Abstract: PURPOSE:To stabilize a base line without impairing the life of an alkaline metal salt ingot by disposing an alkaline metal salt in a position apart from a nozzle port, heating this metal salt and moving the vapor thereof to a reaction region by gaseous flow. CONSTITUTION:The alkaline metal salt ingot 10 is housed in a chamber 13 existing below a nozzle ejection port 2 and an air supply port 15 is provided on the rear side of the metal salt ingot 10 of the chamber 13. The discharge port of a column A for, for example, gas chromatograph is connected to the rear end of the nozzle 1 to generate a hydrogen flame and electric power is supplied to a heater wire 11 to generate the vapor from the metal salt ingot 10. The ion of the alkaline metal salt is generated in this way. This ion is entrained in the flow of the gaseous air from the supply port 15 and is carried to the reaction region in the upper part of the ejection port 2. An N or P compd. is heated by a hydrogen flame when the compd. is discharged from the column A. The compd. is then ionized by selectively reacting with the metal salt ion and is carried by the gaseous air, by which the ion is moved to a collector electrode 3. This ion is detected as a change in the electrical conductivity with the ejection port 2.

CONSTITUTION:In the detecting system of air/fuel ratio of an internal combustion engine, exhaust gas flows in an air reservoir 2 surrounded with solid electrolyte 1, and if the air/fuel ratio is lean, the voltage between the electrodes 6a and 6b of electric cell element 8 becomes lower than the voltage Vr1 of the reference voltage supply 12 and the output level of the differential amplifier 11 becomes plus. Then electric current appears from the electrode 5a to 5b in the oxygen pump element 7, which applys voltage on a resistor 15 and inversion input of an operational amplifier 13. If the air/fuel ratio is rich, outputs or electric current in this process are inversed. Therefore, the pump current is always proportional to the oxygen concentration in exhaust gas, so that the voltage appearing on the resistor 15 is A/D converted and processed with a processor 17. Thus, the output of the obtd. detecting device are almost proportional to the oxygen concentration.
