Tuning
Related to the contract the engine has one of the tuning options that follow (refer to
•
Standard tuning
The standard tuning gives a good fuel consumption over the full engine power range.
•
Delta tuning
The delta tuning decreases the fuel consumption below 90% engine power compared to
standard tuning. But it increases the fuel consumption between 90% and 100% of engine
power.
•
Delta bypass tuning
The delta bypass tuning decreases the fuel consumption below 50% engine power
compared to delta tuning. For more than 50% of engine power the fuel consumption is the
same as delta tuning, but the steam production is increased.
•
Low-load tuning
The low-load tuning decreases the fuel consumption below 75% engine power compared
to delta tuning or delta bypass tuning. But it increases the fuel consumption between 90%
and 100% of engine power compared to delta tuning.
