摘要：
An apparatus for cleaning the exhaust gases of diesel engines, and especially for removal of soot particulates, utilizing series connected filter elements installed in the cross section of a housing traversed by the exhaust gas, wherein at least one filter element carrying a catalyst that lowers the ignition temperature of the soot and assists in soot burn off alternates several times with at least one filter element carrying a catalyst that assists the combustion of gaseous pollutants.
