Device for treating exhaust gas containing soot particles and motor vehicle having the device

Abstract

A device for treating exhaust gas containing soot particles includes at least one ionization element for ionizing soot particles, at least one filter element having at least one section to which an electric potential can be applied and at least one agglomeration unit for at least partial agglomeration of electrically charged soot particles. The agglomeration unit is disposed between the ionization element and the filter element and the agglomeration unit has at least one outer pipe and at least one inner element. The filtering power of an exhaust system of an internal combustion engine is therefore increased by an increase in the agglomeration rate of the soot particles. A motor vehicle having the device is also provided.
