Evaporative
Crankcase
Exhaust
Types of Emission

Oxides of Nitrogen(Nox)
Hydro Carbons(HC)
Smoke and Soot
Lead
Sulphuric Oxide

Global Climate Change
Gas and diesel burning vehicles also contribute to global climate change.
The Earth’s atmosphere acts like a blanket, trapping some of the sun’s heat near the planet’s surface. Without this natural insulation, the average temperature on Earth would be -18°C
Vehicle emissions also contain CO2, an important Green house gas (GHG).
If the atmosphere gets too thick with GHGs, too much heat gets trapped. That can mean problems for the whole world.
