Abstract
A method of regenerating at least one diesel particle filter, in which exhaust gas is introduced through a supply line into the at least one diesel particle filter and is discharged from it through a discharge line, while heating of the exhaust gas flowing through the at least one diesel particle filter takes place, a closed circulating air circuit being created through which exhaust gas emerging from the at least one diesel particle filter may be introduced back into the latter.
