The Emma Mærsk is powered by Wärtsilä engines

Wärtsilä engines are mainly used for marine propulsion and for electricity generation. The engines which Wärtsilä produces range from the 4L20, a four-stroke, medium-speed engine producing 720 kW (980 HP), to the Wärtsilä-Sulzer RT-flex96-C two-stroke diesel engine series which, in 2006, was reported as being one of the most powerful yet most compact prime-movers in the world. This model has a cylinder bore of 960 mm (37.8 in) and stroke of 2500 mm (98.4 in). The largest version produces up to 80,080 kW (107,400 HP) in the 14-cylinder configuration. These engines are used to propel large container ships, such as those of the A. P. Moller-Maersk Group. The vessels are known as the E-class ships; Emma Maersk was the first.

Wärtsilä produces a full line of four-stroke medium-speed engines, many of which are multi-fuel capable (diesel fuel, heavy fuel oil, vegetable oils, and natural gas) ranging up to the 20V46F which produces 23,000 kW (30,820 HP) operating at 600 RPM.

Wärtsilä also offers a full line of two-stroke, low-speed engines, ranging from approximately 3860 kW (5250 HP) up to 80,080 kW (107,400 HP). The two-stroke units are compact, and generate excellent power for their weight. However, on a per-horsepower basis, they also produce substantially more emissions than four-stroke units. [2]
