Abstract The request for constantly decreasing noise levels in the interior of modern vehicles leads to highest requirements in terms of their vibroacoustic performance. Here, the analysis of the transfer paths both of structural and airborne noise evoked by the tire/road contact is as significant as the characterization of the sound and vibration emitted by present-day drivelines and all its components. Regarding combustion engines, the application of direct injection systems is state-ofthe- art both in gasoline and diesel engines. Due to very high pressures, modern injection systems guarantee fine hydraulic atomization and better mixture preparation. In turn, these effects lead to benefits both in efficiency and emissions.
