Self-study programme 322 Service Training The 2.0l FSI engine with 4-valve technology Design and function 2The 2.0l engine is based on the tried and tested 827/113 series. Thanks to FSI technology (Fuel Stratified Injection), the 2.0l petrol engine has taken on a new dimension. FSI engines are more economic, cleaner and more responsive than multi-point injection engines. They also meet today’s requirements in terms of low consumption, environmental issues and increased driving fun. The Volkswagen 1.4-litre/77kW FSI engine, the pioneer in this new generation of petrol engines, demonstrated these advantages at the end of 2000 when it was used in the Lupo. It was then followed by the 1.6-litre/81kW FSI and 1.4-litre/ 63kW FSI in the Polo. This self-study programme should familiarise you with the new technical features of this engine. The self-study programme shows the design and function of new developments. The contents will not be updated. For current testing, adjustment and repair instructions, refer to the relevant service literature.

In February 2003, the 2.0l FSI engine with the code AXW, identical with the Volkswagen version, was installed transversely in the Audi A3. The following components have been further developed to meet the high demands fo
