Automobile Pollution Internal combustion engines need a mixture of air and fuel to burn and produce energy to move the vehicle. It is these burnt gases which come out of the exhaust have the potential to cause pollution. In petrol engines the gases comprise of a mixture of unburnt hydrocarbons (HC), Carbon Monoxide (CO), Oxides of Nitrogen (NOx). It is a combination of these gases that which result in automobile pollution when they are in excess quantity. Within a certain range they are acceptable but when the engine is not tuned properly or a vehicle uses obsolete technology or the quality of fuel is not good then all these result in a higher level of emission of all the gases. If the air fuel mixture ratio is not correct then it increases the chances of pollution as it leads to inefficient. Also it leads to reduced power and fuel wastage, which in turn means less efficient performance of the engine along with lower fuel economy. 1.   Steps to check pollution In an effort to check aut
