A method of regenerating in situ a DPM-contaminated diesel particulate filter assembly of an exhaust system connected to a diesel engine, said system comprising (a) a filter shell containing a filter element having an inlet face, an outlet face, and a DPM entrapping-body; (b) electrical heating means within said shell adjacent said inlet face connectable to an electrical power supply; (c) inlet temperature measuring means adjacent said inlet face and said heating means; (d) body temperature measuring means within said body; (e) means for receiving forced air within said shell and connectable to a forced air supply; (f) said heating means, said inlet and said body temperature measuring means and said forced air receiving means being connectable to a programmable logic controller (PLC); said method comprising the steps of (i) connecting said heating means, said temperature measuring means and said forced air receiving means to said PLC; (ii) connecting said heating means to said power supply; (iii) connecting said forced air receiving means to said air supply; (iv) heating said electrical heating means by said power supply to a desired temperature controlled by said PLC; (v) receiving said forced air from said air supply at a desired rate controlled by said PLC to effect heating of said air to a desired temperature by said heating means; (vi) passing the heated air through said inlet face and filter element to effect combustion of said DPM; and (vii) passing temperature data from said inlet and said body temperature measuring means to said PLC. 25 The method obviates the need to remove the DPF from a vehicle, particularly a heavy duty underground vehicle, during regeneration.
