Method and apparatus for monitoring fluid reductant for internal combustion engine exhaust

A method and means of determining the quality of a fluid reductant used in selective catalytic reduction to reduce NOx emissions from an internal combustion engine. Short and long term average of NOx conversion efficiency are compared with thresholds, in order to determine if failure of selective ca...

Zusammenfassung:	A method and means of determining the quality of a fluid reductant used in selective catalytic reduction to reduce NOx emissions from an internal combustion engine. Short and long term average of NOx conversion efficiency are compared with thresholds, in order to determine if failure of selective catalytic reduction is due to incorrect reductant, or to failure of the catalyst device.
