Okay--

I'm moderately fascinated..

Doesn't the engine create a heat differential between the "intake" and "exhaust" piston?? Seems like the intake side of the engine wouldn't heat as quickly, and would cause fatigue issues-- maybe not..

Do they tie the cranks together with a chain, gears or what??

Were these USED in something-- or were they strictly an experimental engine??
