Precise air-fuel ratio control Keep the engine mixture close to the theoretical air-fuel ratio for optimized combustion and consistent performance. Real-time feedback through accurate oxygen sensing The oxygen sensor accurately monitors exhaust oxygen content and converts it into a voltage signal for feedback to the engine control unit, enabling the ECU to adjust the air-fuel ratio in real time according to actual working conditions. Enhanced performance and efficiency By maintaining the ideal mixture, the system improves fuel combustion efficiency, supports stronger engine power delivery, and enhances fuel economy. Fast and reliable response Designed for quick response to changing engine load and exhaust conditions, ensuring the air-fuel ratio is continuously optimized. Compatibility and integration Built to work with standard engine management systems and common exhaust configurations, ensuring straightforward integration and reliable operation. Practical use scenarios - Daily driving: improves fuel economy and throttle response in everyday commuting. - Performance tuning: enables precise fuel metering in sport or high-load driving for consistent power output. - Maintenance and diagnostics: validates sensor performance and ECU feedback to ensure proper combustion control.
