Abstract: A split-cycle internal combustion engine includes a variable displacement compressor having two or more cylinders, an adjustment mechanism for varying the displacement volume of the compressor and possibly the phase between the compressor and the motor, and a rotary motor having two or more expansion chambers. A passage valve system located between the compressor and the motor transfers working fluid and combustion exhaust products, and, in addition, mechanically and thermally isolates the compressor from the high pressures and temperatures present in the motor.

Abstract: A rotary engine includes an insert having a pilot subchamber defined therein and communicating with the internal cavity of the engine. A pilot fuel injector has a tip in communication with the pilot subchamber. An ignition element extends into an element cavity defined through the insert adjacent the pilot subchamber. The element cavity is in communication with the pilot subchamber through a communication opening defined in the insert between the element cavity and the pilot subchamber. The communication opening is smaller than a portion of the ignition element adjacent the communication opening such as to prevent the portion of the ignition element from completely passing through the communication opening upon breaking off of the portion of the ignition element from a remainder of the ignition element. An outer body for a rotary engine and a method of combusting fuel in a rotary engine are also provided.

Abstract: A rotary engine including a compressor unit and an expander unit, a stator having cylindrical inner wall with intake and outlet ports, a hinged gate which fits into the stator inner wall, multiple sealing-strips being loosely embedded within the stator inner wall and backed by elastic force, an eccentrically rotating rotor with a freely rotatable rotor-sleeve which engages with the hinged gate while separating pressure and non-pressure area incident to the expansion and contraction of the working space, the above components being sandwiched between end-plates, perfect dynamic sealing without solid sliding friction, a gate-operated valve conducting the working fluid from the compressor unit into the expander unit via conduit ports in duly timing. The combination of the two units performs a full and extended power cycle simultaneously during each revolution of a common straight shaft.

Abstract: An engine configuration that uses multiple opposing piston pairs to form respective expansion chambers for expanding a gas within to move the pistons to drive a main shaft. The engine can be configured to operate as an internal combustion engine that uses diesel fuel, gasoline, or natural gas, or it can be configured as an expander to convert high pressure high temperature gas to rotary power. The pistons may be mounted on the circumference of one or more disks. For any given set of choices of numbers of pistons and sizes of pistons, disks, and gears, there are disclosed dimensional constraints useful for more efficient functioning of the engine. This engine can be provided with a compact design which results in high power to weight ratios.
