PISTON RING AND CYLINDER WEAR - AN APPRAISAL OF CURRENT PROBLEMS 540190

No profound or basic discoveries eliminating wear of the subject parts are reported in this paper, but data and observations on some speculative aspects are presented. The data offered is, in itself, largely inconclusive, but may enable others to view their data from new angles and may inspire some new approaches to solution of old problems.
It is shown that wear rates are subject to wide and unexplained variation. An analysis of possible factors on this variation is made.
Is wear increased by extremely low oil consumption? Some new data on this old question is offered.
Finally, an analysis of characteristics of the new engines is made, indicating that we may be facing some new problems.
