The engine is the largest reciprocating engine in the world. The 14-cylinder version first entered commercial service in September 2006 aboard the Emma Mærsk . The design is similar to the older RTA96C engine, but with common rail technology (in place of traditional camshaft , chain gear , fuel pump and hydraulic actuator systems).
The class, each ship powered by a single HSD-Sulzer 9RTA84T-D delivering 50,220 brake horsepower (37,450 kW) at 76 rpm, [6] possesses a relatively high service speed (16.5 knots; 30.6 km/h laden, 17.5 knots; 32.4 km/h in ballast), which increases their earning capacity.
Sulzer marine engines were well engineered and so various trials in the early days of oil engines paid dividends. In 1910 there was an icebreaker tug equipped with a Sulzer diesel at Hamburg. The 4 cylinder two-stroke diesel engine gave an indicated 210 bhp and 9.75 knots, had a 1/3rd smaller engine room than the steam equivalent, and the ...
The Busch-Sulzer Bros. Diesel Engine Company was founded by Adolphus Busch of the Anheuser-Busch brewing company in 1911 as a joint venture with Sulzer Brothers of Switzerland. The company manufactured diesel engines until 1946. In 1897, Adolphus Busch acquired rights to build diesel engines in the United States, with Rudolph Diesel as a ...
Straight-seven engine with firing order 1-3-5-7-2-4-6. A straight-seven engine or inline-seven engine is a straight engine with seven cylinders. It is more common in marine applications because these engines are usually based on a modular design, with individual heads per cylinder.
However, Sulzer had 42 years of experience in locomotive design [1] and Sulzer plants had been used widely in the UK since the early 1930s. [note 3] Any doubt was resolved by the purchase contract stipulating that Sulzer Bros (London) Ltd would accept full responsibility for the design and performance of the completed locomotives.

The only straight-14 engine known to reach production is part of the Wärtsilä-Sulzer RTA96-C family of 6-cylinder to 14-cylinder two-stroke marine engines. This engine is used in the Emma Mærsk , which was the world's largest container ship when it was built in 2006.
Sulzer ZG9 was a pre-World War II opposed-piston two-stroke diesel engine by Sulzer. [1] [2] The engine was available with a choice of two, three and four cylinders (2ZG9, 3ZG9, 4ZG9); the two-cylinder version developed 120 bhp. It used a piston scavenge pump. This was mounted vertically above one rocker, driven by a bellcrank from the main ...
