A Cummins NOx sensor is a type of sensor that is used to measure the amount of nitrogen oxides (NOx) in the exhaust of a diesel engine. NOx is a harmful pollutant that can contribute to smog and acid rain. Cummins NOx sensors are used to help reduce the amount of NOx that is emitted from diesel engines.

Cummins NOx sensors work by measuring the electrical resistance of a sensor element. The sensor element is made of a material that is sensitive to NOx. When NOx is present in the exhaust, it reacts with the sensor element, which changes the electrical resistance of the element. The change in electrical resistance is then converted into a voltage signal, which is sent to the engine’s computer.

The engine’s computer uses the voltage signal from the NOx sensor to adjust the fuel injection and air-fuel ratio. This helps to reduce the amount of NOx that is emitted from the engine.

Cummins NOx sensors are an important part of diesel emissions control systems. They help to reduce the amount of NOx that is emitted from diesel engines, which helps to improve air quality.

Here are some of the benefits of using Cummins NOx sensors:

  • They can help to reduce the amount of NOx that is emitted from diesel engines.
  • They can help to improve air quality.
  • They can help to meet government emissions regulations.
  • They can help to extend the life of the engine.
