This work studies the influence of the cross-hatching groove parameters on a model piston ring load carrying capacity. Over 2000 transient calculations were performed varying all parameters (groove depth, groove width, groove angle, and the distance between cross-overs) to obtain the average load carrying capacity. It is shown that the load carrying capacity results fall close to a single master curve when using the Delta parameter that is a combination of the groove parameters. Finally, the influence of the starvation level on load carrying capacity was analyzed.
