Abstract
A dosing control unit (DCU) may receive operational information associated with a selective catalytic reduction (SCR) aftertreatment system. The DCU may generate a deposit prediction, associated with the SCR aftertreatment system, based on the operational information. The deposit prediction may include information that identifies a predicted size of a deposit in a dosing zone of a plurality of dosing zones associated with the SCR aftertreatment system. The deposit prediction may be generated using a deposit growth model associated with predicting sizes of deposits in the plurality of dosing zones. The DCU may select a dosing scheme, of a plurality of dosing schemes, based on the deposit prediction. The DCU may implement the selected dosing scheme in order to cause diesel exhaust fluid (DEF) to be dosed in the plurality of dosing zones in accordance with the selected dosing scheme.
