Hello

consider an internal combustion engine.
anywhere from 1,2, 3, 4, 6, 8 cylinders.
those cylinders are holes
those holes are occupied by pistons.
those pistons are connected to connecting rods.
which are connected to a crankshaft.

I am going to assume that everyone on the list has numerous years experience
with internal combustion engines. I will stick to 4-cycle engines.

the engine works by controlling the combustion of a fuel and air mixture.
this combustion heats the engine block up above the boiling point of water &
antifreeze mixture. if the cylinder were to become smaller the piston would
seize. the piston and rings are going to expand. That is the whole purpose
of the rings to keep the compression at operating temperature.

the cylinder diameter expands, no doubt about it.
