Self Study Program 841003 – Engine Management Systems PDF free online

The origins of Volkswagen engine development can be traced back to a 1912 horizontally-
opposed air-cooled overhead valve aircraft engine designed and built by Dr. Ferdinand
Porsche in Austria. This great-grandfather of the air-cooled Volkswagen engine shared the same operating principles as the most modern 5 valve per cylinder watercooled
automotive engine.

Both engines are four-stroke reciprocating internal combustion engines and, although a
direct comparison cannot be made, the basic operating principles remain the same.

Technology moved the four-stroke engine from magnetos and carburetors, to ignition
coils, points, distributors, mechanical fuel injection, hydraulic fuel injection, electronic
ignition, electronic fuel injection, and finally to the combined fuel and ignition control of the
most modern Motronic engine management systems.

Motronic engine management systems use electronics to precisely monitor and control
every aspect of engine operation, thereby improving efficiency, power, and driveability,
while at the same time reducing fuel consumption and tailpipe emissions.

Motronic engine management systems control engine operation so precisely that it is no
longer possible to identify a separate emissions system. All functions previously identified
as emissions system functions are now components of Motronic engine management.

The intent of this program is to provide information that will yield a greater understanding
of engine management systems commonly in use, and the progression leading to the newest Motronic ME 7 systems.

Course goals

  • Review principles of engine operation
  • Explain the progression of engine management systems used by Volkswagen
  • Provide an in-depth understanding of both previous engine management systems, and
    the state-of-the-art engine management systems in use today
