Peugeot Citroën PSA TU engine

Peugeot Citroën PSA TU engine

 The PSA -TU engines are a series of small four-cylinder in - line engines used in various Peugeot and Citroën cars. The engine was introduced in 1986 with the launch of the Citroën AX , replacing the X Series, with many components in common with its predecessor. The TU is available either as a gasoline or diesel version, which bears the name TUD for distinction. The performance of the TU engines ranges from 29 to 92 kW (40 to 125 hp). The gasoline versions have capacity of 954, 1124, 1294, 1360 or 1587 cc, the diesel 1360 or 1527 cc.

The TU engine is or was used in the following vehicles:

  • Peugeot : 106 , 205 , 206 , 207 , 309 , 306 , 307 , 405 , Bipper , Partners and Hoggar .
  • Citroën : AX , Saxo , C2 , C3 , C4 , BX , ZX , Xsara , C15 , Nemo and Berlingo .
  • Fiat : Fiorino .
  • Proton : Tiara .

Name, Code 

Each TU engine is identified with a version code, for example TU3MC (KDX) stamped on a riveted aluminum plaque.

The badge contains the following information:

  • The fuel used, which is indicated by the first two or three letters: TU (petrol) or TUD (diesel).
  • The first number indicates the hundredth position of the cubic capacity : TU3 thus stands for petrol engine 1 3 60 cc.

The remaining letters or numbers in the sequence give additional hints:

  • M indicates that the fuel of an electronic Monopoint - intake manifold with (single injector) is injected.
  • C shows an electronic ignition without distributor . ("Dormant" ignition system)
  • F indicates that the engine block is made of cast iron.
  • A is a change (A for "improved") of an earlier version.
  • S is a sporty variant with a higher performance than the base engine.
  • J indicates that the fuel is supplied via a multi-port electronic fuel injection system with four injectors (one per cylinder). J immediately followed by a 2 ("J2") shows two valves per cylinder (eight in total), followed by a 4 ( "D4" or "JP4" ), this indicates the presence of 16 valves (four per cylinder).
  • P stands for a controlled carburetor .
  • 2 or 0.2 shows a carburetor with two throttle valves .
  • 4 or 0.4 shows a double carburetor .
  • TR shows a version with a reduced compression ratio .
  • K means "without catalyst ".
  • Z means "with catalyst".

TU9

The TU 954 cc was the engine with the smallest displacement. Its bore is 70 mm with a stroke of 62 mm. There are five versions. Its power is 29 kW (40 hp), 33 kW (45 hp) or since the introduction of electronic fuel injection with catalyst 1992 37 kW (50 hp). He equipped the entry-level versions of the Citroën AX, the Peugeot 205, the Peugeot 106 and the Citroën Saxo. The normal compression ratio was 9.4. The production has been discontinued at Citroën Saxo and Peugeot 106 since the entry into force of the European emission standard Euro III on 1 January 2001.

TU1

The TU1 has a capacity of 1124 cc with a bore of 72 mm and a stroke of 69 mm. The power was initially 40.5 kW (55 hp), but with the introduction of the electronic injection and the catalytic converter in 1992, it was increased to 44 kW (60 hp). The introduction of multi-point injection led to compliance with the Euro 3 standard while maintaining power, with only a small increase in torque. This engine was since 2009, the entry-level model for Citroën C2 and C3 and the Peugeot 206th

TU24 

TU24 has a capacity of 1294 cc with a bore of 75 mm and a stroke of 73.2 mm. The performance was 70 kW (95 hp) for the Citroën AX Sport, as well as for the Peugeot 205 Rallye in a slightly more powerful version 76 kW (103 hp) with a shorter intake manifold for a direct air intake. A new version with electronic Magneti-Marelli injection and a 74 kW (100 hp) catalytic converter was developed in 1992 for the Peugeot 106 Rallye.

TU3 

Peugeot Citroën PSA TU engine

The TU3 has a capacity of 1360 cc with a bore of 75 mm and a stroke of 77 mm. At the beginning there were also versions with a single or double carburetor . The electronic fuel injection was introduced in 1990 for the Citroen AX GTI and Peugeot 106 XSI, this made for an increase to 73.5 kW (100 hp) at 6600 min -1 . Versions with carburettor gave way to the versions with electronic fuel injection in 1992, while the sports versions were adopted in 1996.
