Abstract
A system is disclosed that may include a gas recirculation passageway configured to recirculate gas exiting an engine to an intake of the engine prior to the gas reaching an aftertreatment system associated with the engine. The system may include a valve configured to control a gas recirculation of the gas recirculation passageway. The system may include a controller configured to cause, during a compression braking procedure for the engine, actuation of the valve to produce the gas recirculation when the aftertreatment system is performing an operation that is temperature-dependent.
