, Instructor Manual: Chapter 1: Engine Operation
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.
CHAPTER OBJECTIVES
Upon completion of this chapter, the student should be able to:
Explain the principles of internal combustion engine operation.
Identify internal combustion engine parts by name.
Explain various engine classifications and systems.

KEY TERMS
BDC: Bottom Dead Center, referring to the location of the piston at the bottom of the
stroke
bimetal engine: Engines composed of cast iron block and aluminum heads
blowby: Gasses that escape past piston rings
companion cylinders: term given to pairs of cylinders found in engines with even number
of cylinders
compression ratio: the ratio at which the air fuel gas mixture is
compressed displacement: refers to the volume that the piston
displaces in the cylinder firing order: The sequence in which the
spark plugs fire in each cylinder
lower end: Refers to the location at the bottom of the block where the crankshaft and
bearings are located
TDC: Top Dead Center, referring to the location of the piston at the top of the stroke

CHAPTER OUTLINE
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
