Its main purposes are to seal the combustion chamber of the engine, minimize the friction against the cylinder liner but also transfer heat from the piston to the cooled cylinder liner. Another important property of the piston ring is to evenly distribute oil along the cylinder liner in order to avoid engine seizure. There are two types of piston ring: compression ring and oil ring. Automobile reciprocating engines normally use three rings, two compression rings and one oil ring. Piston ring moves freely within its groove. Such movements depend on the forces and the moments acting on the piston ring system such as: the static ring tension from installation of piston ring in the cylinder liner, the gas pressure forces caused by cylinder pressure and blow-by gas, the hydrodynamic forces caused by lubricant film, the inertia forces related to component mass and engine speed, and asperity contact forces caused by a direct contact to the cylinder walls. Working conditions of piston rings are very demanding and it is desirable to understand the design of such component subjected to various loads. Recently, finite element analysis has played major role in automotive industry to design various components of automobile. Hence, this work aims to design and analyze the piston ring using commercial FEA tool like ANSYS. Structural designs of piston rings are not studied adequately. Hence, this work aims to study structural design and analysis of piston rings subjected to static loads.
