Oxygen and Nitrogen from the air react at engine temperature. This makes nitrogen monoxide which, when it is released into the atmosphere reacts with more oxygen in the air to form nitrogen dioxide :)

∙ 14y agoNOx is present in exhaust fumes simply because of all ingredients in Earth's air, Nitrogen is the most abundant, therefore it is contained within an engine's cylinder during combustion.
Nitrogen is inert at ambient pressures and temperatures, however when exposed to cylinder heat and pressure, oxides of nitrogen are released, such as: nitric oxide (NO), nitrogen dioxide (NO2), and nitrous oxide (N20).
Unfortunately NOx is a major contributor to photochemical smog because it reacts with hydrocarbons to form ozone molecules.

∙ 12y agoVehicles also need air to burn the fuels they use. Air is about 79% nitrogen. The nitrogen will combust to form nitrogen oxides:
N2(g) + 2O2(g) ---> 2NO2

How is nitrogen oxides involve in the formation of sulfuric acid in the atmosphere?
Sulfur oxides from the combustion of sulfur containing fuels for atmospheric sulfurous and sulfuric acid. Nitrogen oxides form nitrous and nitric acids.
What happen when nitrogen react with oxygen?
There are a number of possible outcomes: some of the resulting compounds are stable, others are very reactive. Common oxides of nitrogen are pollutants that are created in combustion of fuels. See link for details about oxides of nitrogen.
When fuels such as coal and gas are burned what do they release?
Carbon dioxide and possibly oxides of sulphur, hydrogen and nitrogen.
What is a colorless reactive gas is produced when fuels such as coal oil are burned?
It depends on your meaning of reactive:Carbon dioxide gas, which is responsible for global warming and climate change.Carbon dioxide also dissolves in water reacting to produce carbonic acidCarbon monoxide is produced at low levels and can be burned, a classic meaning of reactiveWater vapour is produced which reacts with oxides of nitrogen and sulfur to produce acid rain
What is made when a fuel is burnt?
It would depend on the fuel and whether combustion is complete or not. For typical hydrocarbon fuels (e.g., natural gas, propane, gasoline, etc.) the products of complete combustion are carbon dioxide (CO2) and water (H2O).However, if combustion is not complete, carbon monoxide (CO) and hydrogen (H2) will also be produced. In addition, depending on the fuel (whether it has sulfur or not), oxides of sulfur (SOx) may be produced. Finally, oxides of nitrogen (NOx) are also usually produced, particularly in vehicle engines.
What is needed for nitrogen oxides to be produced when hydrocarbon fuels are burned?
very high temperatures
How is nitrogen oxides involve in the formation of sulfuric acid in the atmosphere?
Sulfur oxides from the combustion of sulfur containing fuels for atmospheric sulfurous and sulfuric acid. Nitrogen oxides form nitrous and nitric acids.
What is formed when nitrogen combines with oxygen when burning fossil fuels?
Various nitric oxides are formed.
What happen when nitrogen react with oxygen?
There are a number of possible outcomes: some of the resulting compounds are stable, others are very reactive. Common oxides of nitrogen are pollutants that are created in combustion of fuels. See link for details about oxides of nitrogen.
When fuels such as coal and gas are burned what do they release?
Carbon dioxide and possibly oxides of sulphur, hydrogen and nitrogen.
What substances responsible for acid precipitation are released into the atmosphere from burning fossil fuels?
Oxides of nitrogen and sulphur.
Are dust particles a cause of acid rain?
No. Acid rain is the result of nitrogen oxides and sulfur oxides put into the atmosphere by volcanoes and the burning of fossil fuels.
What human activities relase sulphur dioxide carbon monoxide and oxides of nitrogen to the atmosphere?
Burning of fossil fuels
How can humans help reduce the problem of nitrogen dioxide?
A power plant using fossil fuels must recover nitrogen, sulfur oxides and in the future carbon dioxide.
The primary products of complete combustion of fossil fuels are?
The primary products of the complete combustion of fossil fuels is: CARBON DIOXIDE and WATER.=)
What are the pros for a nuclear power plant?
It operates without producing the combustion products that fossil fuels do, such as CO2 and oxides of sulfur and nitrogen.
What process releases carbon into the atmosphere from fossil fuels?
Combustion. Fossil fuels contain carbon, hydrogen, Nitrogen, Oxygen and some other elements. But the largest is Carbon. So when such fuels burn they combine with the Oxygen and Nitrogen in air to form Carbon dioxide, Nitrogen oxides etc. Any form of carbon when burns produces carbon dioxide.
