Core Functions of 0281007432 / 0281007218 NOx Sensor
The 0281007432 0281007218 Nitrogen Oxide Sensor undertakes the critical emission monitoring and system regulation work of the vehicle SCR post-processing system, with three core professional functions that determine vehicle emission compliance and driving stability:
1. High-Precision NOx Concentration Detection
Adopting advanced ceramic solid electrolyte and sensitive electrode sensing technology, the sensor can real-time monitor trace nitrogen oxide content in diesel exhaust with high detection accuracy and fast response speed. It effectively captures subtle changes in exhaust emissions and feeds back accurate data to the vehicle ECU to avoid detection deviation caused by sensor aging or damage.
2. Intelligent SCR System Regulation
Based on the detected NOx concentration data, the ECU automatically adjusts the urea injection rate and atomization effect. This 68214467AA NOx sensor ensures sufficient chemical reaction between urea and exhaust nitrogen oxides, maximizes NOx removal efficiency, and effectively reduces vehicle exhaust pollution to meet Euro VI and North American heavy-duty vehicle emission regulations.
3. Vehicle Fault Warning & Protection
When exhaust emissions exceed the standard or the SCR system works abnormally, the sensor will immediately transmit fault signals to the on-board system, triggering the engine warning light and corresponding fault codes. It prevents vehicle power limitation, startup failure, and forced speed limit faults caused by SCR system anomalies, and protects the engine and post-processing system from secondary damage.
