W"artsil"a 46DF

  • Cylinder bore 460 mm
  • Piston stroke 580 mm
  • Cylinder output 1045/1145 kW/cyl
  • Engine speed 600 rpm
  • Mean effective pressure 21.7, 23.8 bar

Fuel flexibility

W"artsil"a’s proven dual-fuel technology enables owners and operators to choose both gas and liquid fuel, and switch between the two according to cost, availability, and local environmental regulations.

The switch between fuel types is made without loss of power or speed. The engine automation adapts automatically to the relevant fuel selection, both in normal and emergency modes.

In gas mode, the natural gas is fed to the engine at low pressure. This facilitates a simpler and space saving engine room configuration, while providing easier and faster maintenance activities.

The engine’s gas piping is double-walled as standard, and the advanced integrated automation system enables enhanced safety and local monitoring. This leads to safer and more reliable operations, under all conditions.The complete built-in automation minimizes the need for external controls, thus saving engine control room space.
