✦ Synopsis
An experimental study is presented to evaluate the effect of partial laser surface texturing (LST) on friction reduction in piston rings. Tests were performed on a reciprocating test rig with actual piston rings and cylinder liner segments. A comparison was made between the performance of a reference non-textured conventional barrel shape rings and optimum partial LST cylindrical shape rings. It was found that the partial LST piston rings exhibited about 25% lower friction.
