Abstract

A process for continuous regeneration of an exhaust-gas filter of an internal combustion engine having a supercharger unit is described. Operating parameters of the engine are compared to pre-set values in a control device to adjust the position of a throttle flap valve preceding the supercharger unit in order to maintain a high temperature on the exhaust-gas filter.
