Catalyst for cleaning exhaust gases of an internal combustion engine

摘要

Catalyst arrangement for purifying the exhaust gas from an internal combustion engine comprises an inlet region (16) for the exhaust gas in the flow channel (18) made of a material that has low adhesion for liquid or solid combustion residues. Preferred Features: The non-adhering material in the inlet region is applied as a layer onto a carrier body (24) of the catalyst. The material is made of high-temperature resistant plastic, polished ceramic, enamel, glaze, glass-ceramic or glass. The carrier is made of a foamed ceramic.
