Abstract
A self-cleaning particle filter for Diesel engines is provided. The filter includes a filter housing, control circuitry, a removable filter cartridge and independent power source. The removable filter cartridge includes a number of sintered metal strips sewn to a sheet of inorganic material to provide a filter sandwich. Current is delivered to the metal filter strips to efficiently burn off carbon, lube oil and unburned fuel particulates which have been filtered from exhaust gas.
