Introduction The use of catalytic converter to reduce emission from vehicle exhaust has been recently. Mostly the cataytic converter used for motor vehicles (on the market) is in a type of pellet and monolithic catalysts and the materials made from nobel metals, such as palladium (Pd), Platinum (Pt) and Rhodium (Rh) [1]. Those metals have a high specific activity, a large degree of volatility, easily oxidized and easily broken at temperature of 500-900 o C, which result in reducing activity of the catalyst. Besides these metals have a low availability and quite expensive [2] The installation of the catalytic converter on exhaust channel with catalysts of Pd, Pt and Rh with alumina, silica and ceramic buffer, are quite expensive in facrication, difficult to find and less suitable used in Indonesia, because most of fuel still contains high Pb. However, this type of catalytic converter can convert exhaust emissions (CO, HC and NOx) with quite high conversion (80-90 %) [3]. These information lead us to search new alternative for new materials and lower price. For this alternative, the transition metal oxides are the promising options to oxidize CO emission such as CuO, NiO and Cr2O3. The materials known as oxidation catalyst are Platinum, Plutonium, Nickel, Manganese, Chromium and other metals oxides forms, while some metals are known as a reduction catalyst, i.e. iron, copper, nickel alloys and these materials oxides [4]. Besides, some metals known to be effective as an oxidized and reduction catalyst materials, ranging from large to small are Pt, Pd, Ru > Mn, Cu >> Ni > Fe > Cr > Zn and oxides of these metals [5]. Thoese types of catalytic converter can reduce exhaust emissions (CO, HC, NOx) between 16 % to 80 % [6]. The other alternatives are modification of the exhaust duct in motor vehicle[7]. Therefore, how is the ability of an catalytic converter to reduce exhaust emissions need to be conducted. This study aims to design or to create a tool to reduce exhaust emissions of motor vehicles often called as catalytic converter in variation of Manganese-Coated Copper Catalyst. This tool is particularly to reduce exhaust emissions of carbon monoxide and to find optimum design. 2. Methodology This research is based on the ideas and stages that are systematically arranged. The initial phase of the research is conducted by library research to deepen the fobject to be researched, both the problems of air pollution and emission control technologies, especially in the design of Catalytic Converter. This library research on the previous research is used as the basis in comparing the results of the research with the previous research, so the originality of the research is maintained and there is no duplication of the research. 2.1. Research Material The research material consists of two main parts: the inside and outside construction of Catalytic Converter. The inside construction consists of a substrate and washcoat material made of copper metal as the catalyst, whereas the outer form of the catalyst (Chasing) is made of Stainless Steel and support / sustainer. [8] The inside substrate material is made of Manganese-Coated Copper with the size of 160 mm x 100 mm in oval shaped adjusted with the shape of chasing and half of the area is given 2 mm holes with 3 mm space between holes. ۲٫۲٫ Chasing Chasing is the outside part of a Catalytic Converter that is chose based on the general shape, mostly use which is made of Stainless Steel plate [9]. It has a cover that can be opened and closed with bolts like a drawer, during the turn of cells number variations in the inisede frame. It is installed asbestos to protect the inside with the outer construction, vibration damper, thermal insulator and to avoid leaks of the exhaust gases. The edge of Chasing is installed with flange (cantilever) and exhaust packing, so that the conditions of Catalytic Converter is really tight and toned at the time of installation and no leak of gas emissions when tested.
