ABSTRACT:
A collection device for collecting, under electrical control, particles (10) in an exhaust from a diesel engine is disclosed. The device has a needle electrode (8) having a needle tip (8a) for charging up the particles (10) by creating a corona discharge around the needle tip (8a) collecting electrode (11) for collecting the charged particles (10a) by electrostatic force and a high voltage power source (13) for applying prescribed high voltage between the needle electrode (8) and the collecting electrode (11), the high voltage power source (13) electrically being connected with the needle electrode (8) and the collecting electrode (11).
