Abstract:
1. A method for converting soot particles of an exhaust gas, the method comprising the following steps: providing a device for treating the soot particles having: a) providing at least nitrogen dioxide or oxygen in the exhaust gas by using the at least one source of nitrogen dioxide or oxygen; b) ionizing soot particles with an electrical field created by the at least one ionization element; c) depositing electrically charged soot particles on inner channel walls of the channels of the at least one surface precipitator and preventing a predominant deposition of electrically charged soot particles in the inlet region by using the at least one deposition inhibitor; and d) placing at least nitrogen dioxide or oxygen in contact with the soot particles deposited on the inner channel walls of the at least one surface precipitator.
