Abstract

This study focuses on investigation of the effect of inlet pipe angle in catalytic converter. The catalytic converter is used to catalyst the emission gases from engine combustion, converting the harmful gases into less toxic gases. Until the present day, the catalytic converter has improved the performance of the vehicle start from it launched into production. In order to give the best performance of catalytic converters, the geometry of the catalytic converter must be exact to avoid the behaviour of backpressure in the exhaust system. The backpressure actually reduced the vehicle performances and increase in fuel consumption. Thus, this study aims to design various models of catalytic converter and optimized the volume of fluid flow inside the catalytic converter by changing the inlet cone pipe angles. There are three different angles of inlet pipe that being considered which are 30°, 45°, and 60° degrees. Additionally, two different types of fluid flow are also studied which are air and gas (Carbon Monoxide, CO). The model is simulated in SolidWorks software to achieve the result of this study. From the result, the design of catalytic converter is a critical issue to determine the optimum geometry design of catalytic converter. From the result obtained, it is clearly showed that by decreasing the divergence angle can increase the performance of catalytic converter. The pressure at inlet is directly proportional to inlet angle. Thus, in order to increase the flow uniformity (lower pressure) the inlet divergence angle of catalytic converter should be decreased.
