EA888 or VW TSI turbo engines
The line of VW EA888 turbo engines was first shown in 2006 and is still installed on almost all mass models of the concern, produced under the brands Volkswagen, Audi, Skoda. There are four generations of these powertrains, or five if zero is also taken into account.
EA888 GEN1
In 2006, a new EA888 family was developed to replace the EA113 series turbo engines. Audi engineers took as a basis an old cast-iron block with a pair of balancer shafts, an inter-cylinder distance of 88 mm, a piston diameter of 82.5 mm and globally shook it up. Thanks to the different piston stroke of 84.2 and 92.8 mm, two working volumes were obtained: 1.8 and 2.0 liters. The compression ratio relative to the previous generation of engines has been reduced from 10.5 to 9.6.
The cylinder block is covered by a new aluminum 16-valve cylinder head with hydraulic lifters, there is FSI direct fuel injection, a KKK K03 turbine and a dephaser on the intake shaft. The gas distribution mechanism has undergone a thorough modernization in these engines: a combination of a belt and a modest chain between the camshafts has been replaced by three large chains.
The very first power units are sometimes referred to as gen0, but we have summarized them all in a single table:
1.8-2.0 TSI 16v (1798 cc, 82.5 x 84.2 mm), direct injection:
- BYT (160 hp / 250 Nm) for Audi A3 2 (8P), Seat Altea 1 (5P);
- BZB (160 hp / 250 Nm) for Audi A3 2 (8P), Seat Altea 1 (5P);
- CABA (120 hp / 230 Nm) for Audi A4 B8 (8K);
- CABB (160 hp / 250 Nm) for Audi A4 B8 (8K);
- CABD (170 hp / 250 Nm) for Audi A5 1 (8T);

- CCTB (170 hp / 280 Nm) for VW Tiguan 1 (5N);
On many Audi models, the engine is located longitudinally, which gave rise to separate modifications. CBFA, CCTA and CCTB engines for the US market and comply with ULEV 2, not EURO 4.
EA888 GEN2
Already in 2008, the production of power units of the EA888 line of the second generation began. There were no fundamental changes here, an innovation was a lightweight connecting rod and piston group, which was later modernized more than once in an attempt to rid these motors of the oil burner. Many owners put pistons from first generation engines, thus making a downgrade.
There was also an adjustable oil pump and the AVS system for changing the height of the exhaust valves, which, however, was not installed on all engine versions. Plus environmental standards EURO 5.
1.8-2.0 TSI 16v (1798 cc, 82.5 x 84.2 mm), direct injection:

- CFPA (160 hp / 300 Nm) for VW Amarok 1 (2H);
The 2.0-liter longitudinal units were equipped with AVS and had more torque. The CAEA and CAEB motors were intended for the US market and met the ULEV2 environmental standards.
EA888 GEN3
In 2011, the production of third-generation units began, and this time there were more changes. The cylinder block was lightened, there were two phase regulators, and the AVS system began to be installed everywhere. Combined fuel injection appeared: distributed fuel injection was added to the direct one.
Turbine KKK K03 gave way to IHI IS12 on 1.8-liter and IHI IS20 on 2.0-liter engines. There were also especially powerful modifications of power units with an IHI IS38 turbocharger.

EA888 GEN3b
In 2015, the EA888 series motors were once again upgraded, but not very much. Almost all components of the power unit have been updated, but each only a little. The most important change is the operation of the engine on the Miller cycle and the compression ratio of 11.6 instead of 9.6. The manufacturer also abandoned 1.8-liter engines, the only volume was 2.0 liters.
1.8-2.0 TSI 16v (1984 cc, 82.5 x 92.8 mm), FSI + MPI:

EA888 evo5
In 2024 the fifth generation of the series appeared, which the manufacturer calls evo5. The engines received direct injection with 500 bar injectors, a variable-geometry turbocharger and operation on the Miller cycle, and they work together with a mild hybrid system. These units are installed on the newest Audi models:
