1. Main Data and OutputsWärtsilä 46F Product Guide
1.2 Reference conditions
The output is available up to 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 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
Max. inclination angles at which the engine will operate satisfactorily.
15°
●Permanent athwart ship inclinations
22.5°
●Temporary athwart ship inclinations
10°
●Permanent fore-and-aft inclinations
