Everything about Exhaust Gas totally explained
Exhaust gas is
flue gas which occurs as a result of the
combustion of fuels such as
natural gas,
gasoline/petrol,
diesel,
fuel oil or
coal. It is discharged into the atmosphere through an
exhaust pipe or
flue gas stack.
Composition
Although the largest part of most combustion gases is relatively harmless
nitrogen (N
2), water vapor (H
2O) (except with pure-carbon fuels), and
carbon dioxide (CO
2) (except with hydrogen as fuel), a relatively small part of it's undesirable noxious or toxic substances, such as
carbon monoxide (CO),
hydrocarbons,
nitrogen oxides (NO
x), partly unburnt fuel, and
particulate matter.
Types
Spark-ignition engines
Main article: Automobile emissions control
Exhaust gas from an internal combustion engine whose fuel includes
nitromethane, contains
nitric acid vapour, which when inhaled causes a muscular reaction making it impossible to breathe, and people exposed to it should wear a
gasmask.

Diesel engines
Diesel Particulate Matter is the main article about diesel exhaust.
Here, conditions in the engine are different from in a spark-ignition engine, because power is controlled by controlling the fuel supply directly, not by controlling the air supply. As a result, when the engine is running at low power, there's enough oxygen present to burn the fuel, and diesel engines only make significant amounts of
carbon monoxide when running under load.

Steam engines
In steam engine terminology the exhaust is steam that's now so low in pressure that it no longer can to do useful work.

Pollution reduction
Emission standards focus on reducing pollutants contained in the exhaust gases from vehicles as well as from industrial flue gas stacks and other air pollution exhaust sources in various large-scale industrial facilities such as petroleum refineries, natural gas processing plants, petrochemical plants and chemical production plants.
One of the advantages claimed for advanced steam technology engines is that that they produce smaller quantities of toxic pollutants (for example oxides of nitrogen) than petrol and diesel engines of the same power. However, there's a downside – they produce larger quantities of carbon dioxide.
