Abstract
A method of operating a fuel reformer to regenerate a NO.sub.X trap includes operating the fuel reformer to produce a reformate gas comprising hydrogen and carbon monoxide and advancing reformate gas through the NO.sub.X trap so as to regenerate the NO.sub.X trap. The method further includes determining if a SO.sub.X regeneration of the NO.sub.X trap is to be performed and generating a SO.sub.X -regeneration control signal in response thereto. The temperature of the NO.sub.X trap is raised and reformate gas is advanced into the NO.sub.X trap in response to the SO.sub.X -regeneration signal so as to remove SO.sub.X from within the NO.sub.X trap. A fuel reformer system is also disclosed.
