| abstract | (57) [Abstract] [Purpose] While the catalyst deterioration starts, accurate emission control is executed to maximize the performance of the catalyst, while the deterioration condition that is difficult to leave the catalyst is accurately judged. Then, a predetermined process such as an alarm is executed. [Configuration] In a double O 2 sensor system, a second O 2 sensor smoothed value V is used for correction of feedback control. 3 is used, and the second O 2 is used in the catalyst deterioration determination. The raw output voltage V2 of the sensor is used. [Effect] By using the smoothed value V3, the feedback control can be executed without being biased to the overrich side or the over lean side, and the purification capacity can be maximized even after the start of catalyst deterioration. By determining the state of catalyst deterioration, it is possible to make accurate deterioration determination. |
