Now, if I can just track down the other 3 sets...

Cooling. Or lack of. Yeah! how they kept 4 of these happy on the track is a mystery to me too. Cosmos were blitzing around at the time so its not like MB couldn't crack an L10 open and see How Its Done Right...

Hey, wait..... you can't hoard what you don't have access to, right? Or.... maybe leaving all of those parts in AK was part of your MASTER plan of delayed gratification..... MUHAAAAAA!

In the first pic, the little port at the top of the housing is in the compression area. Was this direct injection?

Thanks for the C111 Hemmings link j_
!
quoted MB engineer in article:
“Our four-rotor engine with gasoline injection represented the optimum of what could be reached with this engine concept."
So it as mechanical fuel injection I think.
Then he went on to whine about the crappy fuel economy:
"Due to the elongated, not exactly compact combustion chambers, fuel economy was poor, resulting in high fuel consumption and unacceptably high pollutant emissions. These drawbacks were inherent in the design principle,” remembers Dr. Kurt Obländer, the head of engine testing for the C111 project.

I understand the last of the C111 cars (there were...4?) was finally used as a test bed for...diesel engines. Oh the ignominy!
