摘要
A method and system are disclosed for controlling a lean burn engine coupled to an emission control device that stores oxidants during lean operation, and reacts the stored oxidants during stoichiometric or rich operation, the method comprising estimating amounts of NOx stored in the device along a plurality of axial positions of the device and adjusting an operating parameter based on said estimate.
