123212000 | With plural compression volume means | 7 |
20080264379 | Rotary Engine - A rotary engine is disclosed. The rotary engine of the present invention includes an engine body ( | 10-30-2008 |
20090255506 | Rotary internal combustion engine - The present invention relates to a rotary internal combustion engine that extracts power from expansion gases supplied to a rotary power-extraction assembly, and related methods. The disclosed engines include a compressor assembly, a combustion assembly, and a rotary power-extraction assembly. The compressor assembly supplies a compressed charge to the combustion assembly. The combustion assembly initiates combustion and discharges expansion gases to the rotary power-extraction assembly. A rotary power-extraction assembly can be configured to include an annular chamber where expansion gases drive a power rotor. | 10-15-2009 |
20110132315 | Multi-cylinder reciprocating rotary engine - A highly efficient, low weight-to-power ratio and adjustable high compression, gasoline or diesel internal combustion engine consisting of a multitude of cylindrical casings parallel to each other or aligned sequentially on one axle. Each casing having one radially extending vane affixed to a shaft rotatably mounted within the casing upon two end plates and one longitudinally extending wall affixed on the inside of the casing. The casing and/or the end plates equipped with plurality of ports and conduits which enable communication between interior chambers of the cylinders, allowing for intake of combustible air-fuel mixture and exhaust thereafter. Ignition means delivering a spark at the end of each working cycle. An extendable and adjustable connecting rod assembly converting the oscillating bi-directional rotary motion of the power output shaft into a continuous unidirectional motion of the main shaft. A self lubricating mechanism incorporated into the engine. | 06-09-2011 |
20110174262 | ROTARY ENGINE WITH EXHAUST GAS SUPPLEMENTAL COMPOUNDING - A rotary engine which provides a supplemental phase of compression between a first phase of compression and a second phase of compression. | 07-21-2011 |
20110259296 | ROTARY INTERNAL COMBUSTION ENGINE - A rotary engine includes a compressor assembly and two power assemblies that receive compressed air from the compressor assembly. Each assembly includes at least two intermeshing rotors. The rotors of the compressor assembly compress air, either alone or in an air/fuel mixture, in a compression chamber located in that assembly. The compressed air is transferred to the expansion chambers of the power assemblies, where fuel is ignited to initiate a power stroke. A line bisecting the axes of the rotors of the compressor assembly is inclined at an acute angle relative to a line bisecting the axes of the rotors of the power assemblies. The power assemblies operate 180° out of phase with respect to one another to minimize power fluctuations in the engine. | 10-27-2011 |
123213000 | In series | 2 |
20080216792 | POSITIVE DISPLACEMENT ROTARY VANE ENGINE - The present invention is an engine, which includes a positive displacement compression process, a variably fueled, continuous combustor and/or heat exchanger, and a positive displacement, work-producing expander. This arrangement avoids the traditional stochiometric mixture requirements utilized in spark-ignition based engines and the emission problems associated with diesel engines. | 09-11-2008 |
20100319653 | REDUCED FRICTION ROTARY COMBUSTION ENGINE - An axial vane rotary combustion engine includes various performance improving features. These features include fluid film bearings that enable the vane assemblies to react large loads, a dual vane assembly configuration that share vane loads over two cylindrical bearing supports, a vane actuation mechanism that provides positive actuation even with cam surface tolerance variations, and various features to reduce friction to thereby improve efficiency and reduce heat generation. | 12-23-2010 |
