Wärtsilä Vasa

[1] The series comprises three models, the Vasa 22, 32, and 46, with the number denoting the bore size of the engine.

Vasa engines are turbocharged, non-reversible, and utilize a direct fuel injection system.

This provides the engine the initial rotation force needed to achieve combustion.

Treated fresh water is used for cooling of the cylinder, charge air, turbocharger, and oil.

The freshwater temperature is closely regulated with a thermostatic valve to achieve optimum efficiency.

During operation, an engine will automatically cease injection if all preset conditions are not met.

[3] These engines are primarily used for power generation and diesel-electric propulsion plants.

The engines were used to provide electrical power for both propulsion and auxiliary services.
