Exhaust Analysis of C.I Engine by Using Zirconium Dioxide Coated Wire Mesh Catalytic Converter

Exhaust emissions is much concern about the Hydrocarbon (HC), Carbon Monoxide (CO) and Nitrogen Oxide (NOx) from the automotive vehicles. This paper presents characteristics of a catalytic converter to be used for four stroke four cylinder diesel engines. Catalytic converter with different catalyst for diesel engine to reduce pollute gases is chosen for present work. The emphasis is given on hydrocarbon (HC), carbon monoxide (CO) and oxides of nitrogen. The wire mesh is developed as catalyst. The wire mesh is coated with zirconium dioxide (ZrO2). The catalyst materials are inexpensive in comparison with conventional catalysts (noble metals) such as palladium or platinum. Catalytic converter oxidizes harmful CO and HC emission to CO2 and H2O in the exhaust system and thus the emission in the automobile vehicle is controlled. Emission of HC, CO and CO2 was measured and monitored for conventional OEM catalytic converter system with ZrO2 coated wire mesh catalytic converter system. Performance of catalytic converter is depends upon temperature. Optimized temperature was found for ZrO2 coated wire mesh catalytic converter for best performance. Effect of wire mesh on break specific fuel consumption and brake thermal efficiency were recorded and analyzed. The back pressure of the exhaust gases is measured by putting different number of wire mesh in the catalytic converter.
