Investigation of exhaust emission and optimization of cell shape catalytic converter using Ag, Au and SS 304 on IC engine

Abstract

Catalytic converter used in automobile to reduce exhaust emission by converting high toxic gases into less
toxic gases. The main pollutant gases in the automobile are HC, CO and NOX. These gases are treated in catalytic
converter and converted into water vapor and CO2 which is less toxic. Noble metal based Catalytic converter face some
problem like; poisoning, melting and higher cost these leads to application of non-noble metal based material such as
copper, silver, gold or combination of these material as catalysts. In present work the catalytic converter is developed
using gold coating wire mesh, silver coating wire mesh and SS coating wire mesh. It is found that silver coated and gold
coated material gives better results.
