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 ...

Presented considerations of this work includes selected issues in the area of statistical procedures use in vibration measures study and modal analysis methods to assess the building structures and machines state. The indicated statistical procedures are particularly important in vibration and modal research, where the multidimensionality of diagnostic signals requires a wide ...
