Abstract
Methods, apparatuses, and systems for managing a multiple, and particularly a dual-selective catalyst reduction (SCR), exhaust aftertreatment system according to one or more determined reductant dosing strategies are disclosed. A method includes: receiving, by a controller, data indicative of a catalyst of an aftertreatment system; determining, by the controller, a reductant dosing strategy based on a comparison of the data indicative of the catalyst to a respective threshold; and commanding, by the controller, an amount of reductant dosing based on the determined reductant dosing strategy.
