摘要 |
An apparatus for determining a deterioration of a NOx sensor response rate in an internal combustion engine system includes an engine control module configured to stop fueling to an internal combustion engine during motoring of the internal combustion engine. The apparatus also includes a signal monitoring module configured to monitor a NOx sensor signal after the engine control module stops fueling to the internal combustion engine during motoring of the engine and store NOx sensor signal data corresponding to the monitored NOx sensor signal. Additionally, the apparatus includes a time constant module that is configured to determine a time constant of the NOx sensor response after the engine control module stops fueling. The apparatus further includes a response rate deterioration module configured to determine a response rate deterioration value of the NOx sensor based at least partially on the determined time constant. |
