INTERNAL COMBUSTION ENGINE Russian patent published in 2012 - IPC F02B75/24 F02B75/32 

FIELD: internal combustion engine.

SUBSTANCE: invention concerns mechanical engineering, in particular to engine-building and can be used on vehicles. The internal combustion engine contains a case (7), coaxial opposed cylinders (12, 13, 14, 15), pistons (4), rods (16), crankshaft (1), output shaft (8, 9), and planetary linear transforming mechanism. The planetary linear transforming mechanism is placed in the case (7). The planetary linear transforming mechanism consists of the satellites (2, 3) internally engaging with fixed gears (5, 6), and cage (10, 11). Radiuses pitch line planet of satellites (2, 3) and fixed gears (5, 6) are equal g and 2g accordingly. Satellite gears (2, 3) are fixed at the ends of crankshaft bearing surface (1). Crankshaft (1) is supported by bearings placed in cages (10, 11). A crankshaft cheek is equal g of cage (10, 11) installed on supporting bearings. Distance between axes of crankshaft bearing surface (1) and a rotation axis of cages, and output shafts equals to g. The pistons (4) opposed cylinders (12, 14 and 13, 12) are in pairs fixed on the ends of rods (16). Piston stroke on cylinder axes (12, 13, 14, 15) is equal to 4 g.

EFFECT: exception of lateral force affecting the cylinders and the bending moment on crank bearing surfaces.
