Abstract
A working machine, an oxidation catalyst degradation detection device, an oxidation catalyst degradation detection method, and an oxidation catalyst degradation detection program are provided, which enable a suitable detection of a degradation of an oxidation catalyst. A working machine includes a temperature detecting device for detecting a temperature between an oxidation catalyst and a filter, and a controller. The controller calculates an average of temperatures detected by the temperature detecting device in a regeneration processing of the filter, and calculates a degradation degree of the oxidation catalyst on the basis of the calculated average.
