Ok now you got my attention.  Francois  what is this diesel burning
adaption Thomas is talking about?

Doug

I let Francois tell you the details (....as I don't know them :))), but what
I understand is, that Mistral wants to certify a Jet A burning version of
their Rotaries. It is NOT a Diesel engine per definition, as in compression
ignition, but a spark ignited, diesel (or Jet A) direct injected engine.
Just went of the Audi website, looking at their Le Mans Quattro concept.
This engine also uses direct injection, though I guess it is adjusted for
gasoline.

In the past Mistral had problems with fouling sparkplugs (after some 200
hrs), but what the heck, make it a service/inspection point for 100 hrs to
check/clean/change sparkplugs! At least in Europe you will save a set of
sparkplugs on the first tank full off Jet A compared to Avgas!

I believe you could adapt just about any gasoline engine to burn Diesel this
way. All you need is a high pressure injector pump and a place to install
the injector. The rest is dyno runs to adjust the system. With some
computers added it should eve nbe able to burn ANY liquid fuel!

Yes or gaseous fuel.  I think Mazda did some experiments with diesel way
back when.  Now with new research Renesis engine they have direct ports
(look at the 11:00 o'clock position near the front of casing) in the
combustion chamber into which they inject hydrogen gas.

The front view placards show the upper injector to be for hydrogen, the
lower left one for gasoline.  The location for diesel injection ???? Maybe
diesel would benefit from being  prewarmed a little.

BTW. The engine pictured below is a hybrid.  The middle section just in
front of the transmission contains the electric motor.

Check out the electric boost motor sandwiched between the turbine and the
compressor.  This engine is designed for near zero pollution and good
mileage.  Perhaps when fuel cells, batteries and hydrogen storage get and
more compact  we will be calculating range using miles per kW/hrs:)  Until
then our best bet is the rotary.

That looks exactly like the same display Mazda had at the Geneva auto show. Where 
you in Geneva Doug?
