The reciprocating internal-combustion engine comprises at least one hollow cylinder, with a chamber inside a working fluid, the chamber has an end closed by a head and an opposite end closed by a piston that reciprocates by rectilinear motion in the chamber between a bottom dead center and a top dead center, and a device for converting the reciprocating rectilinear motion into a rotary motion of a driving shaft. The conversion device comprises at least one push rod substantially perpendicular to the shaft with a first end associated with the piston and a second end provided with pusher elements, and at least one contoured eccentric element keyed on the shaft on which a circuit element is provided which is crossed by the pusher elements and adjustment elements for adjusting sliding of the pusher elements along the circuit element so as to keep the rod and the piston in a substantially stationary configuration for a presettable rotation angle of the driving shaft.
