This patent describes an apparatus for an internal combustion engine having at least one cylinder with a first axis and an attendant crankcase with crankshaft mounted therein for rotation of a throw of the crankshaft. The apparatus consists of: a piston disposed in the cylinder for movement along the first axis, a yoke connected to the piston for movement along the first axis, a sliding block to engage the yoke, the yoke and sliding block comprising means for effecting asymmetrical compression and power stroke time periods having at least a curved surface on the yoke engaging throughout the compression and power stroke time periods a mating surface on the sliding block, the curved and mating surfaces having only a single center of curvature disposed remote from the crankshaft on a side of the crankshaft which faces away from the piston and the curved surface being disposed with respect to the first axis to afford a greater time period for fuel burn during a power stroke than that for a compression stroke, wherein top dead center of the sliding block occurs after that of the piston.
