The subject of invention is a method to derive specifications for an eccentric cam located in a void within the piston of an IC engine which will have parallel faces abutting the cam. These faces will drive the cam in a rotary fashion and transmit the energy produced by the piston by means of the cams axle. The method employs two variables: (a) the radius of the cam; (b) the degree of its eccentricity. These determine the slope of these abutting faces which will be rotated from the plane that is perpendicular to the axis of reciprocation. This slope is eccentric specific and produce a unique solution in each instance. This slope will be the same regardless of the cams radius. The result is an engine with no lateral oscillations.
