INCREASE AFTERTREATMENT TEMPERATURE DURING LIGHT LOAD OPERATION

Systems, methods, and apparatuses are provided for increasing exhaust gas temperature. A system includes a valve and a controller coupled to the valve. The controller is structured to determine that an exhaust manifold pressure does not meet an exhaust manifold pressure setpoint and in response, cau...

Beschreibung
Zusammenfassung:	Systems, methods, and apparatuses are provided for increasing exhaust gas temperature. A system includes a valve and a controller coupled to the valve. The controller is structured to determine that an exhaust manifold pressure does not meet an exhaust manifold pressure setpoint and in response, cause an adjustment of an effective flow area of exhaust gas from an engine. The adjustment of the effective flow area is structured to increase an exhaust gas temperature.
