FILTER ELEMENT FOR FILTERING EXHAUST GASES OF AN INTERNAL COMBUSTION ENGINE

摘要

The invention relates to a filter element for filtering the exhaust gases of an internal combustion engine. It comprises inlet ducts (28) that are open on the inlet side and closed on the outlet side in the direction of flow and outlet ducts (30) that are closed on the inlet side and open on the outlet side in the direction of flow. The inlet ducts (28) and the outlet ducts (30) are delimited by joint porous filter walls (32). The invention is characterized in that the inlet ducts (28) comprise, in their cross-section, a surface having at least one first concave section (36) and at least one second concave section (38), a second inlet duct section (42) delimited by the second concave section (38) being narrower in sum than a first inlet duct section (44) delimited by the first concave section (36).
