Self Study Program 626 – Audi Basics of Engine Technology PDF free online

Audi engine technology is distinguished by continual advancement and development with the aim of improving efficiency. That is part and parcel of the customer’s continuing and growing enthusiasm for the vehicle. That alone produces a broad range of engines for a
wide diversity of demands and vehicle types. Added to that there are market-specific variations.

New engine technologies have been presented in the Audi selfstudy programmes for many years. The chief objective of doing so is to equip service organisation staff with an understanding of the numerous innovations and processes to a level beyond the information given in the worksop manual repair instructions.

This self-study programme follows an approach that supplements the previous objectives. On the pages of this self-study programme you will find information on the fundamental design and function of Audi engines and associated technologies. Numerous engine
subsystems are also presented and explained.

Learning objectives of this self-study programme

In this self-study programme, you will learn the fundamental basics of Audi engine technology. It forms the basis for Training Module ATA 201 P.2.

When you have worked through this Self Study Programme, you will be able to answer the following questions:

  • What types of engine are used at Audi?
  • How are the components of the engine’s mechanical and control systems constructed?
  • How do the components of the engine’s mechanical and control systems operate?
  • What engine subsystems are there and how do they work?
