A system and method for regenerating particulate filters, catalyzed soot filters and NOx catalysts for a vehicle having a compression ignition engine. An engine control module controls engine operation and regeneration functions. The engine preferably includes an integrated starter/alternator/flywheel/retarder assembly. A load bank heater is provided in the exhaust system that is activated to directly heat exhaust gases raising the temperature thereof and approaching the temperatures required for regeneration and desulfation. Activation of the heater applies a load through the integrated starter/alternator/flywheel/retarder assembly that increases the load on the engine and in turn further increases the temperature of the exhaust to levels required for regeneration and desulfation.
