Abstract
A system, method, and software for determining an amount of reductant to be supplied to a NOx adsorber during a regeneration event is disclosed. A reductant calculation module is executable by an electronic control unit for calculating a quantity of reductant delivered which is required to periodically regenerate the adsorber by accumulating the reductant fuel delivered as a function of a total fuel quantity being supplied to the internal combustion engine by a fuel system and subtracting an amount of fuel required to achieve a stoichiometric air to fuel ratio at an inlet of the adsorber.
