Reductant injection control strategy
A base dose module generates a base dose signal that corresponds to a mass flow rate of a dosing agent. A 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...

| Zusammenfassung: | A base dose module generates a base dose signal that corresponds to a mass flow rate of a dosing agent. A 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. |
