Abstract: A system includes a controller configured to control a semi-closed power cycle system. The controller is configured to receive at least one of a first signal indicative of an oxygen concentration within a first gas flow through a primary compressor, a second signal indicative of power output by the semi-closed power cycle system, a third signal indicative of a temperature of a second gas flow through a turbine, and a fourth signal indicative of a mass flow balance within the semi-closed power cycle system. The controller is also configured to adjust at least one of the first gas flow through the primary compressor, a fuel flow into a combustor, a fraction of the first gas flow extracted from the primary compressor, and an air flow through a feed compressor based on the at least one of the first signal, the second signal, the third signal, and the fourth signal.

Abstract: A fuel injector assembly is provided which includes a pressurization control valve assembly and a timing control valve assembly. A pressure actuated needle valve is positioned between the pressurization and timing control valves. Pressure within the injector is controlled by opening and closing such valve assemblies. In particular, when the pressurization control valve assembly is open and the timing control valve is closed there will be pressure equilibrium within the injector and a spring will hold the needle valve closed. When the pressurization and timing control valves are both closed, fuel in the injector will be pressurized. Upon opening the timing control valve assembly, there will be a net upward force which will open the needle valve. Closing of the timing control valve assembly will create a net downward force closing the needle valve.
