THERMAL MANAGEMENT OF EXHAUST GAS VIA CYLINDER DEACTIVATION
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 determi...

| description | 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. |
