mode where you injected it at just the right time to cause ignition
by the red hot exhaust valve.

Mike asks,

So, for me this begs the following question.  Have any of the rotary

crowd

made an attempt at setting up a stock 12a or 13b as a diesel?  I think

it

would be interesting to try.  Maybe that would be a good use for my

$50

13b

core.

Unfortunately the rotor combustion chamber shape does not lend itself to

the

high compression required of a diesel. The RR version used in effect two
Wankels working together to generate the high compression required which
defeated the compact and light weight advantages of the Wankel in the

first

place.

That is not to say it cannot be made to run on diesel fuel however.

So it could be made to run on diesel fuel but not as a diesel (i.e. by
compression) and still need the spark provided by a plug.  Would this

give

any advantage other than potentially cheaper fuel(or just more of an
intellectual exercise)?  Just curious. TIA.

All the best,

Just cheaper fuel. The BSFC is no better.

Cheaper fuel maybe, but more available fuel definitely. With the demise of
avgas eminent, it would be nice to be able to run a rotary off of jet fuel
(kerosene). When operating out of one's home base, most people would use
diesel because self fueling with automotive diesel would be cheap. When
traveling, automotive diesel would rarely be available but jet fuel is
everywhere. I fly out of DVT. We can't buy mogas OR diesel, but we can get
all the jet fuel we want (at a mere $2.85/gal currently). I would be VERY
interested in a rotary that can burn diesel/kerosene. I think it is much
more than an intellectual exercise.
