Rolls-Royce Bergen C series
Encyclopedia
The Bergen C liquid fuel series is a compact reciprocating internal combustion engine
manufactured by Rolls-Royce plc
.
, it has been designed for genset (the prime mover in electrical generation applications) 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:
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
(Nox) emissions and particulates.
Internal combustion engine
The internal combustion engine is an engine in which the combustion of a fuel occurs with an oxidizer in a combustion chamber. In an internal combustion engine, the expansion of the high-temperature and high -pressure gases produced by combustion apply direct force to some component of the engine...

Design Duties
Capable of running on heavy fuel oilFuel oil
Fuel oil is a fraction obtained from petroleum distillation, either as a distillate or a residue. Broadly speaking, fuel oil is any liquid petroleum product that is burned in a furnace or boiler for the generation of heat or used in an engine for the generation of power, except oils having a flash...

Features and benefits:
- Power dense, 220/300 kW/cyl
- Brake Mean effective pressureMean effective pressureThe mean effective pressure is a quantity related to the operation of an reciprocating engine and is a valuable measure of an engine's capacity to do work that is independent of engine displacement. When quoted as an indicated mean effective pressure or imep , it may be thought of as the average...

Nitrous oxide
Nitrous oxide, commonly known as laughing gas or sweet air, is a chemical compound with the formula . It is an oxide of nitrogen. At room temperature, it is a colorless non-flammable gas, with a slightly sweet odor and taste. It is used in surgery and dentistry for its anesthetic and analgesic...
