FIELD: engine engineering. SUBSTANCE: when piston 2 is in the top dead center, connecting rod 8 and crankshaft 11 are axially alined. The connecting rod is inclined to the vertical axis of shaft 11. Connecting rod 9 and crankshaft 13 are vertical. In further rotation of shaft 11 clockwise and shaft 13 counterclockwise, the piston moves down and, upon rotation of the shafts by an angle greater than 180°, the radii of the cranks are horizontal and directed away from cylinder 1. Connecting rods 8 and 9 point along the radii in the opposite direction. The piston is in the middle position. In further rotation of the shafts, the piston moves down to the bottom dead center and connecting rods 8 and 9 and crank are axially alined again. EFFECT: enhanced efficiency. 5 dwg
