Device for filtering soot particles from internal combustion engine exhaust gas containing adhered particles comprises outer container of machine, and filtering device made of porous material

摘要

A device for filtering a fluid containing adhered particles comprises an outer container (3) of a machine, and a filtering device (2) made of porous material. The porous material (6) has several folds running in the flow direction and has a cross-section with a closed geometric shape with an inner opening (4). Preferred Features: The porous material has open toothed partial regions (7) separated from each other by a fold. The outer container forms a sound damper in the exhaust gas system with a filter unit. The porous material is made of a sintered material consisting predominantly of a metallic material.
