     Hello Paul,

     enclosed you can find a Japanese Patent by Mazda + the translation
  (patents.google.com <http://patents.google.com>) as Word 2003 doc.

     It's a description of a modified cooling system with separate
"branches" for
  the hot + cold lobes ...

     The CN ... patent I've found at patents.google.com
<http://patents.google.com>.

     Well, if "Chinese enthusiasts" have developed an oil especially for
Wankel
  engines, perhaps there are plans for production of RE in China ?

     Or will it be for top secret military / defense use only ? Perhaps
somebody
  can give us more informations ... :-)


  With kindest regards

     Franky / Frank Herfert


Mazda may be able to afford the RX9 intro by having the Chinese
make the engine, and possibly other items.

I would hate to see that.
Cessna stumbled badly when they had the Chinese make the Cessna LSA
Apparently you can not get parts for them. Our local FPO has had
one for sale for over a year. No takers.

Hi!: there's an old SAE paper about RCE research in China, 880628, signed by Teluan Chen, I ignore if he's the same Teluan N Chen participating in the Ingersoll-Rand 41 liter per chamber natural gas fueled engine R&D.

Attached are some figures from the Chinese Wankel.

Thanks, have a good season, regards, + Salut

Very interesting if you are building huge low RPM Wankel engines suitable for a 4 TON AKA 8000 pound truck.

The p-port above the normal side port with one way valve helps get more air into the engine
at low RPM to enhance the low RPM torque.


Might work on a car engine but my RX8 can still pull away in first gear with a full load
of four people with out putting my foot on the gas pedal. Then when I press the gas pedal
it will accelerate briskly to 9000 RPM. That is amazing for any car engine.
