HC adsorbing material and device for judging deterioration of the HC adsorbing material

A HC adsorbing material whose deterioration can be judged with high accuracy and reliability. The HC adsorbing material contains a zeolite having cation adsorption sites (Al sites) to which are bonded ions of an element (Ce+) that exhibits oxygen storage capacity (OSC) in a nonionic state (when pres...

Zusammenfassung:	A HC adsorbing material whose deterioration can be judged with high accuracy and reliability. The HC adsorbing material contains a zeolite having cation adsorption sites (Al sites) to which are bonded ions of an element (Ce+) that exhibits oxygen storage capacity (OSC) in a nonionic state (when present as an oxide).
