Major pollutants emitted include:
O Hydrocarbons: this class is made up of unburned or partially burned fuel, and a major contributor to urban smog as well as being toxic. He liver damage and even cancer can be. O nitrogen (NOx) Oxides: These are generated when nitrogen in the air, high temperature and pressure conditions inside the engine to react with oxygen. NOx emissions contribute to both smog and acid rain. O Carbon (CO) Monoxide: a product of incomplete combustion, carbon monoxide reduces the blood's oxygen carrying capacity and is dangerous for people with heart disease. O Carbon dioxide (CO2) emissions of carbon dioxide as its role in global warming is a growing concern as a greenhouse gas than is apparent. O particulates. micrometre-sized particles.
