Abstract

 turbocharger improves efficiency by using exhaust gas energy that would otherwise be lost and plays a huge role in meeting current & future fuel economy, performance goals and due to effective combustion reduces environmental pollution. Due to different duty cycles, there are many failures and one of sever and most frequent is oil leakages from compressor and turbine side. Major failure modes of oil sealing leads to clogged air filter, gas leak in exhaust manifold to engine join, damaged turbo, obstruct turbo oil drain line, bearing housing coked & worn engine rings. It is important to keep oil away from the compressor and turbine rotor seal areas, because it can contribute to emissions. Oil sealing in turbocharger play very important role in meet anti-pollution legislation standard. Leakage being the major issue for engines & turbochargers, oil sealing is considered as the critical while designing sealing. These failures occur because of the lack of understanding of the oil leakage from turbocharger. In this paper, different seal design & fea parameters have been analyzed for predicting the behavior of the systems very accurately and efficiently. Study for understanding performance of oil sealing capability of turbocharger from different research papers which help to understand assumption made, analysis carried and different ways for oil sealing capability. Ian sherrington, neil grice, and john clifford jackson (1993)[7], did research & able to identify oil leakage at the turbine end of a turbocharger
