Abstract
A method and apparatus for disposing of particulate matter retained in an exhaust gas filter of an internal combustion engine, using an electric current source. For the purpose of good auxiliary energy utilization and minimization of equipment complexity, ignition and combustion of the particulates are initiated by the flow of current through the particulate matter itself (the particulates themselves serving as an electrical heating conductor). A suitable electrode configuration is provided to supply the ignition energy to the filter element. The electric input for the combustion of the particulates is applied via an impressed power supply.
