Abstract:
1. A variable compression ratio apparatus for an engine delivering a combustion force from an air-fuel mixture through a piston and rotating a crankshaft, comprising: a connecting rod receiving the combustion force from the piston; a pin link receiving the combustion force from the connecting rod and rotating the crankshaft; a support link disposed substantially in parallel with the connecting rod in order to transmit a part of the combustion force to the pin link; a division link receiving a part of the combustion force from the connecting rod and transmitting the part of the combustion force to the support link; a control link provided with one end coupled to the division link in order to change position of one end of the division link; and an eccentric camshaft coupled to other end of the control link in order to change a position of a rotational axis of the control link.
