Abstract
Systems and methods for controlling a dosing of reductant for an internal combustion engine system including a catalyst are disclosed. The method includes measuring a value indicative of inlet temperature of the catalyst. When the inlet temperature is less than or equal to a first threshold, the method includes adjusting the dosing of reductant according to a first process. When the inlet temperature is greater than the first threshold, the method includes adjusting the dosing of reductant according to a second process, the second process being different than the first process.
