The PSA XU is a family of internal combustion engines used in Citroën and Peugeot automobiles. It became the dominant mid-size engine in Peugeot and Citroën products through the 1980s and 1990s.
The XU design was introduced in 1981 with the Peugeot 305. It was a SOHC or DOHC straight-4 design with two or four valves per cylinder, using petrol as fuel. It was applied transversely in front wheel drive vehicles only, tilted by 30°. Displacement ranged between 1580 and 1998 cc, and all production XU gasoline engines had a bore of 83 mm (3.3 in) or 86 mm (3.4 in). The engine uses in all models aluminium cylinder head. All models blocks are made, except XU10, in cast aluminium alloy with removable cast iron wet cylinder liners. XU10 blocks are made in cast iron, with bores machined directly in the block, without removable cylinder liners. Its first Citroën application was on the Citroën BX in 1983, where it appeared in 1580cc format.
The XU was replaced by the more modern EW/DW family.
XU5
The XU5 had a displacement of 1.6 L (1580 cc), with a bore of 83 mm (3.3 in) and a stroke of 73 mm (2.9 in). All XU5 engines were SOHC 2-valve per cylinder designs. It used either a single or double-barrel carburetor or fuel injection, depending on model. Output ranged from 80–115 PS (79–113 hp/59–85 kW).
