  • Method and system for operating an internal combustion engine with multiple torque curves
    Patent number: 9429082
    Abstract: A method of operating an internal combustion engine includes the steps of: determining an upper torque curve at which exhaust emissions from the internal combustion engine are acceptable; determining a lower torque curve at which exhaust emissions from the internal combustion engine are acceptable; and operating the internal combustion engine using a command torque curve ranging between the lower torque curve as a lower limit and the upper torque curve as an upper limit.
    Type: Grant

    Date of Patent: August 30, 2016
    Assignee: Deere & Company
    Inventors: Brian Eugene Holthaus, Dick J. Goering
  • Internal combustion engine with power boost in response to impending load
    Patent number: 7805937
    Abstract: An internal combustion engine is associated with a remote load indicator which provides an output signal, corresponding to an impending increase in mechanical load. The internal combustion engine includes an air supply system and an electrical processing circuit. The electrical processing circuit is coupled with the load indicator and receives the output signal. The electrical processing circuit controls the air supply system to initiate an increase in an air supply to the internal combustion engine prior to the increase in mechanical load.
