Abstract: The invention relates to a coating dispersion for producing catalyst-promoting coats on an inert, structure-reinforcing body. The solids of the dispersion are present in various grain size fractions and lead to a rougher coating surface having improved exchange between exhaust gas and catalyst surface and improved heating-up behaviour resulting therefrom.

Abstract: The invention relates to an arrangement for catalytic purification of the exhaust gases of internal combustion engines, especially two-stroke engines, consisting of a jacket tube (1) which is arranged in the exhaust path and in which there is installed a perforated inner tube (3) to form a narrow annular space (5) between the jacket tube and the inner tube. The inner tube (3) is occupied by a catalyst.

Abstract: The present invention provides a device for purifying the exhaust gases of diesel engines. This device has filter elements for separating carbon black particles and these filter elements 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 promoting the combustion of gaseous deleterious substances.
