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 ...

One of the common causes of lost power and performance in diesel-powered vehicles is a malfunctioning nitrogen oxides (NOx) sensor. These sensors monitor NOx levels in the vehicle’s exhaust. If they ...

ABSTRACT Nitrogen oxide (NOx) sensing is required both for on-board diagnosis and optimal selective catalytic reduction (SCR)-catalyst control in heavy duty diesel engines. This can be accomplished ...
