Abstract: A hydrogen fueled powerplant including an internal combustion engine that drives a motor-generator, and has a two-stage turbocharger, for an aircraft. A control system controls the operation of the motor-generator to maintain the engine at a speed selected based on controlling the engine equivalence ratio. The control system controls an afterburner, an intercooler and an aftercooler to maximize powerplant efficiency. The afterburner also adds power to the turbochargers during high-altitude restarts. The turbochargers also include motor-generators that extract excess power from the exhaust.

Abstract: A pressure control valve system includes a pressure control valve, an electric actuator, an upstream pressure sensor, a downstream pressure sensor, and a controller. The electric actuator adjustably opens and closes the pressure control valve. The upstream pressure sensor measures pressure upstream of the pressure control valve and outputs a plurality of sequential upstream pressure signals over a plurality of successive periods in time. The downstream pressure sensor measures pressure downstream of the pressure control valve and outputs a plurality of sequential downstream pressure signals over the plurality of successive periods in time. The a controller receives the upstream and downstream pressure signals and outputs a plurality of sequential command signals to the electric actuator. Each sequential command signal is based on a respective one of the plurality of sequential downstream and upstream pressure signals for a respective one of the plurality of successive periods in time.

Abstract: A control device of an engine including a cylinder, a piston, a cylinder head, and a combustion chamber is provided, which includes intake and exhaust ports, a swirl control valve provided in an intake passage connected to the intake port, a fuel injection valve attached to the cylinder head to be oriented into the center of the combustion chamber in a plan view thereof, and having first and second nozzle ports, and a control unit. The control unit includes a processor configured to execute a swirl opening controlling module to output the control signal to the swirl control valve to have a given opening at which a swirl ratio inside the combustion chamber becomes 2 or above, and a fuel injection timing controlling module to output the control signal to the fuel injector to inject fuel at a given timing at which the swirl ratio becomes 2 or above.

Abstract: A fuel gas supply assembly for an internal combustion engine defines a leakage containment flowpath which includes a leakage containment space formed between the body of a gas admission valve and the wall defining the inner surface of a compartment formed in the cylinder head of the engine in which the gas admission valve is mounted. The gas admission valve is sealingly connected in fluid communication with the fuel gas conduit of a conduit assembly via a first aperture of the compartment so that both the fuel gas flowpath and the leakage containment space extend along and at least partially around a common portion of the length axis of the compartment. In another aspect, a gas admission valve includes an internal leakage containment flowpath formed by a leakage containment compartment which is interposed between the actuator and the fuel gas flowpath within the gas admission valve and sealingly connected to the leakage containment flowpath.

Abstract: In a valve apparatus, a housing includes a plurality of through holes through which a fluid flows. A first valve member opens and closes a first through hole. A second valve member opens and closes at least one second through hole. A fixed core does not move relative to the housing. A coil forms magnetic field. A first movable core moves integrally with the first valve member. When the coil forms the magnetic field, a magnetic attractive force is generated between the first movable core and the fixed core. A second movable core moves integrally with the second valve member. When the coil forms the magnetic field, a magnetic attractive force is generated between the second movable core and the fixed core. A magnetic constriction portion is provided between the fixed core and the first movable core. The second through hole is opened after the first through hole is opened.

Abstract: The present technology provides embodiments of recirculating noble gas combustion power cycles and systems including engines utilizing these power cycles. Embodiments of the cycles may include a combination of a high intake/exhaust pressure, very late or early intake valve closure, late exhaust valve opening, intake preheating using exhaust gases, sensible heat recovery, direct injection of fuel and/or oxidizer, and a condenser to remove combustion products and dissolved trace contaminant gases. An engine operating on these principles could provide motive force for electrical production, for example at power plants, or for transit, for example for ship engines. An engine operating with the cycles disclosed herein has high thermal efficiency and low cost. For example an argon power cycle using natural gas feedstock and cryogenic oxygen air separation could exceed 60% overall efficiency.
