This gargantuan single cylinder engine is the largest known in the world, with a 21 inch bore x 30 inch stroke (displacing approximately 170 liters!). The information and introduction is given by Terry Smith, a longstanding member and tourguide of the Coolspring Power Museum.
Note: this engine is owned by Coolspring Power Museum, and permission was given to record and share Terry's exceptional knowledge.

It would be better if we could get a more detailed view of the engine, instead of just the narrator with the engine in the background.

That’s why you need to go see it for yourself. The displays are awesome.❤ I need to go back.

I did a little online research and quickly came to a dead end. I had to go check Crossley engines. The engine I thought of immediately turned out to be two cylinder horizontal with open crankcase, so it’s not a contender for biggest single cylinder, but with con rods 10 feet long and a estimated weight of 30 tons it’s a beast. Built in 1907. I cannot find what fuel it used, so I’m not even certain it’s a diesel. Last known to be in Argentina 15 years ago.

Check out Henry Ford about his nine single cylinder engines. This machine, 82 feet long, 46 feet wide, and weighing 750 tons, is one of nine that powered the Ford Motor Company's Highland Park plant while Model Ts were being manufactured there. Together, the nine machines generated 53,000 horsepower.

@timmccartney6078 10 ай бұрын

YES it has a 26inch bore and a 38 inch stroke. That should make it bigger.

There are 2 much larger cylinder engines. They are Humphrey Pumps located at Cobdoglah in South Australia. They have bores of over 1 Meter and were used to pump water but are now on display.

Single cylinder Doxford J Engine that was (maybe still is?) at South Shields Marine and Tech back in the mid 80's absolutely dwarfed this engine.

There used to be some very big engines in the Ogema Hills near West Branch Michigan. They ran something related to the oil wells in the hills. I was 20 and climbed all over them so I believe they were bigger and they were spark ignition. It seems like they were Green and said AJAX on them. That was 50 yrs ago. ben/ michigan

Hmm not the largest in the world, only have to look at Kew's 90 inch and 100 inch single cylinder Cornish beams where the beam itself prob weighs more than that whole engine does and the cylinder itself housing the piston on either is much bigger than the whole engine.

I think, what you meant is a steam engine. This engine is gas/ natural gas or diesel powered.

Narration is very good. The half wits that just want to hear it go pop pop pop (chug chug chug) would be happy watching a lawn mower. If you don’t want to hear the technical details just skip ahead. Only suggestion is the camera could have focused in to the engine details a bit more. By-the-way… additionally… the narrator is filling time while the technicians work on getting up and running.
