1.2 Reference conditions
The output is available up to a charge air coolant temperature of max. 38°C and an air
temperature of max. 45°C. For higher temperatures, the output has to be reduced according
to the formula stated in ISO 3046-1:2002 (E).
The specific fuel oil consumption is stated in the chapter Technical data. The stated specific
fuel oil consumption applies to engines with engine driven pumps, operating in ambient
conditions according to ISO 15550:2002 (E). The ISO standard reference conditions are:
100 kPa total barometric pressure
25°C air temperature
30% relative humidity
25°C charge air coolant temperature
Correction factors for the fuel oil consumption in other ambient conditions are given in standard
ISO 3046-1:2002.
1.3 Operation in inclined position
Max. inclination angles at which the engine will operate satisfactorily.

1.4 Arctic package description
When a vessel is operating in cold ambient air conditions and the combustion air to the engine
is taken directly from the outside air, the combustion air temperature and thus also the density
is outside the normal range specified for the engine operation. Special arrangements are
needed to ensure correct engine operation both at high and at low engine loading conditions.
Read more about the special arrangements in chapters Combustion air system design in arctic
conditions, Cooling water system for arctic conditions and Lubricating oil system in arctic
conditions.
