ABSTRACT:
An A/F detector having an output which is unambiguous over the entire operating region of the device, including both fuel-rich and fuel-lean regions. The detector includes two cells, an electrochemical cell and a pump cell. A constant current is passed through the electrochemical cell and the current through the pump cell is controlled in such a manner that the voltage across the electrochemical cell is constant. The current through the pump cell is detected to provide the unambiguous output signal.
