A flattened profile emission oxidizing device 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, a bypass through the enclosure for diverting flow from the main flow path, and a control means for selectively controlling the flow through the main flow path and the bypass in accordance with certain sensed conditons 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. A thermal stabilizer in the outlet of the device attenuates the peak temperatures of the exhaust gases.
A flattened profile diesel engine exhaust oxidizing device comprising an enclosure having an inlet for receiving diesel engine exhaust, a main flow path through said enclosure to an outlet of the enclosure, said main flow path containing a medium for trapping particulate material such as soot and removing significant amounts thereof from the exhaust flow through said main flow path, a by-pass through said enclosure for diverting flow from said main flow path, and a control means for selectively controlling the flow through said main flow path and said by-pass in accordance with certain sensed conditions relating to the status of engine operation, in which the medium is rectangular in shape and including a series of rectangular vanes along the length of the interior of the rectangular medium for taking axial flow and directing it perpendicularly through the medium.
A flattened profile diesel emission oxidizing device comprising an enclosure having a forward inlet for receiving diesel engine exhaust, a main flow path through said enclosure to a rearward outlet, a bypass through said enclosure between said inlet and said outlet for diverting flow from said main flow path, said flow path containing a medium for trapping particulate matter such as soot and removing significant amounts thereof from the exhaust flow through said main flow path and control means for selectively controlling the flow through said main flow path and said bypass 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 said main flow path, said main flow path comprising an electrostatic precipitator that is disposed in underlying relationship to said particulate trapping medium in said main flow path and a series of vanes that are disposed in underlying relationship to the electrostatic precipitator in said main flow path, said series of vanes serving to redirect exhaust flow passing axially through said main flow path perpendicularly, to distribute and pass the exhaust flow through the electrostatic precipitator and the trapping medium.
