[TheForge] Rivets & heat

[terry l. ridder]

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.
