Tiny engine

Pinched from another forum.
V12 Diesel(?) this time
"AN 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 love this!"

!! But the engine doesn't run, it is driven by compressed air. The engine is for education,exhibitons,etc. so it runs this way to avoid contamination.
