A number of analytical studies have been made on piston-related noise. However, ring-related noises have been little studied, and there has been no report to date dealing with this noise specifically. In order to reveal the mechanism of producing piston ring noise from a gasoline engine during idling, the piston secondary motion and the vertical direction oil ring motion have been analyzed. This analysis has turned out that the stick-slip phenomenon of the upper side rail of the oil ring occurs in the vertical direction. Also factors of the stick-slip have been studied in terms of friction of the piston ring.
