  • Control method for dual path NOx adsorber system
    Patent number: 7062905
    Abstract: A method of controlling a dual path NOx adsorber system. The amount of exhaust into the two paths of the system is controlled by a diverter valve at the beginning of each path. The valves are operated such that most of the time, the adsorbers are simultaneously in adsorption mode. The adsorbers alternate with each other to briefly enter a regeneration mode, during which they receive a very small amount of the exhaust flow and also receive supplemental fuel injection.
