Abstract: Systems and methods for a heat engine system are described. In one embodiment, a system comprises a heat engine compressor, a heat exchanger, and a heat engine expander. The system comprises a partial state condenser in fluid communication with the heat engine expander. The partial state condenser includes a sense reservoir to hold the working fluid, a reservoir sensor to sense an electrical property of the working fluid, and a reservoir valve. The reservoir valve is in fluid communication with the sense reservoir, the heat engine compressor, and a heat engine condenser. The system comprises a processor to execute instructions to determine a specific energy of working fluid based on the electrical property of the working fluid and control the reservoir valve based on the specific energy to maintain a two-phase saturated state point within the partial state condenser based on the electrical property.

Abstract: A pneumatic motor with dual air intake includes a pneumatic cylinder and a rotor. The pneumatic cylinder includes a cylinder body, and an elliptic-cylinder-shaped accommodating room located in the cylinder body. The cylinder body has two air inletting paths, two air venting paths, two air venting holes and a front axial hole, which communicate with the accommodating room and outside. The rotor includes a rotor body rotatably accommodated in the accommodating room of the pneumatic cylinder, a plurality of grooves parallel provided on the rotor body, a plurality of vanes accommodated in the grooves respectively, and a front axle extended from the rotor body and inserted through the front axial hole. As a result, the pneumatic motor with dual air intake is lowered in friction of the rotor when it rotates, raised in power output, and lowered in vibration when in use.

Abstract: An engine comprises a compression portion and a combustion portion. The compression portion comprises twin-screw rotors, male engaged with female. The combustion portion comprises twin-screw rotors, male engaged with female. The male compression rotor and the male combustion rotor share a same longitudinal axis, and the female compression rotor and the female combustion rotor share a same longitudinal axis. A combustion plate is disposed between the compression portion and the combustion portion, and prevents flow of gas from the compression portion to the combustion portion, except through a small orifice centrally located on the combustion plate. A valve is affixed to the male rotors adjacent to the combustion plate, covering the lobes of the male rotors and extending beyond the lobes of the male rotors. The valve controls the flow of gas from the compression portion to the combustion portion.

Abstract: An internal combustion engine having combustion chambers that rotate about a main shaft axis in a step-wise manner. A first and second rotors each have elongate pistons that are interdigitated so that when one rotor rotates with respect to the other rotor, some chambers between the interdigitated pistons are reduced in volume and other chambers are increased in volume. Respective one-way bearings connect the first and second rotors to the main shaft to incrementally rotate it. Fuel mixture and exhaust apparatus is connected to one end of the engine to feed a fuel mixture to the increasing-volume chambers and extract the exhaust from other decreasing-volume chambers. At the same time, yet other chambers are experiencing compression and ignition cycles. An oil pump is driven by the first and second rotors for circulating a lubricant from a reservoir, through the engine parts to be lubricated and then back to the reservoir to cool the lubricant.
