  • Patent number: 5487265
    Abstract: A method of minimizing undesirable emissions from and acoustic pressure oscillations in a gas turbine includes the step of coordinating modulation of turbine fuel and air supply signals to maintain the fuel air ration (FAR) within a selected range. Coordination of the modulation of fuel and air supply signals includes the steps of producing a turbine fuel supply control signal in correspondence with a turbine speed error signal, generating a coordinated turbine exhaust temperature error signal by modifying a preliminary turbine exhaust temperature error signal in correspondence with the speed error signal, and producing a turbine air supply control signal from the coordinated turbine exhaust temperature error signal; the coordinated turbine exhaust temperature error signal provides coordination between the turbine fuel supply signal and the turbine air supply signal so as to maintain the fuel-air ratio of the combustible mixture being fed to the turbine within the selected range.

  • Patent number: 5394851
    Abstract: An electronic fuel injection system for providing variable injection timing for a compression ignition engine having a per cylinder displacement volume of at least 5.5 liters includes individual fuel delivery mechanisms, such as a fuel pump having a constant displacement fuel pumping chamber, and fuel injector for each corresponding cylinder, and has a timing signal generator, such as a multi-track optical encoder coupled to a camshaft, for generating a timing signal and a cylinder index signal. The invention also includes an electronic controller device, such as a plurality of individual controllers, which are responsive to various sensor inputs which include the timing signal and the cylinder index signal, for electronically controlling the individual fuel delivery mechanisms. The fuel delivery mechanisms are responsive to an output signal from the electronic controller device and provide a fuel flow volume range of between 100-1600 mm.sup.
