摘要： A reformer system comprising a hydrocarbon reformer; a fuel supply system; an air supply system; a hydrogen sensor disposed in a reformate exhaust stream from the reformer; and a reformer controller for receiving input from the hydrogen sensor and setting the flow values for fuel and air to provide a desired O/C ratio in the reformate stream. A protocol of varying fueling rates is run in which a calibration relating hydrogen sensor values to O/C ratio is generated and is programmed into the controller. From this calibration, a fueling rate is selected which provides an O/C ratio within a predetermined range. The reformer system is especially useful for regeneration of a nitrogen oxides trap in a diesel exhaust system. The calibration protocol may be run during engine operation and can adjust the fueling rate when different diesel fuel mixtures are presented.
