ABSTRACT OF THE DISCLOSURE The present invention provides a device for purifying the exhaust gases of diesel engines. This device has filter ele- ments for separating carbon black particles and these filter ele- ments are arranged in tandem in the cross section of a casing through which the exhaust gas flows. At least one filter element, which carries a catalyst lowering the ignition temperature of the carbon black and promoting its burn-off, repeatedly alternates with at least one filter element which carries a catalyst promot- ing the combustion of gaseous deleterious substances.
