Product Description
Automobile oxygen sensor is an important sensor in the engine control system, which is mainly used to monitor the oxygen content in the engine exhaust gas and feed back the detected data to the engine control unit (ECU). The oxygen sensor works with other parts to ensure the combustion efficiency and emission performance of the engine.
Firstly, the oxygen sensor senses the oxygen content in the exhaust gas and transmits the detected data to the engine control unit. According to the data fed back by the oxygen sensor, the engine control unit adjusts the fuel injection quantity and ignition timing to maintain the ideal air-fuel ratio and optimize the combustion efficiency.
At the same time, the oxygen sensor also works with the catalytic converter. When the oxygen sensor detects that the oxygen content in the engine exhaust gas is too high or too low, the engine control unit will adjust the fuel supply to ensure the normal operation of the catalytic converter, convert harmful gases into harmless substances and reduce environmental pollution.
In addition, the oxygen sensor also works in conjunction with the vehicle's diagnostic system. When the oxygen sensor fails or is abnormal, the engine control unit will record the fault code and light the fault light of the vehicle to remind the owner to carry out maintenance.
To sum up, the automobile oxygen sensor works with the engine control unit, catalytic converter and diagnostic system to ensure the combustion efficiency and emission performance of the engine and improve the performance and environmental protection of the vehicle. Therefore, it is very important to maintain the normal working state of the oxygen sensor for the safety and environmental protection of the vehicle.
