Abstract: A system includes a controller coupled to an exhaust gas aftertreatment system coupled to a plurality of combustion cylinders of an engine. The controller is structured to: determine that the engine is operating in a low load operating condition; deactivate a combustion cylinder based on the determination that the engine is operating in the low load operating condition such that an exhaust gas temperature threshold corresponds with when the combustion cylinder is deactivated; increase an engine exhaust gas temperature while the combustion cylinder is deactivated via at least one thermal management command; and reactivate the deactivated combustion cylinder in response to the engine operating with a load greater than a preset threshold for a certain period of time.

Abstract: An engine control system and method of controlling an engine system are provided. The engine control system includes at least one sensor module configured to generate an exhaust condition signal based on a determined condition in an exhaust component and a cylinder bank control module communicatively coupled to the at least one sensor module. The cylinder bank control module is configured to cause transmission of a first bank control signal to cause a first bank of cylinders of an engine to deactivate at least in part in response to a determination based on the exhaust condition signal that a hydrocarbon mass quantity is above a pre-determined hydrocarbon mass quantity threshold.

Abstract: An apparatus includes an engine load module structured to detect an engine operating state of the engine and generate an engine status report; a timing module structured to receive the engine status report and generate a cylinder request after the engine has been in a certain engine operating state for a certain period of time; and a cylinder module structured to receive the cylinder request and generate a cylinder command to be sent to the engine to deactivate a portion of combustion cylinders based on the engine operating state existing for the certain period of time.
