6. Bio-derived Products and Fatty Acid Methyl Esters
Such components can be found in diesel engine fuels and can cause a decrease of
greenhouse gases and SOx emissions. Most bio-fuel components in the diesel pool
are Fatty Acid Methyl Esters (FAME), which come from a special chemical treatment
of natural plant oils. These components are mandatory in automotive and agricultural
diesel in some countries. FAME is specified in ISO 14214 and ASTM D 6751.
FAME has good ignition properties and very good lubrication and environmental
properties, but the other properties that follow about FAME are well known:
D Possible oxidation and thus long term storage problems.
D A chemical force that causes fuel and water to combine
D Microbial growth can appear in the fuel
D Unsatisfactory low temperature properties.
D FAME material particles can appear on exposed surfaces and filter elements.
Where FAME is used as a fuel, make sure that the on board storage, handling,
treatment, service and machinery systems can be used with such a product.
7. Fuel Additives
Usually, fuel additives are not necessary to make sure of the satisfactory operation of
fuels that obey the ISO 8217:2010 standard. But some operators can use specified
additives to change the effect of some fuel properties. Wärtsilä Services
Switzerland Ltd. can make an analysis of such additives and supply a No Objection
Letter for specified additives if they are in the limits of internal specifications.
Note: Winterthur Gas & Diesel Ltd. and Wärtsilä Services Switzerland Ltd. do
not accept liability or responsibility for the performance or potential
damage caused by the use of such additives.
