I think the rotor is too narrow. That compromises the rotor bearing
and limits the RPM. There is a proper ratio of width to diameter
for plain oil pressure fed bearings. If this is too narrow the plain
bearing loses load capacity.

I spoke to them about it at AERO in 2009.

I think Dankwart worked for Felix Wankel as a technician.

The interesting thing is that they make claims of compression
ignition/diesel.
Little evidence of actual shipping products, though.

I have never seen one out side of their booth at AERO.

It does have a somewhat higher compression ratio but not enough
to run as a true diesel. It just burns diesel fuel. Any Wankel
will do that.

Wankel Supertec run the Diesel version with a spark plug.

I find the Wankel and Diesel fuel do not really go well together as the
Wankel needs speed for power while Diesel burns relatively slow.

Rolf Pfeiffer

Maybe that is what set back the CW stratified charge as they were mostly
using diesel fuel. Rolf did you know Dankwart Erdman ?

Paul,
Two of us visited Prof. Dr. Ernst Sigmund in Cottbus for a possible licensing deal on behalf of Rotary Revolution and were shown their test facility running a Wankel Diesel.

We had asked for Mr. Dankwart Eiermann and were told that he is not available. Yes, he had been working very closely with Mr. Felix Wankel who, by that time, had long passed way. Dr. Sigmund was very attentive to us. As we all know he also is no longer among us when his brother took over as CEO. I am not sure if he still holds that position.

Here is some info on patents by Mr. Dankwart Eiermann.

He sure has a lot of Wankel patents. Must have had a patent attorney working full time :-)
