OPERATIONAL V-12 DIESEL ENGINE THAT FITS IN THE PALM OF YOUR HAND.
This is not CNC technology; this guy made everything at home on his lathe and drill press. Took 1220 hours (a year and a half?) to make the 261 pieces. Note the end-loaded crankshaft into the block (like an Offy), 12 individual cylinder heads, TINY rods and pistons, dual "underhead" cams with pushrods to rockers in the heads. And, he did break-in runs using an electric drill driving the crankshaft!
Even if you're not an engineer, you'll appreciate this!

Wow That must have taken a LOT of patience

Incredible!I wonder how the injection pump works?
I sometimes wonder if these old world craftsmanship skills are being lost in this new age.
-
The test run at the end, was it really running? Only mechanical clatter, no exhaust? Whatever, that thing is completely amazing even if it never gets a drop of fuel in its entire lifetime. I wonder if the guy is a jeweler as a night job?

looks like its running on compressed air. Still very cool.

ir runs as a rc engine, no spark but high compressed nitro rc gas.
that sir is a genious building something that small and so perfect.

Looks like compressed air gets the nod. No oil bath, no piston rings, yada yada. Fuel and combustion would not be a good idea.

+1 there!
