Abstract
A particle filter assembly adapted to be mounted in an exhaust gas stream of an internal combustion engine. The particle filter assembly includes a wire mesh filter or sinter metal filter having a mesh size sufficiently small to prevent the passage of carbonaceous particles above a predetermined size through the mesh. The filter is positioned in series with the exhaust gas stream from the engine. A source of electrical power is electrically connected to the filter to heat the filter to a temperature sufficient to oxidize the carbonaceous material in the filter to carbon dioxide.
