DAF & Mercedes:

(DAF - 5WK96619D) & (Mercedes - 5WK97331A)


  • 5WK96619D (DAF) & 5WK97331A (Mercedes) are two new Nitrogen Oxide Sensors (NOx Sensors) that have arrived to the FGH stock. The introduction of NOx Sensors (2001) were meant to lower the rate of emissions released from vehicles, as the high rate of emissions was found to be harming the environment. Located in the SCR (Selective Catalytic Reduction) catalyst, the sensor gathers data of the volume of Oxides of Nitrogen that is being produced.

  • NOx Sensor - The NOx sensor is part of the NOx reduction aftertreatment system used in diesel vehicles with urea based SCR systems (Selective Catalytic Reduction systems). With the sensor being located upstream of the SCR catalyst, it directly measures the engine-out NOx gas concentration, which helps determine the optimum amount of urea injection. NOx sensors are produced to help save the environment. Many NOx sensors work by first removing oxygen and then breaking down the nitrogen oxides to provide a reading. The quicker the sensor can detect the Nitrogen Oxide levels, the faster the sensor can get the information to the SCR system; and therefore it can adjust itself and reduce the NOx levels.
  • Nitrogen Oxide Sensors (NOx Sensor) are typically a high-temperature sensor built to detect high levels of nitrogen oxides within exhaust emissions of an automotive vehicle. Sensing the gases is only half of the process, the reason these devices are in place is to trigger re-processing, or loop back systems, within the vehicle is high levels are found, commonly referred to as combustion optimization or regeneration of NOx traps. Many governments around the world have passed laws to limit NOx emissions (along with other combustion gases such as SOx (oxides of sulfur), CO (carbon monoxide) and CO2 (carbon dioxide) and hydrocarbons), so these types of sensors and gas monitoring devices will become increasingly common throughout the industry.
