3D Modeling, Analysis, and Construction of an Exhaust System in a Formula Student Car

This paper presents a new stainless-steel exhaust manifold system designed for a Formula Student racing car. The exhaust system meets the Formula Student regulations and is designed to be mounted on a 600 cc engine. Special consideration was given to the aspect of fitment, due to the fact that the engine will fit on a steel tube chassis. The design of the exhaust system considers the importance of equal-length runners and the individual primary exhaust pipes of the header, which are ideal for increased engine performance. For the simulations, the ANSYS FLUENT 12 was employed. For the investigation of the exhaust gases’ characteristics, the governing equations of the k-ε model were employed.
