Abstract
A control system is provided for thermal management of an aftertreatment device in an engine that is provided in an enclosure. The engine has a cooling fan that is operable in a first direction to cool said engine. The fan is also operable in a reverse direction opposite to the first direction. The control system includes a first temperature sensor that measures a temperature of the engine or the enclosure. The control system further includes a second temperature sensor that measures a temperature of the aftertreatment device. The control system also includes a processor that is coupled to the first and second temperature sensors. The processor is configured to issue control signals, based on whether regeneration is required by the aftertreatment device or not, for selectively controlling a direction of operation associated with the cooling fan.
