ABSTRACT:
The present invention relates to a method for regenerating a filter that traps particulate matter contained in exhaust gas of an internal combustion engine. The regeneration method includes increasing an amount of soot having a low degree of graphitization in the filter. After the amount of soot having the low degree of graphitization is increased, a temperature of the filter is increased.
