A V14 engine is a V engine with 14 cylinders mounted on the crankcase in two banks of seven cylinders. A relatively uncommon cylinder configuration, the V14 layout has been used on large medium-speed diesel engines used for power generation and marine propulsion.

Marine use[edit]

MAN B&W offers V14 layout for all its current medium-speed diesel engines except V28-33D and L58-64, with output ranging from 7,000 to 16,800 kW (9,400 to 22,500 hp).[1] MAN V14 engines have been installed for example on SuperStar Virgo and Norwegian Spirit, both of which are powered by four 14V48/60 generating sets producing 14,700 kW (19,700 hp) each.[2] However, other major manufacturers, such as Wärtsilä, do not offer medium-speed engines in V14 configuration.[3]

In the past V14 engines have also been offered by other manufacturers. In 1982–1987 nineteen SA-15 class arctic cargo ships were built with two 14-cylinder Wärtsilä-Sulzer 14ZV40/48 engines producing 7,700 kW (10,300 hp).[4] SEMT Pielstick, nowadays part of MAN B&W, also produced four-stroke engines with 14 cylinders in V-configuration (14PC2[5] and 14PC4[6]). They were used for example on RFA Bayleaf, a Leaf-class support tanker of the Royal Fleet Auxiliary.

Automotive use[edit]

V14 engines have not been used in production cars, although a 4.5 L (275 cu in) 14-cylinder engine was, according to chief designer Gordon Murray, considered for the McLaren F1.[7]
