    摘要： A dosing control system for a vehicle includes an adaption triggering module, a dosing management module, and an adaption ending module. The adaptation triggering module triggers performance of an adaptation event when a first amount of nitrogen oxides (NOx) measured by a first NOx sensor located downstream of a selective catalytic reduction (SCR) catalyst is greater than a predicted value of the first amount of NOx. The dosing management module disables dosing agent injection during the adaptation event. The adaptation ending module selectively delays ending the adaptation event after a predetermined number of phases of the adaption event have been completed based on a comparison of the first amount of NOx with a second amount of NOx measured by a second NOx sensor located upstream of the SCR catalyst.

    摘要： An engine control system includes a dosing control module and an offset determination module. The dosing control module actuates an injector to inject a first amount of reducing agent into exhaust gas produced by an engine during a period when a temperature of the exhaust gas is greater than a predetermined temperature threshold. The offset determination module determines an efficiency of a selective catalytic reduction (SCR) material based on measured amounts of nitrogen oxide (NOx) during the period and expected NOx amounts, wherein the measured amounts of NOx are measured at locations upstream and downstream from the SCR material, and wherein the expected NOx amounts are based on the temperature of the exhaust gas and the first amount of reducing agent.
