Design the Exhaust System for the Two Wheeler and Analysis using FEA

An exhaust system is usually a piping used to guide reaction exhaust gases away from the controlled combustion inside an engine. Pressure drop across the exhaust manifold requires to be dealt with by engine and extra power of engine will be used in forcing the exhaust gases from exhaust valve to exit of the exhaust pipes. In this paper the focus is on finding remedies to reduce the pressure drop across the system of the exhaust. A geometry of the exhaust system for 100 CC four stroke SI engine for two wheeler vehicles is created using SOLIDWORKS 2015 software and flow analysis is ran on the module using ANSYS fluent 16.2. Different changes in the geometry of the exhaust assembly are done and effect of those changes on the pressure drop across the exhaust is measured. In final iteration it is successfully identified the area of improvement to reduce pressure drop and have achieved maximum pressure drop reduction up to 70 % is achieved.
