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