An exhaust treatment system associated with a power source is disclosed. The exhaust treatment system may have a filter located to remove particulate matter from an exhaust flow of the power source. The exhaust treatment system may further have a heat source located to elevate the temperature of the exhaust flow. The exhaust treatment system may also have a first sensor and a second sensor. The exhaust treatment system may further have a controller in communication with the heat source, the first sensor, and the second sensor. The controller may be configured to receive a particulate matter load value and a power source load value and activate the heat source when the particulate matter load value is above a particulate matter load threshold value and the power source load value is below a power source load threshold value that is indicative of the exhaust flow being within an exhaust flow range.

Exhaust treatment system implementing regeneration control

In one aspect, the present disclosure is directed to a method for treating exhaust from an engine. The method may comprise generating a first signal indicative of an engine load and generating a second signal indicative of a pollutant level. The method may further comprise recirculating exhaust based on the first signal and injecting a reductant based on the first signal and the second signal.
