i dunno about how well it works, according to these
people,
"Excess air may be added to the combustion chamber to
get more radical oxygen, O= to oxidize the CO to CO2.
This can reduce the CO to 1% or less. However, this
excess air does NOT reduce total unburned fuel
(pollution), because the extra air inside the
combustion chamber is parasitic and cools the flame.
As the temperature of the flame drops, fewer
hydrocarbons (HC) crack, raising the amount of
unburned HC in the exhaust gases and obviously not
helping to increase miles per gallon. Extra air slows
down the burning process so some of the fuel is
burning to late in the stroke to be beneficial. "

why are there superchargers and turbochargers that
"excess air" to the combustion chamber and produce
prodigous amounts of power?

oh well... my $.02 worth
