  • Filter Regeneration Using Plasma
    Publication number: 20080127993
    Abstract: An emission control device, such as a filter, is regenerated by exposure to plasma. Plasma breaks down carbon-based residues, such as soot, to enable the filter to be easily cleaned and regenerated without subjecting the filter to heat-related stress associated with thermal regeneration methods. Secondary plasma generation is used to overcome impediments caused by the presence of a metallic housing and/or metal-containing materials such as a washcoat or mesh in the filter.
