Abstract
A method for predicting oxygen capacity of an LNT during storage phase of such LNT and the amount of NOx stored in the LNT during purge phase thereof as a function of the time history of an output signal produced by an exhaust gas sensor disposed downstream of the LNT. Oxygen storage capacity of the (LNT) is estimated by integrating output signal over time to determine the amount of oxygen stored in the LNT as function of time.
