Title: Worlds tiniest V12
Post by: TMKIWI on June 05, 2012, 05:46:35 AM
 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!

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

+1 there!
