Abstract
Systems and methods for aftertreatment system thermal management using cylinder deactivation and/or intake-air throttling are disclosed. Systems and methods for thermal management of an aftertreatment system are provided herein. A controller coupled to an engine and an exhaust aftertreatment system is configured to: receive a first temperature value associated with the exhaust aftertreatment system and a second temperature value associated with the engine; determine, based on comparing the first temperature value to a first threshold, a thermal management mode including a first thermal management mode or a second thermal management mode; determine, responsive to determining the thermal management mode and based on comparing the second temperature value to a second threshold, an operating mode for the thermal management mode including at least one of a first operating mode or a second operating mode; and initiate the at least one of the first or the second operating mode.
