摘要: The invention relates to a method for operating a motor vehicle exhaust-gas aftertreatment system (1), in which oxygen is fed to and removed from the oxygen tank (8) of an exhaust-gas aftertreatment component (7). According to the invention, the oxygen quantity in the oxygen tank (8) is determined and a rich-lean cycle is influenced in accordance with the determined oxygen quantity. The invention also relates to a motor vehicle exhaust-gas aftertreatment system (1), which permits a temperature regulation of the oxygen tank (8) and/or an uninterrupted desulphation during the transition between a rich operation and a lean operation.
