Abstract
The discrepancy between measured and calculated oil-film thickness under a piston ring is shown to be due to oil starvation. If care is taken to keep the inlet region filled with oil, the film thickness is found to obey the theory. A simple formula is derived for predicting the degree of starvation to be expected when more than one piston ring is fitted.
