Contents.Availability /NGK produce NOx sensors for automotive and truck applications. Several automobile and related companies such as, and have also put extensive research into development of NOx sensors. Many academic and government labs are pushing to develop the sensors as well. The term NOx represents several forms of nitrogen oxides such as NO , NO 2 and N 2O ( aka laughing gas). In a engine NO is the most common form of NOx being around 93% while NO 2 is around 5% and the rest is N 2O. There are other forms of NOx such as N 2O 4 (the of NO 2), which only exists at lower temperatures, and N 2O 5, for example.
However, owing to much higher combustion temperatures due to high cylinder compression and turbo or supercharging, produce much higher engine-out NOx emissions than spark-ignition gasoline engines do. The recent availability of allows the properly equipped diesel engine to emit similar values of NOx at the tailpipe compared to a typical gasoline engine with a. In addition, the diesel oxidation catalyst significantly increases the fraction of NO 2 in ' NOx' by oxidizing over 50% of NO using the excess oxygen in the gases.Motivating factors The drive to develop a NOx sensor comes from environmental factors. NOx gases can cause various problems such as. Many governments around the world have passed laws to limit their emissions (along with other combustion gases such as (oxides of ), CO and CO 2 and ).
Companies have realized that one way of minimizing NOx emissions is to first detect them and then employ some sort of feedback loop in the combustion process, minimizing NOx production by, for example, combustion optimization or regeneration of NOx traps.Difficulties Harsh environment Due to the high temperature of the combustion environment, only certain types of material can operate. The majority of NOx sensors developed have been made out of type metal oxides, with the most common being -stabilized (YSZ), which is currently used in the decades-old. The YSZ is compacted into a dense ceramic and conducts oxygen ions (O 2−) at the high temperatures of a tailpipe such at 400 °C and above.

To get a signal from the sensor a pair of high-temperature electrodes such as noble metals (, or ) or other metal oxides are placed onto the surface and an electrical signal such as the change in voltage or current is measured as a function of NOx concentration.High sensitivity and durability required The levels of NO are around 100–2000 ppm and NO 2 20–200 ppm in a range of 1–10% O 2. The sensor has to be very sensitive to pick up these levels.The main problems that have limited the development of a successful NOx sensor (which are typical of many sensors) are selectivity, sensitivity, stability, reproducibility, response time, limit of detection, and cost.
