Fuel System
General Information
Fuel quality is crucial for engine performance, engine life,
and satisfying emissions standards. This engine is
manufactured for use with standard fuel as specified by
international petroleum-related laws and the Clean Air
Conservation Act.
Fuel Specifications
To maintain optimal engine performance as well as the
durability and reliability of fuel system components, make sure
to use fuel which satisfies the following fuel specifications.
• Korea: Article 115 Schedule 33 "Ultra Low Sulfur Diesel"
of the Clean Air Conservation Act
• Europe: EN590:2013 AC:2014, EN16734:2016
• North America: ASTM D975-15C Grade 1D or 2D
• Japan: JIS K2204:2007 (lubricity ≤ 520 μm, FAME Max.
5%)
• China: GB252:2015 and GB19147:2013
• India: IS 1460 2005 Amm. 10 BS III or BS IV
• Brazil: ANP69/2014
• Russia: GOST R32511-2013 (excluding Articles 3 and 4)
Fuel filter
The fuel filter consists of a primary and secondary filter; the
primary filter serves to filter out water and large particles of
foreign matter, while the secondary filter is used to filter out
smaller particles of foreign matter.
Bleeding Fuel Delivery Lines
To bleed the air in the fuel line, unscrew the hollow screw on
the fuel delivery pipe on top of the engine's high-pressure
pump mounting fixture; then, use a hand priming pump to
remove the air in the fuel line.
Fuel Tank
The fuel tank must be able to store fuel cleanly and safely
and must be structured so as not to affect the components of
the engine injection system.
Fuel Lines Connected to the Engine
Since the fuel lines connecting the engine and the fuel tank
must be flexible enough to withstand vibrations while the
engine is running, it is recommended to use hoses.
Hand Priming Pump and Connecting Adapter
A hand priming pump and two piping connecting adapters
are provided as separate accessories along with the engine.
Primary Fuel Filter, Connecting Adapter, Fuel
Heater, Service Tool
A primary fuel filter, two piping connecting adapters, fuel
heaters, and a service tool are provided as separate
accessories along with the engine.
• Only use clean fuel with the specified grade. Using
imitation or unspecified fuel may cause severe faults
in the engine.
• When fuel needs to be refilled, make sure to add fuel
while the engine is stopped.
• Failing to check the fuel filter periodically and drain
the water in the fuel filter causes moisture to enter
the engine fuel system, leading to severe faults in the
fuel injection pump, fuel injection pipe, common rail,
and injectors. In addition, the performance of the fuel
filter may be degraded or the filter may be damaged.
• When draining water from the fuel filter, fuel may be
drained as well. Fuel is a highly flammable
substance. Hence, smoking or using an open flame
near the engine may cause a fire.
• Only use clean fuel with the specified grade. Using
imitation or unspecified fuel may cause water to
accumulate in the fuel filter.
• If water is not drained from the fuel filter when the fuel
filter warning light is turned on, moisture may enter
the fuel system and cause the engine to turn off.
• New fuel filters must not contain any fuel when they
are installed. Do not fill a new fuel filter with fuel from
an old fuel filter or fuel in the fuel tank.
