【NGK OZA684-EJ1 Oxygen Sensor O2 Sensor ngk oza684-ej1】
When porous electrodes are placed on both sides of a zirconia ceramic, with one side exposed to the atmosphere and the other to exhaust gas, an electromotive force is generated according to the oxygen concentration on the exhaust gas side.
This characteristic can be utilized to control the air-fuel ratio of exhaust gas.
