This picture is being kicked around a motorcycling forum that I’m a member of, and someone has suggested it may be some type of aero engine.
All I know is that the picture appears to be east European in origin. Looks like a six-cylinder job, with five visible con rods and the sixth second from rear with just the big end visible. Possibly a V-6, as the big end near the camera appears to be forked, so maybe two con rods on one crankpin. Also, it appears to have used cylinder liners, so maybe an alloy block?
Thinking caps on, then – and bear in mind it may not be an aero engine at all![ATTACH=CONFIG]242796[/ATTACH]

As with most of this stuff, Google is your friend!

Well, I’ve learned something today; I’d always assumed that the Jumo 210 had the same 150mm bore of the Jumo 211 and the Jumo 213.

If the information I viewed is correct the early (pre-WW2) Jumo had a displacement of less than 20 litres and the later, larger bore version, around 35 litres.
However, production of the smaller engine ended just before WW2 so the wreck is unlikely to be a 210.

Googling the Jumo gives a bore of 124mm for the early (210) version and 150mm for the later (211-on) versions, if anyone can attempt a measurement from the remains of the liner, it might help to pin it down.
Is a Jumo 210 really only 124mm bore; that sounds a bit small to me?

Brilliant! Thanks for the help and knowledge…I’ve now had to explain to various people that no, I didn’t solve the mystery, but I did know where there were people who could :eagerness:
Thanks once again.

Definitely a dead aero engine. If it is examined closely it will be found to be an inverted V-12 which has hit the ground hard or been blown up on the ground – or possibly both.
The crank counterweights look familiar; I concur with the above posters on Junkers Jumo.
Several candidates for aircraft type but likely Stuka or Ju 88. Assuming Eastern Europe probably a victim of the ill-fated Russian campaign, though the Jumo was used in/over the entire European continent during WW2.

Pretty sure it is a Jumo 211, statistically that is most likely anyway, but I can’t see anything that absolutely confirms that in the photograph.
There were, at least, two distinct designs of connecting-rod for the Jumo 211. Side-by-side they are easy to tell apart; the later design being a considerably ‘beefed-up’ version of the earlier design. The webs and little-end are thicker; it is difficult to tell from your photograph…
…but I’m pretty sure this Jumo 211 is the earlier design.

yes concur a Jumo

Junkers Jumo 211 or 213…..or part of one! 🙂
