1.2 Reference conditions

The output is available within a range of ambient conditions and coolant temperatures specified

in the chapter Technical Data. The required fuel quality for maximum output is specified in the

section Fuel characteristics. For ambient conditions or fuel qualities outside the specification,

the output may have to be reduced.

The specific fuel consumption is stated in the chapter Technical Data. The statement applies

to engines operating in ambient conditions according to ISO 15550:2002 (E).

100 kPatotal barometric pressure

25 °Cair temperature

30 %relative humidity

25 °Ccharge air coolant temperature

Correction factors for the fuel oil consumption in other ambient conditions are given in standard

ISO 15550:2002 (E).

1.3 Operation in inclined position (only for Marine Solutions

engines)

The engine is designed to ensure proper engine operation at inclination positions. Inclination

angle according to IACS requirement M46.2 (1982) (Rev.1 June 2002) - Main and auxiliary

machinery.

Max. inclination angles at which the engine will operate satisfactorily:
