Augsburg, 30 January 2006. The MAN B&W Diesel Group is launching a new four-stroke engine onto the market that not only burns both gas and MDO (Marine Diesel Oil), but can also run long-term on pure HFO (Heavy Fuel Oil). This flexibility meets and even exceeds all requirements from the marine as well as the stationary market.

The 51/60DF (Dual Fuel) engine is based on the well-known 48/60B range, tried and tested in both marine and stationary applications. Its technology benefits from the experience that MAN B&W Diesel has gained over decades of working with smaller dual-fuel engines, most recently with the 32/40DF range.

The 51/60DF is currently the largest four-stroke gas engine on the market and is to be incorporated in all its versions into the MAN B&W Diesel product portfolio in a spectrum ranging from the 6-cylinder in-line engine to the 18-cylinder V-engine. A special common rail pilot oil injection system makes the engine exceptionally environmentally friendly. The available engine power ranges from 6,000 to 18,000 kW.

Being the most powerful dual-fuel four-stroke engine in its class, the 51/60DF is not only aimed at the LNG tanker market, but is also ideal for base load electricity generation in power stations with a good gas connection. After extensive tests on our test bed, the first series-produced engines will be dispatched from mid-2007.
