Used of Catalytic Converter for Automotive Exhaust Emission

In today’s world. Air pollution generated from mobile sources is containing the pollutants which are hydrocarbons (hc), carbon monoxide (co), and nitrogen gases (nox). These air pollutants ar harmful to plants and animals, as well as creature. Number of alternative technologies is used to reduce the harmful emission like improvement in engine design, fuel pre-treatment, use of alternative fuels, fuel additives, exhaust treatment or better tuning of the combustion process etc. among all the types of technologies use of catalytic converters is the best way to control automotive exhaust emissions. This review paper discusses the need to control engine emissions & used of catalytic converter to reduce the emission levels of the engine. As well as review paper discusses about history of catalytic convertor, types of catalytic convertor, limitation of catalytic convertor and also achievements of catalytic convertor.
