Abstract: A method is provided for operating a regeneration assembly to regenerate a filter assembly during a regeneration cycle, and for supplying fuel through a fuel flow path to at least one fuel injector unit associated with the regeneration assembly during the regeneration cycle. The method includes dispensing a cleaning substance into the fuel flow path during a cleaning cycle. The method further includes directing the cleaning substance through the at least one fuel injector unit during the cleaning cycle.

Abstract: A control system for a power system is disclosed. The control system has a first valve mechanism, a second valve mechanism, and a controller in communication with the first and second valve mechanisms. The controller is configured to direct a single electronic control signal to the first and second valve mechanisms. Actuation of the first valve mechanism is initiated in response to the value of the single electronic control signal exceeding a first threshold value, and actuation of the second valve mechanism is initiated in response to the value of the single electronic control signal exceeding a second threshold value.

Abstract: An exhaust treatment system for a power source is disclosed. The exhaust treatment system has an inlet configured to receive an exhaust flow from the power source, a filtering medium configured to remove particulate matter from the exhaust flow, and an outlet configured to direct the exhaust flow from the filtering medium to the atmosphere. The exhaust treatment system also has a heating device configured to raise the temperature of the particulate matter entrained within the filtering medium, a supply of pressurized air, and a pilot-operated valve configured to selectively direct the pressurized air to the heated particulate matter.
