Abstract
A system includes an internal combustion engine producing exhaust gases as a byproduct of operation and an aftertreatment system that treats the exhaust gases. The system further includes a controller that is structured to functionally execute operations to enhance the temperature of the aftertreatment system. The controller includes an operating condition monitoring module that interprets a temperature value at a position upstream of a catalyst positioned in the aftertreatment system. The controller further includes an operating condition management module that interprets a threshold temperature value, and an engine management module that provides an engine operation command to continue engine operation in response to the temperature value being at least equal to the threshold temperature value.
