• Ensure that you use Perkins Advanced Efficiency
Fuel Filters. Change your fuel filters per
recommended service requirements or as needed.
• Drain your water separators daily.
• Drain your fuel tanks of sediment and water per
the Operation and Maintenance Manual
instructions.
• Install and maintain a properly designed bulk filter
/ coalescer filtration system. Continuous bulk
filtration systems may be required to ensure that
dispensed fuel meets the cleanliness target.
Consult your Perkins distributor for availability of
bulk filtration products.
• Centrifugal filters may need to be used as a pre-
filter with fuel that is severely contaminated with
gross amounts of water and/or large particulate
contaminants. Centrifugal filters can effectively
remove large contaminants. Centrifugal filters may
not be able to remove the small abrasive particles
required to achieve the recommended "ISO"
cleanliness level. Bulk filter / coalescers are
necessary as a final filter to achieve the
recommended cleanliness level.
• Install desiccant type breathers of 4 µm or less
absolute efficiency with the ability to remove water
on bulk storage tanks.
• Follow proper practices of fuel transportation.
Filtration from the storage tank to the application
promotes the delivery of clean fuel. Fuel filtration
can be installed at each transport stage to keep
the fuel clean.
• Cover, protect, and ensure cleanliness of all
connection hoses, fittings, and dispensing
nozzles.
Consult your local Perkins distributor for additional
information on Perkins designed and produced
filtration products.
Renewable and Alternative Fuels
Perkins supports development and use of renewable
fuels through sustainability initiatives. In recent years
various forms of renewable and alternative
(synthetic) diesel fuels have started to emerge.
Synthetic diesel fuels are produced by gasification of
various feedstock and then synthesis to liquid to
obtain paraffinic diesel fuel. Based on the feedstock
used these fuels are commonly referred to as
Biomass to liquid (BTL), Gas to liquid (GTL) and Coal
to liquid (CTL). Hydrotreating of vegetable oils and
animal fats is another emerging process for
production of bio based diesel fuel called
Hydrotreated Vegetable Oil (HVO).
BTL and HVO fuels are considered to be low carbon
fuels as they reduce carbon foot print compared to
fossil fuels and are commonly referred to as
renewable fuels. These fuels must not be confused
with biodiesel FAME which is fundamentally different
fuel and is discussed in a separate section in this
manual.
These paraffinic fuels have virtually no sulphur or
aromatics and have very high cetane numbers which
enable very clean burning and efficient engine
operation. Chemically these fuels are similar to diesel
fuel derived from petroleum and are therefore
suitable to use in diesel engines as a replacement or
blend stock with conventional diesel fuel. To be
acceptable renewable and alternative fuels must
meet latest edition of the paraffinic diesel fuel
specification "CENTS 15940". The fuel should also
meet requirements described in table 14 , Perkins
Specification for Distillate Diesel Fuel, EN590, or
latest ASTM D975 specification.
Ensure that the fuel has got appropriate cold flow
properties (cloud point and CFPP) for the minimum
statistical ambient temperature the engine is
expected to see in the operation. The Fuel must also
meet lubricity requirements as specified in the
lubricity section of the "Operation and Maintenance
Manual" Fluid Recommendations
