Lynn,
Love your rants, very educational.

"could we let go of the carburetor and try high pressure direct

Like every damn diesel in the world. If you can't design one yourself,
steal one off of a VW."

I certainly know I can't design one. Do you have any recommendation as

to

which VW system would be a good place to start stealing? I would

really

like to try this in a single rotor test bed.

Fred,
You may want to try to get a hold of Gary at TWM. He really knows his

stuff.

Bought a 3003 with single injectors for my 20bt.  It may not idle the
greatest, but really simplifies many other things.  They have LARGE,
EXPENSIVE  injectors that go up to about 125 per rotor if you want. The
output of the large injectors are definitely interesting.

Very interesting thought.  A Rotary converted to a diesel.  Why not just
mill up a higher compression rotor, slap in two of the VW TDI injection
systems (get the third injector for in cylinder diagnostics), or better yet
the new High Tech VW PD TDI (2004 in the US, 2003 in Europe) systems and
save yourself the high pressure plumbing, and make a single rotor diesel
("Rational heat engine" is the name the designer gave it).  You could use
the TDI Brain.  There is about a dozen small company's hacking the TDI
Computer who could help you get it running.

A 75Hp single rotor diesel, made with off the shelf automotive parts, would
about put rotax out of business I would think.

Very cool

Not that easy.
The problem is the higher the compression ratio the worse the shape of the 
combustion chamber. Ten to one is about the practical limit. If you just
want to burn jet fuel no problem. Go for spark assisted direct injection
but don't expect diesel like BSFC's.
