Abstract
A variable compression ratio (VCR) apparatus, may include a piston, a connecting rod having one end coupled to the piston through a piston pin so as to transmit a motion of the piston to a crank shaft, a pair of first and second eccentric links having one ends eccentrically connected to the one end of the connecting rod through the piston pin, dual swing links having one ends connected to the other ends of the first and second eccentric links, respectively, so as to pivot the eccentric links with respect to the piston pin, and connecting assembly connecting the one ends of the first and second eccentric links each other.
