A NEW TEST FOR SEALS: HIGH TEMPERATURE RESILIENCE

This paper describes the modification of the Yerzley Oscillograph specifically for measuring the resilience of Zero Blow-By Seals. The modified screening tests proved to be an efficient means of evaluating effects of compounding variables such as differences in the base polymer or filler loading, fuel, fuel additives, and engine oil on the resilience of seals at various temperatures. Correlation with dynamometer performance suggests resilience of about 40 percent at engine operating temperature required for the elastomer seal to perform properly.
