Abstract
A soot filter arrangement for an exhaust gas flow of an internal combustion engine, especially an air-compressing internal combustion engine. The filter arrangement includes a housing with feed and discharge connections for the exhaust gas stream in a mineral filter material arranged in the housing. The material is provided on a support pipe equipped with passage openings which enable the exhaust gas stream to enter the support pipe in a radial direction and leave the same in an axial direction. Several support pipes are provided at a mutual spacing in a parallel relationship and the filter material includes a thread of spun silicon dioxide fibers wound onto the support pipes.
