FUEL, LUBRICANTS, AND COOLANT
FUEL
Fuel Selection
The following properties are required of the diesel fuel:
Must be free from minute dust particles.
The sulphur content must not exceed 0.5% by volume. A
higher sulphur content fuel may cause sulphuric acid
corrosion in the cylinders of the engines.
NEVER mix kerosene, used engine oil, or residual fuels
with the diesel fuel.
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 Portable Power representative for more information.
Ash content not to exceed 0.01% by volume.
Carbon residue content not to exceed 0.35% by volume.
Less than 0.1% is preferred.
Total aromatics content should not exceed 35% by
volume. less than 30% is preferred.
PAH (polycyclic aromatic hydrocarbons) content should
be below 10% by volume.
Metal content of Na, Mg, Si, and AI should be equal to or
lower than 1 mass ppm. (Test analysis method
JPI-5S-44-95).
Lubricity: Wear mark of WS1.4 should be Max. 01018 in
(460 um) at HFRR test.
Diesel fuel should comply with the specifications listed in
the table below. The table lists several worldwide
specifications for diesel fuels.
Fuel Requirements
CAUTION
The fuel injection pump, injector or other parts of the
fuel system and engine can be damaged if you use
any fuel or fuel additive other than those specifically
recommended by Doosan.
If any fuel other than the one specified is used,
engine operation will be impaired. Engine failure or
malfunction resulting from use of such improper fuel
will not be warranted by Doosan.
To help avoid fuel system or engine damage, please read
the following:
Do not use diesel fuel which has been contaminated with
engine oil. Besides causing engine damage, such fuel
can also affect emission control. Before using any diesel
fuel, check with the fuel supplier to see if the fuel has
been mixed with engine oil.
Your engine is designed to use either Number 1-D or
Number 2-D diesel fuel. However, for better fuel
economy, use Number 2-D diesel fuel whenever
possible. At temperatures less than -7°C, (20°F), Number
2-D fuel may pose operating problems (see "Cold
Weather Operation" which follows). At colder
temperatures, use Number 1-D fuel (if available) or use a
"winterized" Number 2-D (a blend of Number 1-D and
Number 2-D). This blended fuel is usually called Number
2-D also, but can be used in colder temperatures than
Number 2-D fuel which has not been "winterized."
Check with the fuel supplier to be sure you get the
properly blended fuel.
CAUTION
Do not use home heating oil or gasoline in your
diesel engine; either may cause engine damage.
