There are three sources of automotive pollutants: Crankcase fumes, exhaust gases and gasoline evaporation. The pollutants formed from these substances fall into three categories: unburnt hydrocarbons (HC), carbon monoxide (CO) and oxides of nitrogen (NOx). The equipment that is used to limit these pollutants is commonly called emission control equipment.
