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a thorough modernization in these engines: a combination of a belt and a modest chain between the camshafts has been replaced by three large chains.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:

• BYT (160 hp / 250 Nm);
• BZB (160 hp / 250 Nm);
• CABA (120 hp / 230 Nm);
• CABB (160 hp / 250 Nm);
• CABD (170 hp / 250 Nm);
• CAWA (170 hp / 280 Nm);
• CAWB (200 hp / 280 Nm);
• CBFA (200 hp / 280 Nm);
• CCTA (200 hp / 280 Nm);
• CCTB (170 hp / 280 Nm).

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.

• CDAA (160 hp / 250 Nm);
• CDAB (152 hp / 250 Nm);
• CDHA (120 hp / 230 Nm);
• CDHB (160 hp / 250 Nm);
• CCZA (200 hp / 280 Nm);
• CCZB (211 hp / 280 Nm);
• CCZC (170 hp / 280 Nm);
• CCZD (180 hp / 280 Nm);
• CDNB (180 hp / 320 Nm);
• CDNC (211 hp / 350 Nm);
• CAEA (180 hp / 320 Nm);
• CAEB (211 hp / 350 Nm).

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.

• CJSA (180 hp / 250 Nm);

• CPKA (180 hp / 250 Nm);
• CPRA (180 hp / 250 Nm);
• CJEB (170 hp / 320 Nm);
• CJED (144 hp / 280 Nm);
• CJEE (177 hp / 320 Nm);
• CHHA (230 hp / 350 Nm);
• CHHB (220 hp / 350 Nm);
• CHHC (230 hp / 370 Nm);
• CWZA (230 hp / 370 Nm);
• CXCA (220 hp / 350 Nm);
• CXCB (230 hp / 350 Nm);

• CJXH (290 hp / 350 Nm);
• CJXG (310 hp / 380 Nm);
• CYFB (292 hp / 380 Nm).

Not very often, but there are versions of engines equipped with a Garrett MGT 1752S turbine.

• CULB (180 hp / 320 Nm);
• CULC (220 hp / 350 Nm);
• CPLA (211 hp / 280 Nm);
• CPPA (211 hp / 280 Nm).

CPKA, CPRA, CPLA, CPPA, CXCA, CXCB and CYFB motors are only available for the US and Canadian markets.

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.

• CZPA (180 hp / 320 Nm);
• CZPB (190 hp / 320 Nm);
• DKZA (190 hp / 320 Nm);
• DGUA (186 hp / 320 Nm);
• CVLA (170 hp / 270 Nm);
• CVKB (190 hp / 320 Nm).

Separately, it is worth writing about the motors of the 3b family, the so-called second power class. These power units operate according to the standard cycle, and also retained a compression ratio of 9.6.

• CYRA (249 hp / 370 Nm);
• CYRB (249 hp / 370 Nm);
• CYRC (250 hp / 370 Nm);
• CYMC (252 hp / 370 Nm).
