Junkers CLM
GRAUBELE:
Hello Roger
The Junkers engine is a very interesting project.
A member of my vintage tractor club has an original Junkers engine that drives a generator.
At operating speed, the engine makes a lot of noise...

It was used there as an emergency generator. But it was only used for maintenance all these years.
My school friend works for the railway himself and got the OK from “above” so that we can remove the engine. The signal box will also soon be demolished and the engine will be scrapped.
The signal box was in the middle of busy tracks and we had to get the individual parts across the tracks as quickly as possible. The whole campaign wasn't really official either 🤫. But everything worked well. (Officially asking the Deutsche Bundesbahn wouldn't have worked, but there were still people on the railway who loved old technology.)
Now the thing is in the old pig sty and there has still been no power outage. The engine starts with one revolution of the hand crank. This is an advantage of the two pistons. The disadvantage: the engine is loud as hell.

Michael S also has a Junkers generator set, it's just as loud :)

A firend of mine has two of these engines, one two cylinder and one single cylinder version. he got them from the Danube shipping doc yard in vienna for free, basically never have been run since they where as a emergency agregat sitting somewhere well stored, dry and maintained. he once asked me, why dont you build a model of this engine instead this old crappy 19th century engine. i said well, there is alsready a guy making one, so i might just wait and watch your build ;D

That's the problem with IC engines and especially two strokes, all the fun bits are enclosed :(
