PSA TU engine
Encyclopedia
The PSA TU engine is a family of small four-cylinder engines used in the Peugeot
and Citroën
range of cars. It was introduced in 1986 with the Citroën AX
, replacing the X family
, although it shared many components with its predecessor. The TU is available in either petrol or a non-turbo Diesel
variants, the latter called TUD.
The TU engine is/was used in the following cars:
Citroën: AX, Saxo, C2, C3, BX, ZX, Xsara, C15, Nemo and Berlingo. Peugeot: 106, 205, 206, 207, 309, 306, 307, 405, Bipper, Partner and Hoggar.
The TUD engine was only used in 8 cars of which 4 were non-PSA models:
the Citroën AX, Citroën Saxo, Peugeot 106, Rover Metro/100-series, Nissan Micra, Maruti Suzuki Zen D/Di and Maruti Suzuki Esteem D/Di and ikco samand.

In its early years, it was available with either a single or double barrel carburetor
, with fuel injection introduced in 1990 for the AX GTI and 106 XSi, capable of delivering 100 PS (73.5 kW) at 6600 rpm. The carburated versions gave way to fuel injection in 1992, while the sports version was retired in 1996.

TUD
The TUD was the diesel variant. It initially used the cylinder casings of the TU3 (and was thus called TUD3), but in 1992 displacement was increased to 1527 cc, with a bore of 77 mm and a stroke of 82 mm, the engine being renamed TUD5. It was available only with an injection pump (available in both Bosch and Lucas variants). Besides a number of applications in the PSA Group's supermini models (AX, Saxo, 106), it was sold to other automakers who did not possess small Diesel engines. It was used in the Rover MetroRover Metro
