description: The 1.8 TSI/TFSI engine of the EA888 family was designed and developed by AUDI AG and introduced in 2007. It is a 1.8-liter, four-cylinder gasoline turbocharged engine with direct fuel injection. The EA888 1.8 TSI and 2.0 TSI engines replaced the EA113 series 1.8-liter and 2.0-liter engines. The 1.8 TSI EA888 is continually refined and already has the three generations described below.

1.8 TSI EA888 Gen1
The 1.8TSI Gen 1 by Volkswagen's codes BYT and BZB was a replacement for the 2.0 TSI EA113 engine. This engine was developed from scratch; the 88 mm (3.46 in) cylinder spacing is the only common feature with the predecessor.

The engine is built around a grey cast iron cylinder block and crankcase. This is a strong and reliable material that also has good acoustic dampening properties. For vibration reduction, the crankcase was equipped with two chain-driven counter-rotating balance shafts. The engine block height is 220 mm now. The engine has a steel crankshaft with eight counterweights, new aluminum alloy pistons, and 148-mm-long connecting rods. The 1.8TSI Gen 1 has an aluminum 16-valve cylinder head with chain-driven double overhead camshafts. The intake camshaft has a variable intake valve timing adjustment system. There are four valves per cylinder (two intake and two exhaust valves). The intake valve diameter is 34.0 mm, the exhaust valve diameter is 28.0 mm, and the stem diameter for both valves is 6 mm. The valves are actuated by low-friction roller finger cam followers equipped with automatic hydraulic valve clearance compensation.

The engine has a variable-length intake manifold made of plastic and a BorgWarner KKK K03 water-cooled turbocharger integrated into a cast iron exhaust manifold. The turbocharger provides a maximum pressure of 0.6 bar (8.7 psi). The fuel is delivered by a direct fuel injection system with sequential solenoid-controlled six-hole fuel injectors. The ECU for the 1.8 TSI EA888 Gen1 is Bosch Motronic MED 17.5. The 1.8 TFSI engines for Audi applications (CABA, CABB, and CABD engines) feature the Fuel Stratified Injection (FSI) system and variable oil pump. The first generation of 1.8TSI EA888 was produced until 2010, but the second generation appeared already in 2008 (a year later after Gen 1 was released).

1.8 TSI EA888 Gen2
The engineers quickly worked on bugs and released the second generation in 2008. For some time, Gen 2 of the 1.8TSI engine was produced together with Gen 1, but the Gen 2 became the most widespread version. It has the next engine codes: CDAA, CDHA, and CDHB. The engine got a new steel crankshaft with a reduced diameter of the main journals (from 58 mm to 52 mm). There are new pistons and piston rings, which caused the major problem with high oil consumption. All engines are now equipped with a variable oil pump. In the rest, it is the same Gen1 engine with minor changes in small details and ECU tuning. The production of 1.8TSI Gen3 continued until 2015.

1.8 TSI EA888 Gen3
The 1.8TSI EA888/3, or Gen 3, was released in 2011. This engine was offered first for Audi vehicles and later for other brands of the VW Group. The third generation is a deeply redeveloped previous generation and almost the new 1.8-liter engine in the EA888 family.

The engine has a new light-weight cylinder block with thin walls. The new durable and light crankshaft now has only four counterweights. The pistons and connecting rods were also redesigned. The most noticeable difference is the new cylinder head. It is a 16-valve aluminum DOHC cylinder head with an integrated exhaust manifold. Both camshafts come with a variable valve timing system. In addition to that, there is a two-stage valve lift control switched after 3,100 rpm. The timing chain stays untouched, but the chain tensioner was replaced with a new one. The fuel system includes a combination of direct fuel injection inside combustion chambers and traditional multipoint fuel injection before the intake valves. The 1.8TSI EA888/3 is equipped with an IHI IS12 turbocharger. The maximum boost pressure of the new unit is 1.3 bar (18.8 psi).

The car model with longitudinal engine location has the following engine codes: CJEB, CJEE, and CJED; CJSA is a transverse engine. Four-wheel-drive vehicles usually have the CJSB engine version. The most common 1.8TSI Gen3 engines for the North American market are CPKA and CPRA
