Abstracts: Internal Combustion Engines generate undesirable emissions during the combustion process. The exhaust gas sent into the atmosphere by the engine contains hydrocarbon (HC), carbon monoxide (CO) and nitrogen oxide which are major constituents of air pollution. Catalytic converter oxidizes harmful CO and HC emission to CO2 and H2O in the exhaust system and thus the emission is controlled. There are several types of problems associated with noble metal based catalytic converter. These factors encourage for the possible application of non-noble metal based material such as copper as a catalyst. The present work is focused upon the reduction of exhaust emission only using copper as a catalyst in catalytic converter. Though not a noble metal, copper works as a catalyst for the conversion of pollutants in exhaust but in a limited proportion. This catalytic converter based on copper as catalytic is efficient and economical.
