TWO-STROKE ENGINE WITH SLEEVE GAS DISTRIBUTION Russian patent published in 2020 - IPC F01L5/10 F01L5/20 F02B33/00 

FIELD: machine building.

SUBSTANCE: invention relates to the field of two-stroke internal combustion engines with asymmetric gas distribution phases. Two-stroke engine with sleeve gas distribution contains at least one cylinder (1), in which sleeve (2) of gas distribution is arranged, kinematically connected to first crank shaft (3) with possibility of reciprocating movement along geometrical longitudinal axis (4) cylinder and reciprocating rotational movement around geometrical longitudinal axis (4) of cylinder. Inside sleeve (2) of gas distribution head (9) of cylinder connected to cylinder (1) and piston (7) connected to second crank pin (10) of crankshaft with possibility of reciprocating movement inside sleeve (2) of gas distribution are arranged. Sleeve (2) is stepped to form working surface (5) of annular piston (6) and cylindrical cavity, in which piston (7) with bottom (8) is arranged. Cylindrical cavity is made with diameter smaller than diameter of sleeve (2) of gas distribution, in which cylinder head (9) is arranged. In cylinder (1) and sleeve (2) there are outlet openings (12), (13), which are arranged with the possibility of their passage cross section change during sleeve (2) movement. In annular piston (6) blowing channels (14) with openings (15) are made, which are arranged with possibility of change of their cross-section by edge of piston (7) with bottom (8).

EFFECT: technical result consists in increase of time for charge combustion with provision of asymmetric phases of gas distribution in two-stroke process.
