Our dual fuel engines: Delivering high performance, efficiency and versatility

MAN 51/60DF

This dual fuel engine converts diesel or natural gas efficiently, and can switch from one fuel to another without any fluctuations in speed or output. It's also possible to easily upgrade our MAN 51/60 engine to dual fuel capability if necessary. Also available with
two-stage turbocharging.

  • Engine speed: 500/514 rpm
  • Frequency: 50/60 Hz
  • Up to 20,700 kWm

MAN 28/32S DF

Based on the MAN 28/32H workhorse, the MAN 28/32S DF can switch effortlessly from diesel fuel to gas and vice versa.

  • Engine speed: 720/750 rpm
  • Frequency: 60/50 Hz
  • Up to 1,800 kWm

MAN 23/30S DF

MAN Energy Solutions offers a range of reliable dual fuel engines to give operators the flexibility they need to react to changing environmental regulations and fuel availability.

Making the most of all fuel sources

MAN Energy Solutions designs dual fuel engines to achieve the same high performance and efficiency – whichever fuel may be available.  

The main advantage of dual fuel technology is fuel flexibility. This makes it possible to take advantage of the low cost and superior environmental benefits offered by gas. If the supply of gas fuel is interrupted, the engine can continue operating using liquid fuel. In addition to natural gas, our dual fuel engines can also run on liquid biofuel or distillates like marine diesel oil (MDO), marine gas oil (MGO), crude oil and heavy fuel oil (HFO). Dual fuel engines from MAN Energy Solutions are known for their reliability, efficiency, performance and the ability to switch between fuel sources. And if you already have one of our liquid fuel engines, it's easy to upgrade to dual fuel capability to meet changing needs.
