Wartsila W34 Dual Fuel Generator Engine | High-Efficiency Power Solution
Cylinder Configurations
Available in 12V, 16V, and 20V setups for 50 Hz (750 rpm) or 60 Hz (720 rpm) grids.
Bore measures 340 mm with a 400 mm stroke, yielding 36.3 L displacement per cylinder.
The Wartsila 34DF dual fuel generator engine, also called the Wartsila W34, can provide reliable power in 12V, 16V, and 20V variants. The Wartsila 32 platform has been around since the 1990s and is known for its reliability. It allows for smooth changeover between natural gas, LFO, and HFO for energy security. Its lean-burn design lowers NOx emissions while keeping efficiency high, up to 48.6% in gas mode.
This engine is great for maritime propulsion, auxiliary power, and stationary power plants that require to be able to use many types of fuel.
