Self Study Program 606 – Audi 1.8L and 2.0L TFSI engine

VAG SSP 606. This self-study program aims to familiarize yourself with the engine technical TFSI 4-cylinder EA888 engine line (3rd generation). Audi move to the third generation of its four engines EA888 success cylinders. The reasons for the new phase of development is emission standards more stringent (Euro 6) and, of course, consumption reduction requirements, accompanied by a reduction in CO emissions 2. The powertrain was in all respects redesigned from top to bottom.

In addition to downsizing the downspeeding * playing an increasing role. The “global engine” is produced at the factory Audi engines of Györ, Silao (Mexico) as well as in China. Here, the EA888 engine line is produced in Shanghai and Dalian will also subsequently produced in Changchun. Like its predecessor, the engine is available with a displacement of 1.8 l and a displacement of 2.0 liters. It is used on car  platforms and brands of the most diverse group. The range of engine performance is very broad.

Ingolstadt engineers have, during development, paid particular attention to the following points:

  • large number of identical parts for all engine versions
  • Reduction in engine weight
  • Reduction of engine internal friction
  • Increased power and torque accompanied by a reduction in consumption
  • Improved comfort features. In addition, the motors must be implemented in all markets, including those in fuel quality is poorer. The “global engine” also plays an important role for increasing hybridization.

You will find the precise technical description of engine development level 0 in the self-study program 384 “engine TFSI 4-cylinder 1.8l Audi chain drive.” You can notify you of changes between the development level 0 and 1 and 2 levels of development in the self-study program 436 “Changes to the engine TFSI 4-cylinder chain drive.”

New innovative technologies implemented are:

  • manifold integrated into the cylinder head exhaust
  • dual injection system with direct injection in the intake manifold
  • new compact turbocharger module with turbine housing cast iron, electric wastegate actuator and lambda probe upstream of the turbine
  • Innovative thermal management with full electronic control of the coolant

Educational objectives of this self-study program:

It focuses on the TFSI engine technology 1.8l. After processing this self-study program, you will answer the following questions:

  • What are the main technical measures carried out during the development of the line of EA888 engines?
  • How do new innovative technologies?
  • What’s new in the service area and service?
