Thermal analysis of two wheeler exhaust pipe by Finite element method

Abstract

Exhaust system in the bike is an important part of the motorcycle which play an important role in both economy and engine performance. Usually the exhaust pipe in general is used to carry the burnt gases from the outlet valve of the cylinder to the atmosphere. Depending on the capacity and engine design there might be one or more exhaust pipe. High pressure high temperature exhaust gas enters the exhaust pipe which should be cooled and is converted to non-polluting gasses.

The problem identified for this journal work is to ensure the uniform heat flow along the passage of hot gases and design the passage surface such has to identify the harmful effects of hot-spots over the length of the exhaust pipe especially at the outer body of exhaust pipe. And enhance the life of exhaust pipe. The Exhaust pipe is considered which is modelled by CATIA V5 and is thermally analysed in ANSYS 19 where we find the percentage of elements at the different temperature.
