System for determining NOx conversion efficiency of an exhaust gas aftertreatment component |
摘要 |
A system for determining a NOx conversion efficiency of an exhaust gas aftertreatment component comprises means for determining an operating temperature of the exhaust gas aftertreatment component, and a control circuit. The control circuit includes a memory having instructions stored therein that are executable by the control circuit to determine a time duration that the operating temperature of the exhaust gas aftertreatment component is above a predefined temperature, and to determine the NOx conversion efficiency of the exhaust gas aftertreatment component as a function of the time duration. |
