摘要： A volumetric expander configured to transfer a working fluid and generate useful work via a variable drive system is disclosed. The expander includes an inlet port configured to admit relatively high-pressure working fluid and an outlet port configured to discharge to a relatively low-pressure working fluid. The expander also includes first and second twisted meshed rotors rotatably disposed in the housing and configured to expand the relatively high-pressure working fluid into the relatively low-pressure working fluid. Each rotor has a plurality of lobes, and when one lobe of the first rotor is leading with respect to the inlet port, one lobe of the second rotor is trailing with respect to the inlet port. The expander additionally includes an output shaft coupled to the variable speed drive that can deliver power from the output shaft to the engine and/or to a load storage device.

摘要： A four-cycle internal combustion engine has a bellows leaf spring working in a compression mode or a tension mode. The leaf spring is connected to a crankshaft and forms a movable portion of a bellows chamber that receives exhaust gases from an engine cylinder. As the exhaust gases transfer from the cylinder to the bellows chamber, the gases push on the leaf spring thereby transferring energy to the crankshaft.

摘要： An internal combustion engine includes first and second cylinder assemblies each to repeatedly carry out combustion cycle including intake, compression, combustion with expansion, and exhaust processes. In a surcharging system of the invention, the first cylinder assembly is coupled to the second cylinder assembly in gaseous communication to apply a charge of exhaust gas produced from a first combustion cycle of the first cylinder assembly to a compression process of a second combustion cycle of the second cylinder assembly. In a supraignition system of the invention, the first cylinder assembly is coupled to the second cylinder assembly in gaseous communication to apply a charge of ignition gas produced from a first combustion cycle of the first cylinder assembly to a compression process of a second combustion cycle of the second cylinder assembly. Buffer vessels coupled in gaseous communication with corresponding cylinder assemblies are also used in surcharging and supraignition processes.

摘要： Rotary valve system for controlling communication with a port in an internal combustion engine which, in one disclosed embodiment, has a crankshaft, compression and expansion pistons connected to the crankshaft for reciprocating movement within compression and expansion chambers, a combustion chamber in which air from the compression chamber is combined with fuel and burned to produce an increased gas volume. The valve system has an outer valve member which is rotatively mounted in a bore and has an opening which moves into and out of communication with the port as the outer valve member rotates, an inner valve member rotatably mounted within the outer valve member with an opening at least partly overlapping the opening in the outer valve member, a flange extending along one edge of the opening in the inner valve member and through the opening in the outer valve member for sealing engagement with the wall of the bore, and means for effecting rotation of the valve members to change the degree of overlap between the openings and thereby control the timing and duration of communication between the openings and the port.

摘要： Internal combustion engine and method with compression and expansion chambers of variable volume, a combustion chamber, a variable intake valve for controlling air intake to the compression chamber, a variable outlet valve for controlling communication between the compression chamber and the combustion chamber, means for introducing fuel into the combustion chamber to form a mixture of fuel and air which burns and expands in the combustion chamber, a variable inlet valve for controlling communication between the combustion chamber and the expansion chamber, a variable exhaust valve for controlling exhaust flow from the expansion chamber, means for monitoring temperature and pressure conditions, and a computer responsive to the temperature and pressure conditions for controlling opening and closing of the valves and introduction of fuel into to the combustion chamber to optimize engine efficiency over a wide range of engine load conditions. The relative volumes of the compression and expansion chambers and the timing of the valves are such that the pressure in the combustion chamber remains substantially constant throughout the operating cycle of the engine, and exhaust pressures are very close to atmospheric pressure regardless of the load on the engine. The engine runs so quietly and burns so cleanly that in some applications it may not require a muffler and/or a catalytic converter.

摘要： A method for combusting fuel in an engine involving decreasing a first volume of a homogeneous lean fuel/air charge to a second volume, in two stages, while increasing the pressure and temperature of that charge (a compression process having a chosen compression ratio), then increasing the pressure at constant volume while adding heat until a predetermined temperature is obtained, increasing the third volume of gas to a fourth volume, in two stages while decreasing the pressure at the predetermined temperature (an expansion process having a chosen expansion ratio much greater than the compression ratio), decreasing the pressure to atmospheric pressure while removing heat under constant volume, and finally decreasing the volume of gas to the first volume while removing heat under constant pressure to complete an over expanded, cycle. Also disclosed is an engine employing said over expanded, two-stroke HCCI cycle.
