Latest Developments In Metallic Catalytic Converters To Meet Future Diesel Emission Legislations And Innovative Substrate Designs For Gasoline Vehicles 2004-28-0042
Catalyst in the exhaust system of Light -duty diesel vehicles operating at low temperatures typical of urban driving does not reach light-off temperature. There are options in metallic substrates for close-couple operations for optimum heat utilization to effect higher temperature for oxicat performance and for efficient operation and regeneration of metallic particulate filter, which by itself is an attractive option for EU IV Norm. The present paper gives an account of developments in this field.
Also the paper gives an insight into the developments of new innovative metal foil structures for use in petrol and diesel vehicles, which provides enhanced catalytic efficiencies without increasing cell densities.
