OT World's Smallest 12 cylinder engine OT

[50 Dodge Lug Nut]

Take a look at this tiny engine. The machining, assembly and detail is extraordinary.

Be sure your speaker volume is up. The music as it builds to a crescendo, adds to the video.

¿dónde están las bujías de encendido. Se trata de un motor diesel?

Frank,

I will never cease to marvel at craftsmanship of that nature. I have a few questions about it, such as its running speed and the torque it produces, but questions are rather trivial after seeing it run. Absolutely amazing. Thanks.

I didn't see any spark plugs? Could it be compressed air is all that's running thru that hose? Also without a cooling system, and a complete lack of oil sump, I would suspect heat from combustion would burn it up quick. me thinks this one is just a machinists folly.

Compressed air.
