Investigating Fuel-Alcohol Effects on Elastomer Components of Diesel Injector Systems

Abstract

An investigation was conducted to define possible deleterious effects on injector system "o-ring" components resulting from additions of freeze-point depressants to diesel fuel. An accelerated test method was subsequently developed to determine the compatibility of fuel-alcohol mixtures with a variety of molded "o-ring" components currently in use by equipment manufacturers. It was found that as low as three percent additions of ethanol to diesel fuel resulted in significant losses in elastomer properties. In addition, the incorporating of a stress mode of exposure enhanced the degradatory effects of alcohol-fuel mixtures or the test "o-ring" components.
