PD CEN/TR 16557 discusses automotive fuels. Currently, the majority of motor vehicles worldwide are powered by gasoline or diesel. PD CEN/TR 16557 provides background information to the deliberations within CEN that led to establishing a specification for blending from more than 10 % (V/V) up to 30 % (V/V) of fatty acid methyl ester (FAME) in diesel fuel to be used in the captive fleet application for designated vehicles. PD CEN/TR 16557 gives guidance and explanations to the producers, blenders, marketers, and users of high FAME diesel blends (B11 to B30).
The sole designation “Bxx” refers to a FAME-diesel blend where “xx” is the specific FAME content in volume percentage. The connotation “Byy fuel” is used in PD CEN/TR 16557 for a fuel with a defined range of FAME allowed and having “yy” volume percentage of FAME content as the maximum of that range.
PD CEN/TR 16557 on users of high FAME diesel blends is useful for:
Other energy sources include ethanol, biodiesel, propane, compressed natural gas (CNG), electric batteries, and hydrogen (either using fuel cells or combustion). There are also cars that use a hybrid of different power sources. PD CEN/TR 16557 specifies requirements and test methods for marketed and delivered high FAME (B30) fuel for use in diesel engine vehicles designed or subsequently adapted to run on high FAME (B30) fuel. High FAME (B30) fuel is a mixture of more than 10 % (V/V) up to 30 % (V/V) fatty acid methyl esters (commonly known as FAME) complying with EN 14214 and automotive diesel fuel complying with EN 590. For maintenance and control reasons it is to be used in captive fleets that are intended to have appropriate fuel management.” Worldwide, energy policymakers are increasingly keen to move away from petroleum-based fuels to more diverse and renewable sources of energy for reasons of environmental protection, energy security and continued economic development. As an alternative to diesel fuel, many countries use fatty acid methyl ester (FAME) as a biologically based alternative. With this “biodiesel” good experience has been observed and it has resulted in many specification standards, of which EN 14214 (now in its third revision) is the best example. It is a specification fit for all types of diesel engines, where especially the demands of light-duty, Euro V and beyond engines scrutinise the biological product. Using PD CEN/TR 16557 you can provide guidance and explanations to the producers, blenders, marketers, and users of high FAME diesel blends.
