INTERNAL COMBUSTION ENGINE Russian patent published in 2019 - IPC F01B9/02 F02B75/32 

FIELD: engine building.

SUBSTANCE: internal combustion engine comprising a conversion mechanism of piston reciprocating movement into the crankshaft rotational movement, by means of plane-parallel movement of the rocker arm having a support end pivotally connected to the correcting crank, at that, its other end is connected by means of a piston rod to a piston located in the cylinder, which is arranged in crankcase, wherein lever-rocker arm has in its housing axis, pivotally connected via connecting rod with crankshaft crank, wherein piston rod is connected to rocker arm via fixed eccentric hinge, support end of rocker arm is articulated with eccentric shaft connected with crankshaft by means of gear-type drive to provide synchronous rotation with angular speed twice less than speed of crankshaft.

EFFECT: invention is aimed at production of internal combustion engine, which stably operates in all ranges of load and crankshaft rotations, without "Miller losses", by four-stroke cycle, in which the expansion degree is greater than the compression ratio, with the possibility of realizing the working process (WP), both Otto and Diesel in two revolutions of the crankshaft.
