oxides of nitrogen

SCR reduces oxides of nitrogen, the smog precursor known as NOx, by injecting urea periodically into the exhaust system.

In the lower atmosphere the oxides of nitrogen add to an increase in ozone and small particles, which can cause respiratory ailments.

Two pollutants cause most of the problem: oxides of nitrogen, which damage the lungs, and fine particulates, which are also carcinogenic.

Of special concern are the oxides of nitrogen, called NOx; the oxides of sulfur, called SOx; and "particulate matter. "

The oxides of nitrogen, sulfur, and ozone promote UV-induced oxidative damage of common plastics, particularly in rubber products .

The result is a reliable and durable product th at reduces oxides of nitrogen from diesel exhaust, the comp any cl aims.

It will also combine with oxygen to form oxides of nitrogen and when combined with hydrogen in the presence of catalysts, will form ammonia.

At night ozone, a molecule composed of three oxygen atoms, reacts with oxides of nitrogen.
