MAN L21/31(G/E)
Dual Fuel (DF) Engines  

Dual fuel engines from MAN Diesel & Turbo run efficiently on liquid fuels or natural gas with very low emissions compliant to IMO limits. The possibility to switch over seamlessly from gas to diesel operation and vice versa provides full flexibility in multiple applications.
 
All dual fuel engines can run on natural gas with a methane number higher than 80 without adjustments. For lower methane numbers, MAN Diesel & Turbo can deliver well-adapted solutions. The optimized combustion chamber ensures very low fuel consumption in both operational modes. 
 

Diesel Oil (D) Engines
The V28/33D features very favourable ratios of power-to-weight and power-to-installation space. Its combination of low fuel consumption, low emissions and reduced life cycle costs makes this engine the ideal solution for propulsion in high speed ferries, naval and offshore patrol vessels. The V28/33D engine operates on distillates according to ISO8217 DMA or equivalent fuel types.
