ABSTRACT:
A filter assembly for removing particulates from the exhaust gas of a diesel engine. The filter assembly includes a housing having an inlet pipe which may be coupled to the engine and an outlet pipe which may be open to the atmosphere, and a self-contained filtering mechanism disposed within the housing. An exhaust gas fluid path is defined from the inlet pipe through the self-contained filtering mechanism and out the outlet pipe. Each of the components of the self-contained filtering mechanism are highly resistant to high temperatures, so that the filtering mechanism may be electrically regenerated by heat, produced by a heater operatively associated with the filtering mechanism, which burns off accumulated, typically hydrocarbon, particulates.
