How to be able to adjust i. c. engine compression while it is running?

This is the contra piston to adjust ratio of compression in model diesel engine to
increase or decrease heat of compression who are affected by timing and temperature of ignition.

I have a 4-stroke model diesel engine that adjusts the compression by lowering/raising the crankshaft! The crank is mounted off-center in a round piece that can be rotated by means of a lever. [ame]https://www.youtube.com/watch?v=kWnvMGz8zYg[/ame]
