Principles of an Internal Combustion Engine

COURSE NO: M03-051
Principles of an Internal Combustion Engine
Course Highlights

This online engineering course presents the operational principles and basic mechanisms of the internal combustion engine.


The power of an internal combustion engine comes from burning a mixture of fuel and air in a small, enclosed space. When this mixture burns, it expands significantly; building pressure that pushes the piston down, in turn rotating the crankshaft. Eventually, this motion is transferred through the transmission and out to the drive wheels to move the vehicle.


The automobile is a familiar object to all of us. The engine that moves it is one of the most fascinating and talked about of all the complex machines we use today. This machine is what we call the internal combustion engine.


This 3 PDH online course is intended for mechanical and industrial engineers, designers, manufacturers and anyone interested in gaining a better understanding of the basics of an internal combustion engine.
