Rolls-Royce Bergen C series

The Bergen C liquid fuel series is a compact reciprocating internal combustion engine manufactured by Rolls-Royce plc.

Design Duties

Capable of running on heavy fuel oil, it has been designed for genset and marine propulsion duties for powers from 1440 to 2700 kW.
The Bergen C liquid fuel series engines have 250mm bore 330mm stroke, running at 900/1000rpm or 720/750rpm.
It is available in 6, 8 and 9 cylinder in-line versions.
Features and benefits:

Power dense, 220/300 kW/cyl
Brake Mean effective pressure 22.6 – 24.7bar
Specific fuel consumption 182-186 g/kWh
High availability, designed for long service intervals, condition based maintenance
Cylinder unit replaced as a single unit

The Bergen C engine takes advantage of an advanced thermodynamic cycle, based on high compression ratio, optimised valve timing, high charge air pressure and late and fast combustion. This ensures good trade-off between fuel consumption, nitrous oxide emissions and particulates.

Dry Masses

The Bergen C engines have dry masses between 18000 and 25000 kg depending on the number of cylinders.
