摘要： A method of regulating an amount of NH3 stored in a catalyst of an exhaust after-treatment system includes determining a mass of NH3 into the catalyst based on a dosing rate of a dosing agent that is injected into an exhaust stream upstream of the catalyst and determining a mass of NH3 out of the catalyst. An accumulated mass of NH3 within the catalyst is calculated based on the mass of NH3 into the catalyst and the mass of NH3 out of the catalyst. The dosing rate is regulated based on the accumulated mass of NH3 within the catalyst.

摘要： A dosing module for a vehicle comprises a base dose module, a dose adjustment module, and a dose determination module. The base dose module generates a base dose signal that corresponds to a mass flow rate of a dosing agent. The dose adjustment module receives an ammonia (NH3) signal and determines a first dose adjustment based upon the NH3 signal. The NH3 signal indicates NH3 measured downstream of a catalyst. The dose determination module generates a dosing signal based upon the base dose signal and the first dose adjustment.
