What is the role of oxygen sensors?

Nov 19,2018

The role of the sensor is to determine whether the engine after combustion exhaust oxygen excess information, that is, oxygen content, and the oxygen content converted to voltage signal transmission to the engine computer, so that the engine can achieve the excess air factor as the target of closed-loop control, to ensure that the ternary catalytic converter on the exhaust hydrocarbon (HC), Carbon monoxide (CO) and nitrogen oxides (NOx) three pollutants have the greatest conversion efficiency, the greatest degree of emission of pollutants conversion and purification.
