PSA TUD engine

The PSA TUD is the diesel version of the TU family of small four-cylinder in-line engines, used in various Peugeot and Citroën cars and, because PSA sold it to makers without a small diesel of their own, in vehicles of other brands too. Peugeot first took the cylinder block of the 1,360 cc TU3, with a 75 mm bore and 77 mm stroke, and named the diesel the TUD3. In 1994 the displacement was raised to 1,527 cc with a 77 mm bore and 82 mm stroke, and the engine was renamed the TUD5. It was offered with a Bosch or Lucas injection pump and, by one reference, was built from 1993 until production ended in 1998. Besides the Peugeot 106 and the Citroën AX and Saxo, it went into the Nissan Micra, the Maruti Suzuki Zen D and Esteem D, the IKCO Samand, the Proton Tiara, the Rover 114D and Mini Metro 100 and the Lada Samara. In the type code the letters TUD mark a diesel and the first digit gives the capacity in hundreds of cubic centimetres.
