Straight-seven engine
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.
Marine engines
Straight-seven engines produced for marine usage include:
- Wärtsilä-Sulzer RTA96-C two-stroke crosshead diesel engine[1]
- Wärtsilä 32 trunk piston engines[2]
- MAN Diesel IMO two-stroke crosshead diesel engine[3]
- Burmeister & Wain 722VU37 two-stroke diesel engine (commenced 1937, used in the Danish Havmanden-class submarines
- Sulzer 7QD42 diesel engine (1939-1940, used in the Dutch O 21-class submarines).[4]
Land use
The AGCO Sisu 98HD is a straight-seven diesel engine that was released in 2008.[5] Intended for farming machinery, the engine shares various components with the company's straight-six engine.[6]
