ABSTRACT

Exhaust manifolds are generally simple cast iron, stainless steel and cast iron (GJV SiMo)   units which collect engine exhaust from multiple cylinders and deliver it to the exhaust pipe.

In this project the strength analysis and thermal deformation of cast iron (GJV SiMo) exhaust manifold for two cylinder engine is investigated by finite element analysis (FEA). The software’s used are PRO-E 4.0, HYPERMESH-10 and ANSYS-11 the FE model includes the temperature dependent material properties as well as the interactions between exhaust manifold, cylinder head and fasteners. The result of analysis revealed that remarkable thermal deformation and stresses occurred along the longitudinal direction. To analyse the exhaust manifold for the pressure loads and the thermal loads. The stresses in pressure loads, thermal loads and combined loads simulations are below yield strength at elevated temperature.

Keywords:  Exhaust Manifold, Modal and Thermal analysis, Finite Element Analysis.
