Wabenstruktur und Abgasverarbeitungsvorrichtung

摘要

A honeycomb structure includes a pillar honeycomb unit having plural cells that extend from a first end face to a second end face of the honeycomb structure. The cells are partitioned by cell walls formed in a longitudinal direction of the honeycomb structure. The cell walls include a NOx adsorbing material and an inorganic binder and support an ammonia adsorbing material. The amount of the ammonia adsorbing material supported on the cell walls varies between the first end portion and the second end portion.
