Our innovative NOx Sensor is designed to meet the strict requirements of modern emissions control systems. As governments around the world tighten regulations on NOx emissions from engines, the demand for a highly accurate and reliable sensor has soared. This sensor is a key component in helping engines achieve optimal emissions reduction while maintaining efficient operation, providing valuable data for engine management and after-treatment control.
• Advanced Signal Processing: Incorporating sophisticated signal processing algorithms, our NOx Sensor can filter out noise and interference from the exhaust environment. This ensures that the data it provides is clean and accurate, enabling precise control of the engine and after-treatment systems.
• Long - Life Sensing Elements: The sensing elements of the sensor are made from high - quality materials that are designed to last. With a long service life of up to 100,000 hours, the sensor reduces the frequency of replacement, minimizing maintenance costs and downtime.
• Water and Dust Resistance: The sensor is designed to be highly resistant to water and dust ingress. It meets or exceeds international standards for protection against the elements, ensuring reliable operation in various weather conditions and dusty environments.
• Accurate Data for Precise Control: The advanced signal processing technology ensures that the sensor provides accurate and reliable NOx concentration data. This allows the engine control system to make precise adjustments to reduce NOx emissions, optimizing the performance of the after-treatment system.
• Cost - Savings in the Long Run: The long - life sensing elements mean that the sensor requires less frequent replacement. This not only saves on the cost of replacement parts but also reduces the labor costs associated with sensor installation and maintenance.
• Reliability in Diverse Environments: The water and dust resistance of the sensor makes it suitable for use in a wide range of applications, from urban vehicles to off - road machinery. It can operate reliably in different climates and environments, ensuring continuous emissions control.
• City Buses: In urban public transportation, city buses are a major source of emissions. Our NOx Sensor helps these buses meet strict emissions standards in city centers, improving air quality for passengers and urban residents.
• Off - Road Construction Vehicles: Construction vehicles operating on rough terrain and in dusty conditions can benefit from our water - and dust - resistant NOx Sensor. It ensures accurate NOx measurement and emissions control, even in the most challenging environments.
• Emergency Vehicles: Ambulances, fire trucks, and police cars need reliable emissions control systems. Our NOx Sensor provides the necessary accuracy and reliability to keep these essential vehicles compliant with emissions regulations while they are on duty.
Exhaust Emission: Diesel engines produce exhaust gas containing NOx after combustion.
Urea Injection: A urea solution is precisely injected into the exhaust pipe by a metering pump, where it decomposes into ammonia gas (NH₃) at high temperatures.
Catalytic Reaction: Ammonia gas reacts with NOx on the surface of the catalyst (e.g., V₂O₅-TiO₂) in a reduction reaction, producing harmless N₂ and H₂O.
Real-Time Monitoring: The NOx sensor detects the NOx concentration in the treated exhaust gas and feeds the data back to the ECU (Electronic Control Unit), which dynamically adjusts the urea injection amount.
Core Functions of the NOx Sensor:
Based on the solid electrolyte type and the Nernst concentration cell principle, it measures the concentration difference between oxygen and NOx in the exhaust gas, outputting corresponding electrical signals to separately measure oxygen concentration and NOx concentration.
Ensures that the SCR system achieves an NOx conversion efficiency of 80%-97% within the temperature range of 200-400°C.
