From gas to liquid fuel and back – fast

MAN 51/60DF

The 51/60DF engine from MAN Diesel & Turbo is a dual fuel engine that converts liquid fuel (diesel operation) or natural gas into electrical power efficiently and with low emissions.

The engine is able to switch smoothly and seamlessly from gas to liquid fuel operation (and vice versa) at full load without any output and speed fluctuations. This feature makes it possible to use the engine in many different applications with a variety of fuels.

The engine delivers maximum output combined with maximum flexibility and reliability. The 51/60DF supplies an electrical genset output range of 8,847 kW up to 17,766 kW.
