| 20080276613 | DISCRETE VARIABLE GEOMETRY COMPRESSOR - A variable geometry compressor having a housing, a compressor wheel and a plurality of vanes positioned between an exducer of the compressor wheel and a housing volute. The vanes are adjustable through a range of positions, but a vane actuation system is configured to actuate the vanes through three discrete positions from among the range of positions. The actuation system has an actuator that includes an actuator housing containing a diaphragm that divides a housing chamber into two portions. Through the application of a vacuum to either chamber portion, the diaphragm drives a rod to actuate the vanes between two of the discrete vane positions, while a spring returns the vanes to the third position when no vacuum is applied. The actuator is controlled by an open-loop controller. | 11-13-2008 |
| 20110239642 | Double-Acting, Two-Stroke HCCI Compound Free-Piston Rotating-Shaft Engine - This invention provides a compact, fuel-efficient internal combustion engine that can be used to provide rotating shaft output power to a wide variety of mobile and stationary applications. It is based on a two-stroke free-piston gas generator that implements the homogeneous charge compression ignition (HCCI) combustion principle for essentially constant-volume combustion, and it employs a variable piston stroke to maintain a high level of efficiency across a wide range of loads and speeds. A rotary device, which may be of either an aerodynamic or positive displacement type, converts the energetic gas stream to power at a rotating shaft. | 10-06-2011 |
| 20160376982 | Highly Efficient Two-Stroke Internal Combustion Hydraulic Engine with a Torquing Vane Device Incorporated - A highly efficient two-stroke internal combustion engine with free pistons and a simple torquing vane device instead of a crankshaft is provided. Inside the motor, hydraulic oil is used to transmit power from the piston to the torquing vane device. The engine must have at least two cylinders. The cylinders have a special shape to allow the use of valves for a continuous production of torque and power. The use of solenoids and an electronic control unit coupled with a microprocessor are given to this invention a series of advantages that a regular engine available in the open market does not have. This engine produces high torque and is suitable for any duty use. The use of hydraulic oil will guaranty a smooth, fluent and quiet operation, lubricating and protecting all components inside the motor and a total distribution of temperature along all mechanisms thus a long life. | 12-29-2016 |

| 20100186408 | ENERGY STORAGE SYSTEM FOR A HYBRID VEHICLE - An energy storage system for a hybrid vehicle, including an internal combustion engine having an output shaft and a transmission operably coupled to the output shaft, includes a reservoir containing working fluid, a first reversible pump/motor in fluid communication with the reservoir and selectively drivably coupled to the output shaft of the engine, a second reversible pump/motor in fluid communication with the reservoir and selectively drivably coupled to an output shaft of the transmission, and an accumulator containing working fluid and gas. The accumulator is in selective fluid communication with at least one of the first and second reversible pump/motors to deliver pressurized working fluid to the one of the first and second reversible pump/motors when operating as a motor, and to receive pressurized working fluid discharged by the one of the first and second reversible pump/motors when operating as a pump. | 07-29-2010 |
