This article describes the shift of the subsynchronous frequency due to change in lubricant temperature. A small diesel turbocharger for a passenger vehicle with semi-floating bearing system was investigated. Measurements were taken on a combustion engine using an external device as a source of lubricant for the turbocharger. Two temperature regimes were selected, 30 degrees C representing cold lubricant conditions, and 100 degrees C as the normal operating temperature. Lubricant pressure level was maintained at 1 bar during the entire test procedure. Results show the significant influence of lubricant temperature on the subsynchronous frequency of rotors.
