INTERNAL COMBUSTION ENGINE Russian patent published in 2015 - IPC F02B59/00 F02B75/24 

FIELD: engines and pumps.

SUBSTANCE: invention relates to propulsion engineering, particularly, to ICE production. Engine comprises hollow rod to couple the pistons in diameter equal to that of the piston and provided with zigzag-like closed grooves of rectangular cross-section on both sides of a long bore to receive inlet pipe at its central part for rollers to contact with rollers fitted in hubs of conical gears coaxial therewith to run in rolling bearings. Said conical bearings are engaged with the third conical gear to transmit torque to power takeoff shaft. Outer surface of piston bottom-intake valve is provided with shaped ledge aligned with cylinder axis to make a supersonic nozzle with prechamber outlet bore at the moment of ignition to add to reliability of the assy. Application of fundamentally new process of compressor-less supercharging ups the ICE output and efficiency.

EFFECT: air cooling of ribbed sleeves displacing across the flow at exhaust stroke ups the cooling efficiency and strength of sleeves and decreases the ICE total weight.
