  • Exhaust treatment system implementing regeneration control
    Patent number: 8322132
    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.
    Type: Grant

  • System for controlling exhaust aftertreatment
    Patent number: 7886528
    Abstract: 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.
