1 Engine Summary
1.1 Engine capability and features
X62DF-S2.0
Certified Tier III:
Gas mode
In gas mode the main fuel is natural gas. The natural gas is injected into the en-
gine at low pressure. The gas fuel is ignited by injecting pilot fuel. The amount of
injected pilot fuel is less than 1 % of the total energy consumption of the engine.
Gas injection is hydraulically actuated and electronically controlled. Inde-
pendent micro-injectors and the pilot fuel system inject the pilot fuel. The pilot
fuel can be Marine Diesel Oil (MDO) or MGO.
Certified Tier II:
Diesel mode
The main fuel injectors inject the main fuel (HFO, MDO or MGO) in diesel
mode. To prevent clogging of the nozzles, the pilot fuel micro-injectors remain in
operation at a reduced injection rate which is approximately 0.5 % of the total
fuel consumption of the engine. The X-DF engine operates in diesel mode with
either residual marine fuel (HFO) or with marine distillate fuel (MDO or MGO)
which must be in accordance with the ISO 8217:2017 specification. The HFO
can have a maximum viscosity of 700 cSt. The MDO comprises either DMB or
DFB, while the MGO comprises either DMA, DFA, DMZ or DFZ, according to
the category definitions in the ISO 8217:2017 specification.
iCER diesel Tier III mode
The engine may be selected with the iCER diesel Tier III mode option. While the
engine is operating in iCER diesel Tier III mode,  1-14, the main fuel (MGO
only) is used in the same way as in the normal diesel mode operation. However,
with the iCER (see section 4.2,  4-4) active, the engine reaches Tier III compli-
ance without any additional exhaust gas treatment system such as Selective Cat-
alytic Reduction (SCR).
Control system
The WinGD Engine Control System (ECS) manages the key engine functions
such as gas admission, exhaust valve drives, engine starting and cylinder lubrica-
tion. The engine control system also ensures control of the fuel injection.
Compliance with
international codes
The WinGD X62DF-S2.0 must comply with the following international codes:
• “International Code for the Construction and Equipment of Ships Carrying
Liquefied Gases in Bulk (IGC Code)”
• “International Code of Safety for Ship Using Gases or Other Low-flash-
point Fuels (IGF Code)”
