Introduction to Fatty Acid Methyl Ester (FAME) biodiesel
FAME biodiesel, called biodiesel fuel in the following section, consists of a family of fuels derived from vegetable oils
treated with methyl esters.
There are two main biodiesel fuel types: Rapeseed Methyl Ester (RME) and Soybean Methyl Ester (SME). RME is a
blend of rapeseed and sunflower methyl ester, and is the preferred crop in Europe. SME is the preferred crop in the
United States.
Biodiesel fuel is a renewable alternative fuel source. Its use and development is promoted worldwide, especially in
Europe and in the United States.
NOTICE: Your emissions control system is compatible with up to 7 % biodiesel fuel (B7). Be aware that the use
of biodiesel fuel that does not comply with the standards mentioned in this section could lead to severe damage to
the engine, fuel system or aftertreatment system of your machine. The use of non-approved fuels may void NEW
HOLLAND CONSTRUCTION Warranty coverage.
Biodiesel can be used to run Tier 4b diesel engines only when blended with standard diesel fuel:
• B7: indicates the blend of 7 % biodiesel and 93 % diesel fuels.
• B20: indicates the blend of 20 % biodiesel and 80 % diesel fuels. Do not use.
Biodiesel fuel has several positive features in comparison with diesel fuel:
• Biodiesel adds lubricity to the fuel, which is beneficial in many circumstances, particularly as sulfur and aromatics
are removed from the fuel.
• Biodiesel has a greater cetane number and burns cleaner.
• Biodiesel produces less particulate matter and reduces smoke emissions.
• Biodiesel is fully biodegradable and non-toxic.
Diesel and biodiesel fuel specifications
Tier 4b diesel fuel specifications are covered by the following:
• EN 590 - Specification of Diesel fuel. (10 ppm sulfur maximum.)
Biodiesel blends are covered by:
• European Diesel Fuel Specification EN 590 allows up to 7 % biodiesel since 2009. European fuel suppliers are
allowed to use up to 7 % biodiesel fuel (B7) to supply the network.
Pure biodiesel blend stock (B100) specification is covered by the following requirements:
• Europe: EN14214 - Automotive fuels. Fatty Acid Methyl Ester (FAME) for diesel engines. Requirements and test
methods.
• DIN V 51606 - German standard for biodiesel.
Before raw oil can be converted into usable biodiesel fuel, it must undergo transesterification to remove glycerides.
During the transesterification process, the oil reacts with an alcohol to separate the glycerine from the fat or vegetable
oil. This process leaves behind two products: methyl ester (the chemical name for biodiesel) and glycerine (a byprod-
uct usually sold for use in soaps or other products).
NOTICE: Biodiesel fuels approved for use in the NEW HOLLAND CONSTRUCTION equipment must be transesteri-
fied and comply with the European Standard EN14214 or the German standard DIN V 51606.
NOTICE: Cold Pressed Biodiesel, Cold Pressed Oil, Straight Vegetable Oil (SVO), or more generally unrefined veg-
etable oils used as motor fuel, are fuels that are normally made from Rapeseed oil or similar high oil content crops.
These kinds of fuel are not transesterified, so they do not fulfil the EN14214 requirements. There is no recognized
quality standard available for these types of fuel. Therefore the use of Cold Pressed Biodiesel, Cold Pressed Oil,
