Dear Mr. Lamar:

Happy New Year!  I hope this e-mail finds you and yours very happy indeed!

I found something that may help acceptance of the Wankel rotary engine,
especially when it is operating in its most efficient, leaned-out (and
turbocompounded! :-) mode.

*PremAir radiators*

"http://www.catalysts.basf.com/Main/mobile_emissions/mobile_sources/automotive_emissions/premair_catalysts/using_passenger_cars_to_destroy_ozone.be

"PremAir can be applied to surfaces that come into contact with large
quantities of air to form an effective and durable system for ozone
reduction. Mobile applications include radiators on cars, trucks and
buses. Tests have shown that the catalyst can destroy up to 80% of ozone
in the air passing over PremAir-coated surfaces. Extensive laboratory
and on-road testing also have demonstrated the effectiveness and
durability of PremAir on vehicles.

"Both, the U.S. Environmental Protection Agency (EPA) and the California
Air Resources Board (CARB) have enacted rules that allow automotive
manufacturers who use PremAir to apply for credits under Low Emission
Vehicle programs."

So, until we can overturn wrong-headed emissions regulations, we could
use PremAir radiators to get around the facgt that Wankel rotary
engines, when properly leaned out, exhaust higher-than-piston-engine
levels of oxides of nitrogen (NOx).  We lean out the engine and use the
PremAir radiators as "NOx credits" (a hateful sham, but necessary) to
get governmental approval for our Wankels to run in the necessary range
of exhaust that makes it most efficient.

This will not only help automotive Wankel engines, but also aircraft
Wankels, as the FAA is, seemingly, on an irresistable march to
eliminating 100LL as a piston-engine fuel.

What do you think?

Wishing you a great 2011,

Good hearing from you Les. Merry Christmas and Happy new year.

Latest word from Mazda is the rotary has demonstrated higher
efficeincy than the piston engines Mazda make.
