ABSTRACT:
An air-fuel ratio control system for an internal combustion engine supplies a very small sample of the air-fuel mixture being inducted to an air-fuel ratio sensor. A heater heats the sensor and also heats and ignites the air-fuel mixture sample at the sensor. A fuel system control controlled by the sensor then adjusts the air-fuel ratio of the mixture being inducted into the engine to the stoichiometric value.
