Abstract:
1. A device for treating exhaust gas containing soot particles, the device comprising: at least one ionizer for ionizing soot particles; at least one separator having at least one surface separator for depositing ionized soot particles; said at least one separator including at least two at least partly electrically conductive neutralization regions for neutralization of ionized soot particles, said at least two neutralization regions being electrically insulated from one another; said at least two neutralization regions each having an electric potential, and said electric potential of at least one of said at least two neutralization regions being different than said electric potential of at least one other of said at least two neutralization regions, for achieving a targeted deposition of soot particles; and controllers each associated with a respective one of said at least two neutralization regions, said controllers having at least one electrical ground, at least one adjustable voltage source or at least one switch element.
