- Precise control of air-fuel ratio for efficient combustion and improved fuel economy - Real-time feedback loop The oxygen sensor accurately monitors exhaust oxygen content and converts it into a voltage signal that is fed back to the engine control unit. The ECU adjusts the air-fuel ratio in real time to match actual operating conditions, helping the mixture stay close to the theoretical ratio. - Quick response Fast sensor reaction ensures timely adjustments to changes in engine load, temperature, and speed, maintaining optimal performance and efficiency. - Key attributes Function: monitors exhaust oxygen and provides ECU feedback to regulate the air-fuel mix Compatibility: designed for modern gasoline engines with standard oxygen sensor and ECU systems Size: compact sensor suitable for typical exhaust layouts Material/Durability: built to withstand high-temperature exhaust environments for reliable long-term use Performance: high sensitivity, stable voltage signal, contributes to better combustion efficiency, power delivery, and fuel economy - Practical use scenarios 1) Daily urban driving to maximize fuel economy and smooth idle without sacrificing performance 2) Light towing or heavy load driving where maintaining an optimal air-fuel mix improves power delivery and engine efficiency 3) Engine tuning or diagnostics on vehicles with ECU-based fuel management to ensure accurate AFR feedback and consistent results
