The function of oxygen sensor
- Nov 20, 2018 -

The function of the sensor is to determine whether there is excess oxygen in the exhaust of the engine after combustion, i.e. the oxygen content, and to convert the oxygen content into a voltage signal to transmit to the engine computer, so that the engine can achieve a closed-loop control with the excess air factor as the objective, and ensure the hydrocarbon synthesis in the exhaust of the ternary catalytic converter. The three pollutants (HC, CO and NOX) have the greatest conversion efficiency, and they can be converted and purified to the greatest extent.
