Abstract
An internal combustion engine variable compression ratio system. The system includes an inner piston connected to a connecting rod, an outer piston fitted around the outer periphery of the inner piston so that the outer piston can slide only in the axial direction, and a retaining ring fixedly provided on the outer piston so as to axially oppose a head portion with the inner piston interposed between the restricting means and the head portion. Also included are a first cam mechanism disposed between the inner piston and the head portion for controlling a first axial spacing therebetween, and a second cam mechanism disposed between the inner piston and the retaining ring for controlling a second axial spacing therebetween.
