Abstract

Method for filtering combustible particles from an exhaust gas stream, and for periodically rejuvenating the filter bed by incinerating retained particles. At least a portion of an engine's exhaust gas stream is initially preheated to raise the filter's catalytic segment to a pre- determined "lightoff" temperature. A supplementary fuel flow e.g. of H2, propane, diesel fuel, kerosene, or alcohol is then introduced to the catalyst segment which, being at "lightoff" temperature, will cause the supplementary fuel to react. Subsequent to the initiation of this oxidation reaction, further energy input to increase the exhaust gas to "lightoff" temperature, can be reduced or cut-off without effecting the continuing particle incineration rate.
