Abstract
There is disclosed a method of regenerating at least one aftertreatment device in an exhaust system of an internal combustion engine by changing a calibration of the exhaust gas recirculation system with the engine to increase temperature of exhaust gas provided to the at least one aftertreatment device, and further incrementally changing the calibration to obtain an exhaust gas temperature within a target regeneration temperature range.
