摘要：A computer control system is described that monitors the functionality of anemission 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 instructionsexecutable by a computer. The instructions utilize a ratio between a lean operating timeand a rich operating time to determine whether the catalyst has degraded.
