ABSTRACT:
An oxidizing device with a microprocessor control means for removing soot and other particulates from the exhaust gases of a diesel engine having an enclosure with a forward inlet for receiving diesel engine exhaust, a main flow path through the enclosure having a medium for trapping soot and other particulates, a bypass through the enclosure for diverting flow from the main flow path, heating elements embedded in the trapping medium, and a microprocessor control means for selectively regenerating the trapping medium in accordance with certain sensed conditions relating to the status of engine operation and the condition of a particulate trapping medium that is disposed in the main flow path. The main flow path has an electrostatic precipitator that is disposed in underlying relationship to the particulate trapping medium in the main flow path and a series of vanes are disposed in underlying relationship to the electrostatic precipitator and serve to redirect the exhaust flow passing through the main flow path and distribute the exhaust flow over the electrostatic precipitator and the trapping medium.
