Abstract

A soot filter in the exhaust gas flow of air-compressing internal combustion engines, with a preferably cylindrically shaped filter housing arranged in proximity of the exhaust of the internal combustion engine, to which are connected radial or tangential inlet connections and in which is arranged ceramic fiber material; the fiber material forms hollow spaces together with the inner wall surfaces of the filter housing, which hollow spaces receive the exhaust gases after flowing through the filter parts and which conduct the exhaust gases in the axial direction of the filter housing to the exhaust line axially connected thereto.
