• The importance of turbocharged engines: During operation, the intake and combustion pressures of turbocharged engines vary greatly. Oxygen sensors accurately monitor the oxygen content of exhaust gas, helping ECU adjust the boost pressure and fuel injection quantity in a timely manner to prevent engine detonation and improve the reliability and performance of the turbocharging system.
• Characteristics of adapting to different altitude environments: In high-altitude areas, the air is thin and the oxygen content is low. The oxygen sensor can automatically adjust the monitoring benchmark and work with the ECU to recalculate the air-fuel ratio, allowing the engine to operate normally in low oxygen environments, reducing power loss and maintaining vehicle performance stability.
• The impact on engine cold start fuel injection strategy: During cold start, the engine temperature is low and the fuel atomization effect is poor. Although the oxygen sensor has not reached the optimal working temperature, it still provides signals to the ECU to help determine the additional fuel injection amount during cold start, ensuring smooth engine start and reducing start time and fuel waste.
• Characteristics of signal processing circuit: Internally integrated complex signal processing circuit amplifies, filters, and converts the weak oxygen signal obtained by the sensing element into a standard voltage signal suitable for ECU recognition, ensuring the accuracy and stability of signal transmission and reducing external interference.
• Adaptability under different climatic conditions: In high temperature and hot areas, our oxygen sensor can withstand higher environmental temperatures and exhaust pipe high temperature impacts; In humid and rainy areas, it has good waterproof and moisture-proof performance, preventing components from being short circuited due to moisture and ensuring stable operation under various complex climatic conditions.
