PURPOSE AND PERSPECTIVE OF THE CHAPTER
The purpose of this chapter is to introduce students to the basic construction and operation of an internal
combustion engine. It describes the many engine components and how to identify the various pieces. Also
explained are the different engine classifications along with the different systems and how they work
together to keep the engine operating effectively.
N
CHAPTER OBJECTIVES
Upon completion of this chapter, the student should be able to:
U
• Explain the principles of internal combustion engine operation.
• Identify internal combustion engine parts by name.
• Explain various engine classifications and systems.

• In a simple one-cylinder engine, the reciprocating (up-and-down) motion of the piston is changed
to usable rotary motion by the connecting rod and crankshaft. A flywheel gives momentum to the
crankshaft between power strokes. Valves control the engine’s intake and exhaust. (PPT Slide 4)
• During one four-stroke cycle, the intake, compression, power, and exhaust strokes are completed.
This action takes 720°, or two crankshaft revolutions. (PPT Slide 5)
