Review Study on Catalytic Converter for Emission Control in Diesel Engine

Exhaust pollutants from the automobile engines have negative impact on air quality as well as on human health. Exhaust emission control by catalytic converter, is best way to reduce emission for automotive vehicles. Catalytic converter generally used in modern automobile vehicles is based on noble metal (platinum, rhodium and palladium). Catalytic converter based on noble metal has certain demerits. Research in area of non-noble meal based catalytic converter to be developed for reducing pollution generated by automobile diesel engine. Current study focuses on new developed Ferric Oxide based catalytic converter because existing available catalytic converters suffer from various problems like; poisoning, fracture, melting and higher cost.
