Introduction
1
The turbocharged 2.0L 4V chain-driven AVS engine (CAEB)
described in this Self-Study Program is a development of
the 1.8L chain-driven engine (EA 888 family) introduced
in Europe in 2006. The 1.8L engine, known as the Stage 0
engine, was the basis for the chain-driven 2.0L 4 cylinder
engine (CCTA/CBFA) introduced in North America during
the 2008 model year.
This EA 888 family of engines is replacing the belt-driven
camshaft engines within the Volkswagen Group world
wide.
The 2.0L 4V chain-driven AVS engine is a further
development of the earlier CCTA/CBFA engine. The
cylinder block, crankshaft assembly and pistons of the
CCTA/CFBA engine are similar to those of the CAEB
engine. However, major changes to the cylinder head and
the addition of the Audi Valve Lift System (AVS) to the
exhaust camshaft of the CAEB distinguishes this engine
from the CCTA/CBFA engines.
Also included in this Self-Study Program is a description
of changes needed to make a non-AVS 2.0L 4V chain-
driven engine compliant with SULEV emission standards.
To see a brief description of the development history and
a specification comparison of the EA 888 engines, please
