摘要： The present invention relates to a structural arrangement for a stationary internal combustion engine for machines or vehicles (universal), which can use various types of fuel. More specifically, the present invention relates to an internal combustion engine with improved combustion efficiency, improved thermodynamic efficiency, reduced dimensions, an improved power-to-weight ratio that exceeds that of aircraft turbine engines using the Brayton thermodynamic cycle, and up to three times less fuel consumption and gas emissions into the environment.

摘要： Rotary vane internal combustion engine comprises of two rotors, nested in each other, placed in a cylindrical housing, wherein each rotor has at least two radial vanes rigidly attached to the rotor that form chambers for intake, compression, combustion, and exhaust. Each rotor, alternately engages with a shaft by overrunning one-way clutches and held from turning back, through the cushioning mechanisms, mounted on flywheels, which are rigidly attached on the shaft, wherein the assembled rotors from the outside are rigidly closed by flanges on each of which is mounted at least one blade, which are placed into formed cavity between rotors and caps of the housing thereby forming two cooling chambers through which coolant circulates around rotors through openings in the housing and through longitudinal grooves in the shaft. On the vanes mounted cylindrical and conical seals that exclude the need for lubrication.

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： An arrangement of a cooling medium pump of a rotary piston internal combustion engine of trochoidal-type of construction with a fluid or liquid cooled housing, with which the cooling medium is conveyed first in common and parallel through cooling hollow chambers of the casing mantle part and of a side part in a common hollow chamber and from there is conveyed by way of a cooling medium pump into another side part and from there via a thermostat into a cooler arranged on the other side part and from there it is returned into the cooling medium circulation in the housing. The cooling medium pump is arranged in the casing mantle part and a propeller or impeller thereof is arranged in a cooling hollow chamber of the other side part. A speed of rotation control regulator is arranged on a shaft of the cooling medium pump for fresh air supply and a lubricating oil pump also can be arranged on a butt end of this shaft.

摘要： A rotary engine has a substantially trochoidal-shaped housing cavity in which a rotor planetates. A cooling system for the engine directs coolant along a single series path consisting of series connected groups of passages. Coolant enters near the intake port, passes downwardly and axially through the cooler regions of the engine, then passes upwardly and axially through the hotter regions. By first flowing through the coolest regions, coolant pressure is reduced, thus reducing the saturation temperature of the coolant and thereby enhancing the nucleate boiling heat transfer mechanism which predominates in the high heat flux region of the engine during high power level operation.

摘要： A cooling system for a low noise, high power, light weight, compact rotaryxpander engine of the Wankel type having two hot zones at the operating temperatures wherein a coolant path is provided which permits the coolest coolant to be delivered at the two hottest points. This increases the heat transfer area exposed to the coolant and delivers and rejects the coolant with an absolute minimum of plumbing.
