Catalytic converters cannot effectively burn off exhaust gases if the engine air-to-fuel ratio is either too rich or too lean. It is therefore necessary to control automobile engines to run at the stoichiometric point; that is, the air-to-fuel ratio at which all combustible gases can be burnt, leaving no oxygen at the end of the process.
