The complex mechanical loads acting on turbocharger during their lifetime necessitated the study and optimization of the rotordynamics and tribology system of turbochargers. The technical developments that aim to improve the efficiency of internal combustion engines, such as changes in the quality and composition of lubricants, can also indirectly affect the operation of the turbocharger, and cause some cases unexpected failures. The paper summarizes the diagnostic methods used in this topic and conclude potential fields for further optimization opportunities.
Kivonat
A turbófeltöltőket élettartamuk során érő összetett mechanikai terhelések szükségessé tették a feltöltők rotordinamikai-tribológiai rendszerének vizsgálatát és optimalizálását. A belsőégésű motor hatásfokának növelését célzó technológiai fejlesztések, például a kenőolaj minőségének és összetételének megváltoztatása közvetetten is hatással lehet a turbófeltöltő működésére, esetenként nem várt meghibásodására. A tanulmány összefoglalóan bemutatja az ebben a témakörben eddig használatos diagnosztikai módszer eket és lehetőségeket.
