Engine Management Systems - Self Study Program 841003 PDF

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.
