Dear Paul,
What is the current development status of that German Diesel Rotary engine
Could you give some guidance as to it's improvement in
performance;and also
any flight tests it has it been subjected to ?

Thanks.
Dave Young.

I have no new information for the past couple of years.
I am a bit skeptical that it actually works.
I'll believe it when I see it run in something like
a car or airplane.

  Hi, I think you are thinking of heavy fuel versions of Wankels with efi
and spark plugs.  True diesels are compression ignition engines; no spark
plugs. R-R was working on 2 stage compound Wankel diesels, I have seen
drawings but do not know if any ever ran.  There may be some current work?
