Abstract

A variable compression piston assembly (300) includes a plurality of pistons, e.g., double ended pistons (330, 332), a rotating member, e.g., a flywheel (322) or a zero-stroke pivot member, coupled to the transition arm (310) and configured for movement relative to the transition arm-(310) along the axis of rotation of the rotating member (322).
The movement of the rotating member (322) relative to the transition arm (310) changes the compression ratio of the piston assembly (330, 332). The transition arm (310) is coupled to each of the double ended pistons (330, 332) at approximately a center of each piston (330, 332). The movement of the rotating member (322) relative to the transition arm (310) changes the compression ratio and displacement of each double ended piston (330, 332).
