Anyone familiar with these beasties? Odd objects, possibly German and
designed around 1949 by a H. Tegen. Fastened to bicycles below the
crank and provided minimal power, a "helper" system. Also seems to
have been a very long stroke twin version that attached to the crank -
two stroke diesel also, abou the same vintage and possibly Heinkel
mfg.

Cheers!

Ah, an overgrown model aeroplane engine.

So I guess that it had a carb, not a bloody tiny injector.

Interesting, though.

A more modern ( but only just ) version of the engine.

That's right... if you can call it a carb. There's no float chamber;
the fuel line plumbs straight into the jet. So I suppose you could call
it an injector in a Wal Phillips stylee, but no, it's not a proper
Diesel injector.
