Failure Investigation and Thermo-Mechanical Analysis of Cylinder Liner

Abstract

Internal combustion engine are frequently operated in many mechanical sector applications. It is used in automotive, ships, power aircrafts, power generation units. In Internal combustion Engine, the cylinder liners are the important and the most load carrying part. This liner is subjected to various stresses during the engine working status. The stresses which act on cylinder liner are Stress due to action of gas pressure, heat and pressure of piston acting on liner. Result of that stresses Wear patters developed, Internal or external cracking and Corrosion of cylinder liner takes place. All above results are adversely affects on the performance of cylinder liner, and reduces the working efficiency of internal combustion engine. So, there is need to investigate the various reasons of failure of liner and methods to overcome and increase the efficiency of liner. The most important requirements for the satisfactory service life of the cylinder component in an engine are higher life, higher temperature resistance and higher mechanical properties. In this paper, complete thermo-mechanical analysis of cylinder liner is carried out at different temperature and different pressure.
