A method for controlling an internal combustion engine with a catalytic converter for exhaust-gas aftertreatment, comprising specification of a target fill level profile is proposed, which fluctuates between an upper threshold value and a lower threshold value, of at least one exhaust-gas component that can be stored in the catalytic converter, determination of a present fill level of the at least one exhaust-gas component in the catalytic converter on the basis of a theoretical catalytic converter model, and control of the internal combustion engine so as to generate an exhaust gas with a target concentration of the at least one exhaust-gas component such that a deviation between the present fill level and the present target fill level in accordance with the target fill level profile is reduced.

A system for removing dust from exhaust gas, comprising a dust removing system inlet, a dust removing system outlet, and an electric field apparatus (1021). The electric field apparatus (1021) comprises an electric field apparatus inlet, an electric field apparatus outlet, a dust-removing electric field cathode (10212) and a dust-removing electric field anode (10211).
