Abstract
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.
