Sulzer RT-flex. RT-flex sizes
The hardware in the RT-flex system is being developed in four principal sizes for the six engine types currently in the programme. The six RT-flex engine types cover a power range of 8100 to 80080 kW (11000 to 108920 BHP).
This illustrates one of the advantages of the common-rail system in that hardware is standardised for groups of engine types, not just for the various cylinder numbers.
