  • Method and control system for a valve
    Patent number: 9188035
    Abstract: A method of controlling a valve and a control system in a machine having an internal combustion engine, the system including the valve and an associated motor, and a temperature sensor that supplies a temperature signal to a controller in electrical communication with the motor. The controller supplies a closing current to the motor at a temperature signal corresponding to a temperature no greater than a preset temperature parameter, the closing current being at or above a nominal operating current of the motor and being furnished for a preset period of time.
    Type: Grant

  • Air supply system for a regeneration assembly
    Patent number: 8234857
    Abstract: A method of initiating regeneration of a filter assembly is disclosed. The method includes determining when regeneration of a filter assembly is to be initiated. The method also includes opening a first air valve configured to permit air flow to a regeneration assembly below a predetermined flow rate and at a sufficient flow rate to achieve ignition. The method further includes detecting ignition, and after ignition, opening a second air valve configured to supply air flow to the regeneration assembly above the predetermined flow rate and at a sufficient flow rate for regeneration.
