DESIGN OF FOUR-STROKE ENGINE WITH NO CON ROD RUNNING ON DUST-LIKE FUEL Russian patent published in 2010 - IPC F02B45/02 

FIELD: engines and pumps.

SUBSTANCE: invention relates to engine production, particularly to four-strokes ICE running on dust-like fuel and can be used in vehicle drives. Proposed engine consists of cylinder block, cylinder block liner, combustion chamber, electric starter, separator and nozzle. It incorporates also main pneumatic accumulator, igniter, receiver communicated with nozzle, compressor communicated with Ranque tube to separate airflow into cold flow forced into pneumatic heat exchanger and hot flow sent into receiver communicated, via pipeline, with proportioner with bin. Discharge pipeline communicates with compressor suction filter. Diaphragm made from sheet high-temperature steel in the form of hollow disk for cooling fluid circulation is arranged in combustion chamber between cylinder block liner and head. When deformed, said diaphragm tightly abuts on concave surface of engine liner. Combustion chamber communicates, via pipeline, separator and check valve, with above-diaphragm space of the main pneumatic accumulator. Outlet pipeline of the latter communicates with pneumatic turbine via cock. Pneumatic turbine drive shaft supports a coupling fitted thereon. Pneumatic accumulator outlet pipeline communicates with the other turbine. Drive shaft is coupled with reduction gear drive shaft furnished with lever to shift rpm of idle gear and cam shaft gear driven shaft.

EFFECT: engine with no con rod gear, expanded range of applicable dust-like organic and inorganic fuels.
