Abstract:
A method for regenerating a particulate filter in an exhaust system of an internal combustion engine. In a normal operation, the internal combustion engine is operated at a stoichiometric air/fuel ratio. To regenerate the particulate filter, it is provided that the air/fuel ratio be adjusted toward lean, and, at the same time, that the combustion in the combustion chambers of the internal combustion engine be stabilized by suitably adapting the ignition energy, the duration of ignition, and/or the ignition frequency, to prevent misfires and the associated uncontrolled entrainment of unburned fuel into the exhaust system. The inventive method for regenerating the particulate filter makes possible a more rapid and lower-emission regeneration of a particulate filter. Also, an internal combustion engine having an exhaust system and a control unit that is adapted for implementing a method according to the present invention.

Claim (Index 7):
The method as recited in  claim 1 , wherein an opening angle of a throttle valve ( 54 ) in an air supply system ( 50 ) of the internal combustion engine ( 10 ) is enlarged to regenerate the particulate filter ( 24 ) or the four-way catalytic converter ( 44 ).
