The Rolls-Royce Bergen lean-burn gas engine is an advanced, clean and efficient unit that meets the most stringent demands for environmentally conscious electrical power generation systems.
It has undergone progressive technical development since its arrival in the power generation marketplace in the early 1990s. Today, the advantages provided by its lean-burn combustion using pre-chamber ignition maintain the engine’s position as the class leader in a worldwide market that increasingly demands high efficiency processes using environmentally friendly fuels.
The latest version, the KV-G4, producing between 2400 and 3640kW in 12, 16 and 18 cylinder versions, has changed the modern gas engine business by achieving higher efficiency compared with earlier spark-ignited gas engines, while also bringing down Nox emissions to new reduced levels.
Technical development has created one of the most cost-efficient engines available, with an output of 200kW of electrical power per cylinder at an efficiency of more than 46 per cent. These developments exploit advances in control and monitoring technology, both electronically and in terms of hardware.
The KV-G4 is ideally suited to today’s CHP market and is backed by the world’s finest pedigree of power – the experience of Rolls-Royce.
