| 20090145397 | Rotary engine systems - This rotary internal combustion engine has two rotatable vane type pistons mounted for axial rotation in a sealed casing. In an exemplary cycle, one piston is released to rotate at or prior to initiating combustion in the combustion space between the two pistons, while the other remains fixed. As the free piston rotates around to the position where the fixed piston is located, it drives exhaust from a prior cycle out of an exhaust outlet and then compresses air towards the combustion space. The roles of the pistons are reversed on the next cycle. Two units may be operated in tandem so that the power stroke of one unit provides power to help finalize the cycle of the other. Hydrogen is used as a preferred fuel, and water preferably serves as a lubricant. | 06-11-2009 |

Multiple combustion chambers are provided for increased torque and varied firing frequencies. Multiple ignitions can be performed per chamber per revolution to provide high torque. The average firings per revolution and fuel and air introduction may be controlled to provide various frequencies and patterns of combustion chamber activity and operating pressures to optimize performance and economy. | 01-07-2010 |

| 20100269782 | Augmenter For Compound Compression Engine - A rotary engine has a first rotary unit and a second rotary unit. The first rotary unit has a chamber containing a remaining compressed air charge. After combustion in the second rotary unit, the resulting second unit exhaust is in fluid communication with said remaining compressed air charge via a second passageway. An injector is in fluid communication with said remaining compressed air charge in the first rotary unit. The injector injects fuel into the mixture containing the remaining compressed air charge in the first rotary engine and the second unit exhaust from the second rotary engine. This mixture is combusted either with a spark or via auto (diesel) ignition. In this way, the engine produces additional useful work by combusting the remaining compressed air charge and additional fuel. Alternatively, the injector described in the first rotary unit may be located in the second passageway. The injector in the first rotary unit or in the second passageway may be selectively activated throughout the engine's mission. | 10-28-2010 |

| 20130186366 | FUEL REACTIVITY STRATIFICATION IN ROTARY DIESEL ENGINES - A first fuel charge having low reactivity (low cetane number) is injected into a rotary engine, e.g., a Wankel engine, sufficiently early during the intake stroke that a subsequent higher-reactivity injected fuel charge forms one or more stratified high-reactivity regions within the engine chamber. Compression ignition then begins at the high-reactivity regions and propagates to the lower-reactivity regions. Appropriate choice of the timings, quantities, and other parameters of the injections can allow control of the timing and rate of combustion, such that work output can be maximized, unburned fuel can be minimized, and chamber temperature can be controlled to reduce heat losses and NOx emissions. As a result, rotary engine efficiency can be enhanced while emissions are reduced. Since the invention can be implemented in a lightweight and compact rotary engine, it is well suited for use in hybrid and compact vehicles. | 07-25-2013 |
