Product Description
Introduction
The NOx sensor used for catalyst management in vehicles with gasoline or diesel engines. The NOx sensor consists of a ceramic sensor element and an electronic control unit (ECU). The NOx sensor measures the NOx concentration, air/fuel ratio (A/F ratio) and equilibrium oxygen partial pressure in the exhaust gas of combustion engines (gasoline and diesel).
Features
1.Independent R&D and production of chips
2.Covering multiple series of car models
3.Meet the requirements of stable sensor signals, high accuracy and long service life under various atmosphere environments during vehicle driving

Applications
Petrol Vehicle Emission Monitoring
Cubic automotive oxygen sensors use ceramic sensitive components to monitor automobile exhaust oxygen content in the electronic fuel injection system, and convert the oxygen content into an electrical signal that is transmitted to the ECU, which allows the engine to achieve the target of excess air factor (λ= 1) in a closed-loop; Ensure the maximum conversion efficiency for hydrocarbons (HC), carbon monoxide (CO) and nitrogen oxides (NOx) in the exhaust, and maximum conversion and purification of emission pollutants.
Diesel Vehicle Emission Monitoring
Cubic nitrogen and oxygen sensor is used to detect the content of nitrogen oxides (NOx) in engine exhaust. It is a gas sensor made of solid electrolyte ceramics and nitrogen oxide sensitive electrode materials, using semiconductor technology to detect nitrogen oxides. The nano-composite structure on the surface of the electrode achieves extremely highselectivity of nitrogen oxide molecules. It can be used in the closed-loopcontrol of nitrogen oxides in the SCR system of diesel engines, or in theon-board diagnostics (OBD) of gasoline and diesel engines.
Motorcycle Emission Monitoring
The motorcycle oxygen sensor monitors whether the oxygen content in the engine exhaust is excessive in real time, and converts the detected concentration into a voltage signal, then transmits it to the engine ECU to ensure that the three-way catalytic converter has the maximum conversion efficiency for the three pollutants of hydrocarbons (HC), carbon monoxide (CO) and nitrogen oxides (NOX) in exhaust gas, which can transform and purify the emission pollutants to the greatest extent, and realize the closed-loop control of the engine.
