A straight-14 engine or inline-14 engine is a fourteen-cylinder internal combustion engine with all fourteen cylinders mounted in a straight line along the crankcase. A straight-14 is a very long engine, and therefore only suitable for marine installations in large ships.

Examples[edit]

The only engine of this type known to have been built is a member of the Wärtsilä-Sulzer RTA96-C family. It is the world's most powerful combustion engine and is mounted in Emma Mærsk, the world's largest container ship. It is of two-stroke diesel engine configuration. The engine became well known due to photos taken at the Aioi Works in Japan, which subsequently spread through blogs.

The 14-cylinder version of this modular engine produces 80,080 kilowatts (107,390 hp) and displaces 1,556,000 cubic inches (25,500 L), with a 38-inch (970 mm) cylinder bore and 98-inch (2,500 mm) piston stroke. The engine is 89 feet (27.1 m) long, 44 ft (13.4 m) high, and weighs 2,300 tonnes (2,264 long tons; 2,535 short tons).

If built, the 14-cylinder variant of the MAN B&W K108ME-C would be even larger at nearly 33 metres (108 ft) long, and over 2,800 tonnes (2,800 long tons; 3,100 short tons), and more powerful at 97,300 kilowatts (130,500 hp).
