  • Feedforward engine control governing system
    Patent number: 6564774
    Abstract: In an engine control system (10) for an industrial internal combustion engine (12) driving a load (14) and desired to run at constant speed as controlled by an engine control unit (16) including a governor controlling an engine throttle (18), a governing system is provided for holding the engine (12) at relatively constant speed, notwithstanding load changes, by anticipating load change with pre-set loop modification control.
    Type: Grant

  • Turbocharger control management system throttle reserve control
    Patent number: 6161384
    Abstract: A controlled power system and method for an internal combustion engine having a turbocharger controls the engine to vary differential pressure across the throttle, delta P, throttle reserve, according to a predetermined throttle reserve profile relative to at least one engine parameter.

  • Electronically controlled wastegate valve for a turbo charger
    Patent number: 5816047
    Abstract: An electronically controlled wastegate valve is adjusted so that the pressure drop across a throttle in the engine approaches an adaptively generated, desired throttle pressure reserve value. The desired throttle pressure reserve value is based at least in part on a history of the engine load. In the preferred embodiment, the engine speed is used as a surrogate for engine load to determine the desired throttle pressure reserve value. The desired throttle pressure reserve value is preferably pushed downward over time by use of a constant negative gain term in the electronic controller. In this manner, the wastegate control provides sufficient throttle pressure reserve for satisfactory load acceptance when engine load is fluctuating, yet minimizes throttle pressure reserve to improve engine fuel consumption when the engine load is relatively steady.
