Patent ID: 6959542

Claim:
A method of operating an emission abatement assembly, the method comprising the steps of: determining if regeneration of a first DPNR device is to be performed and generating a first regenerate-DPNR signal in response thereto, operating a fuel reformer so as to produce and advance reformate gas to the first DPNR device in response to generation of the first regenerate-DPNR signal, determining if regeneration of a second DPNR device is to be performed and generating a second regenerate-DPNR signal in response thereto, operating the fuel reformer so as to produce and advance reformate gas to the second DPNR device in response to generation of the second regenerate-DPNR signal, positioning a diverter valve in a first valve position so as to direct reformate gas to the first DPNR device in response to generation of the first regenerate-DPNR signal, and positioning the diverter valve in a second valve position so as to direct reformate gas to the second DPNR device in response to generation of the second regenerate-DPNR signal.
