Determination method of exhaust gas processing apparatus and determination system of exhaust gas processing apparatus

摘要

The determination method of the DPF includes heat damage information that is mounted on the first working machine 1 and indicates the thermal damage degree of the DPF 20 including the DOC 22 and the CSF 23. An acquisition step of acquiring the accumulated thermal damage information by acquiring based on the identification code and accumulating the thermal damage information, and a determination step of determining whether to use the DPF 20 based on the accumulated thermal damage information.
