Variable compression technology (VCT) is achieved several ways.

You can play with the cam shaft rotation setting on the fly. Chrysler/Fiat uses a hydraulic system on the intake valves to achieve VCT.

You can add a second lever arm assembly to the piston rod to vary the piston stroke.

Here's how the Murnao's VCT works:

Also, you can find more info on VCT searching on Wikipedia:

Have a good day.
