Gas generating set, Bergen C26:33L

The C26:33-series engine is a simple and robust design with a reduced number of components.

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.

Key features

  • Compact and powerful
  • Exceptionally low emissions of of NOx, CO2, SOx and particulate
  • Low energy consumption
  • Service friendly
  • Optimum response at all engine load points (Variable Turbo Geometry)
  • Super silent resilient mounting
  • Table frequency
