Abstract: The invention relates to power take-off devices for internal combustion engines and can be used, in particular, in different vehicles for taking power from reciprocating internal combustion engines. The present power take-off device for an internal combustion engine comprises at least two pairs of transfer mechanisms, coupled to the pistons of an engine, wherein a transfer mechanism is adapted to convert the reciprocating motion of its corresponding piston into rotary motion of a corresponding power take-off shaft. Each transfer mechanism comprises a means of setting rotation, which is mounted on a shaft connected to the piston, said means comprising a transfer component with at least one continuous, wave-like, vertically guiding track in the form of a guiding contact path, and a running wheel which moves along the contact path and has a fixed vertical position. The device provides an increase in engine efficiency of up to 50% and reduces the number of revolutions for similar levels of power output.
