    Abstract: A particulate converter for the collection and the incineration of particulate matters from diesel engine exhaust includes an exhaust path extending from the diesel engine through the particulate converter. The particulate converter further includes a housing and at least one candle located in the housing. An electrical incineration system may be electrically connected to a pulsed power supply for incinerating soot collected within the candle. A diesel oxidation catalyst (DOC) may be disposed in the exhaust path to generate sufficient amount of NO2 to assist in incineration. At least one exhaust cooling device may be provided for the control of exhaust temperature. A feedback control system may control exhaust gas temperatures based on pressure drop across the DPC, temperature ahead of the DPC and engine RPM.
