| Number | Title | Issue Date |
| 7201156 | Thermal transfer internal combustion engine A thermal transfer internal combustion engine with an air transfer cylinder located between a pair of power cylinders. The transfer cylinder has an intake valve and two transfer valves alternately feeding the two power cylinders. The power cylinders each contain a m... | 04/10/2007 |
| 6983729 | Rotary piston machine A rotary piston machine having a housing defining a prismatic chamber the cross section of which forms an oval of odd order. A rotary piston is guided in the chamber and, in each position, subdivides the chamber into two working chambers. Piston-fixed instantaneous ... | 01/10/2006 |
| 4656984 | Rotary internal combustion engine with integrated supercharged fuel-air induction An improved "Wankel-type" rotary engine wherein the same trochoidal cavity employed for effecting a four-phase internal combustion engine operation is also employed to perform a supercharging function in that air is compressed in one chamber (chambers bei... | 04/14/1987 |
| 4259932 | Internal combustion engine control system An apparatus and method for improving the combustion process of an internal combustion engine is disclosed. A prechamber containing a combustible mixture is designed to generate a torch emanating therefrom upon ignition; the torch is controlled to extend ... | 04/07/1981 |
| 4240394 | Rotary engine A rotary engine with rotary tubular valves for gas inlet and for gas outlet is described. The engine is of the type wherein at least one rotor is eccentrically rotated on a shaft in a housing with variable volume compartments between the rotor and housing... | 12/23/1980 |
| 4239027 | Rotary internal stage combustion engine A dual rotor type rotary engine with primary and secondary rotor compartments around each rotor is described. The engine operates by activating in sequence an ignition means in the presence of a fuel and air mixture in primary and secondary compartments a... | 12/16/1980 |
| 4135485 | Split-multi-unit rotary combustion engine A multi-unit rotary combustion engine in which at light loads the engine can be operated on only some of the units with those units having side intake ports and with the other units having peripheral intake ports.... | 01/23/1979 |
| 4106304 | Thermodynamic compressor A method and apparatus for the compression of compressible fluids wherein a fluid is first compressed within a constant volume with addition of heat, and then further compressed in a compressor means increasing the fluid pressure and temperature. After co... | 08/15/1978 |
| 4012903 | Internal combustion engine An internal combustion engine comprises a housing defining an air inlet opening, a first set of rotatably mounted interengaging air intake and compression rotor wheels, and an air passageway connecting said air intake and compression rotor wheels to a sec... | 03/22/1977 |
| 4004555 | Rotary piston internal combustion engine having a heat transfer phase The invention concerns an internal combustion engine having an annular cylinder and two co-axial rotors each carrying three or more equi-spaced pistons disposed in the cylinder, the rotors being constrained to undergo cyclic counterphased variations in sp... | 01/25/1977 |
| 4000721 | Rotary internal combustion engines A rotary internal combustion engine having an induction passage formed in part in the rotor of the engine, whereby the inducted air flows through and cools the rotor, has a heat exchanger adapted to cool the air flowing from the rotor before it is inducte... | 01/04/1977 |
| 3991722 | Rotary engine of the type cooled by an air-fuel mixture intake A rotary engine wherein a side port is formed in one side housing, and a main peripheral port, communicating with the side port, and a bypass peripheral port, communicating with a bypass passage formed in another side housing, are formed in a rotor housin... | 11/16/1976 |
| 3967593 | Rotary piston internal combustion engines Rotary piston engines of the kind in which the air inducted into the working chambers of the engine passes through an induction passage which is formed in part in the rotary piston of the engine, the rotary piston thereby being cooled by the air flow ther... | 07/06/1976 |
