Hello Paul,

yeah - that's what we wonna see - the rotary in action ;-) Super !

Because the "language of patents" "wears one down" after a few pages,
here's a text, that is much easier to read. It's not specially for
REs, but I hope, it will be of some interest even though ... (I do
not know the company "JCM")

Keep on flying ;-)

With kindest regards

To apply this paper to rotary engines use 45 deg ATDC for the peak
pressure instead of 15 deg ATDC for piston engines. Notice also that
there is no counter pressure built before TDC.  See attached Barry
Bordes


Thanks Barry. Refresh me on the software and pressure sensor you
use. I could install one on the time to climb engine.

Paul,
It is an Optrand sensor and a TFX system.
It would be interesting to identify the proper timing for
methanol fuel to obtain 45 deg ATDC.
Barry Bordes


As I recall the Motec is changing the timing quite a bit as the RPM and
the boost changes. I'll see if I can capture that data.
