lean mixture..results to increase NO2,, increasing the fuel will reduce NO2 but increase carbon monoxide, so the EGR is developed to reduce NO2 without increasing the fuel in turn increasing the CO.
Nitrogen dioxide (NO2) is the oxide of nitrogen produced by forest fires and internal combustion engines. It is a reddish-brown gas that contributes to air pollution and can have harmful effects on human health and the environment.
The main acids which cause rain to become acidic are nitric acid (HNO3) and sulphuric acid (H2SO4). These result from the gases NO2 and SO2 which can result from certain types of combustion in internal combustion engines or in electric power plants that burn coal.

Oxides of nitrogen (NOx) are primarily formed from combustion processes, such as in vehicles and industrial sources. Nitrogen in the air reacts with oxygen at high temperatures inside engines or industrial furnaces to form different oxides of nitrogen, including nitric oxide (NO) and nitrogen dioxide (NO2). Atmospheric nitrogen can also react with lightning or UV radiation to produce NOx.
The brown gas is called nitrogen dioxide (NO2). It is a reddish-brown gas that is a common air pollutant produced by combustion processes.
The equation for the incomplete combustion of hydrogen is 2H₂ + O₂ -> 2H₂O + energy (incomplete combustion).
NOx is shorthand for "oxides of nitrogen", which are largely byproducts of infernal combustion. Inclusive of NO2, N2O, N2O5 and more. Naturally occurring NOx compounds are made high in the atmosphere, in the ozone layer (lower stratosphere), too. Whether or not they remain stable or decay to nitrogen, oxygen and/or ozone depends on how much water vapor is present there. Typically, NOx made up here does also not survive to reach the troposphere, since it is very chemically reactive (much like ozone). At the surface NOx is a product of combustion and can be emitted from internal combustion engines, furnace, boilers and heaters.
Nitrogen-di-oxide popularly known as laughing gas due to its euphoric properties is widely used as an anesthetic and analgesic. It is also used in internal combustion engines and aerosol propellants. However prolonged exposure to NO2 can result in mental dexterity, numbness and audio-visual inability. Also NO2 given to patients with vitamin B12 deficiency can severely affect the nervous system. Usually precautions are taken henceforth. It has also shown to have adverse reproductive effects on pregnant females. However it should also be noted that every year a lot of people die due nitrogen asphyxiation.
NO2 is more harmful to the environment than NO2-.
Nitrogen dioxide (NO2) is made of one nitrogen atom and two oxygen atoms. It is a reddish-brown gas with a sharp odor, and it is a common air pollutant produced by combustion processes from vehicles, power plants, and industrial activities.
Acidic gases causes acid rain. SO2, NO2 are examples for that.
NO2 is the molecular formula for NO2.
