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 .

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 

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.

TU5 

The TU5 has a displacement of 1587 cc with a bore of 78.5 mm and a stroke of 82 mm. There are versions with eight and with 16 valves. The power ranges from 66 kW (90 hp) to 92 kW (125 hp). The TU5 was used by both Citroën and Peugeot in motorsport.
