Ford Dorset/Dover engine

The Ford Dorset and Dover engines are a series of inline diesel engines that Ford used in vehicles including the Ford Cargo truck between 1981 and 1993, and that have stayed in production since for marine and industrial uses. Lehman Brothers of New Jersey is the best known of the firms that marinized them. The two variants share displacements: a 4,146 cc four-cylinder was offered, and the larger 5,942 cc and 6,218 cc sizes were six-cylinder engines. The Dover 5.9 is sometimes called a 6.0, even by Ford, which named the turbocharged version the 360TC against the naturally aspirated 359; the 360TC was built to closer clearances. The Dover has higher specification parts than the Dorset, with an aluminium rather than pressed steel manifold, straight-cut gears and larger ports in the head, and the engine codes are 2711 for the Dorset and 2722E for the Dover. The Dorset was built at Ford Dagenham in Essex, England, and the Ford Otosan Ecotorq family later replaced the series in the Cargo.
