When all of the engine’s emissions are gathered in one location and fully burned, the exhaust manifold functions as a funnel and directs the emissions into the remaining exhaust system. The creation, development, and manufacturing of a novel exhaust manifold with excellent thermal conductivity is the goal of this project. It also entails not transferring heat to the engine and maintaining a low manifold surface temperature. An analysis of an exhaust manifold system’s heat transfer properties is presented in this work. The experimental setup includes a mild steel manifold, SS 304 manifold, and heat wrap. The performance of the system is analysed under different conditions with heat wrap and without heat wrap on MS and SS 304 exhaust manifold. The results show that the system can achieve a maximum thermal conductivity in SS 304 manifold wrapped with glass fibre heat wrap. The study also investigates the effect of different manifolds’ thermal conductivity on the system`s performance. Overall, this study provides valuable insight into the heat transfer mechanisms of exhaust manifold and their potential to become efficient for single-cylinder engine.
