INTERNAL COMBUSTION ENGINE Russian patent published in 2017 - IPC F01B3/04 F02B75/26 F02B75/32 F02D15/04 

FIELD: engines and pumps.

SUBSTANCE: engine is made in the form of a group of cylinders located around the cylindrical body parallel to the axis of the rotor shaft located in the center and equipped with a cylindrical rotor with tracks, intake ports in all cylinders of the internal combustion engine (ICE) are located in the lower points and equipped with inlet valves, the inflammable mixture is prepared outside the cylinders, each cylinder of the engine contains two combustion chambers - a firing and annular prechamber located at the top of the cylinder, compression ratio necessary for operation is provided by a regulator made in the form of correction cylinders, which are communicated with the engine cylinders through the circular prechamber. The latter are made with the possibility of their complete overlapping from the cylinder cavities by the pistons of the engine near the TDC, correcting pistons installed in the correction cylinders with the possibility of changing the volume of the ring prechamber, the connecting rods pivotally connected by the upper heads with the pistons to correcting the compression ratio, and the lower heads through the hinge joints with the hub worm wheel, driven by a worm screw.

EFFECT: ensuring the smooth operation of the engine, high-quality filling of cylinders with a inflammable mixture, increasing the reliability of the reciprocating mechanism and simplifying the design of the internal combustion engine.
