Abstract
An exhaust manifold or header collects the exhaust gases from multiple cylinders into one pipe. Exhaust manifolds are generally simple cast iron or stainless steel units which collect engine exhaust gases from multiple cylinders and deliver it to the exhaust pipe. The goal of performance exhaust headers is mainly to decrease flow resistance, and to increase the volumetric efficiency of an engine, resulting in a gain in power output. The exhaust manifold has to withstand the pressure of exhaust gases and amount of heat generated in the engine. A parametric model of exhaust manifold has been developed to predict the transient thermal behavior. The parametric model is created in 3D modeling software Pro/Engineer. Present used materials for exhaust manifold are cast iron or stainless steel. Steady thermal analysis is done on the exhaust manifold to determine variation temperature distribution over time. The analysis is to be done using Stainless Steel are present used materials. We compare the results to verify the best material for exhaust manifold .Steady thermal analysis determines temperatures and other thermal quantities that vary over time. The variation of temperature distribution over time is of interest in many applications such as with cooling. The accurate thermal simulation could permit critical design parameters to be identified for improved life. The analysis is done using ANSYS on workbench of Steady state thermal analysis performed for calculating the heat flux and thermal difference or analytically heat flux is also calculated in this analysis. Select the optimum design and its behavior of physical properties.
