Abstract
Diesel is an important fuel used as alternative to extend the usefulness of petroleum, and the longevity and cleanliness of diesel engines. Engineering polymers have great importance in the industry thanks to the years of improvement in their properties, which allowed equipment manufacturers to replace metals by polymers. Often, polymers are in direct contact with fuels and understand its compatibility is primordial. Polyoxymethylene (POM) is thermoplastic used to manufacture automotive fuel pump gears and rotors due to its low coefficient of friction and thermal and dimensional stability. In this study, POM was immersed in Diesel at different temperatures (-10ºC, 23ºC and 60ºC) for 1000, 2000, 3000, 5000 and 10000h. After degradation, tensile tests were performed to evaluate the material mechanical properties and analyze the effect of Diesel degradation.
