Title: Particulate filter abnormality determination method and abnormality determination device
Inventor: YOSHIDA HIROSHI
IPC: B01D46/42
Filed: 2019-04-23
Abstract: To prevent such a situation that a particulate filter is erroneously determined as abnormal during a lean operation.SOLUTION: A differential pressure on upstream and downstream sides of GPF (particulate filter) 33 is detected by a pressure sensor 35. When a predetermined condition is satisfied, by comparing an average value of the detected differential pressure with a determination threshold, existence of abnormality (thermal damage) of the particulate filter is determined. During a lean operation, abnormality determination is prohibited. For each detected differential pressure, it is preferable that a weight value is determined from a predetermined weight characteristic, and a timing at which an integrated value of the weight value is not less than a predetermined value is made to be the timing when the predetermined condition is satisfied. In this case, by resetting the integrated value of the weight value during the lean operation, abnormality determination in the lean operation can be prohibited. It is preferable that an average value compared with a determination threshold is made to be an average travelling value of a weight differential pressure weighed by the weight value.SELECTED DRAWING: Figure 12
