I like steam engines running super slow, lets you view the works.
I the sound and looks of a open horizontal hit and miss engine.. Mine runs slow but still the conrod and piston are moving pretty quick.
Imagine a slow running big flywheel'd horizontal engine running at say 200rpm, now imagine the same engine with a 10:1 gearbox running the flywheel at the same 200 rpm but the crank and piston running at 20rpm. I think the sound of the powerstroke running up the flywheel and then the long coastdown as exhaust, intake and compression occur and repeat would be a treat, not to mention the slow movement would make a very cool display.
I would guess a long stroke would be in order, maybe twice the current norm. Also maybe a o-ring to really seal the slow piston?
My question is how slow could a engine like this run do you think? Would this idea even work? From my calcs, 20 rpm would be a power stroke every 6 seconds.. Imagine the sound... 1.5 seconds for the exhaust stroke.
Wouldn't mind building one but is there even a chance it would run?
