Method and system for optimizing purge of exhaust gas constituent stored in an emission control device |
摘要 |
A method and system for optimizing the purging of a constituent gas of a vehicle engine's generated exhaust gas from an emission control device is disclosed wherein the amplitude of the output signal generated by a downstream switching oxygen sensor, and the time response of the sensor, is used to iteratively adjust a current purge time to obtain an optimized purge time. |
