Abstract: This paper presents characteristics of a new catalytic converter to reduce NOx in the exhaust gas in S.I engines. The catalytic converter was developed based on catalyst materials consisting of “Natural Zeolite” with wire mesh substrate. In our design “Zeolite” in powder form is coated over the stainless steel wire mesh and a new catalytic converter was fabricated to reduce NOx as well as HC. We used Gas Analyzer Kit to measure the exhaust gas properties. Initially experiments were conducted on the zeolite coated converter and the results were compared with conventional catalytic converter.
