ABSTRACT:
A computer control system is described that monitors the functionality of an emission control device that is capable of storing NOx and oxygen during lean conditions, and releasing/reducing the stored oxygen and NOx during rich operating conditions. The computer uses a readable storage medium having stored data representing instructions executable by a computer. The instructions utilize a ratio between a lean operating time and a rich operating time to determine whether the catalyst has degraded.
