ABSTRACT:
With a method of controlled regeneration of a diesel soot filter of a diesel engine the diesel soot filter is divided into a plurality of sections which are connected in parallel in the exhaust gas tract and into at least one of which the influx of exhaust gas is blocked in response to the exhaust gas temperatures measured downstream of the diesel soot filter. When the maximum admissible exhaust gas temperature downstream of the diesel soot filter is exceeded this section, consequently, is shut off in part or even completely from the exhaust gas stream so that the mass flow rate through the corresponding filter section is reduced or even cut off, while the mass flow rate through the remaining sections is increased in a way so as to again control the regeneration or even discontinue it.
