Barrie,
Can't add expert knowledge or analysis to the discussion, but as usual
I'm happy to take a guess ;-)
Perhaps there is already combustion going on all the time and the O2
just helps make it a cleaner burn. Is that possible? I sure have seen
flames coming out the back of hot setups. On engines with modern cats,
maybe there is less need to add the O2, since those systems are relying
on catalyst of the bad stuff (technical term).
I have a good engineering book on the topic lying around somewhere that
might tell me...I'll keep an eye out for it.

Subject: Re: Fw: Re; Emssions controls, or their lack of
This subject needs expert analysis. I just cannot believe that the air
pump results in an after burn as this would mean very hot exhaust pipes
and
presumably a noticeable belching out of flames. A simple test to see if
there was any oxygen left in the exhaust of a non-air pumped car would
be a
start. This would mean the air pump was not doing anything more than
adding more air and thus being useless! Anyone got the means to test
exhaust gases? The spontaneous burn-off seems unlikely as there is no
ignition and no compression. If there is unburnt fuel just looking to
go
whosh then what happens when you put a match to the exhaust of a
non-pumped
car. Do you get a burn??? Seems that if you do, putting a spark plug
on
your tail pipe may be fun....Mummy, look at that car go.....
