Abstract
A method for regenerating a particulate filter in an exhaust system of an internal combustion engine, wherein it is thereby provided that the quantity of overrun air in the overrun operation of the combustion engine be adapted to the air required for oxidizing the soot trapped in the particulate filter to achieve a rapid and efficient regeneration of the particulate filter, and it is provided that a throttle valve be opened in overrun operation to an extent that allows a maximum permissible soot conversion without risking thermal damage to the particulate filter.
