Gas engine, Bergen C26:33
Excellent fuel economy and lowest emissions over the full operating range.
Powering the future
The Rolls-Royce Bergen C-series has a simple and robust design with a reduced number of components. A lean-burn engine operates on the Otto cycle with mixture compression and an external ignition source. A rich gas / air mix in a pre-combustion chamber is ignited and forms a strong ignition source for the very lean mixture in the cylinder for knock-free combustion. This allows the cylinder power to be greatly increased with high efficiency and reduce emissions.
The engine platform offers 243 - 270 kW per cylinder in a compact and modern design. In-line engines are offered in 6, 8 and 9 cylinder configuration spanning a power range from 1,460 kW to 2,430 kW.
