1 Engine Summary
1.3 Fuel operating modes
X62DF-S2.0
1.3.2 Operation in diesel mode
In general, diesel mode is always available. If the gas system fails or the engine
output in gas operation mode is insufficient, the diesel mode provides opera-
tional flexibility and a fail-safe.
The main fuel injectors inject the main fuel, while the pilot fuel micro-injectors
remain in operation at a reduced injection rate to avoid clogging of the nozzles
(approximately 0.5 % of total fuel consumption in diesel mode). The main fuel
can be changed over from either MDO or MGO to HFO. Before changing back
to gas mode, the main fuel must be changed back to diesel oil (see section 1.3.4,
 1-17).
For engine operation on distillate fuels, see the following Concept Guidance
(DG 9723), as provided on the WinGD webpage:
Operation on distillate fuels
The Flex system
The engine is equipped with WinGD’s common-rail injection system which en-
ables flexible fuel injection.
