Abstract:
This method for restoring a diesel particle filter is provided with: a first step for supplying to a diesel particle filter a first gas wherein an inert gas and a first combustion exhaust gas obtained by combusting fuel in a burner are mixed, igniting the soot deposited at the diesel particle filter; and a second step for, after the first step, supplying to the diesel particle filter a second gas having a lower flow rate and a higher oxygen concentration than the first gas to the diesel particle filter, further combusting the ignited soot.
