Elastomer compatibility testing of renewable diesel fuels
National Renewable Energy Laboratory (U.S.)
21 unnumbered pages : digital, PDF file.
One aspect of this program is to ensure that blends of petroleum-derived fuels and renewable fuels can be utilized without negative impact on engine durability. Materials compatibility is an important component of this research. The blending of renewable components, such as biodiesel or ethanol, into diesel fuel may impact the integrity and performance of various fuel system elastomers. The Southwest Research Institute conducted this work for the National Renewable Energy Laboratory (NREL) as part of a program to determine how ethanol and biodiesel affect these materials. Six elastomers (N1059, N674, N0497, V747, and V884) commonly used in automotive applications were tested with the following fuels: certification diesel fuel, certification diesel fuel blended with 15% ethanol, and certification diesel fuel blended with 20% soy-derived biodiesel.
