This paper presents the results of studies on the influence of unbalance of the rotor unit of a turbocharger on its operational parameters. Identification of the study object, a turbocharger of the NAPIER C-045 type, has been performed. The experiment was carried out at a test stand identifying turbocharger operational parameters belonging to the rotor unit unbalance group. Basing on the measured values and using a mathematical model, hypothetical values of operational parameters for different loads of Diesel engines were calculated. The obtained experimental results were compared to the calculated ones. On this basis, the studied turbochargers were classified into one out of three categories describing operational utility class of a given turbocharger. The order of sensitivity of turbocharger operational parameters to the unbalance of the rotor unit was established.
