A V14 engine is a V engine with 14 cylinders mounted on the crankcase in two banks of seven cylinders. It is a very rare layout, used almost exclusively on large medium-speed diesel engines used for power generation and marine propulsion.
Marine use
MAN B&W offers V14 layout for its 32/40, 32/44CR, 48/60CR, 49/60DF, and 51/60DF engines, with outputs ranging from 7,000 to 18,200 kW (9,400 to 24,400 hp). [1] MAN V14 engines have been installed on cruise ships such as the Explorer Dream and Norwegian Spirit, both of which have 14V48/60 engines producing 14,700 kW (19,700 hp) each, [2] and on some cargo vessels. However, other major manufacturers do not normally offer medium-speed engines in the V14 configuration.
Wärtsilä has only recently begun to offer V14 versions of its latest engine models, the 31, 46F, and 46DF. [3]
In the past, V14 engines have also been offered by other manufacturers. Between 1982 and 1987 nineteen SA-15 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.
