The method comprises in a first operating mode, inducing a cooling air flow through a heat exchanger in an air conduit via a flow inducing device fluidly connected to the air conduit, the heat exchanger connected in heat exchange relationship with the power plant of the aircraft. The method comprises, in a second operating mode, bypassing the cooling air flow from the flow inducing device via a selectively closable air outlet of the air conduit downstream of the heat exchanger. A cooling system for an aircraft power plant is also disclosed.

摘要： A rotary engine casing having at least one end wall of an internal cavity for a rotor including a seal-engaging plate sealingly engaging the peripheral wall to partially seal the internal cavity and a member mounted adjacent the seal-engaging plate outside of the internal cavity. The member and seal-engaging plate having abutting mating surfaces which cooperate to define between them at least one fluid cavity communicating with a source of liquid coolant. When the casing includes a plurality of rotor housings, the end wall may be between rotor housings. A method of manufacturing a rotary engine casing is also discussed.

摘要： A Circle-Ellipse Engine comprises a stationary circular outer Housing having a fixed elliptical inner cam surface, and a separate internal round Rotor partitioned into equal segments that are populated by identical movable radial Vanes. During rotation, the end of the Vanes are positioned a constant distance from the elliptical inner cam surface of the Housing. The internal round Rotor has the same radius as the minor axis of the elliptical inner cam surface. During rotation, a variable height cavity is created representing the difference between the major and minor axes of the elliptical inner cam surface and the Rotor face.The position of the radial Vanes is guided by the slots in the symmetrical Rotor, extending to the elliptical inner cam surface of the Housing. The precise extension is governed by a pin track machined into the dual End Plates.There are no pistons, camshaft, timing chains, valves, valve lifters, rocker arms, connecting rods, or wrist pins. As a benefit, size and weight are significantly reduced when compared to a reciprocating engine of similar horsepower. Normal aspirated air is continuously drawn into the engine when an adjacent pair of radial Vanes passes the air inlet port. Similarly, exhaust products are expelled after a combustion event when the pair of adjacent Vanes passes over the exhaust port.The resultant geometer results in a continuous implementation of the Otto Cycle; namely intake, compression, expansion or power stroke, and exhaust during a single rotation of the internal round Rotor.Because the Otto Cycle is executed each revolution of the Rotor, the Circle-Ellipse Engine achieves the same power as a conventional reciprocating engine of the same displacement and compression ratio, at half the RPM. This implementation greatly reduces component ware and extends the life and maintenance cycle by a factor of four. As a side benefit, the power losses and vibration common to all reciprocating engines are eliminated.

摘要： A heat transfer system for use in an internal combustion engine and related methods are disclosed. The heat transfer system may be configured to absorb and transfer heat from a combustion chamber of an internal combustion engine. The heat transfer system may also be configured to reintroduce absorbed and/or transferred heat into the internal combustion engine via a fuel injector or another suitable device. Removal of the heat from the combustion chamber may reduce a quantity of work required or used for compression of a first combustion fluid, increase a charge density in the combustion chamber, and/or increase the compression ratio of the engine. Additionally, the heat transfer system may be designed such that it may be used to retrofit an existing internal combustion engine.

摘要： A triangular piston is journalled rotating in a planetary manner upon an eccentric of an eccentric shaft journalled in a housing of a rotary piston internal combustion engine of trochoidal type of construction with a fluid cooled system in the housing with a multi-arcuate casing runway surfacing of which the side walls have the eccentric shaft passing therethrough. An eccentric bearing is cooled directly by a cooling medium conveyed via a bypass of the cooling system of the housing branched off from the cooling system and the cooling medium is conveyed via hollow spaces in the eccentric shaft into a location at the eccentric journalling the triangular piston. The cooling medium is supplied and carried away via lines opening into an annular groove extending around the eccentric in a location below and radially inwardly of the eccentric bearing. A supply line is provided in the eccentric shaft for supply of cooling medium to the annular groove and this supply is continuously in connection and in communication with at least one radial bore to the annular groove in a region of the eccentricity maximum of the eccentric and in a region of the eccentricity minimum of the eccentric there is arranged at least one bore leading back from the annular groove, which latter groove opens into an axial return flow line in the eccentric shaft and that furthermore the feed and return lines are connected to the bypass of the cooling system of the housing.

摘要： The improved system for liquid cooling of a rotor of a rotary piston mechanism applies to those types having two housing walls spaced apart by a trochoidal shaped peripheral wall to define a multi-lobed cavity within which a multi-cornered rotor is eccentrically supported for planetary movement, and in which the rotor has a hub portion and peripheral wall portions defining therebetween cooling spaces which communicate with the area exteriorly of the rotor through an opening adjacent each end of the hub portion. The improved rotor cooling system comprises a cooling liquid discharge nozzle disposed in at least one of the housing walls and connecting the discharge nozzle to a source of pressurized cooling liquid. The discharge nozzle is positioned so as to direct emitted cooling liquid into the adjacent rotor opening and the cooling spaces in the rotor.In a narrower aspect of the invention a regulator and valve assembly is provided to control flow of cooling liquid to the discharge nozzle in accordance with the pressure conditions of the cooling liquid and temperature and load operating conditions of the engine.
