INTERNAL COMBUSTION ENGINE Russian patent published in 1998 - IPC

FIELD: mechanical engineering; engine units. SUBSTANCE: engine has cylinder block with fixed pistons and horizontally movable cylinders. Reciprocating motion of cylinders is converted into rotary motion of output shaft by means of gear train. Engine has timing hydraulic system, combined lubricating and cooling system, fuel and ignition systems. Reciprocating motion of cylinders of cylinders is transmitted through rod to double-acting piston pump with use of liquid high pressure for hydraulic drive. Segment cutoff are made on pistons of engine and hydraulic pump. EFFECT: increased efficiency, service life of engine, reduced toxicity of exhaust gases. 4 cl, 3 dwg
