ABSTRACT

The hot scuffing phenomenon of a piston ring in ring groove is one of the important failure mechanisms in an automotive engine. The dynamic motion of a piston ring against the ring groove is very complicated. Five motions are usually involved, including radial sliding, circumferential sliding, impacting, rocking and tilting. Experimental or theoretical studies in this field are rarely reported. To investigate the hot scuffing behavior of piston rings run against various coated ring grooves, a previously developed tester with the ...
