Product Description:

 
Electronic Oxygen Sensor
OE NO.:   31370195  30651718

Applicable vehicle type: For Volvo
 
 
The automotive oxygen sensor is a critical feedback component of the engine management system. Its core function can be summarized as: real-time monitoring of the oxygen content in exhaust gases, which helps the ECU precisely control the air-fuel ratio, thereby achieving economical, clean, and efficient combustion.
Closed-loop control function
Fuel correction: The ECU dynamically adjusts the fuel injection quantity based on the oxygen sensor signal to maintain the air-fuel ratio near the theoretical value of 14.7:1.
Three-way catalyst protection: Ensures the catalyst operates within the optimal efficiency window (conversion rate above 95%).
Cold start management: Provides open-loop control basis before the engine warms up.
 
Practical Benefits
Fuel Saving: Avoid prolonged rich combustion, saving 5-15% fuel.
Emission Reduction: Reduce emissions of harmful gases such as CO, HC, and NOx.
Performance Optimization: Prevent spark plug carbon buildup and exhaust pipe corrosion.
Fault Diagnosis: Monitor catalyst aging and abnormal engine operation.
