MAN has announced the launch of its latest in the line of its diesel engines, the 26 MW MAN 20V45/60. The company said that the model, in addition to having higher power than its predecessor, also has a considerably reduced fuel consumption.

Wayne Jones, Chief Sales Officer of MAN Diesel & Turbo, said: “The 20V45/60 expands the current performance range of MAN’s 4x family of diesel engines by more than 4 MW, while offering a best-in-class fuel efficiency of over 50 per cent, allowing our customers to save both investment and operational costs.

Alexander Stöckler, Global Head of Sales for the power plants business at MAN Diesel & Turbo, said that the 20V45/60 was a perfect fit for power generation in remote locations and islands where a gas supply is not available. He said that it is able to withstand extreme site conditions such as high ambient temperatures and high altitudes, making the engine an excellent solution for captive power applications in climactically-demanding locations. He said: “The two-stage turbocharging prevents derating even at 2500 metres above sea level, and the engine shows no decrease in output, even in ambient temperatures of up to 53°C.”

Dr Gunnar Stiesch, Head of Engineering Engines at MAN Diesel & Turbo, said that the new engine utilises two-stage turbocharging, which achieves excellent efficiency as a result of a low-pressure and a high-pressure turbocharger arranged in series. He said that: “Operators profit from maximised peak pressure and optimal utilisation of the Miller Cycle.”

The new engine uses the company’s latest generation digital Safety and Control System, SaCoS 5000. Stiesch said that SaCoS 5000 offers unprecedented data availability and optimised alarm visualisation and diagnosis. “Thanks to the new SaCoS, the MAN 45/60 is not only online-ready, but also equipped for the digital future of power generation.”

Gas and dual-fuel versions of the engine are currently under preparation.
