Thermal deformation of cast iron exhaust manifold for turbo diesel engine is investigatedby finite element analysis (FEA). The FE model includes the temperature dependent materialproperties as well as the interactions between exhaust manifold, cylinder head and fasteners. It alsoconsiders the sliding behavior of the flanges of exhaust manifold on cylinder head when eitherexpansion or contraction of the exhaust manifold exceeds the fastener pretension. The result ofanalysis revealed that remarkable thermal deformation occurred along the longitudinal direction.The amount of deformation was predicted and compared with experimental results. The new designof fastener hole, which allows sliding behavior, is expected to reduce thermal stress in turbo dieselengine exhaust manifold
