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 forincinerating 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 theDPC and engine RPM.

Description

[0001] Cross References to Related Applications [0002] This application claims U.S. Provisional Application No. 60 / 940,123, filed May 25, 2007, U.S. Provisional Application No. 61 / 015,875, filed December 21, 2007, and U.S. Provisional Application No. 61 / 015,883 entitlement. The content of the above application is incorporated herein by reference. technical field [0003] The present invention relates generally to aftertreatment devices for diesel and natural gas engines. More specifically, the present invention relates to the agglomeration, retention and incineration of particulate matter in composite wire mesh filter cartridges. More specifically, the present invention also relates to incineration by a reliable and controlled process. Background technique [0004] Particulate traps for diesel engine exhaust have been widely accepted and used for particulate emissions to comply with various government regulations for on-road diesel engines. Equipping diesel engines wit...
