PISTON RING

To provide a piston ring which, when used in a high-output engine, can sustain an excellent effect of suppressing aluminum adhesion, over a long period. Either or both the upper and lower sides of the piston ring are covered with a resin-based film containing a fibrous filler with a mean fiber diame...

Zusammenfassung:	To provide a piston ring which, when used in a high-output engine, can sustain an excellent effect of suppressing aluminum adhesion, over a long period. Either or both the upper and lower sides of the piston ring are covered with a resin-based film containing a fibrous filler with a mean fiber diameter of 50 to 500 nm and an aspect ratio of 30 to 500. The fibrous filler content is 0.5 to 10 vol% with respect to the total resin-based film. Also, the fibrous filler used is at least one type from among carbon fibers, silica fibers and boron nitride fibers.
