Abstract
Device for reduction of exhaust gas particulates in an exhaust pipe, comprising in combination a two-pole high-voltage generator, and a plurality of conductors alternately connected to one or the other of the poles. The conductors constitute substantially the only obstruction to flow of exhaust gas through the pipe and occupy a total area which is less than 50% and more than 10% of the pipe cross section. Air is introduced into the pipe upstream of the conductors, and a probe analyzes the downstream gas and regulates the air introduction according to the detected composition.
