Abstract

PURPOSE: To give sensitive response to the oxygen sensor element lacking in the response to the change in concentration of harmful component in exhaust gas resulted from the mounting in car for a long time, by means of immersing it in specific water solution.
CONSTITUTION: The chelate agent such as EDTA which can produce acid such as nitric acid enable to solve lead phosphate and tartaric acid, lead and water soluble chelate compound, is solved in water. The tip 4 constituting the exhaust gas exposed electrode of the oxygen sensor 1 consisting of the solid electrolytic substance surrounding the reference oxygen partial pressure giving means is immersed in the said solution 5, and it is fitted to the upper part of the bath 3 with the sensor fastener 2. It is desirable that the solution 5 is mixed or circulated while being immersed.
