Abstract
A device for treating exhaust gas containing soot particles, includes at least one ionization element for ionizing soot particles and at least one separation device having a surface precipitator for depositing ionized soot particles. The at least one surface precipitator includes at least two at least partially electrically conductive neutralization regions that are electrically insulated from each other in order to neutralize ionized soot particles. A method for converting soot particles of an exhaust gas includes applying different electric potentials. A motor vehicle includes the device and carries out the method.
