Abstract
The aim of this paper is to provide deeper understanding of the dynamics of automobile exhaust system to provide a basis for the improved design & development of computationally inexpensive theoretical system model. Modeling, simulation & experimental investigation of a typical exhaust system are performed to gain such an understanding & to evaluate modeling ideas. These models incorporate adjustable flexibility in their connection to the exhaust pipes & a procedure is developed for automatic updating of these parameters to obtain better correlation with experimental results. The agreement between the simulation results of the updated models & experimental results is very good, which confirms the usability of these models. The main objective of this project is to design exhaust system and to compare its performance with an existing system available. The newly designed exhaust system shows lower back pressure which ultimately results better performance of the engine. Low vibration levels are critical to achievee in automobile exhaust system . It is therefore important design engineers to be able to predict, explain & assess the dynamics of various system design proposals during product development.
