PISTON TWO-STROKE ENGINE Russian patent published in 2019 - IPC F02B75/32 

FIELD: engine building.

SUBSTANCE: disclosed piston two-stroke engine relates to machine building. Piston two-stroke engine consists of housing with cylinders, pistons, mechanism for conversion of rotary movement of shaft into translational movement of piston and is characterized by that on rectilinear shaft with cams and squares on eccentrics, rods with slots and support planes located at angle from 10 to 30° to axes of rods, move in housing support bushings, determining position and direction of movement, pistons with combustion chambers move, without touching walls of cylinders, rods transmit movement to square, rotating on axis of eccentric, and kinetic energy of motion is transmitted through square of eccentric axis and from one rod to another, cylinders with combustion chambers are blown clean compressed air, and cooled by air mixed with water vapor from receiver and under-piston volume.

EFFECT: at low eccentricity high fuel combustion frequency and increased engine power are created.
