“NOx scrubber” refers to an air pollution control device used to reduce or eliminate nitrogen oxide (NOx) emissions from industrial processes, power plants, and other sources. ...
When vehicle emissions first came in focus, most efforts were spent on improving fuel economy, thereby reducing CO2 emissions as well as reducing the levels of carbon monoxide (CO), nitrogen oxides (NOX), and unburnt hydrocarbons (HC), the latter sometimes expressed as total hydrocarbons (THC) or non-methane hydrocarbons (NMHC). ...

Measurement of sulfur components in vehicle emissions is important in evaluating de-sulfating systems for NOx after-treatment systems, such as a lean NOx trap catalyst, where sulfur poisoning on the surface would cause a serious decay of catalyst activity. ...
