Carbon Dioxide CO2
How formed?
 result of perfect combustion
Dangerous?
 Greenhouse Gas
(also CH4; N2O; H2O; O3, … )
 Play significant part in climate change.
 Quantity of CO2 is proportional to fuel
consumption
Hydrocarbon
Hydrocarbons HC
How formed?
 result of unburned fuel
 caused by a misfire, low compression, leaking injector,
extreme rich or lean air/fuel mixture
Dangerous?
 Contributes to SMOG (see also later)
 Cancer
 Asthma
 Liver disease
Carbonmonoxide
Carbonmonoxide CO
Carbonmonoxide CO
How formed?
 result of incomplete combustion
 not enough O2 to burn all the fuel
 caused by a dirty air filter, high fuel rail pressure
Dangerous?
 Extremely toxic, even deadly
 Changes the chemistry of a persons hemoglobin
 Inhibit the body’s ability to transport oxygen through the
blood stream.
Nitrogen Oxides
x
Nitrogen Oxides NOx = NO and NO2
Nitrogen Oxides NOx = NO and NO2
How formed?
 result of N2 combining with O2 in the combustion process
 created by high levels of heat and pressure
 created by lean air fuel mixture
 caused by a faulty EGR, overheated engine, catalyst failure
Dangerous?
 Contributes to SMOG (see later)
 Acid Rain
 Breathing difficulties
Particulate Matter

Smog
What about
Smog
Euro VI
EURO 6
EURO 6
Different vehicles
And when we expect what?
I want you
to present the automotive solutions to EURO 6
At work…
Step one – 4 groups and 4 solutions
3 way
Catalytic
Converter
Exhaust
Gas
Recirculation
Diesel
Particulate
Filter
Selective
Catalytic
Reduction
At work…
Step two – Research + making presentation
+
At work…
Step three – Presentation
Content (obligatory!)
 CHEMISTRY: What happens to what emissions
 MECHANICS: How does the system work
 POSITION: Where is it used (which engine, where is it placed)
 Invent “one slogan” to make the world aware of pollution’s effects
(try to be original, funny, creative, … )
