Abstract:
A variable compression ratio device may include a piston assembly having double pistons of which the volume may be varied, a lifter relatively moving one piston of the double pistons with respect to the other piston of the double pistons, a guide unit engaged with the piston assembly and guiding a movement of the one piston with respect to the other piston, and a locking unit selectively coupling the one piston to the other piston.
