ABSTRACT:
A diesel engine exhaust particulate filter-incinerator comprising an enclosed filter panel having particulate deposition surfaces bordered by electrodes of a high voltage power supply. Periodic incineration is accomplished by the collection on the surfaces of particulates in amounts sufficient to conduct sufficient electric current along paths through the particulates to heat them to incineration temperature. Ignition and burn off of particulates may be automatically accomplished by maintaining a suitable voltage across the electrodes at the edges of the collection surfaces to initiate arc-like current flow before the collected particulates reach a level that would plug the filter. Specific embodiments of exemplary filter constructions are disclosed.
