Hello Paul,

John Douglass has asked for informations about the AIE RE (England).
Enclosed you can find 2 pdf files, I have found in 2015. I do not know,
whether they will produce these engines + I don't believe, that the REs will
be as cheap as a 1 rotor Mazda-based one ...

Related to the pumping loss theme I've only found some old japanese papers,
sorry. (1988 / 1990  3x .jpg, 1 pdf ...).

Even older are patents with pumping loss reduction systems by Daimler-Benz -
if you want to see them, let me know ... ;-)

Here are a few datas related to peripheral intake ports by Mazda (1990) ...
 13B with P Intake Port ...
    Intake Runner diameter ...
       a  at open end  60 mm + funnel on top ...
       b  upstream the 90 deg bend  48 mm
       c  at intake port  46 mm
   ~ a
     |
     |b
     .___c

 volumetric efficiency at 7000 rpm over ~ 115% with ...
   intake pipe length 450 mm
    diameter 42 mm

Perhaps you can use the measurements as a "starting point" ...

With kindest regards

We have already determined a length that works. No starting over :-)
Mazda won Le Mans with the length we are using :-)

Side ports. P-ports are over 120% VE and simpler.

AEI is vapor wear until I see it run in a vehicle of some sort.

"Digitally Optimised Lubrication" says nothing.

Is it charged cooled?

Is it a pressure oil system?

What? :-)
