Abstract: A method is disclosed for operating an internal combustion engine equipped with an aftertreatment device. The internal combustion engine is equipped with a cylinder having an exhaust gas port intercepted by an exhaust valve, the exhaust valve being actuated by means of a Variable Valve Actuation (VVA) system, An aftertreatment device regeneration is detected, and the exhaust valve closure is anticipated using the Variable Valve Actuation (VVA) system during the aftertreatment device regeneration to provide an exhaust valve actuation profile having an anticipated exhaust valve closure with respect to a baseline exhaust valve actuation profile.
