2.3.1.1
For preheated engine
Fig 2-5
Nominal start-up time
NOTE
Continuous prelubrication of the engine can be done when the engine is in stop
mode if shorter start-up time is required.
2.4
Low air temperature
The minimum inlet air temperature of 5°C applies, when the inlet air is taken from the engine
room.
Engines can run in colder conditions at high loads (suction air lower than 5°C) provided that
special provisions are considered to prevent too low HT-water temperature and T/C surge.
For start, idling and low load operations (Ch 2.3), suction air temperature shall be maintained
at 5°C.
If necessary, the preheating arrangement can be designed to heat the running engine (capacity
to be checked).
For further guidelines, see chapter Combustion air system design.
