- Precise control of air-fuel ratio - How it works: The oxygen sensor accurately monitors the oxygen content in the exhaust and converts it into a voltage signal for feedback to the engine control unit. The ECU uses this signal to adjust the air-fuel ratio in real time based on actual operating conditions, ensuring the mixture stays near the theoretical air-fuel ratio and improving fuel combustion efficiency, engine power, and fuel economy. - Quick response Benefits - Real-time, accurate regulation of the air-fuel mixture to optimize combustion - Improved engine power and better fuel economy - Consistent performance across varied driving conditions Key attributes - Function: oxygen sensing with voltage feedback to the engine control unit for air-fuel adjustment - Compatibility: designed to work with engine control units that receive oxygen sensor signals to regulate the air-fuel ratio - Performance: precise control with fast response to changing exhaust composition - Size and material: not specified in the provided description Applications - Regular gasoline engines in passenger cars to enhance efficiency and performance - Engine maintenance or tuning to maintain optimal combustion across driving conditions - Long-distance or mixed driving to sustain stable fuel economy and responsive power delivery
