- Precise control of air-fuel ratio to keep the mixture near the theoretical ratio, improving combustion efficiency and overall engine performance. - Real-time closed-loop feedback: the oxygen sensor accurately monitors exhaust oxygen content and converts it to a voltage signal for feedback to the engine control unit, allowing the engine to adjust the air-fuel ratio according to actual operating conditions, thereby enhancing fuel economy and power. - Quick response: fast sensing and adjustment to changing driving conditions and loads. Key benefits - Improves fuel combustion efficiency - Enhances engine power output - Better fuel economy and smoother operation Key attributes - Function: closed-loop air-fuel ratio control using oxygen sensor feedback - Compatibility: designed for use with standard oxygen sensors and engine control units in modern vehicles - Performance: real-time adjustments with rapid response to changing conditions Use scenarios - Daily city driving to maximize fuel efficiency and reduce emissions - Highway cruising and overtaking where consistent mixture improves performance - Towing or carrying heavy loads that require stable fuel mixture and better power delivery
