摘要： Deterioration of a catalyst provided in an exhaust system of the engine is determined. Air-fuel ratio sensors are provided in the upstream side and the downstream side of the catalyst. Air-fuel ratio is changed. Based on the sensor outputs in the upstream die and the downstream side of the catalyst, a parameter of a catalyst model representing a state of the catalyst is identified. The parameter is compared with a threshold to determine a state of the catalyst.

摘要： A system and method is provided for synchronizing a first and second signal of an exhaust sampling system. The first signal is generated by a first instrument and includes an exhaust flow rate component and a first instrument time stamp component. The second signal is generated by a second instrument and includes a pollutant concentration component and a second instrument time stamp component. The second instrument also generates a tertiary signal that has been influenced by the first signal and includes a second instrument time stamp component. A synchronization module determines a time relationship for synchronizing the first signal and the second signal by comparing the first flow rate component and the first instrument time stamp component of the first signal to the tertiary signal and the second instrument time stamp component of the tertiary signal. The synchronization provides accurate calculation of a pollutant mass flow rate.
