Abstract
O-rings are a primary component made from polymeric materials in most diesel engine systems. For oil-fuelled operations, O-rings tend to degrade after exposure to fuel in certain operating condition and periods. Degradation of O-rings can cause engine leakage. This study is intended to test the O-rings material which contacted with biodiesel in dynamic flow by considering the potential deterioration caused. The use of biodiesel may contribute to accelerating deterioration of O-rings. The boiler fuel system was duplicated in this test, where the biodiesel used was palm oil based. The O-rings tested are made of materials of Fluorocarbon elastomer (FKM), Nitrile Rubber (NR) and Silicone Rubber (SR). The effects on O-rings were observed on changes in mass, volume, and thickness. The material compatibility is indicated by elongation, swelling and chemical resistance of elastomers with various fuel flow rates. The fuel flow with high volumetric rate tends to damage the O-rings faster as effected on the immersion test. FKM-Viton performed as materials with the best physical and chemical resistance. Dynamic fuel flow in the engine system showed that SR is deteriorated faster than NBR and FKM. The resistance of O-ring material to fuel in the system is not linearly influenced by the amount of biodiesel in the fuel.
