Abstract
A particulate filter regeneration system for an internal combustion engine includes a plurality of combustion cylinders, an intake manifold and an exhaust manifold. The particulate filter regeneration system includes a particulate filter adapted for communication with the exhaust manifold, a flame heater adapted for communication with the intake manifold, and a temperature indicator for providing an indication of a temperature associated with the exhaust manifold. A controller is coupled with the temperature indicator and the flame heater. The controller actuates the flame heater dependent upon a particulate filter regeneration indicator and a signal from the temperature indicator indicating a temperature of less than approximately 300° C.
