid filtering residues, forming counter-pressure means for the intake conduits (35). Said manifold (25) is isolated from the extracting conduits (37). The invention is applicable to particulate filters for exhaust gases of a motor vehicle diesel engine.
