X92DF-M-1.0

X92DF-M-1.0

The biggest two-stroke dual-fuel engine, designed for modern large and ultra large container vessels.

This 920mm bore engine has the output in the 24,420 to 77,400kW range, and it comes in 6–12 cylinder configurations.

X-DF for methanol and ethanol WinGD’s methanol-fuelled engines can now be adapted and certified for ethanol fuel, with the first ethanol fuelled vessels expected to enter service in 2027.

With the first methanol-fuelled engines delivered in 2025 and the first ethanol-fuelled engines available for order now, X-DF-M/E enables deep-sea ship owners and operators to choose from a range of fuels including carbon-neutral green methanol and attractively priced bio-ethanol.
