If you mean how does it work if an engine has a compression ratio of 10/1 it means when The piston is at the top of its stroke the fuel air mix is compressed 10 times smaller.Go to howstuffworks .com auto section you can see it explained.

If you refer to piston engines, the compression is the pressure generated in the cylinders after the air-fuel mixture has been exploded. this pressure pushed the piston downwards and cause the engine to move.
To prevent this pressure to escape, some O rings are placed between the piston and the cylinder.
Compression tests are performed by removing a plug and inserting a pressure meter instead.

do you mean the compression ratio ? it's the volume of the cylinder at bottom dead centre divided by the volume of the cylinder at top dead centre
