摘要：A catalytic converter is an emissions control device that converts toxic gases and pollutants in exhaustgas to less toxic pollutants by catalyzing a redox reaction. The need for designing the catalytic converters arisesbecause of the increasing pollution caused by vehicles. During Earlier times there were no vehicles resulting in veryscarce pollution, In recent times the Vehicles are increasing and the need to stop the carbon emission and other harmfulgases are bound to increase. This paper focuses how to manufacture a catalytic converter and the effect of backpressure and various dimensions of a catalytic converter. The design of oxidation catalytic converters, 3-way catalyticconverters and/or SCR systems involves the determination of the loading of precious metals, and wash coatformulations. Material choice, and geometric configuration of the components of exhaust systems, (including manifolds,diffusers, setting chambers, converter housings, substrates, and contractions), and the positioning of the converter in theexhaust lines are other important design aspects. Since the 1970s significant knowledge regarding the manufacturingand utilization of catalytic converters for internal combustion engines has been acquired. However, the design ofcatalytic converters is still more of an empirical practice than a science. The balance of the situation may need to beshifted toward the latter as the emission standards become more stringent.
