INTERNAL COMBUSTION ENGINE Russian patent published in 2017 - IPC F02B33/06 F02B33/22 

FIELD: engines and pumps.

SUBSTANCE: air is sucked through the intake valve 17 into one part of the cavity between the piston 8 and the cylinder cover 10, and in the right part of the cylinder 11 cavity the air is compressed by the piston 9. When the piston reaches the 0.96 stroke mark, the window 16 will start to open, the combustion products from the left side of the cylinder 11 will flow into the atmosphere, the pressure in this part of the cavity will lower and the air compressed by the piston 8 along the duct 13 through the intake valve 14 will rush to the left side of the cylinder 11, carrying out its purging. The injector injects fuel, which ignites and starts to burn, and the resulting combustion products press against the piston 9. When the shaft 3 passes the corner 110° the piston 9 will again be at the 0.96 stroke mark, moving already in the opposite direction, and the piston 8 will be at 0.61 mark and will continue to move in the same direction. And window 16 will begin to close completely, and blowdown will be finishing. The air will then flow into the left part of the cylinder 11 via the channel 13 through the inlet valve 14, increasing the amount of air in the latter. As the piston 8 reaches the dead point, air injection into the right part of the cylinder 11 cavity will end, at that, its piston will be at ~the 0.4 stroke mark and will continue to move, compressing the air in front of him. Once the piston 9 is near 0.03, the window 16 will begin to open slightly, releasing the combustion products from the right side of the cylinder 11 cavity, the pressure in it will drop and the air compressed by the piston 8 will rush through the inlet valve 15 performing a purge. At the same time, a fuel injected by the left nozzle will ignite and begin to burn. Then the described cycle will be repeated.

EFFECT: simplification of design, expansion of functionality and improvement of performance characteristics.
