Gases created when nitrogen and oxygen combine in the combustion chamber.
primarily nitric oxide (NO), which in the presence of air, sunlight and hydrocarbons in air pollutants, oxidizes rapidly to form nitrogen dioxide (NO2).
Air emissions produced during the high temperature combustion of all fossil fuels. Oxides of nitrogen are chemically identified as NO, NO2 and NO3 or generically as NOx. In addition to contributing to ozone formation, some nitrogen oxides, such as NO2, are corrosive, acid rain precursors, and can cause respiratory problems. Act 141, Section 10r(3), requires all Michigan electric suppliers, beginning January 1, 2002, to disclose to customers the environmental characteristics of the average fuel mix used to produce the electricity products purchased by the customers. This disclosure will include the average air emissions, in pounds per megawatt-hour, of sulfur dioxide, carbon dioxide, and oxides of nitrogen.
Nitrogen oxide and nitrogen dioxide, together referred to as NOx. Same as nitrogen oxides. Introduction Task Process Information resources Guidance Dr. Bravo Ms. Alarcón Dr. Sosa Dr. Soto Mr. Sanchez
A general term pertaining to compounds of nitric oxide (NO), nitrogen dioxide (NO2), and other oxides of nitrogen. Nitrogen oxides are typically created during combustion processes, and are major contributors to smog formation and acid deposition. NO2 is a criteria air pollutant, and may result in numerous adverse health effects.
Oxides of Nitrogen (NOx) emissions occur when fuels are burned at high temperature. Some of the nitrogen (N2) in the air combines with some of the oxygen (O2) in the air to form nitric oxide (NO). In an engine, some of the NO undergoes additional reactions and turns into nitrogen dioxide (NO2). The emissions of NO and NO2 are collectively referred to as NOx. In addition to contributing to the formation of ozone, NOx emissions also lead to a build up of nitrogen dioxide levels in the atmosphere, which are known to increase the risk of respiratory disease in children. See also Causes of Excess Oxides of Nitrogen.
nitrogen and oxygen compounds that react with the moisture in the respiratory tract to produce acids that corrode and irritate tissue. Chronic exposures to low levels can cause irritation, cough, headache, and tooth corrosion. Examples are NO, N2O, and NO2.
Chemical compounds of nitrogen produced as a byproduct of combustion. They combine with hydrocarbons to produce smog.
Regulated air pollutants, primarily NO and NO2 but including other substances in minute concentrations. Under the high pressure and temperature conditions in an engine, nitrogen and oxygen atoms in the air react to form various NOx. Like hydrocarbons, NOx are precursors to the formation of smog.
a general term for compounds of nitrogen oxide, nitrogen dioxide and other nitrogen oxides. These compounds are typically created during the combustion process and are major contributors to smog formation and acid deposition.
Harmful, gaseous emissions of an engine composed of compounds of nitrogen and varying amounts of oxygen which are formed at the highest temperatures of combustion.
