Abstract

With the new pollution control rules and surging requirements for the increase in efficiency of the internal combustion engines, designing the exhaust manifold has become a growing area of interest. The present work focuses on modelling the multi-end exhaust manifold and comparing it with the single-end exhaust manifold. Both the structural and thermal analyses are carried out using the finite element method. Along with the modified design, various materials such as mild steel, cast iron, stainless steel and medium carbon steel are also evaluated for their structural and thermal behaviour. It is found that the multi-end exhaust manifold performs better in terms of better stress and temperature distribution in comparison to the single-end exhaust manifold. The magnitude of the stress experienced by multi-end exhaust manifolds is 20 MPa lesser than single-end exhaust manifolds. However, the change in material has a marginal effect in terms of stress and temperature distribution.
