Scania is a leading global manufacturer of heavy-duty trucks, buses, and engines. In their diesel engines, Scania uses NOx (Nitrogen Oxides) sensors to monitor and control the emissions of harmful nitrogen oxides. These sensors are essential for meeting strict emission regulations and ensuring optimal engine performance.

The main function of the Scania NOx sensor is to measure the concentration of nitrogen oxides in the exhaust gases. It is a key component of the Selective Catalytic Reduction (SCR) system, which reduces NOx emissions by injecting a urea-based solution (Diesel Exhaust Fluid or DEF) into the exhaust stream. The NOx sensor provides real-time data on NOx levels to the engine control unit (ECU), allowing it to adjust the amount of DEF injected to achieve the desired reduction in NOx emissions.

Scania Original Equipment (OE) NOx sensors are designed and manufactured to meet the specific requirements of Scania engines. These sensors are built to provide accurate and reliable measurements, ensuring optimal engine performance and compliance with emission regulations.

In summary, the main functions of the Scania NOx sensor are:

  1. Measure the concentration of NOx in the exhaust gases.
  2. Provide real-time data to the ECU for optimal DEF injection.
  3. Ensure compliance with strict emission regulations.
  4. Maintain optimal engine performance.
