The fuel vaporizer system glow plug regenerates the diesel particulate filter by burning a controlled amount of fuel in the exhaust system upstream of the particulate filter. Fuel is delivered by the fuel vaporizer system pump and ignited by the fuel vaporizer system glow plug when the PCM commands a regeneration. The burning fuel increases the exhaust gas temperature to burn off particulates in the diesel particulate filter.
