Design and Analysis of Poppet Valve Using Composite Materials

Poppet valve is a precision engine component which blocks gas flow ports and controls the exchange of
gases in internal combustion engines. Intake and exhaust valves are known as "poppet" valves. Poppet
valves have a round head that blocks a Hole (the "port") the "stem" attached to the back of this "valve
head" pushes the valve up and away from the port, allowing air/fuel to flow through the gap between the
valve head and valve seat and into the combustion chamber. Poppet valves work well in engines because
the pressure inside the combustion chamber pushes the valve against the seat, sealing the chamber and
preventing leaks during this cycle poppet 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 and analysis of poppet
valve with a suitable material using Finite element Method. 3D model is done in CATIA and Analysis is
done in ANSYS. Thermal and structural analysis is to be done on the poppet valve when valve is closed.
