Oxides of nitrogen, especially as atmospheric pollutants.
（尤指污染大气的）氧化氮
targets to reduce NOx
as modifierNOx emissions
Example sentencesExamples
Pacific Northwest National Laboratory researchers have developed a new cost effective and energy efficient method for reducing oxides of nitrogen, or NOx, in diesel engine emissions.
The harmful effects of NOx and carbon dioxide have not been calculated, but are probably lower than either SO2 or ozone.
They also emit nitrogen oxides, or NOx, a key component of smog.
As my passengers speak knowingly about performance features and NOx traps (nitrogen oxides are a nasty component of most fuel exhaust), I am fixated on the hydrogen sensors.
The system incorporates a catalyst to reduce NOx emissions as well as a particulate filter.
