【NGK OZA341-EJ2 Oxygen Sensor O2 Sensor 9499 ngk oza341-ej2-9499】
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 in proportion to the oxygen concentration in the exhaust gas.
By utilizing this characteristic, the sensor can be applied to control the air-fuel ratio of exhaust gas.
