Air-Fuel Ratio Oxygen Sensor

The automotive oxygen sensor is used to measure the oxygen content in automobile exhaust, and convert the oxygen content into an electrical signal that is transmitted to the ECU, this allows the engine to achieve the target excess air factor (λ= 1) in a closed-loop; Ensure maximum conversion efficiency for hydrocarbons (HC), carbon monoxide (CO) and nitrogen oxides (NOx) in the exhaust, and maximum conversion and purification of emission pollutants.
