ABSTRACT:
An air fuel ratio control system for an internal combustion engine having an electronic engine control module and an upstream and downstream exhaust gas oxygen sensor positioned in the engine exhaust gas stream. A first feedback loop includes the upstream EGO sensor. A second feedback loop includes a downstream EGO sensor and a trim bias signal to bias stored values provided from an air/fuel bias table. Such a biased signal is applied to an air fuel feedback controller which provides a feedback air fuel control signal to be applied to an open loop fuel controller.
