DIESEL FUEL
Diesel Fuel Specifications
Diesel fuel should comply with the following specifications. The table
lists several worldwide specifications for diesel fuels.
ADDITIONAL TECHNICAL FUEL REQUIREMENTS
• The fuel cetane number should be equal to 45 or higher.
• The sulphur content must riot exceed 0.05% by volume. Less than
0.05% is preferred.
For electronically controlled engines 4TNV84T-Z, 4TNV98-2,
4TNV98-E, and 4TNV98T-2, it is mandatory to use fuel that does
not contain 0.05% or more sulphur content.
In general, using a high sulphur fuel may possible result in
corrosion inside the cylinder.
• Bio-Diesel fuels. See Bio-Diesel Fuels.
• NEVER mix kerosene. used engine oil, or residual fuels with the
diesel fuel.
• The water and sediment in the fuel should not exceed 0.05% by
volume.
• Keep the fuel tank and fuel-handling equipment clean at all times.
• Poor quality fuel can reduce engine performance and / or cause
engine damage.
• Fuel additives are not recommended. Some fuel additives may
cause poor engine performance. Consult your Yanmar
representative for more information.
• The ash content must not exceed 0.01% by volume.
• The carbon residue content must not exceed 0.35% by volume.
Less than 0.1% is preferred.
• The total aromatics content should not exceed 35% by volume.
Less than 30% is preferred.
• The PAH (polycyclic aromatic hydrocarbons) content should be
below 10% by volume.
• The metal content of Na, Mg, Si, and Al should be equal to or lower
than 1 mass ppm. (Test analysis method JPI-5S-44-95)
• Lubricity: The wear mark of WS1.4 should be Max. 0.018 in (460 m)
at HFRR test.
BIO-DIESEL FUELS
In Europe and in the United States. as well as some other countries,
non-mineral oil based fuel resources such as RME (Rapeseed Methyl
Ester) and SOME (Soybean Methyl Ester), collectively known as
FAME (Fatty Acid Methyl Esters), are being used as extenders for
mineral oil derived diesel fuels.
Yanmar approves the use of bio-diesel fuels that do not exceed a blend
of 5% (by volume) of FAME with 95% (by volume) of approved mineral
oil derived diesel fuel. Such bi-diesel fuels are known in the
marketplace as B5 diesel fuels.
These B5 diesel fuels must meet certain requirements.
1 The bio-fuels must meet the minimum specifications for the country
in which they are used.
• In Europe, bio-diesel fuels must comply with the European
Standard EN1 4214.
• In the United States, bio-diesel fuels must comply with the
American Standard ASTM D6751.
2 Bio-fuels should be purchased only from recognized and authorized
diesel fuel suppliers.
