Abstract

A system includes an exhaust aftertreatment system including a particulate filter and a controller. The controller is configured to: receive a particulate filter regeneration event trigger; receive information, the information comprising a temperature regarding the particulate filter; determine the temperature regarding the particulate filter is below a temperature threshold associated with a particulate filter regeneration event; and responsive to determining the temperature regarding the particulate filter is below the temperature threshold, command the engine to operate in a cylinder deactivation mode, whereby at least one cylinder of a plurality of cylinders of the engine is deactivated.
