FIELD: motors and pumps.
SUBSTANCE: invention relates to a crank-piston group for an internal combustion engine. Engine comprises piston head (2), piston skirt (3) surrounding bottom (2) of the piston along its circumference, and piston boss (5) for receiving connecting rod (6), the connecting rod being connected to the driving shaft of internal combustion engine (12). Piston (1) is movably connected to connecting rod (6). In this case, axial distance (A) is formed between first surface (21) facing connecting rod (6) of boss (5) of piston and second surface (22) facing connecting rod (6) of piston boss (5). In accordance with the invention, to reduce the axial distance (A), boss (5) of the piston is adapted to move connecting rod (6).
EFFECT: technical result is reduced axial distance between the connecting rod and the piston boss.
