Why Choose US:

NOx sensor (SNS) used for catalyst management in vehicles with gasoline or diesel engines. The smart NOx sensor consists of a ceramic sensor element and an electronic control unit (ECU). 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) and can be.

Used for

● Lean burn engines (NOx trap)

● Diesel engines (SCR catalysts, NOx trap, closed-loop NOx control)

● On board diagnostics, OBD (gasoline and diesel engines)

The specified mounting position of the NOx Sensor is downstream of NOx trap or upstream or downstream of SCR catalyst. (See also => Built-in-instruction)

NOx Sensor Application Handbook

What is NOx Sensor --- Product Principle

● Exhaust gas which contains H₂O, NO₂, NO and O₂ going through 1^stcavity by molecular diffusion.

● O₂ was decompensated and pumped out at 1^st cavity, NO₂ turn to NO, rest gas go through into 2^ndcavity.

● NO was decompensated into N₂ and O₂ at M₂, NOx concentration was calculated by current accordingly.
