Let’s talk about NOx sensors, how they work, and what happens if they fail. Also, we’ll touch on how they are crucial in cutting down on harmful diesel exhaust emissions.

SAE International Journal of Engines, Vol. 11, No. 4 (2018), pp. 435-446 (12 pages) In a modern diesel aftertreatment system, a sensor for nitrogen oxides (NOx) placed downstream of the selective ...

A practical ZrO2 NOx sensor using dual oxygen pumping cells has been introduced for the control of NOx emitted from a lean-burn gasoline engine and diesel engine. However, the measuring accuracy was ...

Because emissions of PM increase if those of NOx are controlled. It is necessary to control NOx emissions at the regulated limit by using a NOx sensor, thereby minimizing emissions of PM. Therefore, ...

Measuring NOx concentration in exhaust gases of vehicles is essential for emissions monitoring and control. Commercial NOx sensors provide a measure influenced both by the temperature and by the ...
