Dale,
That reminds me that raising the combustion temp  OR  increasing the A/F 
ratio in our Corvair engines both raise the  NOx level in the  exhaust 
significantly.  The high temp can be  solved with water injection  while the 
increeased 
A/F ratio (even  above stoichiometric 14.6:1) is not so easy  to solve.  Of  
course, we could have a SECOND and optional "map" setup in  our fuel  
injection 
program so that when we go for emission inspection the car   runs RICHER than 
stoich.  Reminds me of how I used to manually   "detune" the 140 just before 
I 
took it for the NJ emission test and  then  "retune" it a half hour later in 
the 
company parking lot before  I drove it  home.  But now it can all be done 
automatically by  flicking a switch.   Ain't progress wonderful?

And I thought California was unduly restrictive; here in the home of "smog"  
I don't  (due to the age of my 'Vairs) have to get a smog inspection every  
year to get my registration renewed.  
 I sometimes think (when I'm aroused to the point of insanity) that  I'd like 
to take the noisy environmentalists and smog freaks and visit Auschwitz  (or 
was it Buchenwald) and let them have a whiff of Zyklon B---smells just  peachy 
as long as they can breathe.
