INTRODUCTION TO WHEELED VEHICLE ENGINES
Often the maintenance needed on an engine requires a lot of knowledge and very little physical effort. This is
the kind of repair work that separates the good mechanics from the bad ones very quickly. Without the proper
knowledge, mechanics may work for hours before they correct a simple problem. Sometimes they may never
get an engine running correctly. A good mechanic that understands engines can repair one in a few minutes.
This subcourse is written with the intention of starting you on the correct road to becoming a good mechanic.
In it we describe the different engine parts and how they operate together to make an engine run the way it
should.
