What does the Sensor do?

Purpose of Nitrogen Oxygen Sensor:

• Closed loop control of NOx post-treatment system is carried out to improve NOx conversion efficiency and implement more stringent NOx limit standard

• Facilitate the mandatory implementation of OBD from light vehicles to heavy vehicles

• It is an effective and reliable technical means to detect, diagnose and control the NOx emission of diesel engine

Purpose of PM Sensor:

• The content of soot (carbon particles) in the tail gas of post-treatment is monitored.

Purpose of Oxygen Sensor:

• The air-fuel ratio of exhaust gas combustion is controlled to achieve the best exhaust purification effect
