Engine is the heart of automobiles and valve mechanism is the heart of engine. There are two types of the valves are
used in internal combustion engines which are intake valve and exhaust valve. Intake and exhaust valves are used to control the
flow of intake fresh charge and Exhaust flue gases alternatively in Engine. They are used to seal the working space inside
cylinder against the manifold and they open and close by means of what is known as the Valve gear mechanism. Exhaust valve
work well in engines because the pressure inside the combustion chamber pushes valve against the seat, sealing the chamber and
preventing leaks during this cycle exhaust valves are exposed to high temperature and pressure which will affect the life and
performance of the engine. The aim of the project is to design an exhaust valve with a suitable material along with the three
different fillet radii for a four-stroke diesel engine by using Finite Element Analysis. In exhaust valve we have considered
