Engine Audi III CJSA 1.8 TFSI A4

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.
