OK, I get your point.  A few remarks and questions though:

G = Geared
T = Turbocharged  ...or is it TS for Turbo-Supercharged and not
turbo-normalized?
I = Injected
R = Rotary [or radial]  I thought R was for radial.  Is it widely
accepted to be rotary also?

You are new ground there Francois :)

To this list and to be exhaustive, we could possibly add:
L = Liquid-cooled
E(?) =  Electronic control unit  (or is E used for something else?  What
is TCM using for its new FADEC-controlled engines?)

BTW, with this system, our normally aspirated engine would be a GIRL?
:)

My problem with this system is a) if we want to be exhaustive, then our
model designator becomes GTSIELR... a mouthful... and b) MISTRAL engines
will probably never make engines that are not GIEL... all these letters
are fine to differentiate a rotary from a C or a L, but useless to tell
one of our models from another.

Second problem I see:  you propose 80 for 2x40 cu.in.  Fine with me.
But don't we get precisely into the unproductive debate of how to
compare the cubic inches of a rotary with a piston engine?  Shouldn't it
be 160?  Or maybe 240?  From what I recently read on this very
newsletter, even rotary fans cannot agree on the subject!

Then, pilots used to see 360, 470, 540 designators would think ours is a
tiny engine for ultralights!... making our communication job more
complicated.

Third problem:  we hope to offer in the future both a gasoline and a
jet-fuel line of products... and THAT will be a major difference between
our models.  How do we account for that?  In the suffix which nobody but
specialists understand anyway?

I'll appreciate comments very much.

Maybe some sort of designation to imply equivalency so one would know
what displacement it would replace...for example RoI-320E(or EQ)or
RoI-360E-TG?

That is a can of worms I don't think we want to go into.
