PSA DJ/DK engine

The PSA DJ/DK is a family of inline-four diesel engines that the English Wikipedia list of PSA engines describes as derived from the XUD. The DJ engines were meant for installation in commercial vehicles, while the DK engines went into passenger cars. The list gives the DK5 as a 2.5 litre, 2,446 cc turbocharged engine. A second reference describes the DK5ATE, coded THY and built from 1994 to 2000, as fitted only to two flagship models, the Peugeot 605 and the Citroën XM, and as essentially a modification of the commercial DJ5TED engine. That unit has a cast iron block, an aluminium 12-valve head, a 92 mm bore and stroke, a prechamber fuel system, an intercooled turbocharger, hydraulic lifters and a timing belt, and is listed at 129 hp and 285 Nm.
