Pollutants from combustion
Carbon dioxide
Why it is formed?
Oxygen from the air passes through the engine to react with hydrocarbons to form CO2 and water.
CO2 is only formed if there is enough O2
Effects
Increased extreme weather
Global warming
Ice caps melt
Sea levels rise
Carbon monoxide
Effects
This results in less oxygen around the body which can lead to oxygen deprivation
High concentrations of CO can be fatal
Can bind to haemoglobin in the blood before oxygen can
Its poisonous
Why it is formed?
When fuel is burned with a lack of oxygen
Leads to incomplete combustion which results in CO
Particulates
Effects
Smog
Global warming
Coats buildings so they look dirty
Why is it formed?
Imcomplete combustion due to a lack of oxygen in the air
Unburnt hydrocarbons
Effetcs
Global warming
Particulates
Oxides of carbon, nitrogen and sulfur
Why is it formed?
Incomplete combustion
Lack of oxygen
Nitrogen oxides
Effects
Destroys vegetation and fish in lakes
Acid rain
Corrodes buildings
Why is it formed?
High pressure and temp in the engine causes nitrogen and oxygen to react together
Escape into the atmosphere and dissolves in the moisture to converted into nitric acid
