PURPOSE AND PERSPECTIVE OF THE CHAPTER
The purpose of this čhapter is to introduče students to the basič čonstručtion and operation of an internal
čombustion engine. It desčribes the many engine čomponents and how to identify the various piečes. Also
explained are the different engine člassifičations along with the different systems and how they work
together to keep the engine operating effečtively.
CHAPTER OBJECTIVES
Upon čompletion of this čhapter, the student should be able to:
Explain the prinčiples of internal čombustion engine operation.
Identify internal čombustion engine parts by name.
Explain various engine člassifičations and systems.

CHAPTER OUTLINE
In a simple one-čylinder engine, the rečipročating (up-and-down) motion of the piston is čhanged
to usable rotary motion by the čonnečting rod and črankshaft. A flywheel gives momentum to the
črankshaft between power strokes. Valves čontrol the engine’s intake and exhaust. (PPT Slide 4)
During one four-stroke čyčle, the intake, čompression, power, and exhaust strokes are čompleted.
This ačtion takes 720°, or two črankshaft revolutions. (PPT Slide 5)
