Luke,

Here are some additional SAE articles on the UEGO
(Universal Exhaust Gas Oxygen)  O2 sensors that can sense a
wider range of A/F ratios. The regular heated O2 sensors
that have been used for years can only sense over a very
narrow A/F range.

930388 A feedback A/F control system for low emission
vehicles
920234 Universal air-fuel ratio heated exhaust gas oxygen
sensor and further applications
922172 Steady state wide range air fuel ratio control
940373 Adaptive air-fuel ratio control of a spark ignition
engine
940149 Automatic control of cylinder by cylinder air fuel
mixture using a proportional exhaust gas sensor
