Wärtsilä 64 is a type family of diesel engines from the Finnish company Wärtsilä . In terms of displacement and power, the Wärtsilä 64 is the largest four-stroke diesel engine in the world and it was also the first four-stroke engine with an efficiency of over 50%. It is designed as a medium- speed runner for cargo ships and is suitable for operation with residual oils and diesel engine fuel.

The first prototype test of the engine took place in September 1996, the first units were delivered to the customer in autumn 1997. The engines are manufactured in Trieste . Originally, the cylinder output was supposed to be 2.01 MW, this value was later increased to 2.15 MW / cylinder by increasing the torque. The engine is offered as an in- line engine with six, seven, eight or nine cylinders, with an output of 12.9 MW, 15.05 MW, 17.2 MW or 19.35 MW. The nominal speed is 333.3 min −1 , the mean piston speed 10 m / s.
