I thought (and I may be wrong) that the air pump helped with unburnt
hydrocarbons in the exhaust, adding oxygen for complete combustion. The
catalutic converter helps speed up the CO -> CO2 reaction and reduces NOx
(oxides of nitrogen).
Perhaps the Haynes manual says something about this? I don't have mine with me
at the moment...
