An internal combustion engine that replaces the throw journal of a crankshaft with a contour that is dynamic rather than static. The contour is such that three cycles of engine operation is not affected, i.e. exhaust, intake, and compression. The contour deviates only during the power stroke where an increased incidence to the circular for approximately ninety degrees of rotation is incorporated. This defers from previous attempts by eliminating complex geometries such as epitrochoidal, sinusoidal, or the elliptical that by their nature negatively affect the exhaust, intake, and compression strokes of the Otto cycle when compared to the traditional crankshaft. Additionally, the deviation from the circular orbit during the power cycle optimizes to a larger extent the leverage available for peak thermodynamic pressures in the cylinder in the brief optimum time afforded by that pressure. Compressors so configured would also be more efficient by reducing the energy requirements of an input shaft.
