Beschreibungen/Notizen

• High noise generated by the engine of a two-wheeler scooter has been analysed. Sound intensity measurements were performed on the engine to identify the sources of high noise. Sound intensity maps and intensity spectra of the engine were obtained. The measurement results indicate that the high noise was mainly generated by the cylinder of the engine. Piston slap and resonance of cylinder head fins were identified as the causes of high noise. Substantial reduction in the engine noise was obtained when the piston-cylinder clearance was reduced and the natural frequencies of the cylinder head fins were changed.
