INTERNAL COMBUSTION ENGINE (VERSIONS) Russian patent published in 2011 - IPC F02B75/32 F01B9/04 F16H19/04 

FIELD: engines and pumps.

SUBSTANCE: internal combustion engine (ICE) comprises cylinders (1, 11), pistons (2, 10), an output shaft (12), systems of cooling, lubrication, supply, ignition, pistons (2, 10). The pistons (2, 10) are connected in pairs, via rods (3, 9) with a frame (5). The frame (5) is arranged with upper (6) and lower (7) geared racks. Longitudinal axes of upper (6) and lower (7) racks are displaced relative to each other and relative to the axis of pistons (2, 10). There are wheels (15, 16) are installed at the output shaft (12). Geared racks (6,7) engage with geared sectors (17, 18) of wheels (15, 16). If one piston (10) is in the upper dead point, then the other one (2) - in the lower one. Conversion of reciprocal motion of pistons (2, 10) into rotary motion of the output shaft (12) takes place as a result of displacement of the frame (5) with geared racks (6, 7). Also an ICE is represented in the invention, where the geared racks (6, 7) and geared sectors (17, 18) of the wheels (15, 16) are magnetised. Also one of the geared pair elements may be magnetised.

EFFECT: reduced friction between geared sectors of wheels and geared racks.
