INTERNAL COMBUSTION ENGINE Russian patent published in 2016 - IPC F02B75/04 F02D15/04 

FIELD: engines and pumps.

SUBSTANCE: invention can be used in internal combustion engines used in automobile transport. Internal combustion engine includes cylinders block (1) with fixed cylinder sleeves (2) and with cooling liquid cavities (3), cylinder block head (4) with combustion chambers (5) located above cylinders block (1), as well as pistons (6) arranged inside fixed cylindrical sleeves (2). Pistons (6) are made with possibility of reciprocative movement in fixed sleeves (2). Fixed sleeves (2) extend above cylinders block (1) upper plane. On fixed casings (2) protruding parts cylindrical surfaces grooves are made in form of slots accommodating o-rings (7). In cylinder block head (4), coaxially to fixed sleeves (2) movable cylindrical sleeves (4) are installed, which inner diameter is commensurate with of fixed cylindrical casings (2) outer diameter installed in cylinders block (1). In cylinders block (1) upper part guide pins (9) are fixed, threaded to openings (10) in cylinders block head (4). Cylinders block head (4) is made with possibility of reciprocative movement above cylinders block (1) at distance, which is limited by sleeves (2) projecting part height. Cylinders block head (4) is connected with actuating hydraulic cylinders (12) by rods (11) located in opposite parts of cylinders block (1).

EFFECT: technical result consists in possibility of changing engine operating modes depending on operating load and physical-mechanical properties of used fuel.
