High efficiency turbocharger
Consumption (SFOC) values, see example in
Fig. 2.07.01.
At part load running the lowest SFOC may be
obtained at 80% of the optimised power = 80%
of the specified MCR.
All engine types 50 and larger are as standard
fitted with high efficiency turbochargers, option:
4 59 104.
The high efficiency turbocharger is applied to
the engine in the basic design with the view to
obtaining the lowest possible Specific Fuel Oil
