In order to increase the filling of the cylinder in the engine, a so-called charge is applied, which consists in increasing the amount of air input under increased pressure and at an unchanged temperature. This increases the density of that air and increases the mass in the engine cylinder. In most cars, the charging is carried out by an exhaust gas turbocharger or a mechanical compressor. This paper presents the issues that concern the failure of turbochargers resulting from their balance by weight reduction method. Selected aspects concerning consequences of incorrect balancing and methods of reducing unbalanced rotor mass. A key part of the work includes a proposal to balance turbochargers of automotive vehicles using the "weight-adjustment"method. In this scope, preliminary studies were presented, and conclusions observed during their implementation were described.
