Why are there two sensors on the car: front oxygen and rear oxygen?
The main reason for separating front oxygen sensors and rear oxygen sensors in automobiles is to improve the accuracy and efficiency of emission control.
Front oxygen sensors are installed in the car's exhaust system close to the engine to monitor oxygen concentration during fuel combustion. The ECU (Engine Control Unit) uses data from the front Oxygen Sensor to adjust the supply of the mixture to ensure the efficiency of fuel combustion and reduce harmful emissions.
The rear oxygen sensor is installed at the rear of the car's exhaust system and is used to monitor the oxygen concentration of the exhaust gases after exhaust gases. In this way, the ECU can detect and diagnose problems in the emission system, such as whether the exhaust aftertreatment device is working properly, by comparing the data from the front and rear oxygen sensors. The post-oxygen sensor can also monitor and control the operation of the three-way catalytic converter to reduce the emission of harmful substances such as nitrogen oxides (NOx) and carbon monoxide (CO).
Therefore, two oxygen sensors in front and rear can enable the ECU to more accurately control the fuel supply and emission control of the car, thereby improving the fuel economy and environmental performance of the car.
