Design, Analysis And Manufacturing Of Race Car Exhaust System

Abstract

Exhaust Systems for the vehicle are the most crucial system required in the transmission which follow IC Engine  trend. Concerning race car, the exhaust systems determine the performance along with the treatment of Exhaust gases. Mufflers, catalytic converters and resonators make up the system complete for treatment of exhaust gases. Exhaust gases norms getting strict all over the world makes the topic more interesting and important for the innovation and development. In this paper the exhaust system is designed using Volumetric Theory followed by Acoustic Theory specifically the free flow absorptive muffler. In order to optimize the engine performance and the Sound limit, the free flow muffler is designed with minimum back pressure. Further modelled using design software Creo Parametric1.0 and simulation carried by software Ansys (Fluent) and tested by Matlab validates the model. Thermal stress analysis carried in Ansys gives safe results. Mathematically modelled the design and verified with the Simulation results are presented in the paper. Confining to the rule book of GKDC Season6 the acoustic limit of 100dB is achieved that further validates the Vehicle with Technical Inspection OK report.
