The Wärtsilä 32GD has been developed to set new standards in the market for high performance, fuel-flexible engines. The Wärtsilä 32GD is a four-stroke, gas-diesel engine, which means that the engine can run on either gas or fuel oil according to the diesel cycle. Switching from one fuel to the other can be done under all operating conditions.
The Wärtsilä 32GD covers a power range of 2520 – 8400 kW. The engine runs at 720 or 750 rpm for use with 50 or 60 Hz generators and produces 405 – 420 kW per cylinder.
The main features of the Wärtsilä 32GD are:
• Low-NOX combustion
• Reliability and low maintenance costs
• Integrated monitoring and control or basic
automation system
• Ergonomic interface
• Minimized consumables
• Unique fuel flexibility
