DEVICE FOR REMOVING SOLID PARTICLES FROM EXHAUST GAS

摘要

A device for removing soot particles from exhaust gas of an internal combustion engine includes an electrical filter having a tubular housing and a central electrode in the form of a cylindrical shell coaxially arranged in the filter housing. The cylindrical shell is supported at its ends by insulators and is provided with a plurality of juxtaposed discharge points. The wall thickness of the cylindrical shell is about 0.05 mm and the discharge points are cut out in the wall of the cylindrical shell and being bent in radial direction toward the inner wall of the filter housing. The sides of the segments connecting the discharge points are oriented in the direction of the center axis of the electrode.
