Up to the Experts
Up to the Professionals.
Another interesting engine, thank you Sichel.
A 3 cylinder 2 stroke?
Yes, it is a 3 cylinder 2stroke-engine.
German engine?
Yes.
3-cylinder 2-stroke - is it anything to do with Auto-Union / DKW? (the history of the two is so intertwined that it is impossible to separate them)
No, it was a completely different company.
Does a Master have an idea?
Was it built before 1930 ?
Yes.
Built before 1915 ?
Bolle & Fiedler?
:thumbsup:
Yes, Bolle & Fiedler. Locked for Wendax to answer the remaining question.
Dear 'sichel', please excuse my far too early reply. Thought the puzzle has been solved, after 'Wendax' found the manufacturer. I hope such mishaps don't happen to me again
Max Georg Fiedler designed several two-stroke engines for Bolle & Fiedler. The first three-cylinder engine developed 24 PS out of 1026 cc. Bolle & Fiedler probably also built the three-cylinder two-stroke engine for E. Rosineck (Erco, Eos) which was a 20 PS 1086 cc one. After 1925 Bolle & Fiedler built boat engines like the one on fromwien's post.
We've had a Bolle & Fiedler car before: https://www.autopuzzles.com/forum/new-board/pn-1389/
Yes, it is the 24 hp engine with 1026 cc, installed in the 1923 sports car, see: https://www.autopuzzles.com/forum/new-board/pn-1389/
One more point for Wendax.
