Document Type and Number:
WIPO Patent Application WO/2020/054815
Kind Code:
A1
Abstract:
The purpose of the present invention is to sufficiently remove PM deposited in a particulate capturing filter. An exhaust purification device (100) is provided with a particulate capturing filter (6) which captures particulate matter in exhaust gas discharged from an internal combustion engine (1), and a control unit (10) which, on the basis of a value related to the operation time of the internal combustion engine (1), determines the start of a regeneration process for removing particulate matter deposited in the particulate capturing filter (6), and which, on the basis of the time for which the regeneration process has been performed, determines the end of the regeneration process.
