In this paper, the effects occur in parts of internal combustion engine turbocharger, which have been tested in critical lubrication conditions (low pressure in the lubrication system, reduced oil flow in the axial bearing, and lubrication interruption). The purpose of these tests was to obtain evidence of damage having different parts of turbochargers, once these have failed tests under controlled parameters. With this work, a contribution is generated to identify the causes of failures that occur in turbochargers. With this identification of fault generate a contribution to the possible improvement in the design of the different parts of turbochargers and contribute in improving management control of the internal combustion engines to avoid these faults.
