  • Particulate trap regeneration temperature control system
    Patent number: 7677028
    Abstract: In one aspect, the present disclosure is directed to a particulate trap regeneration temperature control system. The system may include a particulate trap configured to remove one or more types of particulate matter from an exhaust flow of an engine. The system may also include a heating system configured to increase the temperature of the particulate trap. The system may further include a controller configured to control operation of the heating system during execution of a thermal regeneration event of the particulate trap. The controller may control operation of the heating system by effectuating a first temperature increase of the particulate trap at a predetermined rate up to a first predetermined temperature. The controller may also be configured to effectuate a first temperature hold by maintaining the temperature of the particulate trap at the first predetermined temperature for a predetermined amount of time.
