Why You Should Get a NOx Sensor for Your Diesel Vehicle
NOx sensors are no longer just a feature in racing games like “Need for Speed.” With modern advancements in automotive exhaust systems, these sensors have become a legal necessity to meet environmental standards.
The Importance of NOx Sensors
Globally, there are stricter regulations aimed at reducing pollution, and a NOx sensor is crucial in helping your vehicle comply. Continue reading to understand the role and importance of a NOx sensor in your diesel vehicle.
What is a NOx Sensor?
A NOx sensor measures the levels of nitrogen oxides emitted by your vehicle’s exhaust system. It’s a key component of the NOx reduction after-treatment system, designed to significantly lower harmful emissions. This system typically includes a turbocharger, an SCR catalyst, and a DPF, with the NOx sensor positioned upstream of the catalyst.
How Does a NOx Sensor Work?
NOx sensors analyze vehicle emissions to measure nitrogen oxide levels. They operate using an electro-catalytic mechanism where a specialized material reacts with the nitrogen oxide. By passing a voltage through an electrolyte, the sensor determines the NOx concentration. This data is then sent to the SCR system, which adjusts emissions to meet regulatory standards.
Why You Need a NOx Sensor
Beyond legal requirements to limit pollutant emissions, having a functional NOx sensor is crucial for passing annual emissions tests for diesel vehicles. Failing these tests could result in the inability to renew your vehicle’s license in some regions unless NOx emissions are reduced.
