• Precise monitoring, reliable data: Equipped with advanced wide-area oxygen sensor, it can keenly sense the exhaust gas oxygen concentration and accurately calculate the air-fuel ratio. Whether the engine is idling, driving slowly in the city, or galloping at high speed or accelerating ly, it can give accurate data stably, ensuring that the engine combustion state is clear at a glance, and building a solid foundation for optimizing combustion and improving performance.
• Durable and stable operation: The instrument housing is made of high-strength engineering plastics, which is impact- and -, and can carry high temperature, vibration and oil pollution in the engine compartment. The internal circuit is optimized for anti-interference, and with high-quality sensors, it can work stably in extreme environments and provide long-term stable monitoring, which is worry- and reliable.
• Wide range of adaptability, worry- installation: Adaptable to all kinds of automobile, motorcycle and industrial engines, without fear of differences in car . The installation interface fits the common specifications, according to the instructions, connecting the sensor and instrument wiring, fixing the position, a few steps to complete the installation, easy to start the accurate monitoring of air-fuel ratio, no need to worry about the problem of adaptation.
• Fuel saving and cost reduction: Accurate air-fuel ratio feedback helps the engine to inject fuel accurately. Avoid excessive waste of fuel, eliminate excessive air resulting in poor combustion, long-term use, fuel consumption is significantly reduced, and gas expenses are reduced. It can also reduce carbon deposits, reduce engine maintenance frequency, and reduce the overall cost of the car straight down.
• Enhanced power, driving with ease: help the engine to maintain the ideal air-fuel ratio, to achieve efficient combustion, so that the fuel energy is fully converted. Stronger engine power output, acceleration response, climbing, overtaking in one go, adding more passion and pleasure for driving, releasing the potential performance of the engine.
