SFOC for High Efficiency Turbochargers
Fig. 2.07.01: Example of part load SFOC curves for high efficiency turbochargers, valid for fuel oil and
gas fuel operation, respectively
178 64 54-9.0
For standard high load optimised ME/ME-C
engines operating on fuel oil the lowest SFOC at
part-load running may be obtained at 70% of the
specified MCR. However, for -GI engines operat-
ing on gas fuel the SFOC may be further reduced
on part load operation.
For more information visit: www.marine.man.eu →
’Two-Stroke’ → ’Turbocharger Selection’.
All -GI engines are as standard fitted with high
efficiency turbochargers, option: 4 59 104, and
can as standard only be high load optimised.
The high efficiency turbocharger is applied to the
engine in the basic design with the view to ob-
taining the lowest possible related Specific Fuel
Oil Consumption (SFOC) values, see example in
Fig. 2.07.01.
