In developed and developing countries, the history of air pollution problem has typically been high levels of smoke and sulphur dioxide arising from the combustion of sulphur-containing fossil fuels such as coal for domestic and industrial purpose.[i] Industrial development and the use of fossil fuels have affected the world climate adversely.

Motor vehicle use is now generally recognised as the source of more air pollution than any other single activity in cities around the world. The internal combustion engine of a vehicle produces power by burning fuel and changing the chemical energy of fuel into heat energy. The heat energy is then converted into mechanical power. Cars and trucks do not burn all of the fuel that goes into the combustion chamber. In fact, most vehicles only burn about 85% of the fuel and as the vehicle gets older less and less fuel is burned. It is this unburned fuel that produces some harmful products which are discharged from the engine and become air pollutants.[iv] Therefore, an engine’s fuel system, and its emission controls are closely interrelated. That is why attention is given to the requirements of emission control in the design and operation of all parts of the fuel system in a vehicle. EFFECTS OF POLLUTANTS IN VEHICLES 6. Adverse effects to human health include; a. Reduction in the amount of oxygen that can be delivered to our body’s organs and tissues, which can be life threatening caused by particles of carbon monoxide.
