This master’s thesis deals with mechanical losses in turbochargers. The theoretical part provides general information of the methods of support the turbocharger rotor, then focuses on hydrodynamic bearings. The thesis analyzes the occurrence of mechanical losses and the effects that affect them. An important part of this thesis focuses on the determination of mechanical losses and their possibilities. A test stand was compiled for the possibility of experimental measurement of mechanical losses. Several test measurements were performed on this test stand at different operating modes. Simultaneously, the determination of mechanical losses was performed using two other methods. Based on these measurements, it was also possible to perform an evaluation and analyze the occurrence of mechanical losses depending on the set operating conditions. A comparison of individual methods for determining mechanical losses performed in the experimental part was performed. At the end of the thesis, the possibilities of the test stand were defined based on the performed measurements.
