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.
Claims1
In a device for reduction of exhaust gas particulates in an exhaust pipe, comprising in combination a two-pole high-voltage generator, a plurality of conductors alternately connected to one or the other of said poles, said conductors constituting substantially the only obstruction to flow of exhaust gas through said pipe and occupying a total area which is less than 50% and more than 10% of the internal cross section of the pipe, said connectors each consisting of a conductive metal grid arranged inside said pipe perpendicular to the general direction of flow of said exhaust gases, and means for introducing air into said pipe upstream of said conductors;
- the improvement wherein each said conductive metal grid is of spiderweb configuration consisting of a plurality of radially extending wires supporting and spacing apart a plurality of concentric circular wires.
