BL3A-9Y460-CA Auto Parts Sensor

   The working principle of the oxygen sensor on the car: Under certain conditions, the potential difference is generated by using the oxygen concentration difference between the inside and outside of the zirconia, and the greater the concentration difference, the greater the potential difference. The oxygen content in the atmosphere is 21%. The exhaust gas after the combustion of the rich mixture does not actually contain oxygen. The exhaust gas generated after the combustion of the lean mixture or the exhaust gas caused by the lack of fire contains more oxygen, but it is still higher than that in the atmosphere. Much less oxygen. At high temperature and catalyzed by platinum, negatively charged oxygen ions are adsorbed on the inner and outer surfaces of the zirconia sleeve. Since the oxygen in the atmosphere is more than that in the exhaust gas, the side of the casing connected to the atmosphere adsorbs more negative ions than the exhaust gas side, and the concentration d…
