Working principle of NOX sensorThe working principle of the nitrogen-oxygen sensor is based on the REDOX reaction. It contains an electrolyte welded to an ammonia sensor between two electrodes. Under normal working conditions, ammonia reacts with oxygen to form nitrogen oxides. Nitrogen oxides can cause the oxygen electrons to deflect, with one of the electrons flowing toward the electrolyte and causing a current to flow. The sensor''''s circuitry measures the change in current and converts it into nitrogen oxide concentration information. This signal is then transmitted to the ECU to guide the adjustment of the gas mixture during engine combustion to reduce nitrogen oxide emissions.
What does a NOx sensor do?The NOx sensor not only monitors the level of the oxides of nitrogen being released into the air, but it also plays an essential role in controlling it through the Selective Catalytic Reduction (SCR) system in diesel vehicles.
The NOx sensor is a key part of this system, which also includes the SCR catalyst, Diesel Particulate Filter (DPF), and turbocharger amongst others. If the NOx sensor detects too much NOx gases being emitted, it sends that information to the SCR system, which then adjusts the output to a level that’s compliant with emission regulations.
