ABSTRACT:
A system for detecting deterioration of a catalyst monitors temperature of catalyst. The system sets a temperature criterion which represents possible lowest temperature when the catalyst is in a normal condition. Abnormality of the catalyst is detected by detecting the catalyst temperature lower than the temperature criterion.
