  2. Nitrogen oxide sensor - Wikipedia

    en.wikipedia.org/wiki/Nitrogen_oxide_sensor

    The term NO x represents several forms of nitrogen oxides such as NO (nitric oxide), NO 2 (nitrogen dioxide) and N 2 O (nitrous oxide, also known as laughing gas).In a gasoline engine, NO is the most common form of NO x at around 93%, while NO 2 is around 5% and the rest is N 2 O.

    en.wikipedia.org/wiki/Nondispersive_infrared_sensor

    A nondispersive infrared sensor (or NDIR sensor) is a simple spectroscopic sensor often used as a gas detector.It is non-dispersive in the fact that no dispersive element (e.g a prism or diffraction grating as is often present in other spectrometers) is used to separate out (like a monochromator) the broadband light into a narrow spectrum suitable for gas sensing.

    en.wikipedia.org/wiki/Nitrogen_oxide

    NO y (or NOy) refers to the sum of NO x and all oxidized atmospheric odd-nitrogen species (e.g. the sum of NO x, HNO 3, HNO 2, etc.) NO z (or NOz) = NO y − NO x; Mixed Oxides of Nitrogen ("MON"): solutions of nitric oxide in dinitrogen tetroxide/nitrogen dioxide.

    en.wikipedia.org/wiki/LO-NOx_burner

    It is well established that conventional "blue flame" or bunsen gas burners produce oxides of nitrogen at levels of 30-50 nanograms per joule [5] [6] and are as such not considered to have potential for NO x reduction. Surface combustion burners or radiant tile burners in comparison produce nitrogen oxides' levels 60-70% less. [6]

  9. Nitric oxide - Wikipedia

    en.wikipedia.org/wiki/Nitric_oxide

    Since the heat of formation of • NO is endothermic, NO can be decomposed to the elements. Catalytic converters in cars exploit this reaction: 2 • NO → O 2 + N 2. When exposed to oxygen, nitric oxide converts into nitrogen dioxide: 2 • NO + O 2 → 2 • NO 2. This reaction is thought to occur via the intermediates ONOO • and the red ...
