Abstract (en)
[origin: CA2063233A1] A particle filter for the exhaust gases of internal combustion engines is described, which can be regenerated by burning free, and in which the filter cartridges (12) include a support tube (16) with a lining of filter material (20). The support tubes 16 are conical. The lining with filter material (20) is preferably carried out such that the filter cartridge (12) has a cylindrical shape, i.e., the filter material (20) lining is thicker on the inlet side than on the outlet side However, lining with an equal thickness of filter material (20) over the entire length of the conical part of the filter cartridge (12) is also shown.
