More Information
Summary:The present invention relates to a catalyst, comprising a carrier substrate of the length (L) which extends between two carrier substrate ends (a and b) and has two coating zones (A and B), wherein the coating zone (A) comprises a zeolite and palladium and, proceeding from the carrier substrate end (a), extends on a part of the length (L), the coating zone (B) comprises the same components as coating zone (A) and platinum and, proceeding from the carrier substrate end (b), extends on a part of the length (L), wherein L=LA+LB, wherein LA denotes the length of the coating zone (A) and LB denotes the length of the coating zone (B). The invention also relates to an exhaust system containing said catalyst.
